Abstract: Alectra sessiliflora (Thunb.) seeds do not germinate spontaneously. This species is host-dependent since it requires a chemical stimulant from the host roots in order to germinate. Results with GR-7, a synthetic germination stimulant, showed that the seeds are totally dependent on a stimulant for germination. It was found that preconditioning of the seed as well as the germination temperature play an important role during germination. Sade van Alectra sessiliflora (Thunb.) ontkiem nie spontaan nie. Hulle benodig ’n chemiese stimulant wat deur die gas-heerplant se wortels afgeskei word. Resultate met GR-7, ’n sintetiese ontkiemingstimulant, het getoon dat die sade totaal afhanklik van ’n stimulant vir ontkieming is. Ontkiemings-temperatuur en vooraf-kondisionering van die saad speel ’n belangrike rol tydens die ontkieming van die saad.
