摘要
采用田间小区试验的方法,对引进的小西瓜品种从叶比重、光合特性、综合抗性、水分利用效率、产量和品质方面比较了其露地栽培的适应性。结果表明,3个品种中京欣在每个时期的叶比重、叶绿素含量较高,发病率较低;京欣的净光合速率比黑美人和京秀分别提高16.01%和26.37%,荧光参数Fv/Fm、Fv/Fo也高于黑美人和京秀,水分利用效率较二者分别提高14.3%和83.4%,产量和品质均优于二者,表现出很强的适应性,在生产上值得推广。黑美人的综合性状略低于京欣,也是一个可以应用的品种。
The leaf mass,photosynthetic characteristic,comprehensive resistance,water use efficiency,yield and quality of small watermelon varieties were compared by using field experiments.The results showed that Jingxin was superior than others in leaf mass,resist-disease and chlorophyll contents at different stages;Compared with Heimeiren and Jingxiu,the net photosynthetic rate increased 16.01% and 26.37%,respectively;Fv/Fm and Fv/F0 were increased,too.Compared with Heimeiren and Jingxiu,water use efficiency increased 14.3% and 83.4%,respectively,yield and quality were increased,too.Heimeiren was inferior to Jingxin,but both of them should be extended widely in our demonstration.
