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 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 comprehensive evalucation resulted in a strong drought resistance group including ZXY04P-201、ZXY03P-227、ZXY03P-122 and ZX Y04P-136, a weak drought resistance group including ZXY04P-101、ZXY04P-89,ZXY04P-239 and a intermediate group including the others according to the the above indicators. 3. The results of study on drought mechanism for 4 Dactylis glomerata L. under continuously water stress and rewatering show: the water saturation deficit of leaves arose hastily, and ZXY04P-239 changed most obviously while ZXY04P-201 changed only slightly under drought stress. ZXY03P-173 and ZXY04P-201 increased in the relative plasmalemma permeability and the soluble sugar content while thant of ZXY04P-75 and ZXY04P-239 showed the trend of initial increasing, reaching the peak at the 8th day, then decreasing under drought stress.

20份鸭茅种质幼苗期抗旱性研究表明，干旱胁迫条件下，所有材料的株高、生物量显著下降，叶片脯氨酸和可溶性糖作为重要的渗透调节物质，其含量迅速增加，质膜相对透性的数值变大，细胞膜受伤害程度增大，水分饱和亏缺值变大，植物保水能力变弱，胞间CO2浓度增大；净光合速率、蒸腾速率、气孔导度和叶绿素含量等指标测定值减小，通过20份鸭茅种质苗期抗旱性综合评价，发现ZXY04P-201、ZXY03P-227、ZXY03P-122、ZXY04P-136属强抗旱性材料，ZXY04P-101、ZXY04P-89、ZXY04P-239属弱抗旱性材料，其他属于中等抗旱性材料。

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。
