In the present study, free amino acid (AA) regulation in the arsenic (As) hyperaccumulating ferns was evaluated in a pot experiment to determine the relationship between As stress and the characteristic change in metabolism of AAs. The ferns Pteris cretica cv. Albo-lineata (Pc-Al) and cv. Parkerii (Pc-Pa) were exposed to As treatments at 0, 20, 100, and 250 mg As/kg for 90 days. Greater As content, as well as higher biomass production, were identified in Pc-Al compared with Pc-Pa. Ferns showed changes in the stress metabolism of free AA homeostasis. These results indicate a disturbance in nitrogen metabolism and depletion of pool assimilated...

Consecutive monocropping with sanqi (Panax notoginseng (Burkill) F.H. Chen) can increase the abundances of pathogens in soil, resulting in soil sickness. Crop rotation is one way to alleviate this problem. In the present study, there were no differences in microbial structure or bacterial alpha diversity among one-year monocropping soil, one-year rotation soil, and ten-year rotation soil. However, monocropping practices decreased fungal alpha diversity. The relative abundance of copiotrophic bacteria decreased after sanqi monocropping, while that of oligotrophic bacteria increased. Ten-year rotation significantly increased the abundance of...

The study presents results of 4-year field trials; their purpose was to assess the effectiveness indices of phosphorus recovery in maize cultivation depending on the depth of two-component fertiliser (NP) placement in the soil layer, type of nitrogen fertiliser (ammonium nitrate and urea) and time point of the application. The hypothesis of the experiment assumed that different depth of NP fertiliser placement improved the indices of phosphorus application in maize cultivation. Row fertilisation with two-component NP fertiliser, regardless of the year, clearly affected phosphorus accumulation (uptake) with grain yield. The recovery metabolism index,...

Phosphorus (P) in soils occurs predominately as insoluble inorganic P and organic P. However, key factors controlling P acquisition by wheat (Triticum aestivum L.) seedlings are unclear. In this study, the difference in the physiological characteristics of P acquisition in alkaline soils was investigated in wheat seedlings of two cultivars Aikang 58 and Zhoumai 22. The results indicated that the shoot P concentration of Aikang 58 was significantly higher than that of Zhoumai 22 when supplied with 0 and 70 kg/ha of pure P under field conditions. When cultured in sterile nutrition solutions with equimolar...

This study aimed to evaluate the effect of different slurry volume of imidacloprid insecticide on the physiological potential during the storage of seeds of three soybean cultivars. A completely randomised experimental design was adopted, in a 6 × 3 × 2 factorial scheme, which treatments were six slurry volumes with imidacloprid insecticide (0, 200, 500, 800, 1 100 and 1 400 mL/100 kg of seeds), 3 soybean cultivars (SYN15630, M5947, and NS5959) and 2 storage periods (0 and 30 days after seed treatment), with four replications. The treated seeds were stored in kraft paper bags with controlled temperature and humidity. The physiological potential of...

The influence of four main weather attributes on the content of alpha-acids of the hop cv. Aurora for the period 1994-2019 was studied. By analysing correlation coefficients, specific times of the year when the weather conditions affect the alpha-acid content with the goal of creating a forecasting model in Slovenia were identified. The most significant periods of weather that impacted the alpha-acid contents throughout the growing time of year are recognised as attributes of temperatures (T), rainfall (R) and sunshine (S) calculated from the 25th to 30th...

The presence of Epichloë endophyte can promote plant growth and increase the accumulation of host plant nutrients. We determined the dry matter (DM) and important nutritional indicators of E+ (infected by endophyte) and E- (not infected by endophyte) Festuca sinensis under the three-time repeated cutting. The results indicated that the total nitrogen, total phosphorus, crude protein (CP), crude fat (CF), crude ash (CA)...

Salinity is one of the most widespread stresses responsible for water and soil pollution across the globe. Salicylic acid (SA) has a major role in defence responses against various abiotic stresses. In the current study, SA (0.05 mmol) influences were evaluated in mitigation of the negative impact of salinity (40 and 80 mmol NaCl) in the maize plant. NaCl stress-induced significant accumulation of organic osmolytes (total soluble sugars (TSS), total soluble protein (TSP), and proline) by 35.6, 66.2, and 89.2%, respectively, with 80 mmol NaCl. In addition, salinity is also responsible for the elevated accumulation of inorganic osmolytes (Na
