The Growth Analysis in the Kernel Filling Process of K-Type Hybrid 901 and Its Parent Wheat
摘要
Abstract
Using Matlab software, the grain filling process of hybrid wheat 901 and its parents was fitted by Richards equation W = A/(1 +Be-kt in order to study the characteristics of grain filling of the hybrid. The active grain growth period of the hybrid was 6 d longer than that of Shaan 229, and its final grain weight (43.7 g/1000 grains) was higher than that of Shaan229 (36.3 g/1 000 grains). N values of 901 and R205 were both less than 1, and their grain growth was faster in the early filling stage, while slower in the middle-late stage. N value of Shaan 229 was ＞1, and its growth was slower in the early stage and faster in the middle stage. The period of early stage of 901 was shorter and of middle-late stage was longer. The situation of Shaan 229 was totally reversed. For parents, the father plant R205 was similar to hybrid wheat 901, whereas its mother plant K3314A similar to Shaan 229. It has been found that Richards equation was more suitable for fitting the grain filling process of wheat than Logistic equation.关键词
