An experimental site for the measurement of meteorological parameters in protected environment and the evaluation of the tomato cultivar variability is presented in this paper. The site was equipped with cultivation structures with different covering materials and calibrated sensors traceable to the International System of Units. The microclimate conditions were monitored by sensors for solar radiation (from 290 nm to 2800 nm), air temperature (from -10°C to 40°C) and relative humidity (from 10% RH to 98% RH) inside and outside the tunnels. Specific procedures were used to calibrate the instruments. The following aspects were evaluated: microclimate...

Several sets of soil samples were chosen to demonstrate the applicability of the Mehlich 3 extractant for the determination of sulphur (S) in soils. Archived samples from 139 basal soil monitoring plots (BSMS) sampled in 1995 and 2013, samples from eleven long-term field trials sampled in 1981 and 2017, 1167 soil samples from the areas vulnerable to S losses and 720 samples from the non-vulnerable areas sampled in 2010 were chosen for the experiments. Mehlich 3 clearly showed a statistically highly significant decrease in the soil S content caused by reduction of SO2 emissions in the long-term field...

Determining the effects of progressive drought (PD) on dry matter production, partitioning, and grain yield of maize will help in designing a suitable strategy for water management. Though influences of drought on maize growth and development have been investigated extensively, few of them focused on the effects of different duration and occurrence stage of PD on yield formation of maize. Six variations of PD, in the form of withholding irrigation for varying lengths of time from jointing or tasselling, were tested in the field, using a mobile rain shelter, in terms of their effects on aboveground biomass accumulation, partitioning, and grain yield...

Plant composition, herbage yield, and nitrogen objectives in Arrhenatherion grasslands affected by cattle slurry applicationOriginal Paper

Plant Soil Environ., 2018, 64(6):268-275 | DOI: 10.17221/178/2018-PSE  

Cattle slurry is commonly used to fertilize grasslands, so its impact on plant composition and herbage properties is important. Cattle slurry at annual rates of 60 (S1), 120 (S2), 180 (S3), and 240 kg nitrogen (N)/ha (S4) was applied to Arrhenatherion grasslands in moderately wet (WS), slopy (SS), and moderately dry (DS) sites cut three times a year over six years, to assess its effects on plant functional types, the Ellenberg N indicator value (Ellenberg N), herbage dry matter (DM) yield, herbage N content and offtake, N nutrition index (NNI), and N use efficiency (NUE). The site-specific changes in an increase in graminoid cover, Ellenberg...

Spectral data contain information on soil organic and mineral composition, which can be useful for soil quality monitoring. The objective of research was to evaluate hyperspectral visible and near infrared reflectance (VNIR) spectroscopy for field-scale prediction of soil properties and assessment of factors affecting soil spectra. Two hundred soil samples taken from the experiment field (soil depth: 30 cm; sampling grid: 15 × 15 m) were scanned using portable spectroradiometer (350-1050 nm) to identify spectral differences of soil treated with ten different rates of mineral nitrogen (N) fertilizer (0-300 kg N/ha). Principal component analysis revealed...

Tea plants grown in acidic soils are strongly dependent on arbuscular mycorrhizas, whereas it is not clear whether soil arbuscular mycorrhizal fungi (AMF) improve plant growth, root development, and nutrient absorption in tea plants. A potted study was conducted to determine the effects of Claroideoglomus etunicatum, Diversispora spurca, D. versiformis and a mixture of the three AMF species on plant growth, root morphology, root-hair growth, and leaf nutrient status in Camellia sinensis cv. Fuding Dabaicha in Jingzhou, China. After 12 weeks of AMF inoculation, root mycorrhizal colonization ranged...

The first genistin absorption screening into vacuoles of Trifolium pratense L.Original Paper

Plant Soil Environ., 2018, 64(6):290-296 | DOI: 10.17221/134/2018-PSE  

The determination of a transport mechanism for genistin (genistein-7-O-glucoside) across the tonoplast was performed on vacuoles from a cell culture of Trifolium pratense L. Genistin levels were examined in vacuoles as well as in an assay medium by HPLC (high-performance liquid chromatography) after treatment with various substances. MgATP increased the uptake of added genistin by 25%, but the nucleotide-free samples also contained this glycoside. Applying bafilomycin A1, an H+-ATPase inhibitor, indistinctly inhibited genistin absorption. However, vacuolar absorption of genistin was...
