摘要
通过水培试验，研究了Cu^2＋对荞麦种子萌发、幼苗生长及叶绿素、蛋白质含量的影响。结果显示：20-120mg／L Cu^2＋处理能促进荞麦种子发芽，发芽率逐渐提高，但效果不显著；显著抑制荞麦幼苗的生长，并且随着Cu^2＋处理浓度的增加，荞麦整株鲜重显著下降，尤其对根部的抑制最为明显。荞麦幼苗的可溶性蛋白质和叶绿素含量随着Cu^2＋处理浓度的增加呈先升后降的趋势。表明，低Cu^2＋浓度抑制荞麦生长，高Cu^2＋浓度则会对荞麦造成显著伤害。
The solution culture experiment was conducted to study the effect of copper on seed germina-tion, seedling growth and the contents of chlorophyll and protein of Fagopyrum esculentum Moench. The resuits showed that 20-120 mg/L Cu^2＋ could stimulate the seed germination and gradually increased the germination rate, but the effect was not obvious; they could obviously inhibit the seedling growth too, and the fresh weight of the whole plant decreased significantly with the increasing of Cu^2＋ concentration, especially they restrained the root growth. With the increasing of Cu^2＋ concentration, the contents of chlorophyll and soluble protein increased firstly and then decreased. As a result, the low Cu^2＋ concentration restrained the seedling growth, and the high Cu^2＋ notably damaged the Fagopyrum esculentum Moench.
