Researchers from SIA “Field and Forest” and the Institute for Environmental Solutions continues to develop innovative solutions for growing and cultivation of ginseng and Chinese horseradish in Latvia. They just closed 2nd year of field research and are heading to develop new value-added tea products in cooperation with tea producer SIA “Bargi”.


Second season of field research on different growing conditions for ginseng and Chinese horseradish has concluded. As both plants are perennial, in 2019 the researchers continued to make observations of plants that were planted in the season of 2018. During the second season, researchers observed, measured and analysed effects of light intensity, meteorological conditions and soil conditions on the growth of ginseng Effects of different light intensity were measured by testing different types of shading, both natural (forest ecosystem) and artificial (artificial shading with specially made tent) within experimental sites. In order to find the most suitable conditions and cultivation technology for both plants, researchers tested different growing solutions. For example, ginseng was tested to be grown in experimental field and in forest ecosystem. During the current winter season, researchers do testing and analysis of meteorological conditions. In the upcoming Spring they will be able to analyse the effect by the winter weather conditions on each of the species. After the research on the best growing conditions, researchers in cooperation with tea producing experts will start to develop brand new value-added products.

Considering that ginseng and Chinese horseradish are perennial plants, only in year 2021, the researchers will be able to do quality assessment of the roots of the plants. In spite of that , researchers has already started to work together with leading tea production company in Latvia SIA “Bargi” to develop new products containing abovementioned herbs. To find new value-added product, SIA “Bargi” is testing different mixtures that includes ginseng and Chinese horse radish.

Innovative methods for cultivation of ginseng and Chinese horseradish will be developed as a part of the project “Developmend of innovative technologies for cultivation and food production of ginseng (Panax spp.) and Chinese horseradish (Angelica sinensis)” No.  17-00-A01620-000008, which is supported by EU European Agricultural Fund for Rural Development, Rural Development Programme.

Team of researchers from the SIA “Field and forest” and Institute for Environmental Solutions (IES) started year 2020 with research on germination under different conditions for 9 wild spring medicinal and aromatic plants (MAPs) species, then developed new accelerated seed sprouting technology for each of them.

Seed germination research is an important step in development of innovative technologies for cultivation of 9 wild spring MAPs for organic farming needs, as well as with potential commercial use in pharmacy, cosmetic and food industries. To develop innovative cultivation technologies IES and SIA “Field and Forest” will cooperate with Latvian Institute of Organic Synthesis.

Many wild MAP species that grow in Latvia hold a high market potential and different biological properties. These are species such as 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). Team of researcher has started evaluation of cultivation risks for each of 9 MAPs in order to find solutions for these risks.

In this research season researchers focus on germination of plant seeds to find the best sprouting solutions for each of selected MAPs. For development of improved accelerated seed sprouting technology researchers tested different environments – climate chambers and greenhouses. The results will indicate the most suitable environment for each of researched MAP. Seed quality is very important factor for yield production amount and quality. It contributes to high germination rate, promotes productive plant formation and helps to outgrow weed, as well as increases effectivity of nutrient use.

Since autumn 2019 scientists from Latvian Institute of Organic Synthesis have been carrying chemical analysis of plant parts and seeds gathered in sampling expeditions during summer. The results of analyses will allow researchers to assess genetic resources of wild species that grow in Latvia and to evaluate the risks and solutions for their cultivation for commercial use.

The research is a part of the project “Innovative solutions for growing technologies and applications of spring medicinal and aromatic plants” (Nr. 1.1.1.1/18/A/043). It is supported by European Regional Development Fund, as a part of Measure 1.1.1.1 “Industry-Driven Research” of specific objective 1.1.1 “To increase the research and innovation capacity of scientific institutions of Latvia and their ability to attract external funding by investing in human resources and infrastructure”.

A team of leading researchers Dr Ilva Nakurte, Dr Arta Kronberga and Dr Andrea Primavera from SIA “Field and Forest” and Institute of Environmental Solutions (IES) were invited to present their conclusions on genetic diversity of medicinal and aromatic plants (MAPs) during the “6th World Congress on Medicinal and Aromatic Plants” in Cyprus, November 2019.

