Abstract
Shennong 014,a super rice variety,was treated with shading at full heading stage to study the effect of assimilate-supply capacity on major qualities of rice.The results showed that the shading increased flowers per panicle significantly and decreased grain weight.When treated with 90% shading,the 1000-grian weight and kernel setting rate on primary and secondary rachis-branches decreased.When treated with 70% and 40% shading,the 1000-grian weight and kernel setting rate on primary and secondary rachis-branches were more than those of control.The brown rice rate,polished rice rate and head rice rate increased generally when treated with 70% and 40% shading,and decreased when treated with 90% shading.When shaded by 90%,the chalky grain rate and chalkiness degree reached the highest values.The protein and fat content increased and amylase content decreased when treated by shading.
