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。

Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.

结果表明：1未劈裂绵刺主要通过增加细胞内溶质，减少细胞内的水分丧失来进行渗透调节，从而在干旱胁迫下能够维持正常的膨压。2己劈裂绵刺通过渗透调节和高的组织弹性两条途径来共同保持膨压，以抵抗不良的生存环境；同时对环境水分胁迫具有较高的敏感性。33种状态绵刺保持膨压的能力由强到弱依次为：未劈裂绵刺、正在劈裂绵刺、已劈裂绵刺。4劈裂的发生导致绵刺保持膨压能力的降低，同时耐旱方式和途径发生了变化。

The increscent of species biomass percentage, which is used to present the competitive ability of species growth, was not significantly correlated between un-drought plots and drought plots. This means that drought stress has significant effect on the competitive hierarchies of species growth characteristic.

以消亡百分率代表物种存活特征竞争能力，干旱胁迫和正常对照样地内物种消亡百分率之间存在显著正相关，存活特征的竞争等级未发生明显的变化，说明干旱胁迫对物种存活特征的竞争等级的影响作用较弱。

Drought stress weakened the rhizosphere effect of ammonifying bacteria.Under drought stress,rhizospheric ammonifying bacterium amount of Baidan31 was very significantly different at seedling and jointing,and significantly different at tasseling-anthesis from that of control.Rhizospheric nitrifying bacteria tended to increase under drought stress.

干旱胁迫减弱了玉米氨化细菌的根际效应，与对照根际氨化细菌数量相比，白单31在苗期和拔节期根际氨化细菌数量受干旱胁迫的影响达极显著水平，在抽雄～开花期达显著水平；根际硝化细菌数量在干旱胁迫下有所增加。

Compared to the low drought-resistance BL-02-329, when subjected to drought stress, the net photosynthetic rate in the leaves of high drought-resistance alfalfa, Longdong, decreased more slowly and chloroplast shape and grana structure were less affected.

相对于抗旱性弱的苜蓿，抗旱性强的苜蓿随干旱胁迫程度的加深，净光合速率下降较慢，叶绿体的外形及基粒结构受到的影响较小。

5The height, length of leaves, width of leaves, fresh weight of single plant, fry matter weight of single plant, leaf areas of single plant, LAI, yield of single plant and yield components were reduced during drought stress at different growth stages. The decreased percent was the most great to grains per corncob at tasseling drought stress; hundred-grain-weight, at grain stage drought stress; yield of single plant, at booting-blossoming, and the extent was

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。
