What is Heat Stress Effects on Rice Pollen Viability about?
The study investigates the impact of terminal heat stress on pollen viability and yield attributes of rice, revealing that temperatures above 35 °C during flowering significantly increase spikelet sterility and reduce grain yield. Eleven rice genotypes were tested, showing over 90% spikelet sterility and a net yield reduction of approximately 30% due to heat stress. Scanning electron microscopy indicated a clear reduction in pollen size under high temperature conditions.
