In crossing of the 8 autotetraploidy rices (Oryza sativa, 2n=4x=48), APIV(4), IR36(4), Zixuedao(4), Ce 64(4), Minghui 63(4), IR28(4), Ce 90(4) and Gui 99(4) used as the females, with Pennisetum alopecuroides (2n=2x=18) used as the males, the seeds were obtained, but no seed was got in the crosses of the 3 diploidy rices (Oryza sativa, 2n=2x=24), APIV(2), Ce 90(2) and Zixuedao(2) used as the females, with Pennisetum alopecuroides.
利用APIV(4)、IR36(4)、紫血稻(4)、测64(4)、明恢63(4)、IR28(4)、测90(4)和桂99(4)等8个同源四倍体水稻(Oryza sativa, 2n=4x=48)为杂交母本,以狼尾草(Pennisetum alopecuroides, 2n=2x=18)为杂交父本进行杂交,获得了实粒种子。但是,在以APIV(2)、测90(2)和紫血稻(2)这3个二倍体水稻(Oryza sativa, 2n=2x=24)为杂交母本,以狼尾草为杂交父本的杂交组合中却没有获得实粒种子。

The results showed that diploid and tetraploid had higher root activity, flagleaf soluble protein content, SOD and CAT activity before anthesis. However, the rootactivity, flag leaf soluble protein content, SOD and CAT activity of diploid and tetraploiddeclined more quickly and became lower than those of hexaploid species from 15 days afteranthesis. While MDA content increased more quickly and became higher than those ofhexaploid species from 5 days after anthesis. Correlation analysis showed that delaying the flag leaf senescence can promoted transfer of nitrogen and dry matter, increasedaccumulation of nitrogen and dry matter after anthesis, enhanced grain and protein yield.
结果表明,与普通小麦和小黑麦相比,二倍体和四倍体材料开花以前具有比较高的根系活力、可溶性蛋白含量、SOD和CAT活性;开花以后,根系活力、旗叶可溶性蛋白含量、SOD和CAT活性快速下降,MDA含量快速上升,衰老加快;相关分析表明,延缓小麦旗叶衰老进程,可以促进花后氮素和干物质运转,增加花后氮素和干物质积累,提高籽粒产量和籽粒氮素积累量。

The temperature affects partition of dipotassium glycyrrhizinat but the effect is minor. On the same time pH has major impact on the partition of dipotassium glycyrrhizinat. The coefficient is eight times higher when pH reaches 2. The improved Diamond-Hsu model can be used to correlate the partition coefficient of dipotassium glycyrrhizinat in the system of water/ethanol/isobutanol. The result of Infrared and TG analysis indicate the extraction product has the same characteristic features with dipotassium glycyrrhizinat.
结果表明:体系的初始点越靠近临界点,甘草酸二钾的分配系数越大;温度对甘草酸二钾的分配有~定的影响,但分配系数随温度变化不大;pH值对甘草酸二钾的分配有较大的影响,在pH=2附近,分配系数高出其他位置达8倍;改进的Diamond-Hsu模型可以用于关联甘草酸二钾在水+乙醇+异丁醇体系中的分配系数;红外和TG分析结果表明萃取产物与甘草酸二钾样品的性质特征相同。
