Anther dehiscence, pollen viability and pollen germination of three mango cultivars with different fruit set characters

Abstract

Anther dehiscence, pollen viability and pollen germination on agar medium of three mango cultivars with different fruit set characters were conducted. The studied cultivars were Khiew Sawoey which naturally had low fruit set, Nam Dok Mai with moderate fruit set and Choke Anan with high fruit set. The results showed that Choke Anan had the highest anther dehiscence of 74.46% whereas Khiew Sawoey and Nam Dok Mai showed anther dehiscence of only 14.95% and 20.06%, respectively. All cultivars had high pollen viability between 81.33% - 91.29% and the germination of pollen was between 24.10% - 32.51%. The result indicated that poorly dehisced anthers is one factor which caused low fruit set in Nam Dok Mai and Khiew Sawoey cultivars.
