概括
对来自印第安纳州西北部两个地点的玻璃花 Andropogon scoparius 进行了水培测试，测试其对锌和铜的耐受性。两个地点的植物都表现出对锌的连续反应，涵盖抑制到增强根生长的范围。市区工厂未受到下午 0.025 点的影响。铜，而农村工厂在此水平上受到不利影响。下午 0.1 点，乡村植物的根系生长速度比城市植物要快。铜。下午 0.025 点和 0.05 点铜，城市植物表现出更大的根系生长。 0.075 和 0.l p.p.m.铜，两个地点的植物表现出相同的根系生长。结论是，城市植物对低铜水平（0.025 p.p.m）具有耐受性。
Summary
The glass, Andropogon scoparius, from two sites in northwestern Indiana was tested hydro-ponically for tolerance to zinc and copper. Plants from both sites showed a continuum of response to zinc, spanning the range of inhibition to enhancement of root growth. The urban plants were unaffected by 0.025 p.p.m. copper, whereas the rural plants were adversely affected at this level. The rural plants exhibited greater root growth than the urban plants at 0.1 p.p.m. copper. At 0.025 and 0.05 p.p.m. copper, the urban plants exhibited the greater root growth. At 0.075 and 0.l p.p.m. copper, the plants from both sites exhibited the same root growth. It was concluded that the urban site plants possess tolerance to low (0.025 p.p.m.) copper levels.
