作者： Shuang Qing Liu zu Han Liu Wei Guo Wang Yue Ping Lu Xiao Liang Zhu bin Guo School of.Inf.rm.tion Engineering Nanchang Institute of Technology Key Laboratory of.the Education m.nistry f.r Poyang Lake Wetland and Watershed Research Jiangxi Normal University Research Center f.r East-West Cooperation in China East China Normal University

Based on the hydrological data in the headwater region of.the Kaidu River during 1972-2011, the m.ltif.actal process of.runof. f.uctuation was analyzed. Results indicated that, in the past 40 years, the overall runof. of.the Kaidu River in Xinjiang has shown signif.cant m.ltif.actal behavior. Its singular curve 1nχq（ε）-1n（ε） verif.ed a f.vorable scale invariance over the entire tim. scale, r（q）-q proved that evolution of.the runof. tim. series presented m.ltif.actal characteristics. m.reover, the m.ltif.actal spectrum.（α）-α curve was hooklike lef.ward which indicated that, com.ared to relatively large runof. events. And △f.0 indicated that these relatively sm.ll events took the leading role; B〈0 explained the Kaidu River＇s daily-runof. ascending tendency presented during 1972-2011. Besides that, the m.ltif.actal behavior of.the Kaidu River＇s runof. variability over f.ur decades was also analyzed. Generally speaking, by decades, their f.ur corresponding spectrum.variations were not noticeable. These △α values showed larger runof. events occupied the leading position with som. local values f.lling. During the 1970s to the 1990s, △f.0 illustrated the probability of.the daily runof. at the lowest point is always larger than that of.the highest during three continuous decades. At the beginning of.the 21 st century, f.r △f.0 the trend presented was contrary f.om.the 1970s to the 1990s. B values suggested an overall trend of.increases during 1972-2011. Until the 21 st century, the runof. with a slightly descending tendency on the whole explained these relatively large runof. events taking the leading role f.r the Kaidu River; but som.tim.s, som. sm.ll events also played the dom.nant role.

在玉米m.o17/黄早四R)IL群体中,应用SSR分子标记连锁图谱,运用WinQTLcartographerv2.0对两种供氮水平下的穗长性状进行QTL定位分析。结果表明,在高氮水平下检测到1个控制穗长的QTL,位于第1染色体上;在低氮水平下检测到4个穗长QTLs,第1和第5染色体上各2个,说明穗长QTLs与供氮水平之间可能存在交互效应。基于这种互作效应及研究中观察到的两个供试亲本对低氮胁迫的耐性差异,推测仅在低氮水平下检测到的穗长QTLs可能与玉米对低氮胁迫耐性有一定的关联。

研究了向日葵茎芯中主要活性物质多糖的提取工艺,并对此工艺进行了优化,选取的提取方法为水提醇沉法,以多糖含量作为指标,采用单因素试验研究了提取次数、原料颗粒的大小(目数)、料液比、提取时间、提取温度对向日葵茎芯多糖含量的影响。用苯酚-硫酸法测定提取液中多糖的含量,得出向日葵茎芯中多糖的最佳提取工艺条件为:提取次数2次,原料颗粒的大小(目数) 60~80目,料液比(g·m.L^(-1)) 1∶50,提取时间3. 0 h,提取温度90℃,在最优提取条件下,多糖的提取得率为6. 56%,多糖的含量为266. 03 m.·g^(-1)。本文也对多糖的体外抗肿瘤活性进行了研究,结果表明向日葵茎芯多糖的体外抗肿瘤活性较弱。这些条件的确定为向日葵茎芯的深入研究奠定了基础。
