When EGTA (Ca〓 chelator), Verapmil and LaCl〓(Ca〓 channel blockers) were used to treat tomato fruit at green mature and strawberry fruit at white stage with ethylene, they could reverse ethylene-induced increase in ethylene production in tomato and strawberry, PG activity, lycopene content, soluble protein content in cell wall in tomato and degradation in soluble protein in strawberry, which indicated blocking Ca〓 channel in plasma membrane or chelating Ca〓 can decrease intracellular Ca〓, further inhibite ethylene-induced maturation, ripening and senescence of fruit.

用质膜钙通道阻断剂异博定、钙通道Ca〓竞争性抑制剂以及Ca〓专一性螯合剂与乙烯一起处理绿熟期番茄果实和乳白期草莓果实，均可抑制乙烯诱导番茄和草莓的乙烯生成、番茄PG活性的提高、番茄红素含量的增加和细胞壁可溶性蛋白含量的增加以及草莓可溶性蛋白的分解，表明阻断质膜Ca〓通道或螯合胞外Ca〓以减少胞内Ca〓能抑制乙烯对果实的催熟作用，间接证明乙烯对果实成熟衰老的诱导与胞外Ca〓内流引起的胞质Ca〓浓度的增加密切相关，表明乙烯信号转导可能与钙信使有关，调节胞质Ca〓浓度可调节乙烯对果实的催熟作用。
