| 1 | Anatomical and chemical characteristics associated with lodging resistance in wheat显示文摘Anatomical and chemical characteristics of stems affect lodging in wheat(Triticum aestivum L.) cultivars. Traits associated with lodging resistance, such as plant height, stem strength, culm wall thickness, pith diameter, and stem diameter, were extensively investigated in earlier studies. However, the solid stem trait was rarely considered. In this study, we measured a range of anatomical and chemical characteristics on solid and hollow stemmed wheat cultivars. Significant correlations were detected between resistance to lodging and several anatomical features, including width of mechanical tissue, weight of low internodes, and width of stem walls. Morphological features that gave the best indication of improved lodging resistance were increased stem width, width of mechanical tissue layer, and stem density. Multiple linear regression analysis showed that 99% of the variation in lodging resistance could be explained by the width of the mechanical tissue layer, suggesting that solid stemmed wheat has several anatomical features for increasing resistance to lodging. In addition, microsatellite markers GWM247 and GWM340 were linked to a single solid stem QTL on chromosome 3BL in a population derived from the cross Xinongshixin(solid stem)/Line 3159(hollow stem). These markers should be valuable in breeding wheat for solid stem. | Eryan Kong Dongcheng Liu Xiaoli Guo Wenlong Yang Jiazhu Sun Xin Li Kehui Zhan Dangqun Cui Jinxing Lin Aimin Zhang | 2013 | The Crop Journal2013，1，1： | 43 |
| 2 | Dual-parameter shaping regularized full waveform inversion in frequency domain显示文摘The regularization contributes to the resolution and stability in geophysical inversion. The authors apply dual-parameter shaping regularization to full waveform inversion,aiming at two points:( 1) improving the boundary resolution,and( 2) increasing convergence. Firstly,the forward modeling is done,and the inversion is processed with the optimal solution. Compared with classical Tikhonov regularization scheme,the method reflects better resolution and stronger convergence. Then,Marmousi model is experimented and inversed,and the deep structure has a sharper outline. The phase residual comparison illustrates weaker cycle-slipping. And a choice scheme of parameter is applied in FWI. | SUN Ruixue HAN Liguo SUN Eryan | 2015 | Global Geology2015，18，4： | 1 |
| 3 | A novel four-component reaction involving ring-opening/recyclization of 1,3-thiazolidinedione显示文摘The multicomponent reactions of 1,3-thiazolidinedione, malononitrile, aromatic aldehydes and α-phenylethylamine or β-phenylethylamine in acetonitrile at room temperature produce dihydrothiophene ureidoformamide derivatives in moderate yields through a domino ring-opening/recyclization reaction of 1,3-thiazolidinedione. On treatment with DDQ, dihydrothiophenes are dehydrogenated to convert efficiently to thiophenes in the mild condition. | SUN Jing, XIA ErYan, ZHANG LiLi & YAN ChaoGuo College of Chemistry & Chemical Engineering, Yangzhou University, Yangzhou 225002, China | 2010 | Science China Chemistry2010，53，4： | 0 |
