摘要: 为研究不同北美海棠品种在轻度盐碱土上的生长特性,以北美海棠品种中的‘冬红’‘舞美’‘亚当’‘喜洋洋’‘绚丽’‘凯尔斯’‘王族’‘红宝石’为研究对象,研究了其不同年份的年轮生长动态。结果显示:盐碱地上8个北美海棠品种6年平均的年轮增长量为‘冬红’(0.633 cm)最高,‘王族’(0.464 cm)最低;从不同年份的年轮生长动态来看,各品种2015年(0.739 cm)的平均年轮生长量最高,相比2011年(0.260 cm)增长了183.85%。从各年年轮的变化幅度看,‘冬红’‘舞美’‘绚丽’和‘红宝石’变幅较小,‘凯尔斯’‘亚当’‘喜洋洋’和‘王族’波动较大。综合分析认为,‘冬红’更适应轻度盐碱地种植。

Abstract: :In order to study the growth of theNorth American crabapple on mild saline soil, the growth dynamics of annual rings in different yearswere studied with ‘Donghong’ ‘Wumei’ ‘Yadang’ ‘Xiyangyang’ ‘Xuanli’ ‘Kiles’ ‘Royal’ ‘Ruby’.The results showed that the annual average growth rings of ‘Dong Hong’(0.633 cm)was the highest, and the ‘Royal’(0.464 cm)was the lowest. From the growth dynamics of annual growth rings in different years, the average annual growth volume(0.739 cm)in all cultivars in 2015 was the highest, which was increased by 183.85% compared to 2011(0.260 cm). From the magnitude changes of annual rings in each year, the variation of ‘Donghong’ ‘Wumei’ ‘Xuanli’ and ‘Ruby’ were smaller, while ‘Kiles’ ‘Yadang’ ‘XiYangyang’ and ‘Royal’ had greater fluctuations. Therefore, the comprehensive analysis suggested that ‘DongHong’ was more suitable for the cultivation of mild saline soil.
