1985—1988年在重庆对全国90个大麦入志农家品种进行了研究。按光温反应分为春性及冬性两大类型和6个亚类。不同类型品种光温反应的差异主要在出苗～拔节期。确定大麦早熟性除对春化要求、短日照敏感性外,应将温度对生长促进的差异也作为一项生理因素,并提出三联期是大麦对春化反应的敏感期及营养、生殖生长的转折点。
From 1985 to 1988, 90 varieties of barley into the country were studied in Chongqing. According to light and warm reaction is divided into two major types of spring and winter and six sub-categories. The difference of light and temperature in different types of cultivars was mainly in the emergence-jointing stage. In addition to the requirement of vernalization and short-day sensitivity, the difference of temperature and growth promotion should also be taken as a physiological factor to determine the precocity of barley and it is suggested that the triple phase is the sensitive period of barley to vernalization reaction and the nutrition and reproductive growth Turning point.
