Abstract

Simulation of rain at an equivalent rainfall intensity of 5mm/day during the flowering stage significantly reduced the effective pollination and seed set of rice variety IR36. A high percentage of unfilled grains was obtained when simulated rain was applied directly to the rice flowers, causing a significant yield loss of 18.32% per panicle on the average. Panicles which were enclosed in perforated plastic bags during the treatments and panicles which were not exposed to the rainfall treatment gave results which were not significantly different from each other.

The weight of 100 grains was not significantly affected. However, panicles under the simulated rainfall treatment have slightly lighter weight of seeds compared to panicles enclosed in perforated bags during the treatments and flowers not treated at all.
