| 摘 要： | 以金冠58 为接穗，以果砧1 号为砧木，设一叶一心、二叶一心、三叶一心、四叶一心4 个不同生理苗龄处理，研究不同苗龄对番茄嫁接效果的影响。通过对操作难易程度、过氧化物酶（POD）和苯丙氨酸解氨酶（PAL）的活性变化、嫁接切口愈合组织细胞观察、定植后植株的生长情况及嫁接成活率等方面进行分析，初步确定番茄贴接的适宜嫁接苗龄为2～3片真叶期。

| Abstract: | Taking tomato variety‘Jinguan 58’as scion，‘Guozhen No.1’as rootstock，this study designed 4 treatments with different tomato seedling ages as 1 leaf stage，2 leaf stage，3 leaf stage and 4 leaf stage；and studied the effects of different seedling ages on tomato grafting．Through analyzing the difficulty degree of operation，activity changes of 2 enzymes POD and PAL，callus cells in grafted incision，plants growth situation after field planting，and survival rate of post grafting，etc.，the paper preliminarily determined that 2 and 3 leaf stages were the most suitable time for tomato seedling grafting． |
