| 摘 要： | 本研究通过观测人工模拟马鞍山废矿石pH酸性环境对紫穗槐和黄檀种子萌发的影响，比较废矿石不同pH环境下种子萌发的变化，分析其酸敏感性差异。结果表明紫穗槐和黄檀是适应于当地pH值为2.4以上的废矿石酸性环境的低敏感树种，这二种植物对酸性废矿石环境的适应机制还需进一步的生理生态实验。

| Abstract: | In order to observe how acid environment of waste ore rock influences the seed germination of different species and the sensitivity of seeds to the acidity of waste ore rock, we designed the comparable groups of acidic solutions of different pH values to simulate the acidity of waste ore rock and examine the variations of seed germination for Amorpha fruticose Linn and Dalbergia hupeana Hance. We came to the conclusion that, at the pH value of above 2.4 for the indigenous environment of waste ore rock, Dalbergia hupeana Hance and Amorpha fruticose Linn are low acid-sensitive species. However, understanding their mechanisms of adaptation to the environment of acidic waste ore rock needs further physiological ecological experiments. |
