摘　　要：试验以大豆东农47和东农48为材料,采用盆栽的方式,研究干旱条件下增加UV-B辐射对大豆叶片光合色素的影响。结果表明,干旱胁迫使两个大豆品种的光合色素含量都显著降低;增加UV-B辐射也使两个大豆品种的光合色素含量降低,但差异显著性不同;干旱条件下增加UV-B辐射对东农47光合色素含量的影响表现拮抗作用,但对东农48叶绿素a和类胡萝卜素产生不利影响。Soybean Dongnong47 and Dongnong48 were used for experiment materials. Effects of UV-B enhancement on soybean photosynthetic pigments under drought stress were determined. The results showed that the contents of soybean＇s photosynthetic pigments were reduced observably under drought stress conditions, The effect of enhancement of UV-B radiation on photosynthetic pigments of the two varieties of soybean was different. With the enhancement of UV-B radiation, the antagonistic effect of drought stress on photosynthetic pigments of Dongnong47 was observed, but it was disadvantage for the chlorophyll a and carotenoid of Dongnong48.
