| Abstract: | Experiments were carried out in 1997~1998 in Yongchuan of Chongqing to study the effect of interannual climate difference on ratooning rice of hybrid midseason rice. Light and temperature difference between the two years in main growing seasons and its effect on ear number, grain mumber and grain weight as well as its important role on the difference between years in yield and growing period were analyzed. The results of analysis have provided a basis for the development and improvement of ratooing rice. |
