自1975年起,我们以水稻为诱变对象,采用不同的激光器件,对激光能否引起作用对象的生物学效应,特别是诱发可遗传的变异;激光诱变的效果及其影响因素等问题进行了探索,现将研究结果总结如下。 一、材料与方法 供试材料:有广陆矮4号、竹莲矮、湘矮早9号、古223、IR661、IR665、湘 Since 1975, we used rice as the mutagenesis object, using different laser devices, the laser can cause the biological effects of the role of the object, especially induced heritable variation; the effect of laser mutagenesis and its influencing factors and other issues Have carried on the exploration, the research result is summarized as follows now. First, the material and methods for the test materials: Guanglu a short 4, bamboo lotus short, Xiang short morning 9, the ancient 223, IR661, IR665, Hunan
