由山西省农科院棉花研究所研究员陈志贤同志主持研制出采用转基因的方法，将抗2，4—D类型除草剂基因转入棉花而育出抗除草剂的基因工程棉花，从而得遗传稳定的抗除草剂棉花品种。2，4—D类型除草剂对o子叶植物表面的蜡质层有较高的渗透力，并具内吸性，有较强的杀灭作用，棉花 By the Shanxi Provincial Academy of Agricultural Sciences Institute of cotton researcher Chen Zhi Xian presided over the development of the use of transgenic methods, the 2,4-D type of herbicide gene into the cotton and breeding herbicide resistant genetically engineered cotton, and thus genetically stable Herbicide-resistant cotton varieties. 2,4-D type herbicides on o-cotyledon surface waxy layer has a higher penetration, and internal absorption, a strong killing effect, cotton
