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 of this study show that the low temperature effect of vernalization stage of different light and temperature type varieties in Heilongjiang Province is weaker, and most of the tested materials have low temperature and short day effect after they pass through the vernalization stage. The ecological value analysis of the main sensory and temperature sensitive traits of 12 different light and temperature type varieties (lines) under different light and temperature conditions showed that the change of eco-value of the light-sensitive and temperature-sensitive materials was greater than that of the light-obtuse and dull-type materials.
