中文摘要	异子蓬是一年生盐生植物,能产生两种类型的种子。前人研究表明,异子蓬异型种子具有不同的萌发耐盐性,而异型种子在长成植株后,其生长后期的耐盐性无显著差异。因此,假设异型种子植株在生长中期可能会有不同耐盐性。该实验分析了不同盐分水平对异子蓬异型种子植株生物量和矿质营养元素含量的影响。结果表明:异子蓬异型种子植株在生物量和大部分生理指标上不存在显著差异。盐分对异子蓬生长的影响表现为低、中盐促进,高盐抑制。Na~+和Cl~-含量随盐分浓度的增加而增加。总之,异子蓬异型种子生长中期的植株具有相似的耐盐性,耐盐差异可能出现在生长早期。
英文摘要	Suaeda aralocaspica,an annual halophyte growing in the deserts in Central Asia,produces two distinct types of seeds that differ in shape,color,dormancy and germination. Brown and black seeds of S. aralocaspica have different salt tolerance during germination. However, there was no significant difference in salt tolerance of S. aralocaspica plants grown from dimorphic seeds at late growth stage. The possibility that plants grown from dimorphic seeds at middle growth stage may differ in salt tolerance was not investigated previously. Experiments were designed to investigate the growth and mineral nutrient concentrations of plants grown from dimorphic seeds of S. aralocaspica under different salinity levels. There was no significant difference between plants grown from dimorphic seeds with respect to growth and most physiological parameters. Low to medium salinity promotes the plant growth,but high salinity inhibits the plant growth. The biomass of S. aralocaspica plants growing under medium salinity was the highest. Concentrations of Na~+ and Cl~- were increased with the increase of supplied salinity. This indicated that S. aralocaspica plants require a certain amount of salinity to maintain osmotic homeostasis. In conclusion, the salt tolerance of the plants grown from dimorphic seeds of S. aralocaspica at middle growth stage was similar. The carryover of differential salt tolerance in plants grown from dimorphic seeds may display at the early stage of plant growth.
