Methodology of analysis of biomass potential using GIS in the Czech Republic

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis (2014)

Kamila Havlíčková Jan Weger J. Šedivá

This article deals with the issue of a methodology for and analyzing biomass potential in the Czech Republic using a geographic information system.The biomass sources considered include cereal and rape straw, permanent grasslands and forest residuals.The process of assessing biomass potential from agricultural soils is based on assigning yields of individual biomass sources according to the production soil-ecological units (BPEJ) which were created for better agricultural planning in the Czech and Slovak Republics.The analysis of energy crop suitability is based on the evaluation of crop yields related to individual BPEJ's respectively to its component the main soil climate units (HPKJ).To ascertain the production potential of residual biomass (straw) from conventional agriculture, the wheat (grain) yield related to HPKJ was multiplied by the straw coeffi cient.The yield of the permanent grasslands in the main soil climate units was also multiplied by the coeffi cient of dry matter.The me thodo lo gy for the analysis of biomass potential for forest land is based on forest management plans that describe the composition of all forest stands.Data from these forest management plans can be used to determine in detail the potential of the forest biomass in individual periods according to the plan for silvacultural treatment and major harvest of the wood.This detailed analysis is suitable only on the municipality level.On a higher government level, the forest management plan can be used to calculate a coeffi cient that determines the average yield from biomass in the form of forest residuals and in relation to the forest size for specifi c areas or levels of analysis.The energy potential of residual biomass is around 136 PJ from present area of conventional agriculture in the Czech Republic.Biomass consumption in animal production and harvest loses were deducted from this calculation.biomass potential, soil-ecological units, forest residuals, permanent grasslands, straw

In Vitro and Ex Vitro Screening of Pea Pisumsativum (L.) Genotypes to Select Osmotic Stress Marker Genes Pscat1, Psdreb1, Psdreb2 and Pslea2

Iva Smýkalová J. Šedivá Marie Greplová Lucie Vaculná J. Horáček

Genetic resources of pea (Pisum sativum L.) were used for screening of tolerance to osmotic stresses. Effective selection marker genes under in vitro osmotic stress simulating by of PEG6000 and NaCl were studied. A hydroponic system was also used for comparison of changes in morphology and growth of multiple shoot cultures (MSC) of 22 pea genotypes. The expression patterns of the candidate marker genes PsCAT1, PsDREB1, PsDREB2 and PsLEA2 in two combined treatments, PEG6000 with NaCl or Zn, were evaluated. The PsLEA2 gene was proposed as a selection marker for tolerant genotypes in both systems. There was also decreased expression of the PsCAT1 gene in both combined treatments in in vitro. Zinc alleviates the stress response, especially reduces necroses and growth inhibition compared to the treatment PEG + NaCl (where Zn uptake was also significantly reduced). We consider genotypes with high expression of the PsLEA2 gene, higher expression of the PsDREB1, PsDREB2 genes and reduced or unaffected expression of the PsCAT1 gene to be tolerant genotypes. On the contrary, the sensitive genotype P13 (P. sativum var. fulvum) reduced expression of all marker genes. According to the winter type of pea cv. Balltrap and drought tolerant W3 and W5 genotypes were select as tolerant the P. sativum ssp. elatius (P2), P. sativum var. balticum (P9) and var. mesomelan (P11) genotypes. In P2 genotype tolerance was only associated with low expression of the PsCAT1 gene. Tolerant genotypes can be used in pea breeding to introduce genes for tolerance to osmotic stress.

Micropropagation as a Tool for the Conservation of Autochthonous Sorbus Species of Czechia

Plants (2023)

J. Šedivá Jiří Velebil D. Zahradník

Members of the genus Sorbus are the only endemic tree species that occur in Czechia. They are important components of endangered plant communities. Their natural regeneration is usually problematic because of their mode of reproduction and because they can survive in rare populations with small numbers of individuals. The aim of this study was to develop a successful micropropagation protocol for selected Sorbus species, of which two are endemic (S. gemella and S. omissa) and two are hybrid (S. × abscondita and S. × kitaibeliana). We found significant differences in shoot induction and rooting ability between the Sorbus species under study. With the exception of S. × abscondita, N6-benzyladenine had a significantly greater effect on shoot regeneration, both in terms of shoot number and total shoot length, than meta-topolin. Root induction was key to the successful micropropagation of the Sorbus species studied. Our results show that four Sorbus species can be successfully rooted under ex vitro conditions, without a rooting powder treatment in a steamed peat-perlite substrate. Auxin-untreated microcuttings of S. gemella, S. × kitaibeliana and S. omissa, but not S. × abscondita, rooted better than ones treated with indole-3-butyric acid. This is the first time a micropropagation protocol for S. omissa, S. × abscondita and S. × kitaibeliana has been published.
