摘要
选用大麦为材料,研究不同Al3+浓度(50、100、500μmoL/L)对大麦(Hordeum vulgare L.)叶片和根的可溶性蛋白含量的影响。结果表明:在整个处理期间,高浓度Al3+(500μmoL/L)可诱导大麦叶片中可溶性蛋白,其含量明显高于对照组和其他处理组(除了Al3+浓度为100μmoL/L)(P<0.05)。Al3+处理20 d时,所有处理组叶片中的可溶性蛋白含量都显著高于对照组(P<0.05),并且呈现先上升后下降的趋势。在大麦根中,各个Al3+处理组可溶性蛋白含量随着处理时间的延长、处理浓度的增加呈上升趋势(P<0.05),但在Al3+处理20 d时,100μmoL/L Al3+处理组可溶性蛋白含量明显高于500μmoL/L Al3+处理组(P<0.05)。
With Hordeumvulgare L. as the material,influences on soluble protein contents in leaves and roots ofbarley（Hordeumvulgare L）tre.ated with different concentrations of AP＋（50,100,500 μmoL/L）were investigated.The results indicated that at high concentration of AP＋（500 μmoL/L）, the soluble protein contents in leaves increased high significantly when compared with control and other treatment groups （except for the treatment with 100 μmoL/L AP＋）during the whole treatments （P〈0.05） .The contents in leaves exposed to AP＋ for 20 days were high significantly in comparison with control （P〈0.05）.The soluble protein contents in roots exposed to AP＋ increased significantly with the increasing concentration and time. However,in the roots exposed to 100 μmoL/L Al^3＋ for 20 days was high significantly when compared with the treatment exposed to 500 μmoL/L Al^3＋（P〈0.05 ）.
