摘要为提高天津滨海盐碱地区生态修复植被层次，引种适宜天津滨海盐碱地区的绿化树木，对华北地区常用6种绿化树木（合欢、木槿、紫穗槐、宁夏枸杞、金银忍冬和爬山虎）的抗盐调节规律及其耐盐性进行探索，模拟设计0.2%~0.5%共4个NaCl溶液质量分数梯度进行处理，测算不同浓度盐胁迫下各树木的存活率、生物量、相对电导率、丙二醛和可溶性糖含量，并采用隶属函数法综合评价6种树木的耐盐性。结果表明：各树木在盐胁迫下生物量整体呈下降趋势，且随盐浓度的升高而生长受抑制程度加剧，宁夏枸杞生长对盐胁迫最敏感；0.2%和0.3%质量分数盐胁迫可刺激紫穗槐地上部分的生长以增加其生物量，木槿耐盐生物量分配策略与其相反；各树木随盐胁迫浓度的升高相对电导率和丙二醛含量增加，其中紫穗槐和合欢表现出更为稳定的细胞膜结构与功能；各树木可溶性糖质量分数整体呈上升趋势，爬山虎在>0.3%质量分数盐胁迫下可溶性糖的渗透调节功能紊乱，细胞膜透性增加，幼苗存活率大幅度降低。6种绿化树木幼苗综合耐盐性表现为紫穗槐 > 合欢 > 木槿 > 金银忍冬 > 宁夏枸杞 > 爬山虎。

Abstract：[Background] Tianjin Binhai New district is the first national comprehensive reform and innovation zone in China, but its land is severely salinized. This problem restricts its saline-alkali land reclamation and ecological restoration, resulting in serious soil erosion problems, which is not conducive to its sustainable economic,social and ecological development. Therefore, based on the soil and plant conditions in the coastal saline-alkali area of Tianjin, this study selected 6 representative greening trees in North China to explore their physiological salt tolerance mechanisms and to conduct a comprehensive salt tolerance evaluation. This study aims to add alternative greening trees to the saline-alkali area of Tianjin Binhai New district, and to improve the level of green landscape in the process of ecological restoration in this area.[Methods] Six greening tree seedlings (Albizia julibrissin, Hibiscus syriacus,Amorpha fruticosa, Lycium barbarum,Lonicera maackii, and Parthenocissus tricuspidata) commonly used in North China were selected as test materials, and a gradient design of 4 NaCl solution concentrations of 0.2%-0.5% was simulated to calculate the growth and physiological indexes of different tree seedlings under salt stress, and the membership function method was adpated for the comprehensive evaluation of the salt tolerance of 6 tree seedlings.[Results] 1) A. fruticosa, H. syriacus and A. julibrissin were all alive after 15 d of salt stress at each concentration. L. barbarum, L. maackii and P. tricuspidata were alive with the increase of concentration and the number of cultivation days, their survival rates decreased, and P. tricuspidata cultivated at 0.5% concentration all died after 15 d. 2) With the increase of salt concentration, the biomass of A. fruticosa increased firstly and then decreased, and the biomass of other trees decreased. Under the 0.2% and 0.3% concentration, the aboveground biomass of A. fruticosa increased, and the belowground biomass of H. syriacus increased. 3) Under salt stress, the relative conductivity, MDA and soluble sugar content of the 6 tree seedling leaves increased. The soluble sugar content of L. maackii changed the most. The soluble sugar content of P. tricuspidata vulgaris reached the peak at 0.3% and then decreased.[Conclusions] The growth of L. barbarum is the most sensitive to salt stress, and the growth of A. fruticosa is promoted under 0.2% and 0.3% salt stress. The aboveground part of H. syriacus is more sensitive to salt stress, and the underground part of A. fruticosa is more sensitive to salt stress. A. fruticosa and A. julibrissin showed a more stable cell membrane structure and function under salt stress. P. tricuspidata had a disordered osmotic regulation function of soluble sugar from 0.3% salt stress, and the cell membrane structure was severely damaged.The comprehensive salt tolerance of 6 greening tree seedlings was A. fruticosan > H. syriacus > A. julibrissi > L. barbarum > L. maacki > P. tricuspidata.
