摘要
Abstract
The physiological indexes of rice (Oryza sativa L.) under enhanced UV - B radiation stress were measured, to study the effects of aloe's anthraquinones on its growth.The results showed that UV- B radiation affected the growth of plants significantly.The chlorophyll contents of the rice sprayed with anthraquinones of 1 mg/L and 10mg/L were increased by 24.5%and 17.8%, the POD activities were increased by 12.4% and 29.4%, and the contents of MDA were decreased by 50.5% and 21.9%, respectively, compared with that sprayed only with water.The REC of the anthraquinones-treated rice was reduced, and net photosynthesis rate was increased.Therefore the harm of UV - B radiation to plants could be reduced effectively by spraying aloe's anthraquinones on plant surface.关键词
