以渤海湾津唐沿海地带895份野生大豆种群在高盐碱(3%)环境下的全生育期鉴定试验,分析不同种群(株系)的生长发育动态以及对盐碱土壤生态适应性的分化.结果表明,出苗阶段存在3种耐盐碱能力类型:耐高盐碱胁迫发芽出苗;耐低盐碱胁迫发芽出苗;盐胁迫不能发芽出苗.在高盐胁迫下营养生长早期阶段种群死亡率最高,中期以后相对降低,成熟期死亡率较低.种群植株形态建成和生殖生长受到高盐胁迫的强烈抑制,表现早期严重而后期较轻.植株和产量性状的受害程度由大到小依次为:单株的地上千物质重、单株产量、种子数、百粒重和收获指数.株系间变异系数从大到小依次为:单株产量、种子数、荚数、收获指数、地上干物质重、百粒重.研究揭示该地域种群内对盐碱土壤有很高的适应性分化,存在高耐盐碱生态型.

The exploitation of crops with salinity tolerance is significant for the agriculture.Total 895 individual plants of wild soybean were collected from the littoral population in the Bohai Bay region bestriding Tianjin and Tangshan areas.The tolerance identification was carried out with three experimental treatments.The results showed that there were a series of salinity tolerant individual lines of different intensities at various growth phases in the Jin-Tang population,suggesting that edaphic ecotypic differentiation existed in this population.At seed germination,there were three kinds of lines for germination ability:germinable(high-tolerant);germinable at a reduced level of salinity stress;incapable(sensitive).The growth of plants at earlier stage was worse inhibited than subsequent stages.The damaged degrees of morphological traits in the population showed as the order:overground dry weight,yield,seed number per plant,100-seed weight,and harvesting index.The coefficients of variation in traits between lines was ordinal yield,seed number,pod number,harvesting index,overground dry weight per plant,and 100-seed weight.The Jin-Tang population had high levels of edaphic ecological adaptation and edaphic ecotype with high levels of salinity tolerance,which was expected to become useful in developing high salinity-tolerant soybeans.
