我们利用激光辐照和组培技术来试验提高激光的诱变效应和有效选择。经过近两年来对不同棉花品种的激光辐照、“电热刺激”等不同处理及其离体组织在不同培养基上培养的结果,初步发现:1.棉花离体培养的材料,CK生长最好,其次是“电热刺激”,激光处理的生长最差,同时,叶片有“褪绿”现象;2.红外激光辐照棉花表现组培材料生长 We use laser irradiation and tissue culture techniques to improve the laser mutagenesis and effective selection. After nearly two years of different cotton varieties of laser irradiation, “electric stimulation” and other different treatments and their in vitro tissue culture on different media results, preliminary found: 1. In vitro cultured cotton material, CK growth is best , Followed by “electric stimulation”, the worst growth of laser processing, at the same time, the leaves have “chlorotic” phenomenon; 2. Infrared laser irradiation of cotton tissue culture material growth
