The effects and mechanism of He-Ne laser (5 mW-mm2) irradiation on the variation of morphs and structure, physiological metabolic activities and the DMA repair capacity in damaged wheat seedlings induced by enhanced ultraviolet-B (10.08 kJ-m2-d~1) radiation were studied. The pathway and mechanism of the DNA repair stimulated by He-Ne laser irradiation were indicated chiefly.
1) Under the enhanced ultraviolet-B radiation, the wheat seedlings shown the decreased height and leaf area, accu...
