Abstract

By using a twoline hybrid rice combination, Liangyoupeijiu, several factors of plant type were estimated and environmental models for such factors at the heading stage were established with the data of eight ecological experimental sites in 2006 and 2007. According to the climatic data from 1951 to 2005, differences in such factors and their effects on plant canopy were analyzed for four rice cropping areas, including South China, the middlelower reaches of the Changjiang River, Sichuan Basin, and river valley in Yunnan, China. The thickness of leaf layer(the distance from pulvinus of the third leaf from the top to the tip of flag leaf) and distribution of leaf area can be used as candidate index for plant type of a rice canopy.

Key words： hybrid rice; plant type; model; ecological area; canopy structure; index
