稀土对薇菜生长过程中营养物质及几种重要同工酶的影响研究

Effect of Rare Earth Micro-Fertilizer on Isozyme Patterns During Growth of Vetch

以富硒植物薇菜为对象 ,研究了用不同浓度的稀土溶液叶面喷施后 ,对植物宏观生长情况及其营养物质含量的影响 ,并采用聚丙烯酰胺凝胶电泳技术 ,对植物体内一些重要同工酶谱的变化进行了研究。结果表明 :适量的稀土能促进植物生长过程中糖及蛋白质的合成。在实验的浓度范围内 ,一些重要的同工酶谱发生显著的变化 ,其中某些谱带消失 ,又出现新的谱带 ;还能影响酶谱的强弱 ,与稀土浓度间具有一定的相关性 。

Effect of Rare Earth Micro fertilizer on isozyme patterns of three enzymes(Peroxidase,Catalase,Protease)during growth of vetch was investigated by utilizing PAGE methods.The results indicated:RE not only can make certain their some bands deleted but also can induce some new bands.Under the action of RE,it appeared the shade of POD bands was related to the rare earth concentration.Rare earth can affect the patterms widely and apparently.
