对于小麦的冬、春性类型在遗传上、生理上的差异及对春化和光周期的反应,国内外许多学者做了大量研究。Torao Gotoh等对冬小麦春化反应进行了基因分析。ΓepMaH研究了春性品种光周期反应的形态特征。国内外关于小麦主茎叶数,叶龄与穗分化进程的对应关系、生育阶段的划分也有许多研究。本文是在前人研究的基础上,应用不同类型品种,周年分期播种,研究小麦主茎叶片数及穗分化进程的变异,以探索冬、春性品种叶数及穗分化进程的形态指标,并以此划分生育阶段。
Many studies both at home and abroad have made a great deal of research on the genetic and physiological differences of winter and spring types and the responses to the vernalization and photoperiod of wheat. Torao Gotoh et al. Analyzed the vernalization response of winter wheat. ΓepMaH studied the morphological characteristics of photoperiodic response in spring varieties. At home and abroad on the main stems and leaves of wheat, leaf age and spike differentiation of the corresponding relationship between the division of the fertility stage there are many studies. Based on the previous researches, this paper studied the variation of the number of main stem leaves and the process of spike differentiation in different types and varieties of wheat by annual staging to explore the morphological indexes of leaf number and spike differentiation in winter and spring varieties, And to divide the fertility stage.
