Abstract
Alectra sessiliflora (Thunb.) seeds do not germinate spontaneously. Th is species is host-dependent since it requires a chemical stimulant fr om the host roots in order to germinate. Results with GR-7, a syntheti c germination stimulant, showed that the seeds are totally dependent o n a stimulant for germination. It was found that preconditioning of th e seed as well as the germination temperature play an important role d uring germination.
