In this studay, pot experiments were carried out to learn the contribution of different organs to grain weight through the treatments of defoliate, darken ear and darken stem and the microstructure of rachis in different genotype wheat under water stress.

本研究选用不同小麦品种，采用盆栽试验，通过水分胁迫处理以及剪叶、包穗、包茎处理，研究了水分亏缺下不同器官光合产物对籽粒产量的贡献以及穗轴显微结构的变化，测定了水分亏缺下小麦不同生育期叶片保护酶活性、蔗糖磷酸合成酶的活性以及光合特性等生理指标。

In dicotyledonous and nongraminaceous plants, NAS synthesizes nicotianamine which is responsible for iron storage and transportation, and the expression of NAS gene is not induced by iron deficiency.

在双子叶和非禾本科单子叶植物中，烟酰胺的主要功能是铁离子的储藏和运输，NAS基因的表达不受缺铁胁迫诱导。

ESTs analysis showed that each gene expressed diversely in different tissues and under different stresses, which suggested specific function of particular gene.

通过ESTs搜索发现这些基因在水稻不同组织和不同胁迫条件下的的表达情况存在较大的差异。

When tested by artificial ecological encloser, all tested aquatic plants grew well andimproved water quality and transformed the trophic state of the reservoir, and so did theircommunities combined with several aquatic plants such as E.

这些结果说明ACU具有明显的缓解铜胁迫对菹草的毒害作用，并且在一定程度上可促进菹草的生长发育。

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 results indicate that fenugreek was tolerant to 0.5% NaCl stress, and could bear salt stress at some degree.

上述两方面的研究证实，胡芦巴种子及其幼苗能耐受0.5%的NaCl胁迫，表明胡芦巴具有一定的耐盐性。
