[目的] 探讨干旱与半干旱区受损红砂种群幼苗适宜生长的土壤水分条件
为红砂植被保护、恢复、重建提供理论依据。[方法] 采用盆栽试验研究不同土壤水分条件下红砂幼苗生长及渗透调节物质差异。[结果] 随土壤水分胁迫程度的加剧
红砂幼苗茎叶总生物量呈明显的减少趋势
其株高呈逐渐降低的变化趋势
而根冠比、根长和根表面积均呈逐步增大的变化趋势
根系生物量呈先增加后减少的变化趋势。随土壤水分胁迫程度的加剧
红砂幼苗茎叶、根组织中脯氨酸含量均表现出明显的增加趋势
而可溶性糖和可溶性蛋白含量的变化相对不明显。[结论] 土壤水分胁迫下红砂幼苗可通过调整自身生长和生物量分配来加大根冠比以及通过积累脯氨酸来适应干旱胁迫
维持植株正常生长。
[Objective] We aimed to sort out condition of soil moisture which is fitted for the growth of Reaumuria soongorica seedlings in arid or semi-arid area
and further provide a support for the preservation and reestablishment of Reaumuria soongorica population
and for the restoration of its community.[Methods] Pot experiment was carried out to study the effects of soil water limited stress on the growth of Reaumuria soongorica seedlings and the regulation of osmotic substances.[Results] Stem and leaf biomasses of Reaumuria soongorica seedlings were significantly decreased with the increasing of soil water limited stress
and seedling height also decreased gradually. Whereas
root-shoot ratio
root length and root surface area gradually increased. Root biomass experienced a decrease at light stress
and began to increase at server stress. Proline contents of stem-leaf and root in Reaumuria soongorica seedlings significantly increased with the increasing of soil water stress. However
changes of soluble sugar and protein contents in Reaumuria soongorica seedlings were not obvious.[Conclusion] Reaumuria soongorica seedlings have its adaption ways to drought through employing seedling growth adjustment
biomass reallocation
increase of root-shoot ratio
and accumulation of proline.
