中文摘要：

以树莓叶片为试材,分析了叶片的厚度气孔密度和表皮细胞、表皮毛、栅栏组织、海绵组织、保卫细胞等叶解剖结构,比较了不同树莓品种的抗旱性。结果表明：“凯欧”和“莎妮”的叶片最厚,“加拿大黑莓”次之,其次是“南方黑树莓”“海尔特兹”的叶片最薄;“凯欧”的上下表皮、栅栏组织均最厚,其次是“莎妮”“加拿大黑莓”和“南方黑树莓”居中,“海尔特兹”最薄;“凯欧”和“莎妮”的气孔密度均最大,“加拿大黑莓”和“南方黑树莓”居中,“海尔特兹”最小;隶属函数综合分析发现,5个树莓品种中“凯欧”的耐旱性最强,其次是“莎妮”,再次是“南方黑树莓”和“加拿大黑莓”;“海尔特兹”的耐旱性最弱。

英文摘要：

The thickness of leaf,stomata density,leaf anatomical structure of epidermal cells,palisade tissue,spongy tissue,guard cells were analyzed with raspberry leaves to compare drought resistance of five kinds of raspberry varieties.The results showed that the leaves of‘Kaiou＇（KO）and‘Shani＇（SN）were the thickest,followed by‘Canada black berry＇（CAN）and‘Southern black raspberry＇（SBR）and‘Heritage＇was the thinnest;the epidermal cells and palisade tissue of KO were the thickest,followed by SN,and CAN and SBR,while‘Heritage＇was the thinnest.The stomatal density of KO and SN were the biggest,followed by CAN and SBR,‘Heritage＇was the minimum.By membership values of anatomy-comprehensive analysis,the drought tolerance was that KO was the best and then SN,followed by CAN and SBR,while‘Heritage＇was the worst.
