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。

DPR of Atriplex canescens in differenttreatments are quite different, 2.87μmolm~(-2)s~(-1) under no soil water stress, 6.46μmolm~(-2)s~(-1) under light soil water stress, 6.06μmolm~(-2)s~(-1) under medium soil waterstress, 3.04μmolm~(-2)s~(-1) under heavy soil water stress. Comparing with the DPRunder light soil water stress, DPR decreased by 6.19% under medium soil waterstress, by 52.94% under heavy soil water stress and by 55.57% under no soil waterstress.

不同土壤水分胁迫下四翅滨藜的DRR表现出显著的差异，无土壤水分胁迫下DRR为2.87μmolm~(-2)s~(-1)，轻度土壤水分胁迫的DRR为6.46μmolm~(-2)s~(-1)，中度土壤水分胁迫的DRR为6.06μmolm~(-2)s~(-1)，重度土壤水分胁迫的DRR为3.04μmolm~(-2)s~(-1)，以轻度土壤水分胁迫为基础中度土壤水分胁迫下降了6.19％、重度土壤水分胁迫下降了52.94％、无土壤水分胁迫下降了55.57％。

Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.

结果显示：(1)随着干旱胁迫程度的增加，2种杨树溃疡病害发生渐趋严重；(2)干旱胁迫下，杨树树皮组织细胞发生质壁分离，并随胁迫程度的增加而严重；(3)干旱胁迫下接种病原菌，2种杨树细胞发生不同程度的损伤，主要表现为细胞器发生较大变化，如出现叶绿体肿胀变形、线粒体数量增多，质膜模糊不清等现象；随接种时间的延长，细胞器受到进一步损伤，叶绿体被膜折皱，严重时局部破裂，基质外渗，并部分最终解体；(4)毛白杨中的菌丝主要在细胞间隙中穿行，而北京杨的菌丝除在细胞间隙中生长之外，侵入细胞内部也较多，直接导致细胞的解体；(5)干旱胁迫下细胞的损伤促进了病原菌的侵染，干旱和病原菌的双重胁迫加剧了病害的发生程度，并且病原菌侵染对细胞的破坏程度大于水分胁迫。

The results showed that the photosynthetic rate of B.stamineus decreased with the increasing of the drought gradient,but the decrease amplitude was less.The photosynthetic rate of B.inermis decreased indistinctively with the increasing of the drought gradient in the prometaphase,decreased distinctively in the later stage.

结果表明：美国无芒雀麦的光合速率基本上随着干旱梯度的增加而逐渐下降，在不同胁迫天数间也逐渐下降，但下降幅度较小；本地无芒雀麦各干旱处理光合速率在胁迫前中期随胁迫梯度的增加下降不明显，到胁迫后期才表现出较为明显的下降趋势，但在各胁迫天数间差别不大，仅在胁迫第20 d各处理光合速率较之前有较为明显的降低。

With aggravation of drought stress, ZXY04P-75 and ZXY04P-201 increased in proline content while that of ZXY03P-173 and ZXY04P-239 increased initially, reaching the peak at the 8th day, then declined. And the rate of net photosynthetic declined notably with the intensity of drought stress, The minimum of decline rate of net photosynthetic is ZXY04P-201. 4. The results of photosynthetic mechanism for 4 Dactylis glomerata L. show: the net photosynthetic rate, transpiration rate,stomatal conductance and chlorophyll decreased dramatically, Compared with weak drought resistance ZXY04P-239,the net photosynthetic rate, transpiration rate, stomatal conductance and chlorophyll in the leaves strong drought-resistance ZXY04P-201 decreased slowly.

