Result At the end of dioestrus, the estradiol level was increased gradually, and the peak of estradiol appeared from 1 day before oestrus to 3 days after oestrus (52.50±29.26) pg/mL, then the estradiol decreased rapidly, its lowest value at 6-9 days of oestrus (7.20±5.50) pg/mL. The level of progesterone was low before oestrus, and rose gradually at the peak of estradiol and reached the highest value at 9-15 days of oestrus (35.52±7.87) ng/mL, then it decreased gradually.

结果 发情间期的末期，雌二醇开始升高，在发情前1 d至发情开始后3 d内出现雌二醇高峰(52.50±29.26) pg/mL，峰值后雌二醇急剧下降，到发情第6~9天下降至最低值(7.20±5.50) pg/mL；孕酮水平在发情前期较低，于雌二醇高峰时开始上升，发情第9~15天达到最高值(35.52±7.87) ng/mL，此后逐渐下降。

The results showed that, all the treatments can shorten the time of epicotyl germination of 'Fengdan', the 28 days chilling treatment was the shortest, and the next was 21 days chilling treatment and 300 mg/L GA3 treatment; in a certain range of GA3 concentrations, higher concentrations, higher seed germination index and germination rate in 'Fengdan'; the seed germination index and germination rate of 'Fengdan' after different time chilling treatments were higher than the control, in which, the treatment of 21 days chilling had the highest germination index and germination rate.

研究了不同时间的低温(4℃)处理及不同浓度的GA3处理对凤丹种子上胚轴萌发及幼苗生长的影响，结果表明：所有处理均能缩短凤丹种子上胚轴萌发时间，以低温28天处理初萌期最短，其次是低温21天和300mg/L GA3处理；在一定的GA3浓度范围内，浓度越高，凤丹种子发芽指数与发芽率越高；不同时间低温处理后凤丹种子发芽指数与发芽率均高于时照，其中低温21天处理是所有处理中发芽指数与发芽率最高的。

Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

NK细胞以其强大的细胞毒活性为特征，与细胞毒性T细胞相比，NK细胞具有如下特点：NK细胞虽然只占外周血淋巴细胞的10-15％，但是对刺激性因素产生应答的过程十分迅速，一次可以调动大多数细胞共同参与，而不是几个克隆的活化，免疫应答的强度高；病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失，并借助这一机制逃避特异性T细胞应答的识别，NK细胞介导的杀伤活性无需抗原刺激，不受MHCⅠ分子表达的限制，从而与T细胞应答互为补充发挥免疫防御的功能；NK细胞的免疫活性可以被多种细胞因子上调，其中IFNα，IL-2，IL-12，IL-15和IL-18具备更强的作用；NK细胞具有强大的细胞因子分泌功能，对于启动T细胞特异性应答必不可少。
