试验在温光互作设计下,通过品种苗穗期(出苗—抽穗)对温光反应的变异分析看出,不同类型品种在不同温光组合下,不仅存在着最短与最长的苗穗期,而且不同类型品种,对温光反应类型不同,春性类型品种对春化基本无反应而对光长反应敏感;强冬性类型品种对春化反应敏感,而对光长必须在一定春化量基础上才表现敏感,并且具有短日代替春化效应。一般冬性类型品种(主要指黄淮麦区的半冬性过渡类型)多为温光兼敏性,无短日春化特性。 Under the temperature-light interaction design, through the analysis of the variation of temperature and light at the seedling stage (emergence-heading), we found that under different combinations of temperature and light, not only the shortest and longest seedling stage , And different types of varieties, different types of temperature and light reaction, the spring type of varieties of vernal basically no response to light-sensitive response; strong winter types of varieties sensitive to vernalization, and the light must be a certain vernalization Based on the amount of sensitive performance, and has short days instead of vernalization effect. Generally winter types of varieties (mainly Huanghuai region semi-winter transitional type) mostly warm and light sensitivity, no short vernalization characteristics.
