Light plays a key role in net primary productivity. To take full advantage of light interception and Radiation Use Efficiency (RUE) in maize, Reasonable planting densities should be suggested for different varieties to achieve optimal growth conditions in North-Eastern China. This study was performed in 2009, 2010 and 2011 at one of the CAAS North-East Research Stations. The experiment was conducted using a split-plot design based on a randomised complete block design with three replicates; treatments included planting densities of 37, 500, 52, 500, 67, 500 and 82, 500 plants per hectare (pi ha"1) and 10 varieties were used as sub-treatments. We examined RUE values in different types (spreading leaf, intermediate type, upright leaf) and varieties and identified reasonable densities for different types in relation to the light distribution in North-Eastern China to achieve the highest RUE. All treatments showed significant effects of interception, RUE and density. Ideal planting density differed among types in combination with local light resources. In conclusion, the best densities for spreading-leaf, intermediate and upright-leaf types were 33, 381-41, 736 pi ha"1, 44, 629-56, 584 pi ha"1 and 62, 573-82, 969 pi ha"1, respectively, in North-Eastern China. Maximum grain yield should be realised when maize is grown at the optimum plant density for dry matter yield. © 2013 Asian Network for Scientific Information.

A simulation study was focused on the phase separation of binary ligands coated on the nanoparticle via the dissipative particle dynamics. After comparing with available simulation and experimental works in literatures, the results support the viewpoint that the driving force comes from the conformational entropy arisen due to a mismatch of ligand chains. A further investigation is conducted on the self-assembly of Janus or triblock Janus nanoparticles in selective solvents. The simulations show that the Janus particles tend to assemble into double-layered vesicle structure, while the triblock Janus particles can form single-layered vesicle structure. This study supplies the theoretical guideline for the design of functional vesicle material via the polymer coated nanoparticles. © 2016, Higher Education Press. All right reserved.

CoxNi1-xFe2O4 (x=0~1) nanoparticles were synthesized by hydrothermal method. And then X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and magnetic scanning magnetometer were used to characterize the structural, morphological and magnetic properties. XRD results indicate the lattice constant of CoxMn1-xFe2O4 decreases with increasing Co2+ substitution. Magnetic measurements show that all the samples are ferromagnetic at room temperature, and magnetization and coercivities of the samples increase with Co2+ substitution. ©, 2014, Editorial Office of Semiconductor Optoelectronics.

This paper introduces a tripeptide (β-Asp-Phe-Phe, abbreviation β-AspFF) which can self-assemble into long nanofibrils in toluene solvent and further entangle to organogels. The nanofibrils of β-AspFF can serves as ligands to incorporate with Co(II) in the organogels. After being re-immersed into HFIP-H2O mixed solution (Volume Ratio, 1:1), the β-AspFF-Co(II) xerogel exhibited decent oxygen binding properties. Impressively, in comparing with β-AspFF-Co(II) complex, the β-AspFF-Co(II) xerogel proved to be a higher efficient catalyst for catalyzing cyclohexene oxidation reaction. We therefore suppose that the porous and nanofibrils structure of the xerogel plays a key role to improve the catalytic behavior of β-AspFF-Co(II) complex. © 2016 Elsevier B.V.

In this paper, we selected histidine-Co(II) complex as the target for researching its good oxygenation performance, and obtained short peptide, pseudo peptide and histamine through masking -NH3 +, replacing -O- and removing -COO-, respectively. The impacts of three functional groups in α-amino acids on the oxygenation performance of their Co(II) complexes were investigated via UV-Vis spectrophotometry. The comparative study showed that in α-amino acids, the -NH3 + group plays a decisive role in oxygenation properties, -COO- group plays a key role in reversibility of oxygenation, and -O- has little influence on absorbing oxygen of complexes. The mechanism of α-amino acid-Co(II) complexes reversible absorbing and releasing O2 are discussed on the basis of previous research results. © 2016, Higher Education Press. All right reserved.

Wild Rosa species, which are highly variable and locally adapted, are widely distributed in the Xinjiang Uygur autonomous region of China. These species possess many important horticultural traits that are not found in the gene pool of modern cultivated roses. However, little is known about their cytological characteristics, because few of them have been karyologically analyzed. Karyological data of 13 samples of seven wild Rosa taxa, including R. berberifolia, two botanical varieties of R. spinosissima, R. platyacantha, R. beggeriana, R. acicularis, and R. laxa, were investigated by means of squashes of shoot tips. The results showed that seven samples were diploid (2n = 2× = 14), whereas the other six samples were tetraploid (2n = 4× = 28). The karyotypes of all the test samples were composed ofmand sm chromosomes, which include 1A, 2A, 1B, and 2B. There were differences in asymmetry index, centromere index, and distribution of relative lengths. The karyotype of the tetraploid R. laxa var. laxa sample from Aksu easily distinguished from the other R. laxa var. laxa samples tested in having the highest asymmetry index and the most evolved karyotype. This Aksu population merits recognition as a new botanical variety of R. laxa. The karyological data, most of which are first reports for their taxa, provide a comprehensive cytogenetic resource that can be used to better understand the taxonomy, evolution, and speciation in the genus Rosa and to identify candidate species for breeding programs.
