大樱桃外观鲜美,营养丰富,上市早,价格高,生长期短,管理简便,深受广大果农喜爱。但近年来大樱桃根癌病的危害日趋严重,由于未采取任何防治措施,仅剪掉根癌就栽至大田,致使许多樱桃园不仅长势不良,甚至大批死树。 大樱桃根癌病的致病菌为致瘤性土壤杆菌(Agrobcterium tumefaciens),该细菌在土壤中存活,并能在敏感植物的根系附近快速繁殖,从植株根茎处及根上的伤口侵入。侵入植株后将致瘤因子转移至植物细胞,致使这部分细胞无限制性分裂,形成一团未分化的瘤状组
Large cherry looks delicious, nutritious, early market, high prices, short growth period, management is simple, loved by the majority of farmers. However, in recent years, the damage caused by cherry root cancer has become more and more serious. Since no prevention and control measures have been taken, only the root canopy is planted in the field so that many cherry orchards not only grow poor but also die in large numbers. The pathogen of cherry tree disease is Agrobcterium tumefaciens, which survives in the soil and can rapidly multiply near the roots of sensitive plants, invading from wounds at the roots and roots of the plants. Invade plants after the tumorigenic factors transferred to plant cells, resulting in this part of the cells without restriction, the formation of a group of undifferentiated tumor group
