Phosphorus supply and management in vegetable production systems in China

Rui WANG, Weiming SHI, Yilin LI

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 4,   Pages 348-356 doi: 10.15302/J-FASE-2019277

Abstract:

Vegetable production systems involve high rates of chemical and organic fertilizer applications, leadingto significant P accumulation in vegetable soils, as well as a decrease in P use efficiency (PUE), whichis one of the key limiting factors in vegetable production.This review introduces the vegetable production systems in China and their fertilization status, andanalyzes probable causes of overfertilization of vegetable fields.

High cadmium pollution risk on vegetable amaranth and a selection for pollution-safe cultivars to lower

Yihui ZHOU, Meng XUE, Zhongyi YANG, Yulian GONG, Jiangang YUAN, Chunyan ZHOU, Baifei HUANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 2,   Pages 219-230 doi: 10.1007/s11783-012-0469-9

Abstract: A pot experiment was carried out by growing 29 different genotypes ( spp.) of vegetable amaranth underThe results indicated that amaranth is capable of enduring high level of Cd pollution when grown as vegetablecrop, and accordingly, consuming vegetable amaranth would bring high health risk.

Synthesis and characterization of castor oil-based polymeric surfactants

Xujuan HUANG,He LIU,Shibin SHANG,Zhaosheng CAI,Jie SONG,Zhanqian SONG

Frontiers of Agricultural Science and Engineering 2016, Volume 3, Issue 1,   Pages 46-54 doi: 10.15302/J-FASE-2016083

Abstract: Dehydrated castor oil was epoxidized using phosphoric acid as a catalyst and acetic acid peroxide as an oxidant to produce epoxidized castor oil (ECO). Ring-opening polymerization with stannic chloride was used to produce polymerized ECO (PECO), and sodium hydroxide used to give hydrolyzed PECO (HPECO). The HPECO was characterized by Fourier transform infrared, H and C nuclear magnetic resonance spectroscopies, gel permeation chromatography, and differential scanning calorimetry. The weight-average molecular weight of soluble PECO and HPECO were 5026 and 2274 g·mol , respectively. PECO and HPECO exhibited glass transition. Through neutralizing the carboxylic acid of HPECO with different counterions, castor oil-based polymeric surfactants (HPECO-M, where M= Na , K or triethanolamine ion) exhibited high efficiency to reduce the surface tension of water. The critical micelle concentration (CMC) values of HPECO-M ranged from 0.042 to 0.098 g·L and the minimum equilibrium surface tensions at CMC ( ) of HPECO-M ranged from 25.6 to 30.0 mN·m . The water-hexadecane interfacial energy was calculated from measured surface tension using harmonic and geometric mean methods. Measured values of water-hexadecane interfacial tension agreed well with those calculated using the harmonic and geometric mean methods.

Genetic Manipulation of Non-Classic Oilseed Plants for Enhancement of Their Potential as a Biofactory for Triacylglycerol Production Review

Xiao-Yu Xu,Hong-Kun Yang,Surinder P. Singh,Peter J. Sharp,Qing Liu

Engineering 2018, Volume 4, Issue 4,   Pages 523-533 doi: 10.1016/j.eng.2018.07.002

Abstract:

Global demand for vegetable oil is anticipated to double by 2030.The current vegetable oil production platforms, including oil palm and temperate oilseeds, are unlikelyTherefore, the exploration of novel vegetable oil sources has become increasingly important in orderto make up this future vegetable oil shortfall.Triacylglycerol (TAG), as the dominant form of vegetable oil, has recently attracted immense interest
