As 2021 saw the launch of United Nations Decade on Ecosystem Restoration, it highlighted need to prepare for success over decade and understand what public economic financial incentives exist support sustainable forest landscape restoration. To date, Initiative 20 × 20, a coalition 18 Latin American countries, has committed place 50 million hectares under restoration conservation by 2030. Understanding policies in these countries that turn those commitments into action, however, is very...

Legumes are the major element of grassland ecosystem, on which forage quality depends. Breeding pasture varieties in perennial legumes firstly aims at achieving tolerance and persistence legume component pasture. In species having low natural grazing (lucerne red clover) it is necessary to conduct breeding for biological, morphological physiological characteristics, directly related tolerance. high (white clover, birds foot trefoil, sainfoin), considered as a function particular adaptive...

The objective of the trial was to study physiological function and potential ecological significance non-glandular trichomes in red clover based on their relation leaf transpiration intensity. rate, relative water content deficit leaves were recorded field-grown, high slightly pubescent genotypes. According results, presence nonglandular epidermal surface a micromorphological trait related regulation stressful conditions. Non-glandular significantly enhanced retention tissue at deficit. In...

The aim of present study was to get comparative data on forage productivity and quality Checz cultivars legumes in the conditions Northern Bulgaria respectively select species genotypes with potential for successful introduction structure production Bulgaria. Five crops were observed respective cultivars: Egyptian clover (Trifolium alexandrinum L.), cv. Faraon; crimson incarnatum Kardinal; annual bird's-foot-trefoil (Lotus ornithopoides L.) Junak; black medick (Medicago lupulina Ekola white...

From the first to third growing season in field test carried out at Experimental Station of Soybean (Pavlikeni, Bulgaria) was observed 12 accessions red clover, including two Bulgarian diploid varieties Nika 11 (standard) and Sofia 52, four local populations next six foreign tetraploid varieties, i.e. Kvarta, Astur, Carbo, Elanus, Fregata Larus. The goal study determine effect ploidity level as well adaptive variability on fresh mass yield, dry yields their persistence an agro-ecological...

Creation of plant associations with maximum stability yields in the regional ecological conditions for which they have been designed is key modern agriculture. The present study aimed to investigate impact environment on productivity and six grass (red fescue, pure stand; red fescue birdsfoot trefoil; tall Kentucky bluegrass; bluegrass alfalfa; trefoil) four locations (mountain slope eastern, western, northern south-eastern facing direction). Methods dispersion, regression nonparametric...

The evaluation of climate plasticity and content free amino acids, sugars fatty acids in Bulgarian soybean cultivars were used as an innovative approach. field performance, expression metabolomic profiles leaves, green seeds mature plants grown from low temperature pre-treated not-treated assessed by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) gas chromatography/mass spectrometry (GC/MS). data the morphological indicators, metabolites confirmed that had...

The aim of this study was to evaluate the tolerance twelve genetic accessions red clover Powdery mildew (Erysiphe polygoni DC). trial carried out during 2014-2015 at Experimental station soya-bean Pavlikeni a natural infection. plant type reaction evaluated by fourgrade scale depending on % leaves with typical symptoms. A significant effect (P<0.001) genotype, and hence level ploidy, disease powdery established. Average for period study, tetraploid were rated as moderately susceptible...

Technological qualities of the seeds, including their mass, play an important role in purposeful use soybean for food production. The purpose this study is to determine potential specific crosses and recombinant lines combinative breeding high yielding large-seeded varieties. During period 2018-2019 F3 F4 hybride generations with participation ultra-early mature cultivar Romantica were studied. Data used evaluate: presence extent positive transgressive forms by absolute seed mass family...

We have witnessed a drastic increase in global fires recent years that are strongly linked to climate change. On the other hand, prescribed applied agricultural practice; however, their effectiveness is controversial. It important study effects of both types – wild and predict impact on biota. In this study, four different locations Central Norther Bulgaria recovered after fire were studied concerning biodiversity abundance first colonizer species. Two generations from demonstrated legume...

A study of the species composition, biological, morphological and productive characteristics legume component forest Chrysopogon gryllus meadows a year with high spring moisture availability was conducted. very diversity leguminous grasses found - 17 from 7 genera. Until mowing meadows, distinct turnover an almost equal total productivity dry mass per ten-day period observed. Thus, fresh and, accordingly, nitrogen fixation levels in orchard have stable level until mowing. The annual clovers...

The objective of this experiment was to: 1) examine the degree influence hereditary factors and conditions growth (region cultivation, season type cultivation) on phenotypic variance leafiness in breeding populations red clover; 2) quantify heritability experimental variances order to assess opportunities for clover improved leafiness. Five genotypes (four synthetic variety Sofia 52) were screened study. Among studied as environmental variables, had strongest effect clover. In second...

Eight red clover subspecies are registered in Europe but it can be considered that the high genetic diversity and local adaptation existing at a level is unused. The experiment aimed studying agronomical traits of hybrids obtained from crosses wild Trifolium pratense - snow (Trifolium ssp. nivale (W.D.J. Koch) Arcang.) cultivated sativum). Under field conditions, two half-sib families F1 generation crossbreeding were selected compared to paternal variety Nika 11 for three years. According...
