- Abstract:
- ... Drought stress is a serious threat to agriculture and the environment. Brassinosteroids (BRs) increase tolerance to drought stress of plant. Autophagy plays important roles in plant responses to drought stress; however, there are few reports on autophagy in peach (Prunus persica). In total, 23 putative autophagy-related genes (ATGs) in peach were identified using ATGs from the Arabidopsis thaliana ...

- Abstract:
- ... We demonstrate an in situ synthesis for preparing a carbon-shielded three-dimensional Co–Ni nanocone array on Ni foam (CoNi NCs/NF@C) via the solvothermal and thermal annealing processes. It is found that the easily separable CoNi NCs/NF@C possesses high peroxidase/catalase dual-mimic activity and good catalytic stability. The fusion of the amorphous carbon sheath with the Co–Ni nanocones (1) effe ...

- Abstract:
- ... Postharvest surface browning is the leading constraint for extension of shelf life and marketing of litchi fruit. In the present work, litchi fruit were treated with Aloe vera (ALV) gel coating [50% (v/v)] and kept at 20 ± 1 °C for 8 d to investigate its effect on browning and postharvest quality. ALV gel coated fruit showed reduced browning index, weight loss, superoxide anion, relative electroly ...

Results showed that the growth of highland barley (Kunlun 14) and barley (Ganpi 6) had no obvious difference under low concentrations (50, 100 and 200 mM) of NaCl treatment. However, high concentrations of NaCl treatment ( ...

With increasing levels of Al (viz. 100, 200 and 300 μM), the mean length of root, shoot as well as their biomass accumulation decreased linearly with respect to control. Tolerance test of F. kashmirianum revealed that it was more tolerant to Al-stres ...

- ... Arbuscular mycorrhizal (AM) fungi (AMF) are widely known to form a symbiosis with most higher plants and enhance plant adaptation to a series of environmental stresses. Sweet sorghum (Sorghum bicolor (L.) Moench) is considered a promising alternative feedstock for bioalcohol production because of its sugar-rich stalk and high biomass. However, little is known of AMF benefit for biomass production ...

- Abstract:
- ... The growth and yield of peanut are negatively affected by continuous cropping. Arbuscular mycorrhizal fungi (AMF) and calcium ions (Ca2+) have been used to improve stress resistance in other plants, but little is known about their roles in peanut seedling growth under continuous cropping. This study investigated the possible roles of the AMF Glomus mosseae combined with exogenous Ca2+ in improving ...

- Abstract:
- ... Autotoxicity is a common problem being faced in protected vegetable cultivation system. Phytoremediation of plant autotoxicity is an emerging concept to minimize deterioration of soil environment and reduction of yield and quality of vegetable crops. Brassinosteroids (BRs) have been reported as a potential phytohormone to assist phytoremediation. However, the effects of BRs-induced autotoxicity st ...

- Abstract:
- ... Water deficit adversely affects the growth and productivity of annual ryegrass (Lolium multiflorum Lam.). The exogenous application of chitosan (CTS) has gained extensive interests due to its effect on improving drought resistance. This research aimed to determine the role of exogenous CTS on annual ryegrass in response to water stress. Here, we investigated the impact of exogenous CTS on the phys ...

- Abstract:
- ... The aim of this study was to compare the ecotoxicity of nickel (Ni) and zinc (Zn) assayed as single and as binary mixture. In addition, how were affected the population growth rates and oxidative stress biomarkers, comparing single to binary exposures. The toxicity tests were performed on Lemna gibba using a 7-day test. All calculations were made using measured total dissolved metal concentrations ...
