Abstract

A number of papers upon the germination of trees and shrubs have recently appeared, of which a few may be herein noted. P. W. Zimmerman of Boyce-Thompson Institute, in discussing influences affecting germination, calls attention to the early development of the embryo of the soft maple, while in the gingko the seed falls before the fertilization of the ovule has occurred. Notes upon the influence of drying and extreme temperatures upon many seeds are also recorded. Delayed germination in cases of rose, apple, hawthorn, cotoneaster, basswood and some junipers is attributed by him to immature embryos and hard seed coats.
