To study the effect of kernel size on size of seedling produced in the
nursery, nuts from nine wild trees and Thomas nuts were planted. Kernel
weights ranged from 1.21 to 5.61 grams; nut weight from 6.5 grams to
24.3 grams.
~Results~: With one exception where germination was poor, nuts with
small kernels produced small seedlings and nuts with large kernels
produced large seedlings. Under nursery conditions the need for
uniformly large seedlings for budding and grafting is apparent. The
results of this study indicated the desirability of using seed nuts with
large kernels for production of understocks.
