CHAPTER XVI

MISCELLANIES

There yet remain several phases of grape-culture essential to success,

none of which quite deserves a chapter and none of which properly

falls into any of the foregoing chapters. The subjects are not closely

related, are by no means of equal importance, yet all are too

important to be relegated to the limbo of an appendix and are,

therefore, thrown into a chapter of miscellanies.

CROSS-POLLINATION

The blooming of the vine had little significance to the grape-grower,

the blooming period being so late that grapes are seldom caught by

frost, until the discovery was made that many varieties of grapes are

unable to fertilize themselves, and that failure of crops of these

varieties was often due to the self-sterility of the variety. Until

this discovery, the uncertainty attending the setting of the grape in

these varieties was one of the discouragements of grape-growing.

Following investigations of the self-sterility of the tree-fruits, an

investigation of the grape showed that the vines of this fruit are

often self-sterile. This knowledge has in some degree modified the

planting of all home collections and has more or less affected the

plantings of commercial sorts.

Varieties of American grapes show most remarkable differences in the

degree of self-fertility. Many sorts fruit perfectly without

cross-pollination. Others set no fruit whatsoever if cross-pollination

is not provided for. Most varieties, however, are found in groups

between the two extremes, neither self-fertile nor self-sterile.

Figure 51 shows staminate and perfect clusters on one vine. Some

varieties show no variation in the degree of self-sterility or

self-fertility; others behave differently in regard to these

characters under different environment. Now and then the widest

variations are to be found in a variety in respect to self-fertility.

[Illustration: FIG. 51. Staminate and perfect clusters on one vine;

_right_, staminate; _left_, perfect.]

Following the lead of Beach at the New York Agricultural Experiment

Station, several workers have made careful studies of the

self-fertility of the grape, and now the cultivated varieties of

native grapes are divided into four groups in accordance with the

degree of self-fertility. Class I includes self-fertile varieties

having perfect or nearly perfect clusters; Class II includes

self-fertile varieties having clusters loose but marketable; Class III

includes varieties which are so imperfectly self-fertile that the

clusters are generally too loose to be marketable; Class IV includes

self-sterile varieties. The following is a list of commonly cultivated

grapes classified according to the divisions just given:

In the main, the cause of infertility, as with other fruits, is the

impotency of pollen on the pistils of the same variety. There are a

few cases in which pollen does not seem to be formed abundantly, but

these are very few. There are a few cases, also, in which the pistil

does not become receptive until after the pollen has lost its

vitality; these, however, are very few. In a greater number of cases

the pollen is found defective. However, dismissing all of these as the

exception, the rule is that self-sterility is due, as has been said,

to the lack of affinity between pollen and pistils produced on the

vines of some varieties.

Nature is helpful to the grape-grower in giving a guide to

self-fertility. The length of stamens is a fairly safe indication of

self-fertility. All grapes which are self-fertile bear flowers with

long stamens, although the latter are not a sure sign of

self-fertility, as a few varieties with long stamens are self-sterile.

On the other hand, short or recurved stamens are always associated

with complete or nearly complete self-sterility.

The remedy for self-sterility is inter-planting. Only the varieties

named in Classes I and II in the foregoing classification should be

planted alone. The sorts named in Classes III and IV must be planted

near other sorts which bloom at the same time in order that their

flowers may be cross-pollinated.

It is evident that the grape-grower must have some knowledge of the

relative time that grapes bloom, if he is to plant intelligently to

secure cross-pollination. The following table, taken from Bulletin 407

of the New York Agricultural Experiment Station, shows the blooming

time of grapes at that Station. Variations due to location and season

must be expected, but within the bounds of the regions in which these

grapes are grown variations will be slight. When this table is used

for other regions than New York, it must be borne in mind that the

farther south, the longer the blooming season; the farther north, the

shorter the season.

_Blooming dates of grapes._

From three years' records, the average length of blooming season for

grapes was twenty days, nineteen days in 1912 and 1914 and twenty-two

days in 1913. The first date in the average year of 1912 was June 14,

while for 1914, it was June 7:

RINGING GRAPE VINES

The ringing of woody plants is a well-known horticultural practice.

