摘要
以无籽西瓜黑帝为接穗材料,采用田间试验、生理生化测定等方法,研究了不同砧木嫁接对西瓜生长过程中叶片生理指标及产量的影响,结果表明:不同砧木嫁接组合西瓜叶片叶绿素、MDA含量和PPO、NR活性在不同生育期表现有差异,其中以南瓜类型砧木西嫁强生和郑抗砧1号嫁接苗综合表现较为突出,其产量除与超丰抗生王嫁接组合差异不显著外,显著高于其他2个嫁接组合,且其可溶性固形物含量与其他嫁接组合间差异不显著。因此,西嫁强生和郑抗砧1号是无籽西瓜黑帝嫁接的优良砧木。
Using the seedlings of seedless watermelon variety “Heidi” as scion, we studied the effects of different kinds of stocks on the leaf physiological indexes and yield of grafted watermelon through field experiment＆amp;physiological and biochemical de -termination.The results showed that there were differences in leaf chlorophyll and MDA contents as well as PPO and NR activities a -mong different grafted combinations at different growth stages .The seedlings of grafted combinations from pumpkin stocks “Xi-jiaqiangsheng” and “Zhengkangzhen No .1” had more prominent comprehensive performance .The yields of these two grafted com-binations were not significantly different from that of the grafted combination from the stock “Chaofengkangshengwang”, but they were significantly higher than those of other 2 grafted combinations .There was no significant difference in soluble solid content a-mong 5 grafted combinations .So“Xijiaqiangsheng” and“Zhengkangzhen No .1” are the good stocks for the grafting of seedless wa-termelon variety “Heidi”.
