CHAPTER XIII.

Crossing or Hybridizing.

These expressions seem to be popularly used in a rather free way, as

applied to the gladiolus, to denote the bringing together of different

varieties, for the purpose of obtaining seed, which shall produce new

and diverse kinds, combining in some degree the qualities of the

parents, and presumably of superior excellence. Accepting the foregoing

terms in the sense alluded to, as meaning simply a mixing of stocks, or

of varieties, there are two ways of securing the desired results, the

natural and the artificial. In the former, insects and the wind do the

work; in the latter, it is done by hand. It may be worth while to speak

of these methods somewhat in detail, with the prefatory statement that a

variety is not supposed to reproduce itself from seed, and as a rule it

does not. Although there are instances in which seedlings bear a close

resemblance to a parent, or to each other, theoretically no two are

alike, and in reality there is a wide range of variation among those

grown from the same bulb. In this variation lies the charm of the work

and the secret of success.

Suppose the grower wishes to cross two varieties in the natural way. He

plants the bulbs near together and apart from others, far enough distant

so that their pollen cannot reach the blooms. Between the two there is

an interchange, each being fertilized by the other, and the results will

comprise as many variations as there are seeds produced. Several kinds

may be planted together in the same manner and the consequent

combination will be still more numerous and varied. If the amateur

wishes to save seed from his bed of mixed bulbs, he watches the blooms

as they come out and cuts and carries away any that are not desirable to

propagate from, so that they may not affect the seed of the others. By

this method all the seed saved is of a high grade of excellence, and the

new developments from it are exceedingly interesting.

When the grower purposes to cross two varieties artificially, he goes

about it early in the morning, when the blooms first open. He selects

the flower which is to be the mother parent, cuts away the stamens with

sharp pointed scissors, and then covers it with cheese capping, to keep

out strange pollen. From ten o'clock in the forenoon to about four in

the afternoon, the pistil secretes a honey-like liquid, which causes the

end or stigma to be moist. It is then said to be receptive, and the

grower carries the stamens from the other parent, and gently touches the

stigma with the anthers, causing the pollen to adhere.

Hand-hybridizing can be carried on in a garden, or any small area, while

special crossing done in the natural way requires a great deal of room.

The artificial method also has the advantage of being perfectly exact,

while in the other there is a possibility that pollen carried by bees

may be introduced, even at a considerable distance.

Whichever plan is adopted, the work is very fascinating, and if the

grower succeeds in attaining the realization of his ideals along the

lines he is pursuing, or even a near approach to those ideals, the

pleasure he experiences is ample recompense for all his efforts.
