抗旱

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。

Applying "Method of Coleoptile Length" under five different PEG6000 concentrations(0、15%、20%、25%、30%),the study on 7 triticum aestivum varieties with different early draught-resistance by germination experiment inside room was carried on.

通过室内发芽实验，应用"胚芽鞘长度法"以PEG6000五个浓度处理(0、15%、20%、25%、30%)，对7个抗旱性不同的冬小麦进行了萌芽期抗旱性影响的初步研究。

The levels of drought tolerance and nucleotide polymorphism at CBF4 locus in a worldwide sample of 17 core accessions of Arabidopsis thaliana were examined. The results showed that different accessions had quite difference in adaptation to drought stress.

以生长于不同生态气候条件下的17个拟南芥核心生态型为材料，分析了它们的相对抗旱性和抗旱转录因子CBF4 基因的单核苷酸多态性。

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。

Leaf which the potato is planted in the dankness area has a higher chlorophyll A, B content, and the ratio of chlorophyll B/A.

阴湿地区种植的马铃薯叶片中叶绿素a、b及b/a比值较干旱地区高，而干旱地区马铃薯叶片中叶绿素b/a比值与品种抗旱性呈极显著的正相关，且叶绿素b含量愈高，品种抗旱性愈强。

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。

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 main purpose of this paper was to explore the methods of drought tolerance evaluation,and to evaluate the relationships between some agronomic traits and physiological indicators with drought-tolerance in foxtail millet.

探讨作物抗旱性分析评判的方法，对谷子主要农艺性状和部分生理指标与抗旱性之间的关系进行综合评价。

Evaluation was made for 113 lines about introgression effects.

对5个抗旱导入系群体抗旱选择导入效应进行了综合评价。

The results showed that the two conclusions of drought –resisting sequence got by the methods of coleoptile length in germination period and drought index in field test were basically consistent. The conclusions mentioned above pointed that the method of coleoptile length was effective to identificate drought-resisting wheat germplasm in early stages.

两者对比发现：利用胚芽鞘长度法对萌芽期冬小麦抗旱性强弱的鉴定结果与田间试验下苗期及产量表现综合分析所得出的抗旱性强弱顺序基本一致，说明胚芽鞘长度法对于早期鉴定抗旱小麦种质具有一定的可行性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
