The purpose of this paper is to develop a system for tissue culture and rapid propagation of two ornamental lupins, Minaretie and Russell Prize. In view of screening out the better explant regeneration and suitable culture medium, through adding hormone 6-BA, NAA and 2, 4-D into MS and B5 basic culture medium, a series of experiments were carried out with the shoot tips, leaves, leaf petioles and stems from the asepsis seedling. The results showed that the shoot tips had favorableness on the rapidly propagation; MS＋6-BA 0.5 mg. L-1 for first generation, the induction rate of Minaretie and Russell Prize was 90.5% and 95.86% respectivdy; Minaretie had the highest propagation index （6.35） on MS＋6-BA 0.5 mg.L^-1＋NAA 0 mg-L^-1＋GA 30.8 mg.

Neural Regeneration Research 2010年第12期5卷 938-941页

作者： Yingzhi Lu Wenbin Zong Hanzhen Dong faxin wang Jinyu PU Xingshi Chen Yunxiang Tang Department of Psychiatry Fifth People's Hospital ofZibo Zibo 255120 Shandong Province China Department of Neurophysiology Shanghai Mental Health Center Shanghai Jiao Tong University Shanghai 200030 China

BACKGROUND： Study results of event-refated potential in obsessive compulsive disorder （OCD） remain controversial, potentially as a result of different instruments utilized and their differing technical characteristics. OBJECTIVE： To investigate the differences in several common event-related potentials, Le. contingent negative variations, P300, and mismatch negativity （MMN）, in OCD patients, depression patients, generalized anxiety disorder （GAD） patients, and healthy controls. DESIGN, TIME AND SETTING： A case-control study was performed in the Department of Electrophysiology, Shanghai Mental Health Center from May 2002 to December 2005. PARTICIPANTS： A total of 38 OCD patients, 20 depression patients, and 18 GAD patients, who were diagnosed according to the criteria of Chinese Classification of Mental Disorders （Version 3）, formulated by the Chinese Psychiatry Association, were selected from the Outpatient Department of Shanghai Mental Health Center. Patients with two or more the above diseases were excluded. In addition, 28 healthy people, gender and age matched, were selected as controls. METHODS： Contingent negative variations, P300, and MMN were recorded by a Nicolet Spirit Instrument. All electrodes were attached at Cz according to the Intemationa11020 system, with the mastoid leads as reference and Fpz as ground. MAIN OUTCOME MEASURES： Amplitude and latency of contingent negative variations, P300, and MMN. RESULTS： The contingent negative variations, P300, and MMN were different （P 〈 0.01）. OCD patients showed an increased MI amplitude compared with controls, depression, and GAD patients （P 〈 0.01）. Target P300 amplitudes were significantly lower in OCD, depression, and GAD patients compared with controls （P 〈 0.01）. Moreover, N2 latency and latency of MMN were prolonged in OCD and depression groups compared with controls （P 〈 0.05）. CONCLUSION： Event-related potentials were different in depression, GAD, and OCD patients and healthy controls. In particular, O

为摸索旱作物在生育期内利用浅层地下水的规律,减少旱作物的灌溉频次和灌溉量,提高农业节水效率,在淮北平原五道沟水文水资源实验站进行了浅层地下水位埋深影响旱作物生长的试验,对比分析了淮北平原两种典型土壤(砂礓黑土和黄潮土)种植小麦和大豆两种旱作物时利用浅层地下水的程度,从而确定这两种土壤在小麦和大豆生长期的地下水适宜埋深。结果表明,旱作物的生长过程与利用浅层潜水位关系复杂,且不同土壤类型、不同作物存在最佳的地下水位埋深。

针对淮北地区水土流失问题,利用野外人工模拟降雨试验,分析了不同雨强(40mm/h、60mm/h和80mm/h)和坡度(5°、10°和15°)条件下砂姜黑土和黄潮土产流产沙差异。结果表明:砂姜黑土初始产流时间长,产流总量小。坡面出现细沟时,砂姜黑土初始含沙量随时间变化有减小趋势,最终趋于稳定,而黄潮土含沙量呈波动变化;60mm/h、80mm/h雨强10°坡砂姜黑土产沙总量大于黄潮土,其他情况黄潮土产沙总量大于砂姜黑土,黄潮土土壤侵蚀严重。砂姜黑土表面细沟发育密度大,主要在坡面中下部,为相互连通的树枝状结构,而黄潮土表面细沟发育密度小,形成沟壑。两种土壤产流总量、产沙总量与坡度、雨强分别呈多元线性函数、多元幂函数关系,雨强对坡面产流产沙总量的影响大于坡度。

为确定淮北平原小麦生长期的适宜地下水位控制埋深,以2011-2013年淮北平原五道沟试验站实测资料为例,选取控制埋深为0.2、0.4、0.6、0.8、1.0、1.5、2.0m的全部装有砂礓黑土的测筒21只,每个埋深处理重复三次,分两期进行不同地下水位控制埋深对小麦产量影响的试验,通过控制测筒内地下水位埋深,比较不同地下水位埋深对小麦产量和构成的影响。结果表明,2.0m埋深以内,地下水位埋深与小麦产量显著相关,且用二次曲线可很好地拟合,小麦产量最高处对应的地下水位埋深约为1.3m。从产量构成的角度来看,小麦的株高、穗长和亩穗数均随地下水位埋深变化而差异显著,且2.0m埋深以内地下水位埋深与小麦产量之间呈现先增大后减小的关系。
