采用室内种子萌发试验研究了锑胁迫对苋菜、四九黄菜心、菠菜、四季青等4种蔬菜幼苗期生物量、叶绿素含量及种子萌发率的影响,结果表明:在种子萌发早期进行低浓度(10 mg/L、20 mg/L)锑处理,其萌发率高于对照,高浓度(40～100 mg/L)锑处理,萌发率低于对照;种子萌发后期,随着锑处理浓度的升高,其萌发率逐渐下降。试验证明低浓度锑处理可刺激蔬菜幼苗生长;而高浓度锑处理则对蔬菜产生毒害.

Using the experiment of seeds germination in door,effects of Sb on four kinds of vegetables such as biomass, chlorophyl contents, germination ratio were analyzed. The results showed that in early stage of seed germination, germination ratio was higher than control under the treatment of low concentration Sb （10 mg/L, 20 mg/L）,but it was lower than control under the treatment of high concentration Sb （40- 100 mg/L）.However, in advanced stage, the higher Sb concentration was, the lower germination ratio was. It was indicated that low concentration of Sb promo...