连续水分胁迫及复水条件下4份鸭茅抗旱机理的研究表明，叶片水分饱和亏缺随着干旱胁迫强度的增加而增加，其中变化幅度最大的是ZXY04P-239，最小的是ZXY04P-201；ZXY03P-173和ZXY04-201质膜相对透性和可溶性糖含量随着干旱胁迫强度的增加而增加，而ZXY04P-75和ZXY04P-239出现单峰变化，在胁迫第8d后达到最大，然后下降；ZXY03P-173和ZXY04P-239脯氨酸含量在干旱胁迫第8d达到最大，而ZXY04P-75和ZXY04P-201的脯氨酸含量随着干旱胁迫程度的加深而逐渐达到最大；4份材料叶片的净光合速率随着干旱胁迫强度的增加而减小，其中ZXY04P-201的净光合速率下降率胁迫至12d时为最小。

As to'Cabemet Sauvignon'and'Queen of Vineyard', which belong to the'West Europe Cultivars Group', no obvious decline of Fv/Fm was found in their potted plants even under severe drought stress. Their photosynthetic abilities also greatly recovered after rewatering, i. e. no serious photodamage was formed in these cultivars under drought stress. Between them, the φPSⅡ of 'Queen of Vineyard'under severe drought stress was much lower than that of'Cabernet Sauvignon', which suggested that the light use efficiency of the former was much lower than the latter under severe drought stress. The potted plants of'Autumn Royal'and'Rizamat' sustained high Fv/Fm and φPSⅡ before moderate drought stress, but seriously declined under severe drought stress, which indicated that these cultivars had a weak resistant ability to extreme drought stress. A hybridized cultivar of Vitis vinifera L. and V. labrusca L.,'Red Double Taste', its Fv/Fm and φPSⅡ expressed mild decline along drought stress grade.φPSⅡ of'Red Double Taste'was the highest among seven cultivars under severe drought stress condition, which might closely connected with its high photorespiration activity. Another new cultivar,'Red Globe', and a rootstock,'1103Paulsen', the Fv/Fm and φPSⅡ of their potted plants declined markedly under slight drought stress, which suggested that they held a weak ability to defend against photoinhibition.

西欧品种群的赤霞珠和葡萄园皇后，其盆栽苗的Fv／Fm直到重度干旱胁迫下仍没有明显的降低，且复水后光合能力恢复程度较高，即干旱没有给这两个品种造成严重的光破坏，而两个品种之间，葡萄园皇后在重度干旱胁迫下的φPSⅡ明显低于赤霞珠，说明其光合器官在严重干旱胁迫时对光能的利用率较差；新品种皇家秋天和东方品种群的里扎马特在中度干旱胁迫下仍可维持较高的Fv／Fm和φPSⅡ，但在重度干旱胁迫下则降低幅度较大，说明其抵御极端干旱胁迫的能力较差；欧美杂种红双味的Fv／Fm和φPSⅡ随着干旱胁迫程度的增加呈现平缓的下降趋势，而且其φPSⅡ在重度干旱胁迫下是七个品种中最高的，这应该与其此时仍维持较强的光呼吸活性有关；红地球和砧木1103Paulsen的Fv／Fm和φPSⅡ在轻度干旱胁迫下就明显下降，表明干旱条件下其抵御光抑制的能力较差。

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。

Applied with test of potted plant and measurement absorbency for study response of the contents of photosynthetic pigments of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of photosynthetic pigments are mensurated under feebleness water stress while soil water content is 55% to 60% and moderate water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of chlorophyll and chlorophyll a and chlorophyll b and Chla/Chlb and carotenoid and Caro/Chl are mighty notable difference. The Chl and Chla and Chlb and Chla/Chlb little drop from normal soil water to initial water stress. Then drop obvious with increased water stress. The Caro and Caro/Chl little drop firstly from normal soil water to initial water stress,then up in metaphase water stress,after drop in evening water stress. The Chl and Chla and Chlb and Chla/Chlb and Caro of slash pine'half-sib are over general slash pine. The Chl and Chla and Chlb and Chla/Chlb and Caro of 464 and 1027 are over average value of slash pine's half-sib under water stress. The Caro/Chl of 609 and 46 are over average value of slash pine's half-sib under water stress.
