摘　　要：本文研究结果表明，黑龙江省不同光温型品种（系）春化阶段低温效应较弱，并且多数供试材料在春化阶段通过后，具有低温短日效应。通过对１２份不同光温型品种（系）不同光温条件下主要感光和感温性状生态价分析，结果表明，光敏和温敏型材料的生态价变化均大于光钝和温钝型材料。The results indicate that the effects of low temperature in vernalization stage on 12 varieties and advanced lines of spring wheat in Heilongjiang province are very weak and most materials mentioned above have some low temperature and short day effect after vernalization stage. According to analysis of ecological values of all materials tested in this paper, change of the ecological value of types senstive to light and temperature is much greater than that of types insenstive to light and temperature under different conditons of light and temperatuer.
