嫁接栽培对茄子黄萎病抗性及产量的影响

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

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。

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.
