英文摘要	采用盆栽试验,探讨盐度和水渍对2月龄红树植物银叶树生长的影响。结果表明,银叶树幼苗的耐盐临界值在25‰左右,低于25‰的中低盐度,有利于其幼苗的生长和生物量累积,而高于25‰的高盐度环境,将抑制甚至威胁银叶树幼苗的生存。盐度和水渍对银叶树幼苗生长有联合影响:水渍对于高盐度下的银叶树幼苗有快速致死的作用,而对中低盐度的幼苗并未有显著影响。研究结果表明:要避免将其幼苗种植在高盐度区域,并避免在较低潮位的海滩种植。; Potted plant experiments were used to investigate the effects of salinity on growth parameters of H.littoralis seedlings.Results showed that 25‰ salinity approached the limit of salt tolerance for seedlings.Salinity below 25‰ was conductive to its growth and biomass accumulation,and salinity beyond 25‰ would inhibit its growth or even threaten its survival.Combined effects of salinity and waterlogging were also examined on these seedlings.Waterlogging rapidly resulted in seedlings' death under high salinity,but if salinity was low to mediate,there were not differences in growth rates between different salinities.The research suggested this species cannot be replanted in coastal intertidal zones with high salinity and low tide level.; 国家自然科学基金项目(41276077)
