以不同Zn2+浓度(0、0.05、0.5、5、10、50、100、200 mg/L)的ZnSO4溶液处理青花菜种子，研究锌对青花菜种子萌发的影响.结果表明：青花菜种子的发芽指标随着Zn2+浓度的增加均表现出先升高后降低的变化趋势；相对发芽率、相对发芽势、发芽指数均在 Zn2+浓度为100 mg/L 时达到最大；活力指数、胚根长、胚芽长和生物量在10 mg/L时达到最大；当Zn2+浓度大于100 mg/L时，对青花菜种子萌发和生长起到抑制作用.

The seeds of broccoli were treated by zinc sulfate solution of different Zn2+ concentrations(0, 0.05,0.5,5,10,50,100,200 mg/L),thus the effect of Zn on seed germination of broccoli was studied.The results showed that all the values of germination indexes firstly increased and then decreased with the in-creasing of Zn2+ concentration.The relative germination rate,relative germination potential and germina-tion index reached to their maximum values when the concentration of Zn2+ was 100 mg/L,while the seed vigor index,radicle root length,bud root length and biomass were all reached to their maximum values when the concentration of Zn2+ was 10 mg/L.When the concentration of Zn2+ was higher than 100 mg/L, it inhibited the germination and growth of broccoli seeds.
