嫁接对薄皮甜瓜耐盐性及果实品质的影响

为提高嫁接甜瓜的耐盐胁迫能力,以薄皮甜瓜金妃为材料,研究嫁接对甜瓜耐盐性及果实品质的影响。结果表明:嫁接可显著提高苗期生物量、耐盐胁迫能力及果实产量。世纪星、帝王新土佐砧木植株生物量、壮苗指数表现最佳。200mmol·L~(-1) NaCl胁迫下,帝王新土佐、铁力砧和青研砧木1号耐盐效果良好。产量表现方面,世纪星和铁力砧表现出色;果实品质试验表明,嫁接会导致果实中可溶性固形物含量、可溶性糖含量、可溶性蛋白含量降低及可滴定酸含量升高,进而导致甜瓜果实品质下降。

Effect of Grafting on Salt Tolerance and Fruit Quality of Oriental Melon

In order to improve the salt resistance of grafted melon,the oriental melon cultivar Jinfei was used to study the effects of grafting on salt tolerance and fruit quality on melon.The results showed that grafting significantly increased seedling biomass,salt tolerance and fruit yield.Shijixing and Diwangxintuzuo showed the best performance on biomass and seedling index;stock of Diwangxintuzuo,Tielizhen and Qingyanzhenmu 1 were identifyied to be the best salt resistance with 200 mmol·L-1 NaCl treatment;the yield of Shijixing and Tielizhen were higher than other varieties;but the fruit quality research showed that the content of soluble solid,soluble sugar and soluble protein decreased while titratable acid content increased after being grafted,consequently due to the decline of melon fruit quality.
