低温弱光对CMS三系辣椒幼苗形态指标与冷害指数的影响
Effects of Low Temperature and Weak Light on Morphology Indicators and Cold Damage Indices of CMS Three- lines Hot Pepper Seedlings
摘要
Abstract
With the cytoplasmic male sterile (CMS) line, restorer line and the corresponding hybrid as materials, the response of hot pepper (Capsicum annuum L. ) seedlings to weak light and low temperature and its recovery stage were studied in this paper. The results showed that low temperature and weak light led the seedlings to grow slowly or stop, and made the outer shape change partly. After treated under low temperature and weak light for 10 days, the plant height increased slowly or stopped, but the restorer line showed better endurance. The ratio of dry weight to fresh weight of leaves and aerial part declined firstly, afterward increased , then declined, and then increased again. In conclusion, the restorer line and hybrid of hot pepper had fewer damage symptoms in the external morphology.关键词
