不同类型玉米种子萌动吸水影响因素及其特点

为了探讨不同类型玉米种子在萌动前的吸水特点及其影响因素,本研究采用了9种类型共18个品种进行研究。结果表明:不同类型玉米种子,吸水动态符合对数函数y=alnx b变化曲线;但不同类型以及同一类型不同品种间吸胀动态有一定的差异;并且不同类型之间的吸水系数也存在很大差异;化学成分、胚乳质地、以及粒重对吸胀能力有一定影响,但化学成分是影响种子吸水能力强弱的主要因素。

Factors and Characteristics Affecting Water Uptakes of Different Types of Maize Seeds

The experiment was conducted with 9 different genotype maize seeds(18 hybrids) in order to study water uptake characteristics and the affecting factors of different genotype maize.The result showed that water uptake was fit the logarithm function y=alnx b,and there was no significant different in different varieties of the same type but significant in different types.There were significant differences among different types in water uptake coefficients.Chemical components,endosperm texture,and grain weight had effects on water uptake capacity.But chemical components were the dominant factor for water uptake capacity.
