Abstract

Germinative response of fresh tomato (Lycopersicon esculentum Mill.), pepper (Capsicum annuum L.) and cucumber (Cucumis sativus L.) seeds were tested under heat stress conditions and exposed to pregerminative hydration-dehydration and heat shock treatments. Combinations of a cycle of partial hydration in water with heat shock (36°C or 38°C) for 1 hour produced the optimum increase on germination and thermotolerance in tomato and pepper seedlings. Concerning cucumber seeds, partial hydration in water up to 2 hours before the onset of germination was the best procedure for inducing heat tolerance. Optimal temperature under heat shock was 36°C for all species.
