摘要
为全面认识普通小麦这一物种的日长反应特性和光周期类型,本文对1982—1985年在北京和贵阳的两个全国小麦生态试验点,采用31个不同生态型的普通小麦品种所做的小麦试验进行了分析,并报道了其中8个品种从播种—抽穗的生育进程。研究表明:从播种至生理拔节的生育进程可在长日条件下实现,也可在短日田间条件下完成。拔节后,也能在短日条件下抽穗。在一定温度的配合下,短日种植不一定延迟抽穗。小麦的生长发育过程中无独立的光照阶段,应属于中日性植物。普通小麦具有广泛的生态适应性。
For the sake of understanding comprehensively the propert of day-length reaction for the commum species of wheat (Triticum aestivu L.), experimental data of wheat ecology were collccled from field experiment arranged in different sowing stages in Beijing and Gui ang during 1982 -1985. The 31 varieties studied are in different ccot pcs. Growth and development process from rowing to heading of 8 varieties is reported in this article, indicating that the process from sowing to physio-elongating could be completed under either long-day conditions or short-day filed conditions . After ph., sio-elongation, plants could complete heading even in short-da. conditions. The species of wheat sowing in short-days will not be necessar to have a prolonged heading stage if there is a proper temperature with it. The wheat has not independent photophase in the process of growth and development. It should belong in a da-neutral plant. The common species of wheat has broad ecological adaptabilit .
