RESULTS: SEM results showed that the fiber morphology of P(50/50) 6% nanofibers membrance was better and more uniform diameter distribution. Mechanic test indicated nanofibers membrance of P(50/50) had longer breaking elongation but smaller breaking stress than nanofibers membrance of P(75/25). Hydrophilicity of P(75/25) fibers was better. MTT results proved that 6% and 8% P(50/50) nanofibers could enhance the adhesion and proliferation of endothelial cells on the surface of materials, and the cells had the best spreading and attachment on the nanofibers.
结果:通过扫描电镜观察发现由质量分数为6%聚(50/50)制备的纤维膜具有更好的纤维形态,且直径分布均匀;拉伸力学测试显示由聚(50/50)制备的纤维膜比聚(75/25)具有更高的断裂伸长率,但断裂应力较低;细胞生物相容性实验表明猪髋动脉内皮细胞在质量分数为6%和8%聚(50/50)的纳米纤维膜上更能有效的黏附与增殖。

Red light can also reduce gibberellin content, which minishes internode length and plant height; however, far red light (700 -800 nm) can have the opposite affect and enhance GA.
光同时是植物形态形成的信号源。600~700nm的红光能降低植物体内赤霉素的质量分数,从而减小节间长度和植株高度;而700~800nm的远红光能提高体内赤霉素的质量分数,从而增加节间长度和植株高度。
