A hydroponic experiment was carried out to study the ameliorative effects of exogenous glycinebetaine (GB) upon cadmium (Cd) toxicity in cucumber seedlings. The results indicated that 50 μmol/L Cd stress decreased soil plant analysis development (SPAD) value, plant height, root length, seedling biomass, activities of ascorbate peroxidase (APX) and ATPase in leaves, stems and roots; however, increased peroxidase (POD) and superoxide dismutase (SOD) activities in all tissues, catalase (CAT) activities in stems/roots. Moreover, Cd stress also elevated leaf/root malondialdehyde (MDA), proline, phenols and flavonoid content in all cucumber tissues over...

With the need to obtain new methods to protect seed material from Ditylenchus dipsaci (Kühn, 1857) nematodes, a study was conducted to evaluate the nematicidal effects of several plants' essential oils on the mortality of D. dipsaci. Tests were performed under in vitro conditions; a concentration of 2 000 ppm was tested, nematodes were added into diluted oils, and numbers of living/dead nematodes were scored after 4 and 24 h. The results show a significant effect of several plant essential oils on D. dipsaci mortality, with the highest efficacy found for oil from Cinnamomum cassia ((L.) J. Presl), with 100%...

The concept of terroir relates the sensory attributes of wines attributable to the environmental conditions of the grapevines, and therefore it represents an important descriptor of the connection between wines and their origins. In ongoing efforts to improve the monitoring and geochemical fingerprinting of grapevine products, knowledge of the variability of grapevine elemental compositions, and factors that have strong influences on this, can significantly improve the traceability of wines to their origins. Here, we demonstrate a strong connection of grapevine elemental composition to the micro-location of the individual vineyard, with an...

Urease inhibitor and biochar independently affected N2O emissions from Camellia oleifera soilsOriginal Paper

Nitrous oxide (N2O) is a long-lived greenhouse gas that impacts climate change. Agricultural soils with intensive nitrogen (N) application are the main source of N2O emissions. Reducing N2O emissions from N-fertilised soils is, therefore, important for climate change mitigation. The application of urease inhibitor and/or biochar provides the potential for mitigating N2O emissions. However, the interactive effect of urease inhibitor and biochar on N2O emissions remains limited. In this study, an incubation experiment was performed to investigate the gradients of urease inhibitor N-(n-butyl) thiophosphoric triamide (NBPT) (0, 0.08, 0.16, and 0.24%) and...

Four different rapeseed (Brassica napus L.) cultivars CZL, Benefit, Iwas and ZhongZhuang9, were used to analyse physiological responses to higher doses of cadmium (Cd) and their ability of Cd accumulation. Plants were exposed for 30 days to different Cd dosages (0, 50, 100, and 150 mg Cd/kg) in soil under greenhouse conditions. Cadmium was accumulated more in roots than in shoots of all tested cultivars, with the highest Cd in ZhongZhuang9. After the lowest Cd dose, the highest translocation factor was for CZL (0.8) and Benefit (0.6). The content of both K and Ca varied between treatments and cultivars. The chlorophyll fluorescence parameters and relative...
