| 摘 要： | 采用盆栽试验研究干旱胁迫条件下5种野生护坡植物木豆(Cajanuscajan Millsp.)、山毛豆(Tephrosia candida)、多花木兰(Indigofers amblyatha Craib)、盐肤木(Rhus chinensis Mill.)以及黄荆(Vitex negundo L.)的抗旱形态、生理表现.选择叶片相对电导率、丙二醛含量(MDA)、可溶性糖含量、相对水分亏损以及离体叶片保水力作为研究抗旱适应性评价指标,在研究生理指标与抗旱性关系的基础上,采用隶属函数法对5种野生植物进行综合评价.结果表明抗旱能力为黄荆(多花木兰(盐肤木(木豆(山毛豆,这一结果与5种植物的实际表现相一致. |

| Abstract: | The drought resistance and piysiological characters under drought stress of 5 wild slope-protecting plant species(Cajanuscajan Millsp.,Tephrosia candida,Indigofers amblyatha Craib,Rhus chinensis Mill.and Vitex negundo L.) were investigated in the potted plant experiment.On the basis of the relationship between physiological standards(leaf relative conductivity,malondialdehyde(MDA),soluble sugar,relative moisture loss,water-holding capacity of detached leaves) and drought resistance,the comprehensive evaluation of the 5 wild plant species was handled by subordinative function method.The results indicated that their drought resistance in the order from strong to weak was V.negundo,I.amblyatha,R.chinensis,Cajanuscajan,T.candida,according to their practical performance. |
