Paper Abstract

This paper reports the biological effect and the laser parameter of laser induced mutation in the peanut seeds. Peanut seed were irradiated with laser Ar+ at 488nm, LD at 650nm and YAG at 1060nm. There were different dose from 0.128w/cm2 x 180s to 35.84w/cm2 x 3s. The ultrastructural of plumule cell of peanut seed irradiated were examined by transmission electron microscopy, and the agro-character of M1 peanut were observed. The result shows that different laser with lower dose can promote the peanut seeds growth; to get the same irradiating effect as shorter wavelength laser, long wavelength laser should be increased does; on the same irradiation does condition, the biological effect related to power density and time combined. With irradiation dose increased, the cells structure were destroyed seriously and the rates of seedling lethality increased.
