旱生植物

In previous study,the ability of plant resist-drought almost focuses on plant foot,corm and leaf,except seed, especially,large number kinds of plant species is not report.

以往的植物抗旱性研究，多集中在植物成株后的根、茎、叶组织等方面，而对种子的抗旱性研究较少，特别是对批量旱生植物种子，在各种水分条件下的响应方式的研究未见报道。

Arizona is best known for its desert landscape, which is rich in xerophyte plants such as cactus.

First of all,we tested the germination and water uptake rate of 47 species typical xerophil seeds grow up in north China from 20 families,38 genuses under sufficient water and different Grads water stress by high-molecular-weight polyethylene glycol(PEG6000).The results show that Xerophil seeds from the same habitat exhibited similar patterns in response to water stress.Xerophil seeds from arid community were stronger in germination and imbibition than that from other two communities under serious water stress,whereas Xerophil seeds from humid community were sensitive to any degree of water stress.Namely,the seeds live in arid habitat possessed high germination and quickly water uptake in sufficient water or any degree of water stress,but the others grow up in humid habitat shown significant difference which germination and water uptake well under sufficient water but inhibited even if slight water stress.

首先，我们通过对20个科，38属，47种旱生植物种子在水分充足和不同梯度的干旱处理(聚乙二醇PEG6000)条件下的萌发率及吸水率实验发现，当水分胁迫强烈时，分布于干旱沙漠地区的植物种子其吸水率和萌发率都高于半干旱和湿润地区的植物群落，相反，湿润地区植物种子的吸水率和萌发率对任何的水分胁迫都表现出敏感的响应趋势，也就是说，生境恶劣的植物种子在较强的干旱胁迫下，仍然保持了较高较快的萌发率及吸水率，水分充足与水分缺乏时无显著差异，而生境相对较好的植物种子在水分充足情况下萌发与吸水良好，但在干旱胁迫时则受到明显抑制，水分充足与水分缺乏时差异显著。

It will become on the basis of theory that the forest of xerophilous arbor and shrub will expanded using the limited sources of water in the aird zone.

查明此现象，将有助于进一步认识旱生植物与其生存环境关系的多样性，从而为干旱区利用有限的水源以扩展旱生乔灌林木提供有价值的理论依据。

The leakage of K+, the peroxidation of lipids and the disruption of membranes induced by NaCl were different between halophytes and xerophyte.

NaCl诱导盐生植物和旱生植物种子K~+外渗、膜完整性破坏和膜脂过氧化反应表现不同。

The effect of NaCl on seed germination was due to both osmotic stress and ion toxicity for both halophytes, e.g., Suaeda physophora and Haloxylon ammodendron, and xerophyte, e.g., Haloxylon persicum.

NaCl对盐生植物(梭梭Haloxylon ammodendron；囊果碱蓬Suaeda physophora)和旱生植物(白梭梭Haloxylon persicum)种子萌发既有离子伤害又有渗透胁迫。
