Abstract

Abstract: The effect of calmodulin antagonist W7 and Ca²⁺ on chilling resistance of eggplant seedlings were studied. Seed soaking with W7 distinctly enhanced the contents of electrolyte leakage and malondialdehyde (MDA) , reduced the activities of superoxid dismutase ( SOD) , catalase (CAT) and the content of soluble protein of eggplant seedling leaves under chilling stress , seed soaking with Ca²⁺ solution obviously decreased the contents of electrolyte leakage and MDA , increased the activities of SOD , CAT and the content of soluble protein of leaves. The result suggests that Ca²⁺-CaM messenger system plays an important role in controlling chilling resistance of eggplant seedling.

Key words: Calmodulin antagonist, Ca²⁺, Eggplant, Chilling resistance
