由尖孢镰刀菌油桐专化型(Fusariumoxysporum f.sp.aleuritidis)引起的油桐枯萎病,是油桐(Aleurites fordii Hemsl.)生产上一种具有毁灭性的病害。目前,在全国油桐主要产区均不同程度地受到该病害的严重威胁。选育抗病品种是防治植物病害的有效途径之一。几年来我们对油桐主要品种进行了抗病性鉴定,同时对接种方法也作了些探索。现将试验结果整理成文,以供参考。 Fusarium wilt caused by Fusarium oxysporum f.sp. aleuritidis is a devastating disease in the production of Aleurites fordii Hemsl. At present, the main producing areas of tung oil in the country are affected to a great extent by this disease. Breeding resistant varieties is one of the effective ways to control plant diseases. Over the past few years, we have made the disease-resistant identification of the main varieties of tung tree, and also made some exploration on the inoculation method. Now the test results are collated, for reference.
