Glechoma hederacea L. is a medicinal plant that is known in traditional medicine for its anti-inflammatory, antibacterial, antiviral, and anticancer properties. This study evaluated the potential for commercial production of G. hederacea and compared the chemical composition and activity of 70% ethanol extracts and steam-distilled essential oils fr...

The effect of cultivation practises on both the phytochemical profile and biological activity of aqueous ethanol extracts of Chelidonium majus L. was studied. Extracts were prepared from aerial parts of the same plant population collected in the wild and grown under organic farming conditions. Both qualitative and quantitative analyses of alkaloids...
Article
Chamomilla recutita is a cross-pollinating medicinal plant widely used in traditional medicine both in Latvia and globally. In this study, we evaluated the genetic and morphological diversity as well as the chemical profiles of plants collected from semi-wild populations in Latvia as well as various varieties found in Central Europe. All samples we...
Conference Paper
Full-text available
The necessity to increase genetic diversity in agriculture has been widely discussed during the last decades. Heterogeneous populations is one of the ways to increase genetic diversity in varieties of self-pollinating cereals. The aim of this research was to compare grain yield, its stability, foliar diseases severity and competitiveness against th...

Faba beans are highly nutritious because of their high protein content: they are a good source of mineral nutrients, vitamins, and numerous bioactive compounds. Equally important is the contribution of faba bean in maintaining the sustainability of agricultural systems, as it is highly efficient in the symbiotic fixation of atmospheric nitrogen. Th...

Multilocation testing remains the main tool for understanding varietal responses to the environment. Here, Latvian and Norwegian hull-less and hulled barley varieties were tested in field experiments in Latvia and Norway in order to assess the varieties adaptability across environments (sites). Two Latvian (cv Irbe and cv Kornelija) and one Norwegi...

European pulse production faces a continued loss of cultivated area along with decreasing or stagnant yields. Vicia faba is a traditional legume with high genetic diversity cultivated in a wide range of European climates. Therefore V. faba is promising to identify stable and high yielding genotypes for specific target environments. Mid-latitudes ar...

Wheat is one of the major grains in the diet of the world’s population and thereforeit may have a great impact on human health. The yield and chemical compositionof grains can vary greatly due to genetic and environmental factors. The aim of thepresent study was to assess how different climatic conditions affect the chemicalcomposition of wheat gra...

Triticale (× Triticosecale Wittm.) is mainly used for animal feed, but recent studies have shown its possible beneficial effect for human health. The objective of this study was to investigate the nutritional quality of triticale grown under different cropping systems in Latvia. Two winter triticale varieties, ‘Inarta’ and ‘Ruja’, were cultivated i...

The aim of the study was to investigate changes of physical, microbiological, and sensory properties of muesli with germinated flakes during storage. Germinated flakes were made from conventionally grown grains: hull-less barley, hull-less oat, rye, wheat, and triticale in various proportions. Breakfast cereals samples were packaged in Doypack (sta...

Grain products are the main source of carbohydrates but they also contain other bioactive substances such as phenolic compounds. Content of phenolic compounds differ among cereal types, varieties, and farming methods. The aim of the current study was to assess total phenolic content and radical scavenging activity in different oats and barley varie...

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.) - is very suitable for growing in organic crop management systems but little research has been conducted on breeding triticale for organic agriculture. Field tr...

The objectives of the investigation were to identify competitive traits in cereal species in order to contribute to development of a methodology for evaluation of cereal genotypes for their competitive capacity against weeds, which is important for organic breeding aims. The investigation was carried out with spring barley, spring oat, winter triti...

The State Priekuli Plant Breeding Institute (previously Wenden, Cēsis or Priekuli Experimental and Breeding Station) started its operation in 1913. The main aims of research have remained the same for the last century: to provide knowledge on crop management and to create crop varieties suitable to local growing conditions and farming systems, acce...

Diseases of rye (Secale cereale), an important crop in Latvia, might be a risk factor for rye production. The aim of the study was to determine features of rye leaf diseases, to estimate the risk of rye diseases under conditions of Latvia, and to compare various schemes of fungicide treatment that possibly might be useful for integrated disease con...

Prior to the registration of a new variety, it is required to undergo Distinctness, Uniformity and Stability (DUS) testing. Preparing a newly developed variety to meet the requirements of DUS testing is a lengthy process, particularly regarding aspects of uniformity and stability. Field testing of a large number of lines is time and resource intens...

Project
The project aim is to develop innovative technologies for growing of wild spring medicinal and aromatic plants (MAPs) under organic agriculture for potential commercial use in medicine, cosmetics and food. The nine wild medicinal plant species distributed in Latvian natural habitats - COWSLIP (Primula veris), WOODRUFF (Galium odoratum), MEZEREON (Daphne mezereum), COLTSFOOT (Tussilago farfara), PASQUEFLOWER (Pulsatilla pratensis), LILY OF THE VALLEY (Convallaria majalis), GROUND-IVY (Glechoma hederacea), GREATER CELANDINE (Chaledonium majus) and LADY’S MANTLE (Alchemilla spp) with high market potential have been pre-selected and included in the project.
Project
Create and support cooperation between agriculture, agricultural product processing industry and science, in order to: - develop innovative methods for cultivation of globally demanded medicinal plants (ginseng (Panax sp.) and Chinese horseradish (Angelica sinensis)) that are suitable for Latvia’s agro-climatic conditions; - create new products based on ginseng (Panax sp.) and Chinese horseradish (Angelica sinensis); - disseminate knowledge gathered during the project via European Innovation Partnership network and other communication channels.
Project
The research project intends to develop an technology for organic cultivation of high value MAPs, such as valerian (Valeriana officinalis L.), chamomile (Matricaria recutita), echinacea (Echinacea angustifolia), common dandelion (Taraxacum officinale), and siler (Saposhnikovia divaricata) for further use in the fields of medicine, condiments, food and cosmetics. The main aims are: To evaluate morphological, biochemical, genetic diversity of the local natural populations of MAPs that are interesting for the market and compare them with the genotypes of foreign origin; To determine the quality of the raw material, stability of the yield and composition of active substances in the researched MAPs; To develop an innovative methodology for selection and organic cultivation of high value MAPs
