不同嫁接方式对甜瓜幼苗生理代谢的影响

摘要

以厚皮甜瓜M101和M135为试材，研究了插接和双断根嫁接对甜瓜幼苗嫁接成活率和干重、根系活力、脯氨酸含量、丙二醛（ MDA）含量的影响。结果表明，双断根嫁接嫁接苗成活率高，根系活力强，脯氨酸含量明显比插接和自根苗高，叶片MDA含量降低，可在工厂化生产中推广应用。%Taking thick skin muskmelon varieties M 101 and M135 as materials, the effects of cuttage grafting and double root -cutting grafting on survival rate , dry weight , root vigor , proline and MDA contents of muskmelon seedlings were studied .The results indicated that the seedling survival rate of double root -cut-ting grafting was high , the root vigor was strong , the proline content was significantly higher than that of cut-tage grafting and self-root seedlings ,and the leaf MDA content decreased .The double root-cutting grafting method could be popularized in factory production .
