以 5种茄科野生种为砧木 ,栽培品种七叶茄为接穗 ,研究了嫁接对茄子生物学性状及黄萎病抗性的影响。结果表明 ,5种砧木与接穗间都有很强的亲和性 ,嫁接苗成活率均在 95%以上。茄子嫁接后 ,不仅植株生长势强 ,根系、叶片、茎粗、株高和单果质量都明显优于自根苗 ;而且对黄萎病的抗性提高 ,其中以托鲁巴姆和粘毛茄为砧木的嫁接植株对黄萎病的抗性最强。根据砧木自身的生物学性状和对黄萎病的抗性程度 ,确定托鲁巴姆是嫁接茄子防治黄萎病的最佳砧木。此外 ,嫁接植株的果实在干物质、总糖、粗纤维和微量元素铁等的含量上无明显差异
The effects of grafting on the biological characteristics of eggplant and the resistance to Verticillium wilt were studied using five kinds of solanaceous wild species as rootstocks and the cultivated varieties of Hevea brasiliensis as scions. The results showed that the five kinds of rootstocks had strong affinity with scion, and the survival rate of grafted seedlings was above 95%. After grafting eggplant, not only the plant growth vigor, root system, leaf, stem diameter, plant height and fruit quality were significantly better than the self-rooted seedlings; and the resistance to Verticillium wilt increased, of which Tuolumbum and sticky mahogany Grafting of rootstocks showed the strongest resistance to Verticillium wilt. According to the biological characteristics of rootstocks and the degree of resistance to Verticillium wilt, it is determined that Tuolumbum is the best rootstock for grafting eggplant against Verticillium wilt. In addition, there was no significant difference in the content of dry matter, total sugar, crude fiber and trace element iron among the grafted plants
