| 摘 要： | 通过盆栽试验,研究了废旧电池在2种处理方式不同浓度下胁迫对香根草的细胞膜透性、脯氨酸(Pro)含量、叶绿素(Chl)含量、光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs)等的影响。结果表明,随稀释液浓度、内含物量增加,香根草叶片生长速率、Chl含量、Pn、Tr和Gs虽呈下降趋势,而Pro含量有所升高,膜透性增大,但不同稀释液和内容物填埋处理对香根草的胁迫毒害作用差异不明显,在稀释液浓度为14.44%或以下和内容物占土壤2.70%或以下时,香根草能生长,在稀释液浓度为20.20%或以上和内容物占土壤4.00%或以上时,香根草均死亡。

| Abstract: | The influence on the cell membrane,proline content(Pro),chlorophyll content(Chl),photosynthetic rate(Pn),transpiration rate(Tr)and stomatal conductance(Gs)of Vetiveria zizanioides from two different used batteries stress treatments were studied by pot experiment.The results showed that as the amount of direct landfill and the concentration of content dilution of used batteries increased,the leaf growth rate,Chl content,Pn,Tr and Gs of V.zizanioides declined,and Pro content,membrane permeability increased.Th... |
