| 摘 要： | 采用盆栽法选择土壤含水量作为干旱胁迫的定量评价标准,叶片相对含水量及水分饱和亏缺、质膜相对透性、净光合速率(Pn)、气孔导度(Cond)、胞间CO2浓度(Ci)和蒸腾速率(Tr)等作为研究抗旱适应性的评价指标,研究干旱胁迫下麻疯树(Jatropha curcas L)、坡柳(Dodonaea viscose)、木豆(Cajanus cajan Millsp)、山毛豆(Tephrosia candida)的生理表现及光合特性。结果表明,干旱胁迫后,4种植物的叶片相对含水量下降,质膜相对透性增大,光合作用受到影响。综合各项指标及运用隶属函数分析得出4种植物的抗旱性依次为麻疯树坡柳木豆山毛豆。 |

| Abstract: | By pot experiment,the physiological adaptabilities and photosynthetic characteristic of Jatropha curcas L,Dodonaea viscose,Cajanus cajan Millsp and Tephrosia candida were studied under drought stress with the soil water content as the quatitative evaluation standard,leaf relative water content and water deficit,leaf relative conductivity,net photosynthetic rate(Pn),intercellular CO2concentration(Ci),stomatal conductance(Cond) and transpiration rate(Tr) as evaluation indices.The results showed that the leaf ... |
