茄科植物抗青枯病特性研究及其应用展望

对 8个属 2 1种野生或栽培茄科植物的抗青枯病特性进行观测研究 ,筛选出水茄、乳茄、曼陀罗等 3种抗青枯病能力很强的物种。将番茄、烟草嫁接在水茄、乳茄上 ,嫁接苗也获得较强的抗病能力。将此结果结合现代抗病分子生物学技术及其研究成果 ,探讨这些抗性材料的抗病机理及其在抗病基因工程中的应用前景。

Study on the characters of some anti-disease species of Solanaceae and its application prospect

The resistance of 21 species of solanaceae to the disease caused by Pseudomonas solanaceaum Smith was observed. Among of 21 species,there are five species(L. chinese Mill,S. verbascifolium L.Sp.ed.,S. torvum Swartz)whose resistance to the disease is very strong. After grafting tomato on the five plants,we found that the grafting seedlings obtained the strong resistance to the disease too. According to this results,combined with the advanced molecular technology of biology and anti-disease gene engineering,some anti-disease mechanisms of the five plants and their application prospect were put forwand.