Three objects may be attained by ringing: unproductive plants may be

brought into bearing by ringing; the size of the fruits may be

increased and thereby the plants be made more productive; and the

maturity of the fruit may be hastened. In European countries, ringing

has long been practiced with all tree-fruits and the grape, but in

America the operation is recommended only for the apple and the grape

and with neither fruit is ringing widely practiced. Experiments

carried on at the New York Agricultural Experiment Station by Paddock,

as reported in Bulletin 151 from this Station, show that ringing may

well be practiced by grape-growers under some conditions. Since

Paddock's experiments, and possibly to some extent before, the grape

has been ringed to produce exhibition fruits or a fancy product for

the market.

Ringing consists in taking from the vine a layer of bark around the

vine through the cortex and bast of the plant. The width of the wound

varies from that of a simple cut made with a knife to a band of bark

an inch in diameter. The operation is performed during that period of

growth in which the bark peels most readily from the vine, the period

of greatest cambial activity. The term "ringing" is preferred to

"girdling," a word sometimes used, since the latter properly

designates a wound which extends into and usually kills the plant.

The theory of ringing is simple. Unassimilated sap passes from the

roots of the plant to the leaves through the outer layer of the woody

cylinder. In the leaves this raw material is acted on by various

agents, after which it is distributed to the several organs of the

plant through vessels in the inner bark. When plants are ringed, the

upward flow of sap is continued as before the operation, but the newly

made food compounds cannot pass beyond the injury, and therefore the

top of the plant is supplied with an extra amount of food at the

expense of the parts below the ring. The extra food produces the

results noted.

It turns out in practice that ringing is usually harmful to the plant,

as one might expect from so unnatural an operation. Injury to the

plant arises from the fact that parts of the vine are starved at the

expense of other parts; and because, when the bark is removed, the

outer layers of the woody cylinder dry out very quickly and thus check

to some extent the upward flow of sap through evaporation from the

exposed wood. Thus, not infrequently, the plant's vitality is

seriously drained. Nevertheless, vineyards may be found in which

ringing has been extensively practiced many seasons in succession and

which continue to yield profitable crops, the growers having learned

to perform the work of ringing so as to injure the vines but little.

Ringing without harm to the plant depends much on the way in which the

vines have been pruned. For instance, if the vines are pruned to the

two-arm Kniffin method, the ringing of bark should be done from both

arms just beyond the fifth bud. Thus, the ten buds left on the vine

produce enough leaf surface to supply the food necessary to keep the

vine in vigorous condition. When the four-arm Kniffin method is used,

the two top arms only are ringed, and even so three or four buds must

be left on each for renewals. Whatever the method of training, it will

be seen from these examples that some unringed wood must be left to

the vine with which to supply leafy shoots to support the vine. Some

growers ring their vines only every other year, thus giving them an

opportunity to recover from whatever loss of vigor they may have

sustained in the season of ringing.

Several other considerations are important in ringing: First, the

vines must not be permitted to carry too large a crop. Again, the

amount of fruit on the ringed portion of the vine must depend on the

amount of leaf surface not only of the plant but of the ringed arms,

each ringed arm acting somewhat independently so far as its crop is

concerned. If too many clusters are left on the ringed arms, it always

follows that the fruit is inferior and often worthless. Lastly, all

fruit between the rings and the trunk must be removed, for it does not

mature properly and so adds only to the drain on the plant's vitality.

As to the results, it is certain from the experiments that have been

conducted and from the experience of grape-growers, that the maturity

of the fruit is hastened, and berries and bunches are larger when the

ringing has been done intelligently. Many growers hold that fruit

produced on ringed vines is never quite up to the mark in quality and

in firmness of fruit. There seems to be a difference in opinion about

this falling off in quality, however, although unquestionably, choice

sorts, as Delaware, Iona and Dutchess, suffer more or less in quality.

It is commonly agreed, also, that varieties, the fruits of which crack

badly, as the Worden, suffer more from cracking on ringed than on

unringed vines.

Experiment and experience prove that the best results of ringing are

obtained if the work is done when the grapes are about one-third

grown. Of course the exact time depends on the season and on the

variety. The operation is variously performed and is easily done with

a sharp knife, but when large vineyards are to be ringed the grower

ought to provide himself with some simple tool. Paddock, in the

bulletin previously mentioned, pictures two of these tools and these

are reproduced in Fig. 52.

