摘要
试验结果表明,硝基苯浓度达到27倍(0.34 mg/L)以上对水稻发芽产生明显影响,致使芽率下降。不同浓度的硝基苯对不同品种的发芽率影响不显著。随着浓度的增加,同一品种株高基本呈降低趋势,根数、叶片与对照差异显著。
The result of experiment showed ; effect of Nitrobenzene on germination was very large when concentration rate was 27 （0.34 rag/L）, germination of rice decreased. Effect of different concentration on germination rate of different cultivars was not large. The plant height tendency of the same cuhivar decreased when concentration was up. The difference of root number and leaves with CK was large.
