Abstract

Abstract: Exogenous Ca²⁺reduce the intercellular Ca^{2 +} of cucumber anthers and increase pollen germination percentage at high temperature, while the exogenous ABA have a reverse effect. Endogenous ABA contents in two line anthers ascend significantly linked with new protein formation after exogenous Ca^{2 +} and ABA treatment under 45℃. The results indicated that Ca^{2 +} and ABA signals can interact each other in cucumber uninucleate pollen stage anthers under high stress.
