低温弱光胁迫对甜瓜幼苗生长及生理指标的影响OA北大核心CSCDCSTPCD
Effects of Chilling and Low Light on Vegetative and Physiological Parameters of Melon Seedlings
以北方地区3个主栽甜瓜品种为材料,研究了低温弱光对甜瓜幼苗生长和生理指标的影响.结果表明,低温弱光胁迫下,甜瓜幼苗株高、茎粗、叶面积等形态指标迅速降低,分别比正常温光处理(CK)减少16.7％～20.0％、10.0％～13.5％和21.5％～20.2％,植株鲜质量和干质量分别比CK降低39.4％～51.7％和30.9％～45.1％,根冠比减少,幼苗的根系活力和叶绿素含量分别比对CK降低21.3％～42.4％和31.7％～41.5％,MDA含量明显…查看全部>>
Using three melon cultivars widely cultivated in North China as materials,the effects of chilling and low light on vegetative and physiological parameters of melon seedlings were studied. The results showed that morphological parameters (plant height,stem diameter and leaf area) and growth degree (fresh weight and dry weight) of the seedlings descended under the stress of chilling and low light. Compared with CK treatment (the normal temperature and light co…查看全部>>
