摘　　要：研究了芦荟蒽醌类物质在人工增强UVB辐射条件下对大豆生长发育和生理生化的影响,旨在探索预防UVB辐射对植物伤害的新途径.结果表明:在增强UVB辐射条件下,叶面喷施蒽醌类物质的大豆,其株高、叶面积比分别比没有喷施蒽醌类物质的大豆增加;叶绿素含量略有增加、丙二醛含量降低,大豆的生长发育接近正常水平.为此,喷施芦荟蒽醌类物质可有效减少UVB辐射对大豆的伤害.Gradual depletion of stratospheric ozone layer has lead to increase of UVB radiation that reaches earthsurface. The enhanced UVB radiation would affect terrestrial plants in various extents. In order to explore new approaches to prevent or alleviate the UVB harm, the effects of Aloe;s anthraquinones on the growth and physiological indexes of soybeans in the field under Ultraviolet radiation stress have been investigated. The results show that the height, leaf areas of the soybeans＇ leaves sprayed with Aloe＇s anthraquinones increased separately, comparing with leaves without spraying Aloe＇s anthraquinones under Ultraviolet Radiation stress. The contents of chlorophyll increase and the contents of MDA decrease. The results prove that Aloe ＇ s anthraquinones components could absorb and consume a part of energy of Ultraviolet Radiation. The harm of Ultraviolet Radiation to plants could be reduced effectively by spraying Aloe＇s anthraquinones components on plant＇s surfaces.
