Abstract
After Nd:YAG laser irradiating on dry seeds of peanut at 1 060 nm,cytological effects and agro character in the F 1 generation have been studied in the present paper.The results showed there was chromosomal aberration of peanut tip cell induced with laser 35.84 W/cm 2 power density.With irradiating time added from 3 s to 8 s the rate of aberration increased from 0.16% up to 0.53%,and the types of chromosomal aberration also increased.Many aberration types,such as earlier separated mitosis metaphase,variability of number,sticky,non equal division,polypolarity division,nucleus protrudes to cytoplasm and so on were found in 8 s treatment but not in 3 s treatment.However,the dose of 35.84 W/cm 2×8 s leads to lethal dose according to the seeds sprouting and growing.On the seeds with 35.84 W/cm 2×3 s treatment,mine stem height,total pods per plant,mature pods per plant and pods weight per plant were more than the seeds unirradiated.
