摘要
研究了不同pH值(1.0,2.0,3.0,4.0,5.0和6.5)酸雨对豇豆种子萌发及幼苗生长的影响。研究结果表明,随着pH值的下降,豇豆的发芽率、发芽势、发芽指数、幼苗根长及下胚轴长均呈降低的趋势,均受到不同程度的抑制。当pH值降到最低1.0(酸度最强)时,所有豇豆种子全部发生霉烂现象。
Effect of acid rain at different pH (1.0, 2.0, 3.0, 4.0. 5.0 and 6.5) On seed germination and seedling growth of Vigna unguiculata ssp. sesquipedatis (L.) Verde was studied. The results showed that seed germination rate, germinated vigor, germination index, seedling root length and hypocotyl length tended to decrease with the decrease in pH. All Vigna unguieulata ssp. sesquipedatis (L.) Verdc seeds were musty when pH was 1.0.
