Research on the Grain Filling Characteristics of Two Fresh-eating Waxy Corn arieties
摘要
Abstract
[Objective]The purpose was to research the grain filling characteristics of the fresh waxy corn varieties. [Method] With 2 fresh waxy corn varieties of TNX0621and TNX0620 as the tested materials， their dry weights in the grain during the filling period were determined to study the basic law and characteristics of grain filling in 2 corn varieties. [Result] The measurement on dry matter weight in grain and Logistic curve fitting showed that of the grain filling rate of TNX0621 and TNX0620 displayed a "S-shaped" curve change of "slow-fast-slow" with the filling date. The grain filling rate of the two varieties all reached the maximum on the 34th d after filling and the biggest grain filling rates of 1 000-grain weight for mean daily increase were 8.57 and 6.43 g/d resp. The correlation test for the dry matter weight in grain and filling days indicated that r was relative at level of α =0.01 and there was a extremly significant relation between the dry matter weight in grain and filling days. The error analysis showed that TNX0621 had error at the range of y0621±4.027 d and TNX0620 had a error at the range of y0620±3.734 d， which accorded to the Logistic regress equation. [Conclusion] The grain filling characteristics of the fresh waxy corn was the important factors affecting the yield and quality of waxy corn.关键词
