Abstract

Germination success of Chlorocardium rodiei is low in large gaps. High light levels, however are beneficial for the survival of seedlings. (Partial) removal of cotyledons has a large negative impact on survival especially under low light conditions. Seedlings from large gaps are larger but not taller than those from the understorey, due to differential internode growth. Although growth of seedlings is improved by higher light levels caused for example by logging, great care should be taken with logging intensity, which may increase seed mortality.
