南瓜砧木对薄皮甜瓜生长发育、产量及品质的影响

Effect of pumpkin stocks on growth,development,yield and quality of grafted muskmelon

用7个不同南瓜砧木品种嫁接薄皮甜瓜,研究南瓜砧木对甜瓜生长发育、产量及品质的影响。结果表明:各嫁接组合植株生长势均优于自根苗,嫁接苗比自根苗早开花坐果;各处理产量差异显著,产量最高的是2号圣炎甜砧,比自根苗甜瓜增产69.93%;嫁接能降低薄皮甜瓜枯萎病和蔓枯病发生率。果实品质分析表明,嫁接苗甜瓜可溶性糖含量低于自根苗甜瓜,蛋白质和Vc含量高于自根苗甜瓜,粗纤维含量两者间无明显差异;各处理在果实大小、形状,果肉厚度、质地、风味上有明显差异。综合分析表明:1号012×023组合、2号圣炎甜砧适合作为薄皮甜瓜的嫁接砧木。

The effects of seven different pumpkin stocks on growth, development, yield and quality of grafted muskmelon were studied. The results showed that the growth and development of the grafted combinations were better than that of the self-rooted muskmelon, with earlier flowering and fruit setting. The yield of muskmelon showed significant difference. The Shengyan melon stock had the highest production in the all grafted combinations, which increased 69. 93% than before. And the muskmelon acquired resistance to the disease of Fusarium oxysporumf sp. Cucumerinum and Mycosphaerella melonis （pass.） ehlu et walker when grafted. The quality analyses indicated that the grafted muskmelon had lower soluble sugar content but higher protein and Vitamin C content than self-rooted muskmelon, with no significant difference of flesh fiber contents between them. All the combinations had significant difference in both appearance and taste, and 012 × 023 combination and Shengyan melon stock were recommended for rootstock on the muskmelon.
