【摘要】 在弱光条件下测定了5个黄瓜品种的生理性状。结果表明,津优30号叶面积增加最多,津优2号较多,寒月居中,绿宁3号和北极星最少;津优30号和寒月叶绿素含量增加较多,绿宁3号和津优2号居中,北极星最少;寒月光抑制程度较轻;津优30号和津优2号光合产物转化受抑最轻,叶片淀粉累积量最高;津优30号干物重累积量最多,寒月较多,津优2号居中,绿宁3号和北极星最少。综合比较得出,津优30号的适应性最强,寒月、绿宁3号和津优2号居中,北极星适应性最差。更多还原

【Abstract】 The physiological characteristics of five cucumber varieties were measured under the poor light conditions.The results showed that the leaf area of Jinyou 30 was increased most,Jinyou 2 next,Lvning 3 and Beijixing were least.Chlorophyll content of Jinyou30 and Hanyue were increased considerably,Lvning 3 and Jinyou 2 were in the middle,Beijixing was least;Photoin-hibition of Hanyue was lesser extent.The transform of photosynthesis product of Jinyou30 and Jinyou 2 were inhibited little and leaf starch were accumulated at maximum.the plant dry weight of Jinyou30 were accumulated at maximum,Hanyue was next,Jinyou 2 was in middle,Lvning 3 and Beijixing were least.Comprehensive comparison showed that the adaptability of Jinyou 30 was strongest,Hanyue,Lvning 3 and Jinyou 2 were in the middle,Beijixing were worst.更多还原
