以普通杏砧木和西伯利亚杏砧木为对照研究 4种桃亚属砧木对杏 1年生嫁接苗的生长势、POD活性及ABA含量的影响 ,结果表明 ,砧木间存在较大差别。碧桃砧杏苗生长势增强 ,POD活性减弱 ,ABA含量下降 ;圆桃砧和毛桃砧杏苗生长势减弱 ,POD活性增强 ,ABA含量增加 ,其中毛桃砧杏苗较对照的差异达到显著或极显著水平
The effects of 4 peach rootstocks on the growth potential, POD activity and ABA content of 1-year-old grafted seedlings of Apricot rootstocks were compared with that of the common apricot rootstocks and the Siberian apricot rootstocks. The results showed that there was a big difference between the rootstocks. The growth of Pseudostellaria ammodendron seedlings increased, POD activity decreased and ABA content decreased. The growth potential of round peach anvil and peach anvil apricot seedling decreased, POD activity increased, ABA content increased, and the difference between the peach anvil apricot seedlings was significant or extremely significant Level
