远红外激光单独处理水稻种子,能引起处理二代性状突变。早熟突变率高于γ射线单独处理。株高、穗长、百粒重的广义遗传力高于γ单独处理,但突变类型数和总突变频率较低。γ射线加远红外激光复合处理二代的突变类型为两种单一处理之和,总突变频率为两种单一处理之和的2.47倍,早熟、矮杆的突变频率均较高,百粒重的广义遗传力比γ射线单独处理高。
Far-infrared laser treatment of rice seeds alone can cause the treatment of second-generation trait mutations. The rate of precocious mutation is higher than that of γ-rays alone. The general heritability of plant height, spike length and 100-grain weight was higher than that of γ alone, but the number of mutation types and the total mutation frequency were lower. γ-ray plus far-infrared laser compound treatment of the second generation of mutation types for the two kinds of single processing and the total mutation frequency of 2.47 times the sum of the two single treatment, premature, short pole mutation frequency are higher, 100-weight General heritability than γ-ray treatment alone.
