根腐线虫是植物三大病原线虫之一,广泛分布于世界各地,为害多种粮食及经济作物,给农业生产带来巨大损失。根腐线虫的识别与鉴定是防治工作的重要环节,研究植物线虫抗性机制有利于培育抗性品种。为此,回顾了近年来根腐线虫鉴定及植物对根腐线虫抗性方面的研究工作,强调了线虫准确鉴定的重要意义,分析讨论了植物抗线虫的机制。 Root-rotting nematodes are one of the three major pathogenic nematodes of plants. They are widely distributed in various parts of the world and are harmful to many kinds of food and cash crops, causing huge losses to agricultural production. Identification and identification of root rot nematode is an important part of prevention and control work. Studying the mechanism of plant nematode resistance is conducive to cultivating resistant varieties. Therefore, the review on the identification of root rot nematodes and the resistance of plants to root rot nematodes in recent years are reviewed. The importance of accurate identification of nematodes is emphasized. The mechanism of plant resistance to nematodes is analyzed and discussed.
