The influences of different concentrations of exogenous calmolulin and its antiserum on the pollen germination and growth of pear were studied on Pyrus pyrifolia varieties Imamuraaki and Hosui in vitro and in vivo. The application of10-7mol/L calmodulin could promote pollen germination and pollen tube growth in vitro,however,200-times diluted calmodulin antiserum showed inhibitory effect. The functions of calmodulin and its antiserum in pollen germination and pollen tube growth were further proved by selfing incompatibility reaction and in vivo experiment. The results suggest that calmodulin treatment can effectively boost pollen germination and pollen tube growth of pear during selfing incompatibility process.
