(Department of Biology, Zhanjiang Normal College, Zhanjiang, Guangdong 524048,China) study on the resistance of tall fesuce and common centipedegrass to herbicide and fungi disease. Three kinds of herbicide, Basta, glyphosate and paraquat, were sprayed on leaves of tall fescue and com-mon centipedegrass to studytheirresistance .The results showed that, the resistance oftall fescuewas superiorto common centipedegrass, and the resistance to glyphosate, basta and paraquat lowered in turn in tall fescue. After being daubed Basta, tall fescue transformed withBargene could delay yellowing and lighten the degree of yellowing than that of con-trol. After challenge inoculation , the resistance to disease of tall fescue transformed withChi_Glugene was superior to that of control.


      马生健、宗久明、曾富华、吴志华、卢向阳等就高羊茅、假俭草对除草剂与真菌病抗性进行了研究,作者分别选择了3种常用的除草剂Basta、草甘膦和百草枯,分别对高羊茅、假俭草进行喷雾处理。结果表明:高羊茅对草甘膦、Basta、百草枯3种除草剂的抗性依次减弱,高羊茅较假俭草对Basta的抗性强。转Bar基因高羊茅与非转化组培苗对照涂抹Basta后,转化植株比对照表现出黄化时间推迟,黄化程度减轻。转pChi-Glu基因高羊茅与非转化组培苗对照挑战接种禾谷镰刀菌后,转化植株比对照表现出抗病性增强。
