| 摘 要： | 以4种美国紫菀(Aster novae-angliae)品种1年生扦插苗为研究材料,采用盆栽控水的方法,研究了水分胁迫下4个紫菀品种生理生化变化。结果表明,随着干旱胁迫程度增加,不同紫菀品种叶水势呈降低趋势,降低幅度依次为粉花>安德>紫球>香叶;相对电导率的含量则明显增加,依次为紫球>安德>香叶>粉花;丙二醛(MDA)的含量则显著增加,依次为紫球>香叶>安德>粉花;超氧化物歧化酶(SOD)与过氧化物酶(POD)活性变化,则分别呈现单峰型与双峰型曲线,2种保护酶含量依次均为粉花>安德>香叶>紫球。利用Fuzzy隶属函数法,对4个紫菀品种基于以上5项指标的抗旱性进行了综合评价,得出其抗旱性强弱排序为:粉花>安德>香叶>紫球。

| Abstract: | With one-year-old cuttings as test materials,this paper studied the physiological characteristics of four varieties of Aster novae-angliae under drought stress by means of pot experiment.The results indicated that with the increase of drought stress,the leaf water potential of different varieties decreased and in the order of Barr's Pink > Andenken an Alma Potschke >Purple Dome> Herbstschnee.The cell membrane permeation increased obviously and was in the order of Purple Dome > Andenken an Alma Potschke > He... |
