摘要:
为探索稀土元素镧和酸雨对大豆幼苗光合作用的复合影响，采用水培实验方法研究了La(Ⅲ)与酸雨(AR)复合处理对大豆幼苗叶片叶绿素含量(Chl)及光合速率(Pn)的影响。结果表明：在酸雨(AR1/pH3.0、AR2/pH3.5、AR3/pH4.0、AR4/pH4.5和AR5/pH5.0)单独作用下，Chl含量与Pn均低于对照组稀土La(RE1/20 mg.L-1 、RE2 /60 mg.L-1 、RE3/100 mg.L-1 、RE4/300 mg.L-1和RE5500 mg.L-1)单独作用时，2个指标均呈现“低促高抑”规律。RE +AR复合作用影响下，Chl含量与Pn低于CK值，且AR的pH越低，RE的浓度越高，抑制作用越明显。RE1和AR复合对大豆幼苗的抑制程度低于AR单独作用，呈拮抗效应，RE2~RE5与AR对大豆幼苗的复合影响表现为协同作用。
Abstract:
To explore the combined effects of acid rain and rare earth on photosynthesis，with soybeans cultivated under laboratory conditions as test materials，the effects of simulated acid rain and lanthanum on chlorophyll content (Chl) and photosynthetic rate (Pn) in soybean seedlings were studied.The results showed that under acid rain (AR1/pH3.0，AR2/pH3.5，AR3/pH4.0，AR4/pH4.5 and AR5/pH5.0) stress alone，Chl content and Pn were both inhibited.Under single La(RE1/20 mg.L-1，RE2/60 mg.L-1，RE3/100 mg.L-1，RE4/300 mg.L-1and RE5500 mg.L-1)treatment，the two indexes were both promoted under low concentration and inhibited under high concentration.With RE and AR combined treatments，Chl content and Pn had declined compared with the CK group.The inhibition degree was larger under lower pH value of AR and higher concentration of RE solution.Moreover，inhibition degree of the two indexes under RE1and AR combined treatment was lighter than that under AR or RE1 treatment alone，so they showed antagonistic action，while RE2-RE5and AR combined treatment showed synergetic effect.
