番茄不同砧木嫁接亲和性与共生性研究

摘要

Five different tomato stock varieties(TA04,No.1baozan,TA08,No.1stock and Tolubamo)were used to graft with three different tomato scions(No.108 tomato,Ji’ao and Henly).The graft compatibility was judged by purvival percent and the graft symbiosis was confirmed by comparing the properties of grafting plants and scions including plant height,stem diameter,single fruit weight,fruit shape and yield.The results showed that TA04’s graft compatibility and symbiosis were the strongest and Tolubamo’s were the lowest among the 5 tomato stock varieties which should not to be used as tomato stock.The other three stocks were near the same.The results also showed that graft planting could effectivly guard against bacterial wilt and improve the output.%用5个不同的番茄砧木(TA04、宝砧一号、TA08、砧木一号、托鲁巴姆)分别与3个不同的接穗品种(108号番茄、吉奥、亨利)嫁接，通过对嫁接成活率调查，判断砧木的嫁接亲和性。嫁接植株种植后，通过株高、茎粗、单果重、果形及产量等性状与接穗实生苗植株对应的性状比较，判断砧木的嫁接共生性。结果表明：5个砧木品种中，TA04的嫁接亲和性与共生性最强，而托鲁巴姆相对较差，不宜作番茄砧木使用，其他3个砧木品种基本相近。同时表明嫁接栽培能有效减轻番茄青枯病危害，提高产量。