[Illustration: FIG. 52. Tools used in ringing grape-vines are shown in

1 and 2; while 3 and 4 show ringed vines at the beginning and the

close of the season.]

In conclusion it must be said that it is doubtful whether the gains

attained by ringing offset the losses. The practice is chiefly of

value only when exhibition clusters of grapes are wanted or when it is

necessary to hasten the maturity of the crop. Always, however, the

work must be performed with intelligence and judgment or the losses

will offset the gains.

BAGGING GRAPES

In some localities bagging is considered an essential to profitable

grape-growing. The bags serve to protect the grapes against birds. In

some grape regions vineyards suffer more from the depredations of

robins and other birds than from all other troubles. Grapes bearing

small berries and having tender pulp and those which shell most

readily from the stem suffer most. Of standard sorts, Delaware is

probably more enticing to robins than any other variety. There is only

one way of preventing damage to grapes from birds and that is by

bagging the clusters.

Bagging is also an effective means of protecting the grape from

several fungi and insects. In home plantations or small commercial

vineyards, bagging the bunches often eliminates the necessity of

spraying for fungi and for most of the insects that trouble the grape.

Because of the warmth afforded by the bags, bagged grapes ripen a

little earlier and are of somewhat higher quality than those not

bagged. Grapes bagged are protected from early frost, thus prolonging

the season. Grapes that have been protected from the elements during

the summer are more attractive than those exposed to the weather,

since the fruits are free from weather marks and present a fresh,

bright appearance, which puts them in a grade above unbagged grapes.

Bagging often enables the grower to sell his crop as a fancy product.

Grapes are bagged as soon as the fruits are well set, the sooner the

better if protection against fungi is one of the purposes. Under no

circumstances, however, should the clusters be bagged while in

blossom. A patent bag made for the purpose may be purchased or,

serving equally well, the common one and one-half and two-pound manila

bags used by grocers prove satisfactory. One of the patent bags which

is known as the Ideal Clasp Bag has a metal clasp attached to the top

for securing the bag in place over the cluster. In using the grocer's

bag, before it is put in place the corners of both the top and bottom

are cut off by placing several bags on a firm level surface and using

a broad-shaped chisel. Cutting off the corners of the top enables the

operator to close the bag neatly over the cluster, while cutting off

the corners of the bottom furnishes a means of escape for any water

that gets in the bag. In putting the bag in place, the top is pinned

above the lateral from which the bunch hangs, and must not be fastened

about the small stem of the cluster, as the wind blowing the bag

almost invariably breaks the cluster from the vine. The largest pins

to be purchased in dry-goods stores are used in pinning the bags. The

bags remain until the grapes are picked. Wet weather does not injure

bags and seemingly they grow stronger with exposure to sun and wind.

The cost of the bags and the work of putting them on is no small item.

To secure the best results, the work must be done at the period

between the dropping of the blossoms and the formation of the seeds,

when the grapes are about the size of a small pea. This is a busy time

for the grape-grower, which adds to the cost. When the work is

conducted on a large scale, the cost is about two dollars a thousand

bags, this figure covering both the cost of bags and labor. Women do

the work more expeditiously than men and soon become very skillful in

putting on the bags. Despite the trouble and cost of bagging, growers

seeking to produce a fancy product find that the expenditure proves

profitable.

WINTER-PROTECTION OF GRAPES

With a little care as to winter-protection, grapes may be grown

profitably in northern regions where, without protection, the vines

are killed or injured by low temperatures. Indeed, it is little short

of amazing how well grapes can be grown in northern regions where

nature wears a most austere countenance in winter, if hardy early

sorts are planted in warm soils and situations, and the vines are

covered in the winter. Occasionally one finds grapes grown profitably

in commercial vineyards in the northern states in regions where

protection must be given to prevent winter-killing, the extra work of

giving protection being more than offset by the high price received in

local markets for the fruit.

In all locations in which winter-protection must be given, several

other precautions are helpful or even necessary. Thus, cultivation

must cease early in the season, and a cover-crop be sown to help

harden and mature the vines. The grapes, also, must not be planted in

soils rich in nitrogen, and nitrogenous fertilizers must be applied

with care. The pruning should be such as does not induce great growth.

