摘　　要：为选育抗早花烤烟品种,设置4个播种期的大田试验,采用因子分析等方法,探讨烤烟品种(系)的光温特性。结果表明,七个烤烟品种(系)对光温反应的敏感程度为云烟87>NC89>K326>G80>中烟90>K346>HY06。苗期的有效积温和日照时数越少,烟株现蕾越早。烤烟品种(系)的光温特性可以分为两种类型:光温钝感型,如HY06、中烟90、K346;光温敏感型,如G80、K326、NC89、云烟87。从分析结果看,HY06是一个典型的光温钝感型品种。Light and temperature characteristics of tobacco varieties were investigated. Factor analysis was adopted in selecting premature-resistance to flowering by sowing seeds at four different dates. Results showed that the sensitivity to light and temperature of seven varieties were in the following order： Yunyan 87〉NC89〉K326〉G80〉Zhongyan90〉K346〉HY06. Low temperature and sunshine accumulation at seedling stage lead to earlier appearance of flower bud. Light and temperature characteristics of tobacco varieties could be divided into two types. One responded slowly to light and temperature, such as HY06, Zhongyan90 and K346, and the other responded quickly such as G80, K326, NC89 and Yunyan 87. Result also showed that HY06 was a typical variety which responded slowly to light and temperature.
