Suitable control content of culture medium can benefit growth, proliferation rate of Williams B6 seedling, save spending of production material. The content of 30ml per bottle show the highest proliferation rate and the higher usage of culture medium, the contrary result will appear when preponderate over the content of 30ml per bottle, but the increase weight of single seedling. For the losing of medium by sterilization, seedling SO2 resistance and other effects, it's considered the content of 25~30ml per bottle is fit for production of tissue culture seedling.

适宜控制培养基用量，能稳定威廉斯B6香蕉组培苗生长量、繁殖率，减少原料投入。30ml的用量其增殖率最高、培养基利用率较高，超过30ml的用量其增殖率相对下降，培养基利用率降低，但单苗增重量最大，综合考虑培养基损失、蕉苗耐SO2性等因素，认为培养基用量应控制在25~30ml/瓶。

The results showed that (1) the positive staining of ChAT was obviously observed in the cells of the three kinds of human pituitary adenoma, however, it was lower than that in normal human pituitary gland;(2) ACh had a similar effect on the proliferation of the three kinds of human pituitary adenoma cells. ACh at 0.1～10 μmol/L decreased the ［3H］TdR incorporation and the MTT A value in a dose-dependent manner. At the same time, ACh decreased the ratio of S or G2 phase pituitary adenoma cells significantly, but increased the ratio of G1 phase pituitary tumour cells markedly;(3) the effect of acetylcholine on the proliferation of human pituitary adenoma cells was inhibited by atropine, but not by tubocurarine;(4) ACh had no effect on the apoptosis of human pituitary adenoma cells cultured in vitro.

MTT细胞增殖实验、细胞周期及凋亡分析、细胞侵袭迁移实验、细胞粘附实验显示，GEBP11短肽对Co-HUVECs及HUVECs的增殖表现出不同程度的抑制作用，对Co-HUVECs抑制作用更强，GEBP11能诱导内皮细胞的凋亡，而对细胞周期无明显影响。

The number of differentially expressed genes was 71 at 24h, and 62 at 72h. The metabolisic gene class was the majority among all the differentially expressed genes, and the next was transportational、differentiation and adhesional gene class by turns.1.2. RT-PCR verification of the known HIF-1 targeted genes and proliferation related genesIn the 131 differentially expressed genes, we found 7 known HIF-1 targed genes (ldha、aldoa、eno1、gapdh、tpi1、pgk1、bnip3) and 5 genes (dnaja2、ccnb1、tgfβ2、ccng1、rgs7) which were related to proliferation and cell cycle.

The results were showed that embryogenic calli were induced from young leaves, which were cultured on MS medium supplemented with 2,4-D 2mg/L and KT 0.2mg/L. For the proliferation of embryogenic calli, the suitable culture medium was MS+BA 8mg/L +NAA 1mg/L. The development and maturation of somatic embryo could be much improved by using the medium of MS+ZT 2mg/L or BA 5mg/L +IAA 0.2mg/L. For the induction of secondary somatic embryo from integral somatic embryo, the suitable culture medium was MS+KT 0.1mg/L+NAA 0.01 mg/L or MS+ZT 0.1mg/L+NAA 0.01 mg/L, the proliferation frequency is 214%, 256% respectively.
