摘要
小麦主茎叶数是器官建成生长发育年龄的重要标志。因此,小麦温光反应特性的差异,除表现在穗部器官建成速度与抽穗速度外,还集中表现在主茎叶片数上。研究表明主茎叶数的变异受品种遗传及温光环境的影响。在人工控制春化和光照条件下,所有供试品种的最少叶数十分接近于春性小麦的最少叶数,表明春性品种可能是小麦冬春性进化的基本型。
Leaf number on main stem of wheat is an important sign of growth and develop-ment age. The difference of thermo-photoperiod reaction among verieties is reflectednot only in ear development and heading date, but also in leaf number on main stem.The result showes that heredity and thermo-photoperiod condition affect the variationof les f number on main stem. In our experiment with 8 vernalization and 4photoperiod treatments it was found that the minimum leaf number of all 17 tested va-rieties is close to that of spring-varieties. It can be supposed that spring variety is thebasic type in vernal-winterness evolution of wheat.
