摘　　要：以"华瓠杂3号"、"黑籽南瓜"和"中国南瓜57"为砧木,以"津春四号"黄瓜为接穗,研究嫁接苗伤流液对黄瓜生长的影响及嫁接苗愈合部位的组织形态观察。结果表明:"黑籽南瓜"和"华瓠杂3号"做砧木的植株长势要较"中国南瓜57"强,"华瓠杂3号"做砧木的嫁接苗伤流液对黄瓜苗的生长有明显的促进作用;嫁接苗愈合部位的组织结构观察显示,"华瓠杂3号"做砧木的嫁接苗维管束比"黑籽南瓜"和"中国南瓜57"的维管束发达。Using＇Chinese pumpkin 57＇,＇Chinese gourd miscellaneous No.3＇and Cucurbita ficifolia as rootstock and ＇Jinchun No.4＇cucumber as scion to research the effects of xylem sap about cucumber growth were studied,and the healing parts of grafting seeding were observed in anatomical morphology.The results showed that the trend of scion growth was Cucurbita ficifolia,＇Chinese gourd miscellaneous No.3＇as rootstock were better than ＇Chinese pumpkin 57＇.The xylem sap of＇Chinese gourd miscellaneous No.3＇as rootstock was the best one to promote grafting seedling of cucumber to grow significantly.The results of anatomical morphology of the healed sections of grafting seeding showed vascular bundle of grafting seeding which ＇Chinese gourd miscellaneous No.3＇was as rootstock was the best developed than ＇Chinese pumpkin 57＇and Cucurbita ficifolia.
