中文摘要	为了探明文冠果(Xanthoceras sorbifolium)不同种质资源叶片气孔特征之间的差异,了解文冠果气孔对干旱环境下的生理生态响应,以内蒙古自治区鄂尔多斯市鄂托克前旗的108份文冠果种质资源叶片为研究对象,在测定其气孔长度、气孔孔隙长轴长度、气孔宽度、气孔密度和气孔面积指数等12项指标的基础上,利用主成分分析法、隶属函数值法和聚类分析法进行抗旱性鉴定,筛选出适合在干旱地区种植的种质资源,为文冠果在我国干旱和半干旱地区的种植提供参考。结果表明:气孔面积与气孔长、气孔空隙长轴长、气孔宽、气孔周长、气孔开口周长、气孔面积占叶面积比例、气孔面积指数和气孔开口面积指数存在极显著相关。主成分分析将12个性状归纳为3个主成分(累计贡献率为93.408%),第I主成分载荷主要是气孔密度,第Ⅱ主成分载荷主要是气孔开口面积指数,第Ⅲ主成分载荷主要是气孔面积指数。将108份文冠果种质资源聚为3种类型,其中31份抗旱节水类型种质资源适合在干旱地区种植。气孔密度、气孔开口面积指数和气孔面积指数可作为文冠果种质资源抗旱性评价的有效指标。
英文摘要	In order to study the differences in the leaf stomata characteristics of yellowhorn (Xanthoceras sorbifolium)with different germplasm resources and to understand the physiological and ecological response of yellowhorn leave stomata structure to drought stress, We used 108 yellowhorn trees from Erdos City, Inner Mongolia Autonomous Region, China as the research object.The 12 indicators including stomatal length, length of stomatal gap long axial, stomatal width, stomatal density, stomatal area index and so on were measured.We used the principal component analysis (PCA),subordinate function values and cluster analysis to identify the drought resistance, and screen out germplasm resources which were suitable for planting in arid areas.This study can provide a reference for the cultivation of the yellowhorn in arid and semi-arid areas in China.The results showed that stomatal area was significantly correlated with stomatal length, long axial length of stomata, stomatal width, stomatal perimeter, stomatal opening perimeter, the proportion of stomatal area to leaf area, stomatal area index and stomatal opening area index.Using principal component analysis to 12 characters summarized as three principal components (the cumulative contribution rate is 93.408%), the first principal component load mainly was stomatal density, the second principal component load mainly was stomatal opening area index, and the last principal component load mainly was stomatal area index.The 108 germplasm resources were clustered into three types, one of the types was drought-resistant and water-conserving which included 31 germplasm resources were suitable for planting in arid areas.The stomatal density, stomatal open area index and stomatal area index can be used as the effective indexes for evaluating drought resistance of germplasm resources of yellowhorn.
