摘    要:研究了黑麦草和菊苣种子萌发以及幼苗生理指标的变化。实验结果表明,牧草种子萌发主要取决于自养条件,受镉影响不大。外源添加镉会对幼苗生物量、苗长、叶绿素和根系活力产生影响。镉浓度增加,表现出先增后降的趋势。当镉浓度为20mg/L时,两种牧草的生长受到抑制,差异极显著(p≤0.01)。

关 键 词:  幼苗  黑麦草  菊苣

Abstract:The experiment is conducted on the germination and some physiological indices of ryegrass (Lolium perenne L.) and chicory (Cichorium intybus L.) under the stress of cadmium.The results indicate there is no significant discrepancy in germinability of the two herbage breeds,because their germination is mainly depen- ded on self-nutrition,not on cadmium.The two herbage seedling growth including the content of chlorophyll, protein,root vitality,biomass and plant height,are affected under the stress of cadmium concentration.And the trend is up first,then down when the concentration of cadmium is increased.The two herbage seedling growth is restrained by 20 mg/L cadmium,and the significance lever is 0.01.
Keywords:cadmium  seedling  lolium perenne L    Cichorium intybus L
