The study focused on the effects of gap size on natural regeneration of European beech (Fagus sylvatica L.) and Norway spruce (Picea abies L.) and micro-environmental soil conditions in gaps of different sizes under temperate mixed forest in the Czech Republic. Six gaps comprising two for small (≥ 200 m2), medium (≥ 500 m2) and big (≥ 900 m2) each were selected. Ten circular 1 m2 subsampling plots were established at 2 m intervals...

The paper presents the effect of planting density and row spacing on the growth, development and yield of soybean, cv. Merlin, under very diversified thermal and humidity conditions in the north-central part of Poland. The field experiment was performed in 2016-2019. Three planting densities were applied (70, 90 and 110 seeds per 1 m2) with two row spacing (16 and 32 cm), in 4 replications. Under good humidity and thermal conditions in 2016 and 2017, the yield of seeds and protein in soybean was 3.3 times higher than if exposed to extreme drought and accompanying high air temperatures in 2018 and 2019....

This study aimed to evaluate the effect of an arbuscular mycorrhizal fungus (AMF) Glomus mosseae on plant growth, root architecture, and proline metabolism in roots of peach (Prunes persica L.) under non-flooding and flooding conditions. The 12-day flooding dramatically inhibited root colonisation of G. mosseae, but induced a large number of extraradical mycelia. Although the flooding treatment also relatively inhibited growth and root architecture of peach, the mycorrhizal fungal inoculation dramatically increased shoot and root biomass, plant height, stem diameter, number of 1st-...

This study attempted to evaluate the efficiency of zeolite and pyrophyllite ore materials in reducing the mobility of heavy metals in soil near the lignite mining dumps, and consequently in their availability for plants. Extraction of pseudo-total and available forms of heavy metals from soil samples was performed by using aqua regia and ethylenediaminetetraacetic acid, respectively. Concentrations of heavy metals in soil and plant samples were determined by atomic absorption spectrophotometry. The results of this study illustrate that application of zeolite and pyrophyllite could be a suitable technique to...

The Songnen Plain is an important agricultural base in China and one of the important areas of distribution of saline-alkaline soils in the cold region. Saline-alkaline soils severely restrict maize growth. This study was to potentially promote the soil nutrient in the maize rhizosphere, microbes diversity, and maize yield by Trichoderma asperellum in saline-alkaline soil of the cold region. In the present study, we applied different amounts of T. asperellum in field experiments for three consecutive years. High-throughput sequencing was used to analyse the impact of Trichoderma on microbes diversity in maize rhizosphere...

Flowering Chinese cabbages are widely planted in the south of China and often exposed to acid rain. However, the effect of acid rain on the growth of flowering Chinese cabbage is unclear. In this study, we investigated the influence of simulated acid rain (SAR) on plant height, soil-plant analysis development (SPAD) value (an index for chlorophyll content), proline, malondialdehyde (MDA), antioxidant enzyme activities, nitrogen (N), phosphorus (P), or potassium (K) uptake and variation of soil nutrients. Our results showed that SAR at pH 5.5 did not damage plant development because growth characteristics, photosynthesis, and superoxide dismutase and...

Czech hop cultivars were evaluated from 2010 to 2019. A total of 13 cultivars were assessed. The highest yield per plant was found out in cv. Kazbek (3.66 kg/plant), whereas the lowest in cv. Saazer (2.02 kg/plant). Rubín and Boomerang are the cultivars with the lowest variability of the yield per plant. On the contrary, the highest variability was shown by cv. Kazbek. Conclusively the highest content of alpha acids was recorded in cv. Gaia (13.81%), whereas Saazer is the cultivar with the lowest content (2.87%). Significantly highest content of beta acids were recorded in cvs. Gaia, Vital, Boomerang and Bohemie. On the contrary, the lowest content...
