负离子快原子轰击及其碰撞活化质谱法在寡糖苷结构分析中的应用

The total RNA from brain tissue of substantia nigra of PD rats is extracted at the 1st, 2nd, 4th and 8th week and comparison is made between it and that from normal rats. The total RNA, after RNA formaldehyde degenerated sepharose electrophoresis and separation and Northern transfer, is adsorbed unto colloxylin membrane. Then ECL labeled Selenoprotein P and an unknown gene fragment are used as probes to hybridize with the RNA on the colloxylin membrane. And the hybridized result is obtained with enzyme-linked immunosorbent assay. Finally, analysis of OD is made using ONE-Dscan software.

With aggravation of drought stress, ZXY04P-75 and ZXY04P-201 increased in proline content while that of ZXY03P-173 and ZXY04P-239 increased initially, reaching the peak at the 8th day, then declined. And the rate of net photosynthetic declined notably with the intensity of drought stress, The minimum of decline rate of net photosynthetic is ZXY04P-201. 4. The results of photosynthetic mechanism for 4 Dactylis glomerata L. show: the net photosynthetic rate, transpiration rate,stomatal conductance and chlorophyll decreased dramatically, Compared with weak drought resistance ZXY04P-239,the net photosynthetic rate, transpiration rate, stomatal conductance and chlorophyll in the leaves strong drought-resistance ZXY04P-201 decreased slowly.

连续水分胁迫及复水条件下4份鸭茅抗旱机理的研究表明，叶片水分饱和亏缺随着干旱胁迫强度的增加而增加，其中变化幅度最大的是ZXY04P-239，最小的是ZXY04P-201；ZXY03P-173和ZXY04-201质膜相对透性和可溶性糖含量随着干旱胁迫强度的增加而增加，而ZXY04P-75和ZXY04P-239出现单峰变化，在胁迫第8d后达到最大，然后下降；ZXY03P-173和ZXY04P-239脯氨酸含量在干旱胁迫第8d达到最大，而ZXY04P-75和ZXY04P-201的脯氨酸含量随着干旱胁迫程度的加深而逐渐达到最大；4份材料叶片的净光合速率随着干旱胁迫强度的增加而减小，其中ZXY04P-201的净光合速率下降率胁迫至12d时为最小。

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。
