Responses of Phosphorus Use Efficiency, Grain Yield, and Quality to Phosphorus Application Amount of Weak-Gluten Wheat

引用

Journal of Integrative Agriculture 2012年第7期11卷 1103-1110页

作者： ZHU Xin-kai LI Chun-yan jiang Zong-qing huang Lian-lian FENG Chao-nian GUO Wen-shan PENG Yong-xin Key Laboratory of Crop Genetics and Physiology Jiangsu Province/Wheat Research Institute Yangzhou University Yangzhou 225009P. R. China

Phosphorus （P） is one of the most widely occurring nutrients for development and growth of wheat. In this study, the effects of P application amount on grain yield, protein content, and phosphorus use efficiency （PUE） were studied by agronomic management of P fertilizer on spring weak-gluten wheat （Triticum aestivum L.） grown under field conditions for 2 yr. The experiments were performed at five levels of P205 application amount, including 0, 72, 108, 144, and 180 kg ha-1. As a result, with increase in P fertilizer, grain yield, and P agricultural efficiency （AEp） increased in a quadratic equitation, but partial factor productivity of P （PFPp） decreased in a logarithmic eq. When 108 kg ha-1 P2Os was applied, the grain yield reached the highest level, but the protein content in gain was lower than 11.5%, a threshold for the protein content to evaluate weak-gluten wheat suitable for production of cake and biscuit. Yangmai 13 and Ningmai 9 could tolerate to higher P level of soils than Yangmai 9 that had more loss in grain yield when P fertilizer was over-applied. AEp had a concomitant relationship with grain yield and was a better descriptor for P use efficiency in the wheat. A high P use efficiency resulted in leaf area index （LAI）, increased chlorophyll content and photosynthetic rate, and stable acid phophatase （APase） activity to accumulate more dry matter after anthesis, which explained that the optimum P fertilizer increased grain yield and improved grain quality of weak-gluten wheat.

A Case on Acute Burkholderia pseudomallei Pericarditis

Chinese Medical Journal 2016年第18期129卷 2256-2257页

作者： Xing-Jun Cai Yi-jiang huang Yi-Hui Fu Department of Respiratory Hainan General Hospital Haikou Hainan 570311 China

Melioidosis is an endemic communicable disease caused by Burkholderia pseudomallei and a prevalent amphixenosis in tropical and subtropical regions. The main routes of infection are thought to be through compromised surface tissues and through inhalation of contaminated soil and water. B. pseudomallei can affect all organs, but pulmonary infection is the most common symptom, which could easily lead to sepsisYl Here, we reported what we believe is a rare case of acute pericarditis caused by B. pseudomallei infection.

Studies on Cyclodextrin Inclusion Complex by Fluorescence Anisotropy

引用

Chemical Research in Chinese Universities 1990年第4期6卷 327-331页

作者： jiang Yunbao, huang Xianzhi and Chen Guozhen (Department of Chemistry, Xiamen University, Xiamen)

An equation for determining the equilibrium association constant (KA) of cyclodextrin inclusion complex with fluorescence anisotropy is derived and used to determine KA of pyrene-B-cyclodextrin inclusion complex. The existing forms of cyclodextrin inclusion complex in solution, the interaction type of host with guest, and the possibility of application of B-cyclodextrin in the analysis of metal ions using naphthalene derivative as a ligand are discussed based on the equation derived along with the curve of fluorescence anisotropy versus cyclodextrin concentration of guest/cyclodextrin system.

THE SYNTHESIS AND STRUCTURE OF Mo3（μ3-O）(μ-S)3（μ-O2CC6H5）2（dtp）2（Py）

引用

Chinese Journal of Structural Chemistry 1992年第4期 253-256页

作者： Wang Zhe-Min Zhang Bin huang Wen huang jiang-Quan huang Jin-LingDepartment of Chemistry , Fuzhou University, Fuzhou, Fujian, 350002, China

The title compound was prepared by reaction of Mo3(μ3-O) (μ-S)3-(dtp)4 (H2O) with C6H5COONa and pyridine. C27 H35 Mo3NO9P2S7, Mr = 1091.76, monoclinic, space group P21/c, a = 15. 057(5), b = 13. 052(5), c = 21. 662(6)(?), β=105.97(2)°, V = 4093(2) (?)3, Z = 4, Dc= 1. 77gcm-3, F(000) = 2176, μ(MoKα)=13.50cm-1, final R =0. 068 for 2835 observations. The molecular configuration is new and of approximate C, symmetry, and there are two C6H5COO bridging groups in the structure. The three Mo atoms form an isosceles triangle with three sides of 2. 567(3), 2. 576(3), and 2. 649(3)(?), where the two Mo-Mo bonds bridged by C6H5COO group are much shorter than that without. Something about the reactivity of Mo clusters is discussed.
