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.

Key words: Acidic waste ore rock, Seed germination, Activity, Germination rate, Acidic sensitivity
