干旱

Durum wheat is tetrapolid (28 chromosomes) and contains two basic genomes, whereas common bread wheat (Triticum spp.) is hexaploid and contains three basic gonomes. Durum is best adapted to growing in arid regions of the world: Italy and other areas in Southern Europe; Turkey and Syria in the Near East; Morocco and Algeria in Africa; Soviet Union; and Canada and Northern United States in North America.

多伦小麦产品是四倍体(28个染色体)并包含两个基本基因组，而普通的面包粉是六倍体并包含三个基本基因组，多伦小麦可以很好的适应生长于世界上的干旱地区环境，例如：意大利和南欧一些地区；近东的土耳其和叙利亚；非洲的摩洛哥和阿尔及利亚；前苏联；以及北美洲的加拿大和美国北部。

Plant's drought resistance can be better embodied under drought condition; the plants with high drought resistance have strong dynamic adapting ability.

植物的抗旱性在干旱条件下才能更好的体现出来；抗旱性强的植物更具动态的适应能力。

They are some eatable frutex, especially in drought grassland.

在干旱草原和荒漠化草原上，柠条是一种良好的饲用灌木。

We decide the fit breed of each place according to the geographical and periodical seeding experiments: FD1 like gongnongyihao fits the drought-cold areas such as Changling; FD3-5 like Haygrazer, Vector, Key etc fit the Huabei area such as Beijing and Taiyuan; FD6~8 like Lobo, Durango Eclogue, Titan802 etc fit the middle and lower reaches of Yangzi river such as Zhengjiang.3.During the course of climatic ecology division of alfafa, accumulated temperature above 5℃ is used as the main index, by gradually division, the whole country is divided into 6 climatic zones, namely Northeast zone, Huanghuai zone, Yangzi river valley zone, Northwest of Mongolian zone , Qingzang altiplano zone and unfit zone of South China. In each climatic zone, based on the main and secondary indexes, the climatic zones is divided into second climatic ecology regions, such as north of Xinjiang region, south of Xinjiang region and south of Tibet region etal, total 21 regions.

地理分期播种试验，确定了各地适合品种：以长岭为代表的干旱高寒气候适合种植秋眠1级品种，如公农一号；以北京和太原为代表的华北地区适合种植秋眠级3～5级的品种，如Haygrazer、Vector、Key等；以镇江为代表的长江中下游地区适合种植秋眠级6～8级的品种，如Lobo、Durango、牧歌、巨人802等品种。

In addition, the promoter of SRPP gene contains a variety of stress-responsive elements, such as HSE,MBS, TC-rich repeats, ABRE, EIRE and W box etc. These data suggest that SRPP is not only involved in rubber biosynthesis, but also plays an important role in response to various stresses in rubber trees.

此外，SRPP基因启动子还具有热激响应元件、干旱胁迫响应元件、防卫和胁迫响应元件（TC-rich repeats）、脱落酸响应元件、赤霉素响应元件和激发子响应元件等，这表明橡胶树SRPP基因不仅参与调控橡胶生物合成，而且可能是橡胶树中响应逆境信号的抗性基因，在橡胶树抵御逆境胁迫的生理过程中发挥重要作用。

The appearance of smectite suggests that it enriched in magnesium, but no strong eluviation, which belongs to cold and arid acid environment. 5 Three soil sites have different moisture.

水云母类矿物处于风化的初级阶段，蒙皂石的出现，反映了本地区富含镁元素，是没有强烈淋溶、寒冷干旱的弱酸性环境。

Under drought stress, 5mmol/L and 10mmol/L Ca~(2 ) test can increase thecontent of endogeny calcium, then improve the drought resistance of strawberry. And5mmol/L Ca~(2 ) test can increase the content of endogeny CaM, because CaM adjustinner enzyme activity, improve the drought resistance of strawberry.

在干旱胁迫下，5mmol／L和10mmol／L钙处理能提高草莓内源钙含量，从而提高草莓的抗旱性。5mmol／L钙处理能提高草莓内源钙调素含量，是由于钙调素调节了体内酶的活性，从而增强了草莓的抗旱性。

The effects of endophyte infection on the activities of SOD, POD and CAT, as well as on MDA contents in Lolium perenne under drought stress and osmotic stress were studied.

比较了两种不同的水分胁迫方式(田间干旱胁迫和温室渗透胁迫)下，内生真菌感染对黑麦草叶内SOD、POD和CAT活性以及MDA含量变化的影响。
