The results showed that the mutant behaved etiolation character in different temperature and illumination time condition.

Extracts from 6 species of IPomoea batatas Lam leaves have been determined for their bacteriostatic effects on five types of pathogenetic bacteria (Escherichia coli,Bacillus subtilis, staphylococcus aureus, staphylococcus albus, and Proteus vulgaris) by using the methods of the filter paper disk test s and the dual-flat tests.

用滤纸圆片法和双层平板法测试六种不同品种红薯叶（SPGS—1，SPGS—2，SPGS－3，SPGC，SPRC，SPRS）的提取物对五种致病菌：大肠杆菌、枯草杆菌、金黄色葡萄球菌、白色葡萄球菌、普通变形杆菌的抑制作用、结果发现SPGS—1、SPGS—2、SPGS—3和SPRS四种红薯叶提取物有明显的抑菌作用，其最低抑制浓度范围为0.4g／ml～1·0g／ml

Results The learning and memory ability of experimental group was better than that in saline control group (P＜0.01), but there was no significant difference between experimental group and normal control group (P＞0.05).There was significant difference in cytochrome C of hippocamp and frontal lobe between saline control group and the other groups (P＜0.01).The expression of cytochrome C in hippocamp was higher than that in frontal lobe of experimental groups.

结果 NSCs移植后AD模型大鼠的学习记忆能力明显改善，与生理盐水对照组相比差异显著（P＜0.01），与正常组相比无显著差异（P＞0.05）；海马与额叶的CytC表达显示生理盐水对照组与其他各组之间有显著差异（P＜0.01）；各实验组海马内的CytC表达均高于额叶。

PIV technique, a non-touch measurement method, was used as the experiment means. The unsteady flow within the vanelesss and vaned diffuser were measured and analyzed first time in our country.

实验中采用非接触式的PIV光学测量技术，在国内首次使用PIV技术对无叶扩压器、有叶扩压器两种结构形式扩压器内部的非定常流动进行了测量，分析了其中的流动特性。

The height, stem of seedling, total length of roots; leaf area, chlorophyll content of plats which was sprayed with ABT 50 mg/L reached 27.53%, 61.54%, 70.91%, 64.23% and 21.43% respectively, which were higher than that of the control. NAA and ABT had obvious effects on accelerating o the seedling growth of Castanopsis fissa.

结果］2种生长调节剂对大叶栎苗木的生长有明显的促进作用，尤以喷施ABT 50mg/L的处理表现最佳，其苗高、地径、根系总长、叶面积、叶绿素含量分别比对照提高了27.53%、61.54%、70.91%、64.23%、21.43%。

Four-leaf clovers even pre-date shamrocks as lucky charms.

四叶苜蓿甚至提前生长的四叶苜蓿被认为有幸运的魔力。

Using SEM-EDX for observing the silicon deposition on leaf epidermal surfaces demonstrated that deposition density of silicon were different on leaf surfaces with the different silicon compounds was different, and effects of these compounds on wax layer also were different.

借助扫描电镜和X—射线能谱观察发现，不同硅源制剂叶面处理小麦后，硅素在叶表的沉积疏密度有一定的差异，同时对叶表的蜡质层影响大小也不同。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
