In order to research the sugar accumulating regulation of sweet sorghum, the relationship between the brix of every internode and average brix of its whole stem was studied. This paper used varieties MNS-1, MNS-2 and stem brix of sweet sorghum in different period. The result showed that the variation of early matured and late matured varieties of sweet sorghum had same tendency in brix in same growing period, but had different values.

为了解甜高粱茎秆中糖分积累规律，研究甜高粱自基部至顶部各茎节间锤度关系及各茎节锤度与主茎秆平均锤度的关系，以示范推广品种MNS-1、MNS-2为材料，测量了不同时期甜高粱的茎秆锤度值；采用相关等分析方法对各茎节间锤度及与主茎秆平均锤度的关系进行分析。

Determination of photosynthetic pigments used 80% of acetone extraction method directly and the photosynthetic characteristics of using Li-6400 portable photosynthesis detector. Results showed that Returning the right amount maize straw stem into field was able to significantly restraint this year winter wheat flag leaf Chla degradation, to raise the flag leaf Chla/Chlb in the watery metaphase and late stage, to effectively restraint the photosynthesis rate decrease in the watery stage, to increase the pertinence of photosynthesis rate and pigment compared to others. However returning more maize straw stem into field was able to accelerate the retrogradation of chlorophyll and photosynthesis rate decrease then the yield declined.

结果表明：适量的玉米秸秆还田(9 000 kg/hm^2)可显著抑制接茬冬小麦灌浆中后期旗叶Chla降解，提高小麦灌浆中后期旗叶Chla/Chlb的比值，有效抑制灌浆期旗叶光合速率的下降，与其他处理相比，其光合速率与叶绿素的相关性得到加强；过量的秸秆还田(15 000 kg/hm^2)，加速了光合色素的降解，使得光合速率下降，产量降低；在各处理中，处理Ⅱ(9 000 kg/hm^2)产量最高。

So it is generally assumed that tumor cells are derived from normal stem cells, more work is needed to identify and characterize epithelial tumor stem cells.

然而，目前研究中关于上皮肿瘤干细胞及其与正常上皮干细胞的关系了解甚少。

&我知道在美国很多人都愿意转移到胚胎干细胞的领域，但是碍于不明朗的政治因素，&伦敦King's College 干细胞生物实验室的主管Stephen Minger在他混乱不堪的办公室里对我说，&我认为美国真的有落后的危险。&

Laura Grabel, a professor of biology at Wesleyan, whose $800,000 research project focuses on epilepsy, has done some similar work using stem cells in mice, and said that using human stem cells would take the research one step closer to an ability to apply it in patients.

Laura Grabel是卫理公会派一名生物学教授，他的80万研究计划是有关惊厥，已经用鼠干细胞做了一些类似的工作，并且说：运用人干细胞将使该研究被用于人类的能力更进一步。

Results show that there is disparity in all treatments such as in days from cutting to flowering,stem length and stem thickness.

结果表明：在开花天数、花枝长度及粗度方面，各处理之间存在差异。
