doi:10.7522/j.issn.1000-694X.2019.00069

摘要/Abstract

摘要： 以甘肃10个野生马蔺（Iris lacteal var. chinensis）为材料，采用盆栽控水试验，研究了干旱胁迫对马蔺苗期生理特性的影响，运用聚类分析法对10个野生马蔺种质进行聚类，分析了抗旱性与原生境年降雨量的关系，以期为马蔺新品种选育及推广提供理论依据。结果表明：随干旱胁迫程度的加剧，10个野生马蔺种质叶片相对含水量呈下降趋势，叶片质膜相对透性、丙二醛（MDA）含量、脯氨酸（Pro）含量、可溶性糖（SS）含量、可溶性蛋白（SP）含量、超氧化物歧化酶（SOD）活性、过氧化物酶（POD）活性、过氧化氢酶（CAT）活性、过氧化氢（H₂O₂）含量、超氧自由基（O₂^-·）产生速率、羟自由基（OH^·）含量均呈上升趋势。聚类分析显示，肃州、甘州、榆中、环县、凉州马蔺抗旱性较强，民乐、临夏、天祝马蔺抗旱性中等，渭源、灵台马蔺抗旱性较弱。抗旱性与原生境年均降雨量显著负相关（P<0.05）。

Abstract: To investigate the effect of drought stress on the physiological characteristics of wild Iris lacteal var. chinensis, ten varieties of wild Iris lacteal var. chinensis from Gansu Province were selected under pot culture experiments. The drought tolerance of these varieties were evaluated after using clustering analysis. Regression analysis was used to assess the relationship between drought tolerance of these varieties and local precipitation of their original habitats. These finds can provide insight into wild Iris lacteal var. chinensis breeding and cultivation. The relative water content of ten varieties leaves decreased as drought stress increased. The permeability of cell membranes, malondialdehyde content, proline content, soluble sugar content, soluble protein content, superoxide dismutase activity, peroxidase activity, catalase activity, hydrogen peroxide (H₂O₂) content, superoxide radical (O₂^-·) generation rate, hydroxyl radical (OH^·) content of ten varieties leaves increased as drought stress increased. The wild Iris lacteal var. chinensis from Suzhou district,Ganzhou district,Yuzhong county, Huanxian county and Liangzhou district belong to high drought tolerance varieties, and the wild Iris lacteal var. chinensis from Minle county, Tianzhu county and Lingxia county belong to medium drought tolerance varieties and from Weiyuan county and Lingtai county belong to low drought tolerance cultivar. A negative significant correlation (P<0.05) was found between drought tolerance of these varieties and local precipitation of their original habitats.
