摘要: 为了解盐碱地上北美海棠叶柄解剖结构差异,分析其耐盐性和耐旱性,本文以‘冬红’‘舞美’‘亚当’‘喜洋洋’等8个北美海棠品种为研究对象,分析其解剖结构。结果显示:‘绚丽’(7.57 μm)叶柄的角质层最厚,‘舞美’(5.12 μm)的最薄;‘亚当’(426.05 μm)叶柄的韧皮部厚度最大,‘红宝石’(312.47 μm)的最小;‘亚当’(416.28 μm)叶柄的木质部最大,‘红宝石’(267.00 μm)的最小;‘冬红’(415.10个)的木质部导管个数最多,‘舞美’(333.45个)的最小。隶属函数综合分析显示,耐旱耐盐性方面‘亚当’(0.784 μm)‘绚丽’(0.757 μm)‘冬红’(0.721 μm)最强;‘凯尔斯’(0.650 μm)其次,‘王族’(0.371 μm)和‘喜洋洋’(0.328 μm)较差;‘舞美’(0.078 μm)和‘红宝石’(0.025 μm)最差。

Abstract: In order to understand the difference of petiole anatomical structure of north American crabapple and its salt and drought tolerance on the saline-alkali land, north American crabapple varieties such as ‘Donghong’‘Wumei’‘Adam’ and ‘Xiyangyang’ were used as research objects to analyze their anatomical structures. The results showed that the petiole of ‘Xuan li’(7.57 μm)was the thickest in the cuticle, and ‘Wumei’ the thinnest(5.12 μm); the phloem thickness of the petiole of ‘Adam’(426.05 μm)was the largest, and that of ruby(312.47 μm)was the smallest; .The xylem of ‘Adam’(416.28 μm)was the largest and ‘Ruby’(267.00 μm)was the smallest; ‘Donghong’(415.10)had the largest number of xylem and ‘Wumei’(333.45)had the smallest. Comprehensive analysis of membership functions showedthat the drought-tolerance and salt-tolerance upper Adam(0.784 μm)‘Xuanli’(0.757 μm)and Dongahong(0.721 μm)were the strongest, followed by ‘Kells’(0.650 μm), ‘Royal’(0.371 μm)and ‘Xiyangyang’(0.328 μm); ‘Wumei’(0.078 μm)and ‘Ruby’(0.025 μm)were the worst.

Key words: salt tolerance, drought tolerance, North American crabapple, varieties, petiole anatomical structure
