摘要: 【目的】测定不同种源地酸枣植株根蘖苗,在相同盐碱条件下的表现和内在指标,综合评价不同酸枣植株根蘖苗的耐盐碱性,为新疆南疆地区红枣耐盐碱砧木的选育和推广提供参考。【方法】筛选出的10份优良酸枣品系,经过根蘖繁殖后的150株酸枣幼苗为试材,用浓度为0.6%的混合盐碱液浇灌30 d,观察在混合盐碱液胁迫下不同品系酸枣根蘖苗外观表现,测定其叶片叶绿素和渗透调节物质含量。【结果】混合盐碱胁迫下,不同酸枣根蘖苗的外观指标中苗高、根长、单株鲜重以及叶片生理等差异明显,茎粗无显著差异;不同酸枣根蘖苗在同一浓度混合盐碱液浇灌处理下叶片叶绿素含量、可溶性总糖含量、可溶性蛋白含量、MDA含量之间存在显著差异,Pro含量无显著差异。【结论】根据隶属函数综合评价结果对不同品系酸枣根蘖苗进行排序,耐盐碱性由强到弱顺序为S10>S9>S1>S3>S6,筛选出根蘖苗S10为最耐盐碱材料,可将其母株无性繁殖扩繁进行推广应用。

Abstract: 【Objective】 This paper aims to comprehensively evaluate the salt-alkali tolerance of root tiller seedlings of different jujube plants under the same saline-alkali conditions in the hope of providing reference value for breeding and popularizing saline-alkali tolerant rootstocks of red jujube in southern Xinjiang.【Method】A total of 150 jujube seedlings which had been bred by root tillering were used as test materials, and were irrigated with mixed saline-alkali solution with concentration of 0.6% for 30 days to observe the appearance of root tiller seedling of different strains of jujube under mixed saline-alkali solution stress, and to determine the content of chlorophyll and osmotic regulator in leaves of different strains of jujube.【Result】Under mixed saline-alkali stress, there were significant differences in seedling height, root length, fresh weight per plant and leaf physiology, but there was no significant difference in stem diameter. There was no significant difference in leaf chlorophyll content, soluble sugar content, soluble protein content and MDA content between tiller seedling of different jujube roots and mixed saline-alkali solution of the same concentration. There was no significant difference between the content of Pro and the content of chlorophyll, soluble sugar and soluble protein.【Conclusion】According to the comprehensive evaluation results of membership function, the jujube root tillers of different strains were sorted, the order of salt-alkaline resistance was S10 > S9 > S1 > S3 > S6, and S10 was the most salt-tolerant material, so its mother plant can be propagated through asexual propagation and promoted.

Key words: root tillers of wild jujube; salt-tolerant; root stock; screening
