育种技术研究抗逆性鉴定方法研究对黄瓜低温弱光耐受性进行了研究,系统地调查分析了临界低温(日温15℃/夜温8℃)、偏低温(日温20℃/夜温12℃)和两种低温逆境与弱光(3000Lux)组合对黄瓜苗期光合作用等生理代谢的影响,以及由此产生的叶面积增长减慢和冷害症状发生发展的规律。研
Breeding Technique Study on Resistance Evaluation of Low Temperature and Poor Light To study the tolerance of low temperature and low light to cucumber, the effects of critical low temperature (15 ℃ / 8 ℃), low temperature (20 ℃ / night temperature 12 ℃) and the combination of two low temperature stress and low light (3000Lux) on the photosynthesis and other physiological metabolism of cucumber seedlings and the resulting law of slowed growth of leaf area and the occurrence of chilling injury symptoms. research