The wild MAPs such as valerian (Valeriana officinalis L.), chamomile (Matricaria recutita), echinacea (Echinacea angustifolia), common dandelion (Taraxacum officinale), and siler (Saposhnikovia divaricata) are known to have high concentration of active substances, and therefore they are already used in medicine, condiment, food and cosmetic industries. Since 2017, international team of researchers has been carrying innovative and holistic research on genetic diversity of above mentioned MAPs to find the most suitable herbs for growing and cultivation in Latvia’s climate conditions. In experimental garden located in Priekuļi municipality in Latvia, researchers measured and analysed MAPs’ genetic diversity, stability of yield morphological, biochemical and other parameters of these 5 abovementioned plants, grown in experimental garden located in Priekuļi municipality in Latvia.

To share their experience and scientific conclusions researchers presented two posters during the 6th World Congress on Medicinal and Aromatic Plants: “Biologically active substances of wild valerian (Valeriana officinalis L.) roots from different regions of Latvia” and “Growing Technology for Dandelion (Taraxacum officinale L.) Under Organic Croping System”. Presentation materials here.

Research “Genetic Diversity of Medicinal and Aromatic Plants” is in the last phase. Researchers currently carry out chemical analysis of 5 medicinal and aromatic plant samples to gather results. The last step in this research will be data analysis and selection of genotypes suitable for growing and cultivation in Latvia’s climate conditions, as well as development of innovative methodology for organic cultivation of high value MAPs.

The research is a part of the project “Growing genetic diversity of medicinal and aromatic plants” (Nr.1.1.1.1/16/A/307). It is supported by European Regional Development Fund, as a part of Measure 1.1.1.1 “Industry-Driven Research” of specific objective 1.1.1 “To increase the research and innovation capacity of scientific institutions of Latvia and their ability to attract external funding by investing in human resources and infrastructure”.

To develop innovative technologies for growing wild spring MAPs, during summer of 2019 researchers conducted a study of historical and existing knowledge of chosen plants by implementing ethnobotany expeditions. Researchers visited rural areas to conduct interviews with locals. While in Rūjiena county (Vilpulkas, Ipiķu, Jeru and Lode parish) researchers conducted 24 interviews, in Naukšēni county (Naukšēni and Ķoņi parish) they collected information from 14 interviews. Overall, during ethnobotany expeditions the researchers interviewed 38 respondents who were more than 40 years-old – 29 women and 9 men. The results revealed fresh and unexpected information about the traditional use of spring MAPs. For example, most of the respondents did were not familiar with woodruff and ground-ivy, but lady’s mantle turned out to be the most commonly used in these regions.

To evaluate genetic resources of Latvia’s local herbs, the researchers also carried out sampling expeditions to collect local genetic resources (plant seeds and herbal drugs).  Gathered seeds that can sprout in short period of time were planted into the experimental gardens in Priekuļu municipality. Seeds that takes longer to sprout will be tested in laboratory where new methodologies for accelerated sprouting will be developed. Afterwards, chemical analysis to estimate genetic resources of local plants will be conducted.

After the new methods for improving seed germination have been developed for each of 9 wild spring MAPs, the research will be ready to go into the next phase – evaluation of main risks for commercial growing of MAPs, as well as searching for alternatives to prevent the identified.

The research is a part of the project “Innovative solutions for growing technologies and applications of spring medicinal and aromatic plants” (Nr. 1.1.1.1/18/A/043). It is supported by European Regional Development Fund, as a part of Measure 1.1.1.1 “Industry-Driven Research” of specific objective 1.1.1 “To increase the research and innovation capacity of scientific institutions of Latvia and their ability to attract external funding by investing in human resources and infrastructure”.

Students from Latvia University of Agriculture and University of Latvia are participating in this research process by doing additional assessments of the dandelions in experimental gardens. Līva Marta Roze who is studying in faculty of biology (University of Latvia) has developed a research paper “Development of descriptors for characterising morphological variability of morphological features of Taraxacum officinale Weber and characterisation of the diversity of local populations”. Faculty of agriculture student Jānis Gailītis continues to develop his bachelor’s thesis on the commercialized growing of dandelions in agro-climatic conditions of Latvia.

The research on 5 medicinal and aromatic plants started on March 2017. While the third season of experimental gardens in Priekuļi parish is still in progress, team of researchers are preparing of the last stage of the research – analysis of the most important MAPs parameters to announce the most appropriate genotypes and organic production of MAPs that are also the most suitable for biological agriculture farmers, organic farmers, pharma, food and cosmetics companies and households use in Latvia conditions.

The research is a part of the project “Growing genetic diversity of medicinal and aromatic plants” (Nr.1.1.1.1/16/A/307). It is supported by European Regional Development Fund, as a part of Measure 1.1.1.1 “Industry-Driven Research” of specific objective 1.1.1 “To increase the research and innovation capacity of scientific institutions of Latvia and their ability to attract external funding by investing in human resources and infrastructure”.

