摘要: 为了解盐碱地上北美海棠叶片解剖结构差异,分析其耐盐性,以‘冬红’‘绚丽’‘王族’‘红宝石’‘喜洋洋’‘亚当’‘舞美’‘凯尔斯’8个北美海棠品种为研究对象,分析其叶片解剖结构。结果显示:‘舞美’(101.593个/mm2)的叶片气孔密度最高,‘凯尔斯’(0.112 mm2)的保卫细胞面积最大,‘亚当’(8.289 μm)的保卫细胞横径最长,‘亚当’(37.857 μm)保卫细胞的纵径最长。隶属函数综合分析显示,耐盐性上,‘凯尔斯’(0.969)最强,‘亚当’(0.789)、‘冬红’(0.688)和‘王族’(0.606)较强,‘绚丽’(0.543)、‘喜洋洋’(0.498)和‘红宝石’(0.413)较差,‘舞美’(0.064)最差。

Abstract: In order to understand the difference of leaf anatomical structure and its salt tolerance on the saline-alkali land, leaf anatomical structures of North American crabapple varieties such as ‘Donghong’, ‘Wumei’, ‘Adam’, ‘Xiyangyang’ ‘Guandian’ ‘Royal’ ‘Kells’and ‘Ruby’were analyzed. The results showed that the highest stomatal density was on the blade of ‘Wumei’(101.593 pieces/mm2); the guard cell area of Kells(0.112 mm2)was the largest; the guard cell transverse diameter of ‘Adam’(8.289 μm)was the longest; the guard cell longitudinal diameter of ‘Adam’(37.857 μm)was the longest; ‘Guardian’(0.4)had the highest aspect ratio of guard cells. The salt-tolerance of ‘Kells’(0.969)was the strongest, followed by ‘Adam’(0.789), ‘Donghong’(0.688), ‘Royal’(0.606), ‘Guardian’(0.543), ‘Xiyangyang’(0.498), ‘Ruby’(0.413)and ‘Wumei’(0.064)according to comprehensive analysis of membership functions.
