Abstract:

Bananas are subtropical and tropical areas important economic crops. Cold damage causes significant losses to banana production, because it originated in the tropics, no cold tolerance. Ethephon and low temperature stress are two factors of banana leaf chlorosis. In this study, it was performed that experiments of different concentrations of ethephon on the role of the banana leaf chlorosis at different temperatures. The results revealed that ethephon promoted banana leaf chlorosis at non-stress temperature and ethephon inhibited banana leaf chlorosis under low temperature stress.
