The effect of cultivation practises on both the phytochemical profile and biological activity aqueous ethanol extracts Chelidonium majus L. was studied. Extracts were prepared from aerial parts same plant population collected in wild grown under organic farming conditions. Both qualitative quantitative analyses alkaloids flavonoid derivatives performed by LC/MS methods, cytotoxicity lyophilised studied B16-F10, HepG2, CaCo-2 cells. Coptisine dominant alkaloid wild-grown plants, whereas after...

Multilocation testing remains the main tool for understanding varietal responses to environment. Here, Latvian and Norwegian hull-less hulled barley varieties were tested in field experiments Latvia Norway order assess adaptability across environments (sites). Two (cv Irbe cv Kornelija) one variety Pihl) along with Rubiola) Tyra) under conventional organic management systems. The grain yield, together physical chemical parameters compared, yield protein stability determined. Overall, of was...

The extensive application of synthetic insecticides and herbicides over the past 50 years has led to a number problems, including negative effects on non-target organisms evolution pesticide-resistant pests. As an alternative means pest control, plant-based biopesticides have emerged. While developing new bioinsecticide, allelopathy both target pests crops must be evaluated. We evaluated volatile organic compounds (VOCs), total phenolic content (TPC), sugars antiradical activity (ARA), as...

The objectives of the investigation were to identify competitive traits in cereal species order contribute development a methodology for evaluation genotypes their capacity against weeds, which is important organic breeding aims. was carried out with spring barley, oat, winter triticale and wheat crop rotations two different locations. Relations between weed dry weight evaluated by Pearson correlation coefficients. results stressed significance some competitiveness weeds purposes: (i) growth...

Glechoma hederacea L. is a medicinal plant that known in traditional medicine for its anti-inflammatory, antibacterial, antiviral, and anticancer properties. This study evaluated the potential commercial production of G. compared chemical composition activity 70% ethanol extracts steam-distilled essential oils from wild-grown cultivated collected different harvesting periods. The main compounds identified were phenolic acids (chlorogenic rosmarinic acids) flavonoid O-glycosides. oil varied...

Rye (Secale cereale L.) has been cultivated in Europe since ancient times and is second only to wheat among the grains most commonly used production of bread.Rye traditionally consumed as wholemeal products Baltic countries.In Latvia, rye bread rich with traditions, one more favourite types bread.Our objectives were determine grain quality suitability popular winter cultivars Latvia for wholegrain flour baking.Three population 'Kaupo', 'Amilo', 'Dankowskie Amber' three hybrid 'Brasetto F1',...

Organic farmers need varieties adapted to variable growing conditions, because in organic farms environmental conditions significantly vary soil nutrient status, weed and disease pressure not only between years, but also among within a season.Modern developed under high input agricultural systems do always perform well conditions.Therefore, such of cereals that can adapt maintain productivity.One the ways promote adaptation environment is variety mixtures.Field trials were conducted during...

× One of key questions in breeding for organic agriculture is about most appropriate selection environment. A successful man-made cereal species, triticale (Triticosecale Wittm. ex A. Camus.) - very suitable growing crop management systems but little research has been conducted on agriculture. Field trials were carried out Priekuïi during 2009-2012. hundred F4 winter lines sown conventionally and organically managed fields. Selection the approximately ten best each environment, according to...

Diseases of rye (Secale cereale), an important crop in Latvia, might be a risk factor for production. The aim the study was to determine features leaf diseases, estimate diseases under conditions and compare various schemes fungicide treatment that possibly useful integrated disease control. Field trials were carried out from 2009 2012 two locations Latvia - State Stende Cereals Breeding Institute Priekuïi Plant Institute. Sixteen (two cultivars each year, sites, four years) established...

Galium odoratum, commonly known as sweet woodruff, is a perennial herbaceous plant that contains coumarin and recognized for its medicinal properties. In this study, the influence of sunlight exposure on phytochemical composition anti-inflammatory potential G. odoratum extracts assessed. The from cultivated wild-grown plants were analyzed via chromatographic mass spectrometric methods. addition, total phenolic content, antioxidant activity, effects macrophage polarization results revealed...

Abstract Triticale (× Triticosecale Wittm.) is mainly used for animal feed, but recent studies have shown its possible beneficial effect human health. The objective of this study was to investigate the nutritional quality triticale grown under different cropping systems in Latvia. Two winter varieties, ‘Inarta’ and ‘Ruja’, were cultivated 2014 2015 conventional organic systems. Protein, starch, total dietary fibre determined using standard methods. Ultrasound assisted extraction isolation...

Abstract The common dandelion ( Taraxacum campylodes G.E.Haglund) is known for its medicinal properties and as a non-toxic, highly nutritious edible plant. Even though the herb mostly collected in wild, food pharmaceutical industries prefer cultivated plant material. Cultivation offers possibility to achieve predictable yields, ensure botanical identity of plants products can be certified according organic or biodynamic standards; therefore interest domestication growing. Due scarcity...

Employing cereal genetic variation in breeding programmes for organic farming is one of the ways to create varieties with higher stability and adaptability. The aim study was compare evaluate grain yield, quality other traits barley pure lines, hybrid populations, variety mixtures, as well winter wheat populations parental varieties, conventional systems. Significant evidence advantages using mixtures under management systems not observed. More respect adaptability unfavourable environments...

Germination improves nutritional quality of cereals due to synthesis various phytochemicals.The aim the current research was evaluate influence applied germination conditions on changes in total phenolic compounds (TPC) and antioxidant activity triticale, hull-less barley, oat, wheat, rye grains.Triticale (cv.Inarta), barley (cv.Irbe), oat (cv.Lizete), (cv.Kaupo), wheat (cv.Ellvis) grains were cleaned, washed steeped water at ratio 1:2 (grains water) for 24 h 222 C.After steeping, grain...

The necessity to increase genetic diversity in agriculture has been widely discussed during the last decades.Heterogeneous populations is one of ways varieties self-pollinating cereals.The aim this research was compare grain yield, its stability, foliar diseases severity and competitiveness against weeds spring barley (Hordeum vulgare) homogenous varieties.Field trials consisting three types (simple, complex composite cross -CCP) containing different levels check were carried out 2015-2018...
