摘要
运用苗期症状观察和点免疫杂交技术（ＤＩＢＡ）测定了河北承德地区制种用玉米品种掖单１０７种子ＭＤＭＶ的带毒率，并在此基础上于室内和田间采用几种不同方法进行种子处理的防病实验，结果表明，５０倍８３增抗剂、０．５％高锰酸钾、７０％乙醇、０．１％磷酸三钠及６０℃温水浸种均有一定的防治效果，其中以０．５％高锰酸钾１０ｍｉｎ及５０倍８３增抗剂２４ｈ浸种防效较好。由此说明。
Based on the test result of virus carrying rate of corn seeds,cultivar Ye107,with both seedling symptom observation and dot immuno binding assay(DIBA),we arranged laboratory and field experiments to determine the effects of different methods of seed treatment on MDMV infection. 2% NS 83,0.5% solution of Potassium Permanganate, 70% Ethyl Alcohol, 0.1% solution of tribasic Sodium Phosphate and warm water of 60 ℃ treatments showed certain effects, in which treatment with 0.5% Potassium Permanganate solution for 10 min and 2% NS 83 showed better results. Thus,seed treatment should be one of main methods to control epidemic of maize dwalf mosaic virus.
