摘要:
 为探究杨树抗旱性的机理,采用石蜡切片法对11个美洲黑杨无性系进行叶片解剖结构观测。通过隶属函数法和灰色关联度法对其叶片厚度、中脉厚度、上表皮厚度、下表皮厚度、上层栅栏组织厚度、下层栅栏组织厚度、CTR等7项指标进行抗旱性综合评价及其相关性分析。结果表明,11个美洲黑杨无性系抗旱性大小依次为:南抗杨>美洲黑杨2号>美洲黑杨3号>08H4-5>08H2-16>03S4-1>69杨>08H11-11>美洲黑杨1号>陕林3号>08H1-6。此外,上下层栅栏组织厚度、叶片厚度等指标与美洲黑杨无性系的抗旱性关联度最高。该研究可为美洲黑杨无性系的遗传育种和高效培育提供科学依据。
Abstract:
 In order to explore the mechanism of drought resistance of poplar,the leaf anatomical structures of 11 poplar clones were observed by paraffin section method.Through the membership function method and grey relational degree method in fuzzy mathematics,the drought resistance of 7 indicators were comprehensively evaluated and correlated,including the thicknesses of leaf,midrib,upper epidermis thickness,lower epidermis,upper palisade tissue,lower palisade tissue,and tightness of leaf tissue structure (CTR).The results showed that the order of drought resistance of 11 Populus deltoides clones was ‘NanKang’ poplar>P.deltoides No.2>P.deltoides No.3>08H4-5>08H2-16>03S4-1>69 poplar>08H11-11>P.deltoides No.1>Shanlin No.3>08H1-6.In addition,the thicknesses of upper and lower palisade tissue,leaf thickness and other indicators had the highest correlation with drought resistance of P.deltoides clones,which would provide scientific basis for genetic breeding and efficient breeding of P.deltoides clones.
