胁迫的

The results indicated that:(1) plant height and tillering number decreased, and root length, root surface area, root volume and rootlet number increased under drought stress; straw mulched on surface soil and pig manure mixed in soil could improve the growth and morphological property of rice root, while straw mixed in soil and pig manure mulching had no significant effects;(2) the contents of chlorophylls and the activities of SOD, POD and CAT decreased significantly under drought stress, and straw mulching on surface soil and pig manure mixed in soil could restrain these decreases.

结果表明：①干旱胁迫下水稻株高降低、分蘖数减少，根系则表现出主根伸长、支根增多、根表面积和根体积增加；秸秆表施和猪粪混施可明显改善水稻的生长和根系形态，而秸秆混施和猪粪表施的改善作用不显著；②干旱胁迫下叶片叶绿素含量显著降低，超氧化物歧化酶、过氧化物酶及过氧化氢酶活性均显著下降，秸秆表施和猪粪混施能够在一定程度上抑制这种下降幅度。

Under lower potassium stress, the high efficiency ramie genotypes had higher growth potential (higher relative root dry weight, relative rootlet dry weight, relative root total and active absorb surface area), and higher relative fiber yield, decreased the negative effect of lower potassium stress on fiber quality validly.

但高效基因型苎麻低钾胁迫下仍具有较强的生长势（相对根系干重、相对细根干重、相对根系总吸收面积、相对根系活跃吸收面积较大），其纤维产量所受影响程度小于低效基因型，有效降低了低钾胁迫对纤维品质所引致的负面影响。

Effects of nitric oxide donor sodium nitroprusside with different concentrations on lipid peroxidation in rice seedling leaves under 100mmol^(-1) NaCl salt stress were investigated through 5d of treatment.

以100mmolL^(-1)NaCl作为盐胁迫条件，研究不同浓度的外源一氧化氮供体硝普钠(sodium nitroprusside， SNP)处理5d对盐胁迫下水稻幼苗叶片脂质过氧化的影响。

The situation that water potential and turgor pressure in plant reduced to disturb or destroy its regular metabolize enginery and physiological function, caused by water deficiency is called water deficit stress or drought stress.

由水分不足引起的植物水势和膨压降低到足以干扰甚至破坏其正常代谢机能和生理功能的情况，称水分亏缺胁迫或干旱胁迫。

Effects of different concentrations of NaCl on the physiological mechanism of yearling seedlings of Phyllostachys pubescens was studied by measuring some physiological parameters.

以1a实生毛竹苗为材料，通过测定在不同浓度NaCl胁迫条件下的各项生理指标，研究了NaCl胁迫对其生理机制的影响。

The damages of the leaves and roots tissues in Alternanthera philoxeroides were lighter than that observed in Orgza sativa under osmotic stress.

通过空心莲子草及水稻根和叶的组织结构比较观察发现，渗透胁迫下空心莲子草所受到的胁迫伤害比水稻要轻。

Is higher than Amygdalus communis L. A.persica and Amygdalus communis L had different change on Mineral Element under water stress. Ultrastructure of nutritional organs had gravely destroy under water stress

水分胁迫对毛桃和石头扁桃的矿质元素影响不一致，水分胁迫使毛桃和石头扁桃的细胞超微结构受到严重破坏。

The injury threshold values of most plants are observed at pH 2.0~3.5 designed in this experiment. However, those of Brassia campestris, Viola tricolors and Zephyranthes candida are not fixed at pH 2.0. It indicates that three herbaceous ornamental plants own a strong resistance to acid rain.

在设定的酸雨胁迫强度(pH 2.0~3.5)下，多数植物的伤害阈值可被确定，惟有羽衣甘蓝、三色堇和葱兰在pH2.0酸雨胁迫下仍无法确定其伤害阈值，表明此3种草本观赏植物对酸雨有极强抗性。

The activitys of Super Oxide Dismutase, peroxidase and Multiple Displacement Amplification of Ceratophyllum demersum L raised rapidly in the late of experiment, and the maximum value of MDA of Ceratophyllum demersum L in the eutrophic condition was 5 time higher than that in the medium nutritional condition, implied that Ceratophyllum demersum L has been stressed in the middle nutritional condition.

金鱼藻超氧歧化酶活性、过氧化物酶活性和丙二醛含量在试验后期上升速度加快，且富营养水平下金鱼藻MDA质量分数的最大值是中营养水平下最大值的5倍，表明在中营养水平下金鱼藻已经受到明显胁迫，而在富营养水平下受到胁迫更为显著。

During the experimental conditions, the activitys of SOD, POD and MDA of Ceratophyllum demersum L changed greatly, and raised rapidly in the late of experiment, which indicated that those two submerged macrophytes got more nutrient stress than Myriophyllum spicatum L, and the nutritional stress-resistant ability of Myriophyllum spi-catum L was higher than those two submerged macrophytes in the medium nutritional condition.

在本试验条件下，黑藻生物量小，而金鱼藻SOD活性、POD活性和MDA质量分数变化幅度大，在试验后期急速上升，表明这两种沉水植物受到的营养盐胁迫较狐尾藻大，而狐尾藻在中营养水平下的耐营养盐胁迫能力较强。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
