Parthenocarpy, Parthenogenesis, and Self-Sterility of Douglas Fir
Abstract:This article presents data which indicate that parthenogenesis may occur in Douglas fir, that so-called parthenocarpy is a normal result of nonfertilization, and that self-sterility is very high. If Douglas fir is self-sterile as suggested, it follows that any condition which prevents adequate cross-pollination will resnlt in a poor seed crop. Application of this possibility to young seed trees, isolated seed trees, and artificial stimulation of seed production is indicated.
