撑×绿杂交竹枯萎病是近年在广西发现的新病害,该病害传染迅速,可造成竹林成片枯死。通过对自然感病的植株组织分离培养并纯化菌落,获得镰刀菌属真菌的纯培养,以该菌株进行病害的田间人工诱发试验,无论是菌株营养体菌丝或繁殖体孢子,在无伤或有伤的情况下,笋期均可从幼嫩组织侵入,并能引起与自然相一致的症状病菌;经过对一年生病竹病变组织的分离培养试验和病竹周围表土内越冬病菌的分离培养试验,越冬后的病原菌(Fusarium oxysporum)均能存活,可成为来年病害发生的初次侵染源。
Support × green hybrid bamboo Fusarium Wilt is a new disease found in Guangxi in recent years, the rapid transmission of the disease can cause dead bamboo into pieces. By isolating and purifying the colonies of the naturally infected plant tissues, the pure culture of the Fusarium fungi was obtained, and the artificial test of the disease in the field was carried out. No matter the vegetative mycelium or the propagule spores of the strain, In case of wounding, the bamboo shoots can invade from the young tissue and can cause the symptoms of the same with the natural bacteria; after one year of diseased bamboo tissue culture test and disease-resistant bamboo around the surface of the overwintering pathogen isolation and culture test , After the winter pathogen (Fusarium oxysporum) can survive, can become the first year of disease incidence of infection.
