Thischaracteristic of Atriplex canescens is consistent with that of many local species. TheLCP of Atriplex canescens in different treatments (light, medium, no and heavy watersoil stress) are 314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1), respectively, which indicates that the LCP of Atriplex canescens is reducingwith the escalation of soil water stress. This tendency is favorable for Atriplexcanescens under drought stress to maintain certain photosynthesis even in weaksunlight so as to ensure the survival of itself, and keep balance between maintainingwater content inside and its photosynthesis.
四翅滨藜在不同土壤水分胁迫下的光补偿点:轻度土壤水分胁迫、中度土壤水分胁迫、无土壤水分胁迫和重度土壤水分胁迫下的光补偿点分别为,314.8μmolm~(-2)s~(-1)、272.5μmolm~(-2)s~(-1)、176.7μmolm~(-2)s~(-1)、143.1μmolm~(-2)s~(-1),说明四翅滨藜的LCP随着土壤水分胁迫的加重而呈现降低的趋势,这种变化有利于处在干旱胁迫中的四翅滨藜在光强较弱的条件下仍然能维持一定的光合作用,以满足植物自身生命活动所需,同时也可以使植物在保持体内水分和进行光合作用之间寻找平衡。

In August,there are obvious changes among different treatments under soil water stressconditions. Vs, and Vs/Va obviously raised while Va reduced, and tissue water contentalso changed. Comparing with that in July, water content of leaves in differenttreatments in August decreased by 18.06%, 2.57%, 4.82% and 9.94%, respectively.In August and September, diurnal average Tr under different treatments (light,medium, heavy and no soil water stress conditions ) are 80.90 mmolh_2Om~(-2)s~(-1)、76.37mmolh_2Om~(-2)s~(-1)、65.46 mmolh_2Om~(-2)s~(-1)、42.11 mmolh_2Om~(-2)s~(-1) and 40.60mmolh_2Om~(-2)s~(-1)、33.92 mmolh_2Om~(-2)s~(-1)、30.44 mmolh_2Om~(-2)s~(-1)、23.29 mmolh_2Om~(-2)s~(-1),respectively. It shows that the Tr of Atriplex canescens leaves takes a tendency ofdeclining under long-term soil water stress conditions.
随着土壤水分胁迫时间延长到8月份,各处理间相比发生了显著变化,其中Vs、Vs/Va显著升高,Va的降低,而组织含水量也发生了显著的变化;8月份各处理间(无土壤水分胁迫、轻度土壤水分胁迫、中度土壤水分胁迫和重度水分胁迫)与7月份相比叶片含水量分别降低了18.06%、2.57%、4.82%、9.94%;在8月份和9月份轻度土壤水分胁迫、中度土壤水分胁迫、重度土壤水分胁迫和无土壤水分胁迫的Tr的日均值分别为80.90 molh_2Om~(-2)s~(-1)、76.37mmolh_2Om~(-2)s~(-1)、65.46 mmolh_2Om~(-2)s~(-1)、42.11 mmolh_2Om~(-2)s~(-1)和40.60 molh_2Om~(-2)s~(-1)、33.92 mmolh_2Om~(-2)s~(-1)、30.44 mmolh_2Om~(-2)s~(-1)、23.29 mmolh_2Om~(-2)s~(-1),说明四翅滨藜在长期的土壤水分胁迫胁迫下叶片的蒸腾速率呈现出下降的趋势。

Under soil water stress conditions, the photosynthesis rate, water useefficiency and light compensation point of Atriplex canescens obviouslyreduced, and its dark respiration rate weakened. In the treatments in July, theaccumulative and average value of daily Pn from high to low is: light soil water stress>no soil water stress>medium soil water stress>heavy soil water stress, the valueare 7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1) and 1.761μmolm~(-2)s~(-1), respectively. In the treatments in August, the accumulative and average value ofdaily Pn from high to low is: light soil water stress>medium soil water stress>heavy soil water stress>no soil water stress, the value are 7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1) and 1.705μmolm~(-2)s~(-1), respectively.
在土壤水分胁迫下四翅滨藜的净光合速率、水分利用效率、和光补偿点显著降低,暗呼吸速率减弱。7月份各处理Pn全天的累计值和平均值的大小顺序为:轻度土壤水分胁迫>无土壤水分胁迫>中度土壤水分胁迫>重度土壤水分胁迫,它们的值分别为:7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1)和1.761μmolm~(-2)s~(-1)。8月份各处理的Pn全天累计值和平均值的大小顺序为:轻度土壤水分胁迫>中度土壤水分胁迫>重度土壤水分胁迫>无土壤水分胁迫,它们的值分别为:7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1)和1.705μmolm~(-2)s~(-1)。9月份四翅滨藜的Pn变化趋势于8月份的变化曲线基本相似,唯一不同的变化就是各个处理的Pn比8月份的要高,这可能于9月份气温降低,湿度增大有关。

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。
