- 摘要:
- 以八宝景天、沙打旺、紫花苜蓿和早熟禾4种典型干旱区草本植物为试材，采用盆栽控水法进行干旱胁迫，测定了4种植物叶片相对含水量、相对电导率、叶绿素含量、脯氨酸(Pro)含量、丙二醛(MDA)含量和可溶性糖含量6个抗旱指标的变化；运用隶属函数值法进行植物抗旱性综合评价，并采用灰色关联度法对6项抗旱指标与植物抗旱性的关联度进行分析，以研究不同植物在干旱胁迫下的抗旱机制。结果表明：4种植物综合抗旱性顺序为：八宝景天>早熟禾>紫花苜蓿>沙打旺；各项抗旱指标与植物抗旱隶属函数均值关联度大小顺序为：叶绿素含量(0.9727)、叶片相对含水量(0.9387)、可溶性糖含量(0.8314)、丙二醛含量(0.7940)、相对电导率(0.6320)、脯氨酸含量(0.4528)，即叶绿素含量、叶片相对含水量和可溶性糖含量对干旱环境最为敏感，可作为矿区生态修复抗旱植物筛选的重要评价指标。
- Abstract:
- In order to research the mechanism of drought resistance of different plants under drought stress,4 kinds of plant species that typical in the ecological regeneration on arid region,including Sedum spectabile Boreau, Astragalus adsurgens Pall,Medicago sativa L. and Poa annua L. were selected,and changes of 6 drought resistance indexes including the relative water content,relative conductivity,chlorophyll content,contents of proline,malondialdehyde and soluble carbohydrate were measured with potted controlled water.Then the fuzzy membership function analysis to integrated evaluate plant drought resistance were used,and the grey correlation analysis to analyze the association between 6 drought indicators and plant drought resistance were adopted.The results showed that,the drought resistant capability of 4 arid region plants was in order of Sedum spectabile Boreau>Poa annua L.>Medicago sativa L.>Astragalus adsurgens Pall,and the relational degree order about each index of drought resistance and average subordinate function values was：chlorophyll content (0.9727),relative water content (0.9387),soluble carbohydrate (0.8314),malondialdehyde content (0.7940),relative conductivity (0.6320),content of proline (0.4528).So,chlorophyll content,relative water content and soluble carbohydrate were the most sensitive indexes to drought environment and can be accepted as the indexes of evaluating and selecting the drought resistant plant species for ecological regeneration on mining area.
