嫁接栽培对茄子黄萎病抗性及产量的影响

试验以赤茄,GS2,CRP和托鲁巴姆等4个野生茄子为砧木,以油罐茄、黑又亮、短把黑、快圆茄和二民茄等5 个山西省主栽品种为接穗,进行了茄子嫁接栽培的田间试验和果实品质的测试。结果表明:茄子嫁接成活率可达 88．5％以上;4个供试砧木中,托鲁巴姆对茄子黄萎病的抗病性最强;20个砧穗组合中,快圆茄／托鲁巴姆的综合指标最佳,与对照相比,发病率降低41．7％,总产量增加75．4％;嫁接株果实品质的主要指标没有下降。

Effect of Grafting Cultivation on Eggplant Resistance to Verticilliun Wilt and Yield

The experiment was carried out to study the effect of grafting cultivation on eggplant resistance to Verticillium Wilt and production in the field and the fruit qualities. The results showed: The survival rate of the grafted eggplant was more than 88.50%.Of the four rootstocks, the strongest resistant variety to Verticillium Wilt was Tolubamu. Of 20 stions,the synthetical index of Tolubamu/KuaiYuanQie was the best, whose rate of infection was 41.76% lower than that of the control. And its total yield increased by 75.42% .The main fruit quality indexes of the grafted plant didn't decrease.
