抗旱的

A set of recombinant inbred lines population including 195 lines derived from a cross of Zhenshan 97B and IRAT109 was used for correlation analysis and QTL identification for coleoptile length and drought resistance index.

对由水稻品种珍汕97B和旱稻品种IRAT109构建的重组自交系195个株系的胚芽鞘长度及抗旱系数的研究表明，水分胁迫下水稻重组自交系群体的胚芽鞘长度与抗旱系数的相关系数为0。

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。

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。

Soil is a notable controlled object as carrier of water and nutrients required by plant growth and development, and reasonable treatments of it are closely related with drought resistance.

干旱条件下培育人工植被，采取适当的抗旱措施是必不可少的，其中作为植物生长发育所需水分、营养的载体，土壤是显著的可调控对象，对其合理处置与抗旱有着密切的关系。

The result showed that the seed which were dealt with EM, Handilong, solution of wood vinegar and distilled water represented various degree difference on the morphological characteristic at the seedling stage and each drought-resistance physiological index.

结果表明，经过EM、旱地龙、木醋液、蒸馏水浸种的：种子在苗期形态特征和各项抗旱生理指标都表现不同程度的差异，EM、旱地龙浸种后植株的抗旱能力的提高要好于蒸馏水、木醋液，并且植株的形态结构趋于优化。

It was concluded that Glomus mosseae inoculation improved the drought resistance of Broussonetia papyrifera Vent, especially in moderate stressed conditions. And the contribution of AM symbiosis to plant to avoid the stress or to increase its tolerance might be the result of modification of root morphology and fractal character.

由此作者认为，接种G.mosseae在不同土壤水分条件下促进了构树幼苗的生物量积累，这种促进作用在土壤干旱条件下尤为明显，表明AM菌根真菌G.mosseae提高了宿主构树的抗旱性；G.mosseae对宿主构树抗旱性的提高与G.mosseae对构树根系形态特征、分形特征的改变密切相关。

In this research, many indices of drought resistance during germination stage and seedling stage were chosed to evaluate comprehensively the drought resistance of 20 Dactylis glomerata L. germplasm from abroad.

以国外引进的20份野生鸭茅种质资源为研究材料，通过萌芽期PEG模拟干旱试验、幼苗期温室盆栽试验，系统测定了干旱胁迫下鸭茅种质萌芽期种子萌发抗旱指数、胚根、胚芽，幼苗期幼苗株高、根冠比、叶片水分饱和亏缺、质膜透性、脯氨酸含量等形态和生理指标，全面分析了这些指标的变化规律，对所引进的20份鸭茅种质的抗旱性进行了综合评价。

The results were as follows: 1. Response of physiology indices of Medicago falcata L. to drought stress is different. There are not obvious correlation among indices and ability to drought resistance. The indices include critical water saturation deficiency, free and bound water content, tissue water, peroxidase isozyme, free proline content, chlorophyll a, chlorophyll b, total chlorophyll and chlorophyll. These indices are not fitting for assessing ability of drought resistance of Medicago falcata L..

黄花苜蓿各生理指标对干旱胁迫的响应不同，临界饱和亏、自由水含量、束缚水含量、组织水含量、过氧化物同工酶、游离脯氨酸含量、叶绿素a、叶绿素b、叶绿素总量以及叶绿素与黄花苜蓿抗旱能力之间不存在明显的相关性，不适宜采用这些指标来评价或判别黄花苜蓿材料间抗旱能力的强弱。

The ability of combating a drought is controlled by many characters of wheat could control it.

小麦的抗旱能力是受多因素控制的数量性状，抗旱能力的高低是在多种因素共同作用下的综合反映。

So wc concluded that HS1 had the same strcss tolcrancc ability in thc rye grass,which was suitablc for hcrcdity improvcmcnt.

因此，我们认为来源于拟南芥的HS1基因在黑麦草中同样具备抗旱耐盐的生理功能，是一个适合用做抗旱耐盐遗传改良的重要基因。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
