Abstract:
A study was made to investigate the temperature and pH at which maximum germination of pollen and growth of pollen tube take place in Carica papaya. Maximum germination and pollen tube growth were obtained at 2700 and pH 6.5. However, the differences among various levels of temperature and pH were statistically nonsignificant. To study the effect of genotype and the effect of temperature and pH over a wider range, 3x3 factorial experiments under three temperatures were planned in completely random design. Three dioecious male plants of papaya represented the genotypes. Effects of these factors were highly significant both for germination percentage and pollen tube growth. All the first degree interactions and the second degree interaction for both the variables were found to be highly significant as well.
