摘要
本试验以“圣砧一号”、“世纪星”、“新土佐”、“黑籽南瓜”为砧木,分别与薄皮甜瓜“玉美人”进行嫁接,采用靠接法,组成四个砧穗复合体,分别以自根“玉美人”甜瓜、“圣砧一号”、“世纪星”、“新土佐”、“黑籽南瓜”砧木作对照,共9个处理,在嫁接苗成活后,生长发育正常时,利用人工气候箱,对9个处理分别进行2h、4h、6h、8h、12h(小时)不同时间的低温处理。低温处理温度为3℃,以15℃为对照。结果表明:各处理之间,以嫁接“圣砧一号”和嫁接的“世纪星”处理在低温下脯氨酸积累较多,嫁接苗次之,自根甜瓜苗酶活性最低。表明嫁接能提高甜瓜幼苗的抗冷性,表现为低温胁迫后嫁接苗的脯氨酸(Pro)含量高,在各个处理中,以嫁接“圣砧一号”和嫁接的“世纪星”处理脯氨酸积累较多,说明耐冷性强于其他处理。适合生产中大面积推广。
Shijixiog, “No. 1 Shengzhen”. “Xintuzwa”and“Spanish gourd”were used as rootstocks for thin- skin melon（Cucumis melo L. ）“Yumeiren”, making up of four scion - rootstock compounds, self rootmelon“ Yumeiren”, “Shijixing”, “No. 1 Shengzhcn”, “Xintuzwa”and“Spanish gourd”were used as CK. nine treatments in all The nine treatments were handled with different time of low temperature including two, four, six, eight, twelve hours in culture box, when the growth and development were in normal after grafiing. Treatment tempera ture was 3℃, 15℃was used as CK. The rcsulis showed that. The Pro accumulation in “Shijixing”and“No. 1 Shengzhen” grafting melons was Highest. High Pro conten activity indicated that grafting can improve the chilling resistance. Thus grafting should be taking advantage of in large area.
