Effect of Temperature and Radiation on Indica Rice Yield and Quality in Middle Rice Cropping System.

ABSTRACT: Rice (Oryza sativa L.) is cultivated in a wide range of climatic conditions, thereby inducing great variations in the rice growth, yield and quality. However, the comprehensive effects of temperature and solar radiation under different ecological regions on the rice growth, yield and quality are not well understood, especially in a middle rice cropping system. The rice growth, yield- and quality-related traits were investigated under different ecological regions. Among different areas, the days before the heading stage and after the heading stage of six cultivars ranged from 80 to 120 and from 30 to 50. The gaps of the grain yield, head rice rate, chalky grain rate and chalkiness level were about 1.2-52.4%, 1.0-3.0%, 2.7-12.7% and 0.3-4.5%, respectively. This study demonstrated that
