| 摘 要： | 以浙春 3号大豆 (Glycinemax)为试验材料 ,研究了不同浓度的Fe2 + 对大豆农艺性状的影响。结果表明 :过高浓度的Fe2 + 可抑制叶面积、叶比重的增加和根系的生长 ,使根系总根尖数、根总长和根表面积降低 ;但Fe2 + 浓度达 5 0 0mg/kg时 ,反而促进根系生长 ,这可能是植物的应激反应。

| Abstract: | The effect of the different supplementation of excessive Fe 2+ (100,300 and 500 mg/kg) on soybean(Glycine max)variety—Zhechun 3 growth was studied. The results showed that excessive Fe 2+ treatment significantly affected soybean growth. Fe 2+ stress decreased soybean leaf area and leaf specific weight. Low Fe 2+ toxicity inhibited growth of root and the stem, the length and the surface area of soybean roots all decreased, but the growth of root were promoted under the Fe 2+ level of 500 mg/kg. |
