将油菜发育的温度效应曲线化,以发育生理生态过程为基础,利用作物生理发育时间为尺度,系统地预测油菜的物候发育,包括出苗期、现蕾期、始花期、终花期、成熟期。模型中用来描述特定品种发育遗传差异的参数有温度敏感性、生理春化时间、光周期敏感性、基本营养生长期因子和基本灌浆期因子,前三者分别体现了不同油菜品种在热效应、春化作用、光周期反应方面的遗传特性,后两者分别体现了不同油菜品种的基本的营养生长期和灌浆期长短的遗传特性,5个遗传参数共同决定了不同品种到达各发育阶段的生理发育时间。
Based on the development of physiological and ecological processes, the temperature effects of rapeseed development were curveed. Based on the physiological development time of crops, the phenological development of rapeseed was systematically predicted, including seedling stage, budding stage, initial flowering stage, final flowering stage and mature stage. The parameters used in the model to describe the genetic differences of specific varieties were temperature-sensitive, physiological vernalization time, photoperiod sensitivity, basic vegetative growth stage and basic filling stage. The first three reflect the different effects of heat, Vernalization, and photoperiodic response. The latter two reflect the genetic characteristics of the basic vegetative growth and filling stages of different rape cultivars. The five genetic parameters determine the physiological characteristics of different cultivars at each developmental stage Developmental time.
