In the past, chiral pesticides were explored as racemic mixtures in environmental fate and ecotoxicities. However, as a result of the enantioselective interactions with chiral molecules, the enantiomers of chiral pesticides may have different potential toxicities to humans and animals. The present r...

The binding of acetochor, pretilachor, butachlor and metolachlor to urease in aqueous solution was studied using UV difference spectrum and fluorescence spectrum methods. According to the UV difference spectrum curve obtained, the UV difference adsorption AA showed rapid change when herbicide concen...

The accelerated promotion of new urbanization has brought about population mobility, which has placed greater pressure on megacities in terms of inter-regional competition for high-quality resources in compulsory education and their carrying capacity. To achieve high-quality and balanced development...

Approaches to the chromatographic (GC, HPLC, CE, SFC and TLC) enantiomer separation and determination of chiral contaminates are reviewed. The enanriomers of chiral contaminates are selectively degradation and interaction in soil and water environment. For the separation and determination of main ty...

Abstract: Understanding the waxy maize starch physicochemical properties response to heat stress during grain filling could improve starch quality. The effects of heat stress during early (1–15 days after pollination, DAP) and late (16–30 DAP) grain filling stages on the starch physicochemical prope...

The enantioselective inclusion interaction of various cyclodextrins (β-CD, PM-β-CD, CM-β-CD) with R/S-2, 4-dichlorprop methyl ester (R/S-2, 4-D) was studied by UV spectra technique. The results show that all cyclodextrins formed 1∶1 inclusion complexes with 2, 4-D, the order of binding constants of...

Excessive or insufficient application of fertilizer has raised broader concerns regarding soil and environmental degradation. One-time application of slow release fertilizer (SF) has been widely used to reduce yield gap with potential maize yield and improve nitrogen use efficiency (NUE). A 2-year f...

Optimal planting density and proper fertilization method are important factors to improve maize yield and nutrient utilization. A two-year (2016 and 2017) field experiment was conducted with three plant densities (6.0, 7.5 and 9.0 plants m–2) and three fertilization modes (no fertilizer, 0F; one-off...

Waxy maize is widely cultivated under rainfed conditions and frequently suffers water shortage during the late growth stage. In this study, a pot trial was conducted to examine the effects of post-silking drought on leaf photosynthesis and senescence and its influence on grain yield. Two waxy maize...

Post-silking high temperature is one of the abiotic factors that affects waxy maize (Zea mays L. sinensis Kulesh) growth in southern China. We conducted a pot trial in 2016–2017 to study the effects of post-silking daytime heat stress (35°C) on the activities of enzymes involved in leaf carbon and n...

Grain physicochemical properties determine the table quality of fresh waxy maize. Two waxy maize varieties, Suyunuo 5 (shading tolerant) and FHN003 (shading sensitive), were used to estimate the effect of shading (plants received 30% less radiation than control) during grain filling (from 0 d to 23...

Upland cotton (Gossypium hirsutum L.) is the most important natural textile fiber crop worldwide. Plant height (PH) is a significant component of plant architecture, strongly influencing crop cultivation patterns, overall yield, and economic coefficient. However, cotton genes regulating plant height...

The differences between uptake and utilization of soil K by two lowland rice genotypes differed in the tolerance to low K were studied by rhizobox cultivation. The results showed that the growth of aerial part of Fujiandao, a rice genotype tolerant to low K, was not obviously affected by low K stres...

A simple and highly efficient catalytic system for the selective aerobic oxidative ring-opening of substituted furans has been achieved using Fe(NO3)3·9H2O as a catalyst and air as an oxidant under mild conditions. A series of (Z)-1,4-enediones were obtained in good yields (up to 97 %) with excellen...

Isolated male epispadias typically presents with preputial defects and dorsal urethral dehiscence. A less common subtype, known as concealed epispadias, is distinguished by an intact prepuce. Despite its clinical relevance, there is limited literature on this variant. In this study, we retrospective...
