摘要:本试验通过选用 4 种不同番茄作为砧木对茄子进行嫁接,通过对其苗期田间热害指数、
超氧化物歧化酶、丙二醛、相对电导率、叶绿素的测定,分析番茄作为砧木嫁接茄子在苗期
耐热性的影响。结果表明,经嫁接后茄子苗在各个测定指标中均处于优势,耐热性增强。各
指标与田间热害的比较分析表明除叶绿素外超氧化物歧化酶、丙二醛、相对电导率可作为检
测苗期耐热性的指标。所试 4 个番茄品种中,L-402 为砧木嫁接的茄子在苗期各个测定指标
中都处于优势,表现出较高的耐热性。

Abstract: Taking four different tomato stocks as materials,this experiment studies the effects of
different graft stocks on heat-resistance of grafted seedling of eggplant through determining heat injury
index, SOD, MDA, conductivity and chlorophyll. The results showed that the heat-resistance of grafted
seedling of eggplant was stronger than that of self-root seedling and had an advantage over each index.
parative of each index and field heat injury shows that SOD, MDA and conductivity, except
chlorophyll, could be heat-resistance identification indexes at seedling stage of eggplant paring
heat injury index with other indexes. Judging from bined results of four different tomato stocks,
L-402 as resistant rootstocks,the grated eggplant was indexs of in a dominant position of m
