| 摘 要： | 在自然条件下,Ca~(2 )对离体培养的番茄花柄脱落有抑制作用,而对经乙烯处理的则有显著的促进。无论是在自然还是乙烯条件下,未经任何处理的番茄花柄脱落过程中总钙与果胶酸钙含量下降,而水溶性钙含量升高,Ca~(2 )在不同程度上提高脱落过程中离区总钙、果胶酸钙和水溶性钙含量,尤其是在乙烯下的效果更显著,而经EGTA处理的则相反。

| Abstract: | Ca~(2 )suppressed abscission of tomato(Lycopersicon esculentum)pedicle in vitro under natural condition,on the contrary,it accelerated the process under ethylene condition.Under both conditions,total calcium and Ca-pectate contents increased and soluble Ca content decreased in abscission zone without Ca~(2 ) treatment.Ca~(2 )increased total calcium,Ca-pectate and soluble Ca contents in varying degrees,especially under ethylene condition.However,the effect of EGTA was opposite to Ca~(2 )under both conditions. |
