ABSTRACTPlant biostimulants are commercial products based on different chemical substances used to enhance plant growth and productivity. The effects of biostimulants, Megafol and Viva, with different dominant compositions (amino acids and humic acids) on two tomato cultivars (cv. Gravitet F1 and cv. Minaret F1) exposed to conventional and low-input macronutrient nutrition were investigated. Application of both biostimulants positively affected yield at conventional nutrition. In low-input nutrition variant, biostimulant application prevented yield loss only in cv. Minaret F1. Inter-cultivar differences were noticed in fruit characteristics (total phenol content, total flavonoids content and total antioxidative capacity) where application of biostimulants leads to opposite results in the examined cultivars. We considered the possibility of biostimulant usage as an effective nutritional addition for overcoming the problem of excessive fertilisation. 相似文献

Environmental concern due to plant accumulation of natural radionuclides is a major concern in uranium mining areas. To evaluate the risk associated with the transfer of radionuclides to edible plants, the uptake of 238U, 226Ra, and 210Pb by Chinese cabbage (Brassica rapa L. subsp. pekinensis (Lour.) Hanelt) grown in soils contaminated with uranium-mill tailings (UMT) was investigated. Test plants were grown under controlled conditions in substrate composed of soil and UMT in different ratios. Activity concentrations of 238U, 226Ra, and 210Pb in substrate, leaves, and roots were measured and the concentration ratios determined. Soil characteristics were determined, since they directly affect bioavailability of radionuclides. Concentration ratios of 238U, 226Ra, and 210Pb in leaves varied from 0.001 to 0.006, 0.024 to 0.172, and 0.004 to 0.011, respectively, and in roots from 0.020 to 0.126, 0.015 to 0.241, and 0.033 to 1.460, respectively. Concentrations of 238U, 226Ra, and 210Pb in leaves and roots were found to correlate with the amount of 238U, 226Ra, and 210Pb in the substrate. A higher amount of 226Ra accumulated in aboveground parts (57–877 Bq kg?1 d. m. for leaves) compared to 238U (0.6–4.7 Bq kg?1 d. m. for leaves) and 210Pb (8–53 Bq kg?1 d. m. for leaves), which were mainly stored in the roots. The relationships between the amount of radionuclides in plants and soil characteristics and their role in radionuclide uptake are discussed and critically evaluated. 相似文献

A series of experiments were carried out to investigate the colour stability of chemically treated and thermally modified
wood compared to non-modified wood during long term artificial UV light irradiation. One set of wood samples was vacuum-pressure
impregnated with alkaline (pH 9.8) copper (II) ethanolamine aqueous solution, while another set of samples from the same wood
block was thermally modified at 210°C and −0.90 bar for 2 h. The treated and modified wood samples along with the non-modified
ones were exposed to artificial UV light with the wave length in the region of UVA (315–400 nm) and UVB (280–315 nm) intermittently
for 500 h. Colour measurements were carried out throughout the irradiation period at an interval of 100 h according to CIEL*a*b*
system, where the results are presented in terms of ΔE, ΔL*, Δa* and Δb* values. Better photo-stability in terms of colour changes was recorded for both treated and modified woods compared to the
non-modified one. By means of EPR and DRIFT spectroscopic study it was shown that some degree of colour stability of treated
and modified woods, achieved during artificial UV light irradiation, resulted from lignin modifications and monomers of phenolic
compounds. 相似文献

The collection, identification and maintenance of genebank accessions of the genus Trifolium is a major task because of the large number of genera and their occasional morphological similarity. We investigated whether
the measurement of nuclear DNA content can serve as an additional criterion for identification of mislabeled accessions. Relative
nuclear DNA content was determined by flow cytometry measurements for a total of 151 genebank accessions of 23 Trifolium species with notable agronomical value. Among 23 species analyzed, 15 were found to possess a uniform relative nuclear DNA
content, with intraspecific variability of the majority of analyzed species lower than 5%. Within six Trifolium species, 1–2 atypical accessions with outstanding differences in relative DNA content, chromosome number and morphological
features were found. In T. hybridum and partially in T. ambiguum these outstanding differences could be ascribed to variations in accession ploidy level. For the remaining atypical accessions,
the determined nuclear DNA content, chromosome number and morphological features were not related to those characteristic
of the species. Additionally taxonomic identity of atypical accessions was determined using ITS region sequencing and morphological
observations. We propose flow cytometric measurements of nuclear DNA content as simple and reliable technique which can be
used at seedling stage to verify identity and genetic stability of Trifolium genebank accessions. 相似文献

Haemaphysalis cretica and H. otophila thrive in the Mediterranean phytogeographic zone of the eastern Mediterranean area. Haemaphysalis otophila has a wide geographical distribution, H. cretica is more restricted.The adults of both species parasitize sheep and goats, and transmit diseases. The pre-imaginal stages feed on reptiles and small mammals. Adults attach to their hosts only during winter. The pre-oviposition period is long and the embryonic development is slow. Larvae hatch in spring and attach to their hosts in early summer; nymphs follow somewhat later and descend off their hosts in late summer. There is only one generation per year for each of the species. 相似文献

This paper presents a system for supporting agricultural subsidies in Slovenia. First, an overview is given of specific areas of Slovenia’s land, considered as zones. Then, the system, which explores the computational power of today’s clients is briefly introduced. Some features of the geometric and topological system (GTS), is introduced. This application has been used successfully for 3 years and has turned out to be effective and stable. 相似文献
