The review shows a clear research trend. Earlier studies focused on the effects of laser pretreatment on seeds germination, seedlings growth and physio-biochemical characteristics, with emphasis on the mechanisms by which laser pretreatment influences plants. Latter studies, on the other hand, focused on the effects of laser pretreatment on physio-biochemical traits of plants under such environmental stresses as drought, cold and enhanced UV-B radiation. In the latter research stage, more emphasis was placed on the effects of laser pretreatment under enhanced UV-B radiation on plants. Research results indicated that laser irradiance improved plant resistance to drought and cold stress, and enhanced UV-B radiation. On these bases, the mechanisms were discussed also. Future research should focus on repairing mechanisms of laser-pretreated plants under global eco-environmental change conditions.
