两种黄瓜接穗在同一砧木上对生长状况影响的研究

试验以黑籽南瓜为砧木，津优1号和农城4号为接穗的2种嫁接苗的生长状况进行了比较研究。结果表明：2种嫁接苗A-CK1和A-CK2，其最大侧根长的平均增长率分别为87.42%和47.13%；根系重量分别增加77.89%和67.51%；茎粗分别增加21.90%和14.25%。壮苗指数分别增加83.08%和78.83%；根/冠比A-CK1增加45.77%,A-C2略有增加。

Studies on effects of two cucumber scions on growth situation at same rootstock

In this experiment,blackseed pumpkin ( Cucurbita ficifolia ) was used as rootstock and Jinyou No.1 (CK 1) and Nongcheng No.4 (CK 2) were two scions,the growth situation of these grafted cucumber seedlings were studied.The results showed that the average raised ratios of the longest side root length of the two grafted seedlings (A-CK 1 and A-CK 2) were 87.42% and 47.13% separately,their root weight increased 21.90% and 14.25% separately,their index of high quality seedling increased 83.08% and 78.83% separately,the ratio of root-DW to shoot-DW of A-CK 1 increased 45.77% and the raised ratio of A-CK 2 was little.
