Abstract

The inflorescences of 'Silver Queen' coconut were created with varying levels of KNO3 at three different stages of spathe opening to determine its different effect on the maturity of florets and variability of pollen.

KNO3 significantly prolonged the male phase applied at different concentrations and stages of spathe development.

However, Stage A had the shortest male phase (21.73 days) while stage C had the longest (23.07 days). Further, Stage A had the least number of days to 206 floret maturity (10.33 days)

On the other hand, KNO3 treatments significantly increased the duration of the male phase and the number of days to 206 floret maturity. However, the differences between the treated inflorescences were not statistically significantly.

The interaction effect between stage and treatments on the duration of male phase was significant but not on the number of days tp 206 floret maturity.

Percent pollen viability (overall viability and at 206 floret maturity) and pollen yield were not affected at all by the stage of floral development, the different levels of KNO3 treatment and their interaction.