In Spring 2019, the Institute for Environmental Solutions and SIA “Field and Forest” is launching the final season for experimental gardens to gather data, analyse genetic resources and the best growing conditions for 5 medicinal and aromatic plants. The aim is to find the best growing technologies for each of plants of interest.

The selected medicinal and aromatic plants – valerian (Valeriana officinalis L.), chamomile (Matricaria recutita), echinacea (Echinacea angustifolia), common dandelion (Taraxacum officinale), and siler (Saposhnikovia divaricata) are proven to have high concentration of active substances. Therefore, they are important ingredients of pharmacy and cosmetic products. Considering that Latvia’s weather conditions and soil parameters could be favourable for cultivation of abovementioned plants, in 2017 IES in cooperation with SIA “Field and Forest” developed experimental gardens for detailed analysis of selected plants’ genotypes, yield, phytochemical quality and other criteria of growing these plants. As a result, researchers will declare the most suitable genotypes and organic production for organic farming, pharmacology, food production and cosmetics companies, as well as for household use.

In Spring 2019, IES and “Field and Forest” starts the final season for experimental gardens. The gardens will provide data of the plant growth, progress and quality of harvest, thus, helping to develop the specifically proven growing technology for each species of interest. Currently, after the winter season, plants are in vegetation period. Overall conditions of winter season 2018/2019 have been good for all species and varieties. In the end of March, vegetation period of valerian and dandelion have restarted. The first spring counting of plants researchers plan to do at the end of April, when the vegetation will be fully recovered. In April, the weather conditions are changing a lot, thus, affecting the plant growth. Despite of that, field works have already started.  Considering that weeds can outpace medicinal plants by growing faster in lower temperatures, the weeding process has started.

Fieldworks in experimental gardens will continue till October 2019. During this period, researchers will continue to monitor all the gathered plant species and their characteristics that are important in organic farming and agriculture. During the whole season the researchers will do the chemical analysis of the harvested plants. This will be the third and last year of the project and the second season of the medicinal and aromatic plant experimental gardens.

Chemical analysis and the research are a part of the project “Growing genetic diversity of medicinal and aromatic plants” (Nr.1.1.1.1/16/A/307). It is supported by European Regional Development Fund, as a part of Measure 1.1.1.1 “Industry-Driven Research” of specific objective 1.1.1 “To increase the research and innovation capacity of scientific institutions of Latvia and their ability to attract external funding by investing in human resources and infrastructure”.

The researchers from the Institute for Environmental Solutions and SIA “Field and Forest” analyses chemical composition of valerian (Valeriana officinalis L.) and common dandelion (Taraxacum officinale) samples which were gathered in Latvia in 2017. The results were compared with parameters of medicinal and aromatic plants that are included in the European Pharmacopoeia standard.

The leading researcher Arta Kronberga from SIA “Field and Forest” highlights that the results of analysis proves the assumption that we can find different characteristics between same medicinal and aromatic plants growing in Latvia’s territory. To give an example, a valerian from the Raunas municipality contains of 46% of the minimum amount required Ethereum, while samples from Lēdmane parish, Renda parish, and Jaunsvirlauka parish, extend the minimum requirements of more than 250%.

Analysis of common dandelion samples show similar results. Researchers analysed amount of three phenolic acids (antioxidants) in the roots of gathered dandelions and found that it differs more than two times from sample to sample. The biggest amount of phenolic acids was found in the dandelions that were gathered in the Priekuļi municipality, Amata municipality and Kuldīga municipality, but the least percent of phenolic acids was found in the samples from the Talsi municipality and Vecumnieki municipality.

The samples were collected in various areas in Latvia with different soil characteristics, hydrological regime, compositions of plants, and management methods, therefore, researchers cannot make very precise assumptions of genetic potential of gathered plants, not yet. To find more precise conclusions, further research is needed. Thus, the researchers are currently making the experimental sample sites, where they will be able to compare the samples of plants within the same growing conditions.

Chemical analysis and the research is a part of the project “Growing genetic diversity of medicinal and aromatic plants” (Nr.1.1.1.1/16/A/307). It is supported by European Regional Development Fund, as a part of Measure 1.1.1.1 “Industry-Driven Research” of specific objective 1.1.1 “To increase the research and innovation capacity of scientific institutions of Latvia and their ability to attract external funding by investing in human resources and infrastructure”.
