摘要: 为筛选广义菊属内的优良抗旱种质,本研究对中国中部和北部地区的内蒙古、河北、河南、安徽、湖北、湖南、山东和福建省等地进行调查,收集了16种广义菊属资源。根据其生境及适应情况,以太行菊、线叶菊、灌木亚菊、野菊、蒙菊、甘菊等6个广义菊属野生种为实验材料,采用盆栽控水法,测定干旱胁迫(土壤含水量30%~35%)前后叶片的光合指标以及生理指标,并用隶属函数法对不同菊属种的抗旱性进行综合评价,以期筛选出广义菊属中的优质抗旱种质。结果表明,干旱胁迫后,6个野生种的叶片光合指标与生理指标均呈现不同程度的变化,隶属函数法综合评价其抗旱能力从强到弱依次为:太行菊、线叶菊、灌木亚菊、野菊、蒙菊、甘菊。

Abstract: In order to screen drought resistant germplasms of Chrysanthemum and related genera, we investigated and collected sixteen species of germplasm of Chrysanthemum and related sources in north and central China including Inner Mongolia, Hebei, Henan, Anhui, Hubei, Hunan, Shandong and Fujian provinces. According to their wild habitats and adaptation, in this study, photosynthetic characteristics and physiological indexes of leaves under drought stress (soil water content of 30%-35%) were measured by pot experiment in six species including Opisthopappus taihangensis, Filifolium sibiricum, Ajania fruticulosa, Chrysanthemum indicum, Chrysanthemum mongolicum, Chrysanthemum lavandulifolium. And the drought resistance of different species was evaluated by membership function method in order to screen out the germplasms with good quality and high drought resistance. The results showed that the photosynthetic and physiological indexes of the six wild species showed different degrees after drought stress, and the membership function method was used to evaluate the drought resistance from strong to weak followed by: Opisthopappus taihangensis, Filifolium sibiricum, Ajania fruticulosaLedeb, Chrysanthemum lavandulifolium, Chrysanthemum mongolicum, Chrysanthemum indicum.