These simple precautions to hasten maturity often suffice in climates

where the danger of winter-killing is but slight, but where danger is

imminent the vines must be covered either by wrapping or by laying

down. Wrapping with straw may suffice for a few vines, but when many

vines are to be protected, laying them down is cheaper and much more

effectual.

By laying down is meant that the vines must be placed on the ground

and there be protected by earth and snow or other covering. It is

obvious that to protect thus, the vines must receive special training;

otherwise the trunks may be too stiff for bending. Some method of

training must be chosen in which renewals may be made rather

frequently from the ground so that if the trunks become large, clumsy

and unpliable, a more manageable trunk can be trained. If the

provisions for renewal are kept in mind, any one of the several

methods of training grapes explained in Chapter VIII on training may

be used.

Laying down must be preceded by pruning, after which the arms and

trunk are loosened from the wires and bent to the ground. Bending is

facilitated by removing a spade full of earth from the side of the

vine in the direction in which the vine is to be bent. The trunk is

then laid on the earth and sufficient soil placed on it to keep it in

place on the ground. If the danger of winter-killing is great because

of the tenderness of the variety or the austerity of the climate, it

often becomes necessary to cover the whole plant lightly with earth.

Small growers often make use of coarse manure, straw, corn-stalks or

similar covering, in which case the vines are held on the ground by

fence-rails or other timbers; but protecting with material that must

be brought into the vineyard is expensive and not more satisfactory

than earth.

The vines can be put down at any time after the leaves drop and before

the earth begins to freeze. It is more important that the vines be

taken up at the proper time in the spring. If uncovered too early and

cold weather follows, injury may result and more harm be done than if

the vines had not been covered. On the other hand, if the earth is

permitted to remain too long, foliage and vine are tender both to

sunshine and frost. A grape-grower in New York who has had much

experience in laying down vines in a vineyard of some thirty or forty

acres says that the work may be done at a cost of $6 an acre at the

average wage paid for farm-labor. It must be expected in a large

plantation, no matter how well the work of covering is done, that

occasionally a trunk will be broken, making it necessary to graft the

vine if a shoot does not spring up from below the break.

RIPENING DATES AND LENGTH OF SEASON FOR GRAPES

Every grape-grower should know when his varieties may be expected to

ripen and the length of season that they will keep. The commercial

fruit-grower by all means should have this information. It is not

sufficient that he know only roughly at what season his varieties

ripen; for, to take the turn of the market, he must know exactly when

a variety will ripen and how long it will keep. He needs this

information, also, that he may distribute his labor better throughout

the picking season.

Unfortunately, the data as to ripening time given by originators

and introducers of varieties are not always reliable. This

untrustworthiness of data is readily accounted for in several ways:

First, growers do not generally agree as to when grapes are ripe nor

as to how long they are fit to eat. Again, much confusion as to when

varieties ripen and how long they will keep arises from the fact that

grapes ripen at different times in different places, and it is

difficult for the grape-grower in Maine to make allowance in season

for varieties, the time of ripening of which is given for Maryland.

There are also other causes than the seasonal differences in grape

regions for variability in ripening time; thus, some soils are warmer

and quicker than others, and on these grapes ripen earlier.

Application of nitrogenous fertilizers may delay the period of

ripening somewhat. Grapes ripen perceptibly earlier on old plants than

on young ones. Lastly, every vineyard in a particular region has its

own particular climate caused by the lay of land, nearness to water,

air currents and altitude which cause small differences in ripening.

The following table taken from Bulletin No. 408 of the New York

Agricultural Experiment Station gives the ripening dates of grapes at

Geneva, New York. It is necessary that the reader know something about

the conditions affecting the ripening time at Geneva. The latitude is

42 deg. 50' 46". The altitude is 525 feet above sea level. The vineyard

lies a mile west of a relatively large body of water. The soil is a

cold heavy clay which must delay ripening time somewhat. The land is

level. The data are given as an average for three seasons, 1913-1915.

The figures given for "weeks in common storage" cover a variable

number of years, but for all varieties three or more years. The

grapes, after being picked, were at once placed in common storage in a

room on the second floor of a building. There conditions were not

ideal, and no doubt the season of storage would have been prolonged

somewhat had the fruit been kept in a better storage-room.
