中文摘要	在盆栽条件下,研究保水剂对梭梭(Haloxylon ammodendron)、白梭梭(Haloxylon persicum)种子萌发和幼苗根系形态的影响。结果表明:0.05%浓度的保水剂对梭梭、白梭梭种子萌发有明显的促进作用,发芽率较对照分别提高了18.7%和24.0%;0.05%浓度的保水剂能够抑制梭梭幼苗根系的垂直生长,有效促进侧根数量的增加和根系生物量的积累;0.1%浓度保水剂处理下,白梭梭的主根长度、侧根数量、根系生物量均达到最大;保水剂浓度达到0.2%时,梭梭、白梭梭种子萌发和幼苗根系的生长均受到抑制,表明梭梭幼苗生长最适宜的保水剂浓度为0.05%,白梭梭的浓度以0.05%~0.1%为宜。
英文摘要	Effect of super absorbent polymer(SAP) on the seed germination and seedling root morphology of Haloxylon ammodendron and H.persicum was investigated based on a pot experiment.The results showed that,compared with the contrast,the seed germination rates of H.ammodendron and H.persicum were increased by 18.7% and 24.0% respectively when SAP concentration was 0.05%.Vertical growth of seedling roots of H.ammodendron was inhibited,while the growth and biomass accumulation of lateral roots were promoted when SAP concentration was 0.05%.Root length,lateral root number and root biomass of H.persicum all reached their maximum values at 0.1% SAP concentration.Seed germination and seedling root growth were all inhibited when SAP concentration was 0.2%.It was concluded that the perfect SAP concentration for H.ammodendron growth was 0.05%,and the best effect of SAP concentration for H.persicum varied in a range of 0.05%-0.1%.
