摘要
通过电镜观察、传毒试验及抗菌素处理,首次摸清了木麻黄黄化丛枝病的病原为类菌原体(MLO)和类细菌(BLO)复合侵染;传病虫媒为菱纹叶蝉(传播MLO)和短头叶蝉(传播BLO)。
Two Causal agents and two insect vectors of Beef Wood (Asuarina equis-tifolia) witches'broom were found by electron-microscopy,transmission ex-periment and the treatment of antibiotic.The causal agents are'MLO' and 'B-LO',and the two insect vectors are Hishimonus sp.(transmits 'MLO')and Bythoscopus sp.(transmits 'BLO'). The consequence of the healthy and diseased plant's polyacrylamide gelclectrophoresis shows that the peroxidase isoenzymes activity of healthy plantis much stronger than those of the diseased plants,and all of the diseasedplants are lack of AIII active area. It was found that for the content of Cu,Fe,Mn,In,Mg in soil,thehealthy plant is 2—10 times more than those of the diseaesd plant and the di-seased symptoms disappeared after 3 months when the narrated above elementswere added. The comprehensive control methods such as pouring the antibiotic into thesoil,applying phosphate fertillizer and elimination of the insect vector are allefficient.The control efficiency reaches 55.62%.
