Abstract:

Purple coneflower, Echinacea sp. (Asteraceae), is a herbaceous perennial native to North America. Within the past decade, extensive research has been conducted to confirm echinacea's immunostimulatory, antiviral, and antibacterial benefits to humans. E. angustifolia, E. purpurea, and E. pallida are the primary species grown and studied for the herbal industry. However, there are other species and cultivars that may produce higher yields in biomass and chemical quality. The objective for this study is to evaluate the differences in biomass and phenolic content of five cultivars of E. purpurea and five species of Echinacea under Kentucky growing conditions. Differences in biomass (dry weight) of Echinacea species and cultivars harvested after the first year of growth was determined. There was a significant difference in total dry weight between E. purpurea cultivars. E. purpurea `Bright Star' and `Clio' produced significantly greater total dry weight compared to all other cultivars. There was no significant difference in root or flower biomass between cultivars. Biomass production differed between Echinacea species for root, vegetative, and flower parts. The total biomass of E. purpurea and E. tennesseensis was significantly higher compared to other species. E. pallida and E. paradoxa were not significantly different from E. purpurea in root biomass, even though both species produced less above-ground growth. E. tennesseensis produced 45% to 105% more flowers compared to other species. Differences in phenolic content between species and cultivars will also be presented.

Abstract:

The aim of the study was to study the biological activity of extracts of the aerial part and rhizomes with the roots of Echinacea purpurea (L.) Moench. Used laboratory and statistical methods. The activity of the extracts was studied by biotesting on the seeds of cress (Lepidium sativum), barley (Hordeum vulgare) and millet (Panicum miliaceum). It has been established that echinacea extracts affect a wide range of concentratins, plant phytomass increases and the sowing qualiies of seeds are stimulated. It is concluded that the further study of echinacea extracts is promising.

Abstract:

Purple Coneflower [Echinacea sp. (Asteracea)] is of great value to the horticultural, pharmaceutical, and herbal industry. More research is needed to determine cultural practices that will produce a plant high in biomass and phenolic content, the chemical used for testing the quality of the harvested plant on a percent basis of roots, flowers and vegetative parts. The objective of this experiment is to determine if biomass and phenolic content of Echinacea purpurea and E. purpurea `Magnus' is influenced by fertilization after flower bud removal and vegetative pruning. The second objective of this study is to form an evaluation of the differences in biomass and phenolic content of five cultivars of E. purpurea and five species of Echinacea. Biomass and phenolic content will be evaluated to determine if exposing these plants to various treatments increases the quality of the plant over 1 and 2 years of growth. Differences in dry weights of Echinacea species and cultivars harvested after the first year of growth was determined. There was a significant difference in total dry weight between E. purpurea cultivars. Echinacea purpurea `Bright Star' and `Clio' significantly produced the most total dry weight compared to all other cultivars. There was no significant difference in root or flower biomass between cultivars. Biomass of Echinacea species was significantly different in root, vegetaive and flower parts. The total biomass of E. purpurea and E. tennesseensis was significantly higher compared to other species. Echinacea pallida and E. paradoxa were not significantly different from E. purpurea in root biomass, even though both species were small in above ground growth. Echinacea tennesseensis significantly produced 45% to 105% more flowers compared to other species. Differences in phenolic content between species and cultivars will also be presented.

Abstract:

Fresh Echinacea purpurea plant is a rich source of caffeic acid derivatives, which actively participate in the regulation of immune function. Herein, we describe a novel process for the production of fresh Echinacea purpurea juice rich in caffeic acid derivatives. This novel process includes steam heating (100°C, 15 min) before squeezing the juice to increase the recovery of caffeic acid derivatives from the flower or leaf by 1.5 to 3.7 fold. The recovery was further enhanced by 11–20% using ultrasonication at 500 W for 30 min. The flower, leaf, and root juice of Echinacea purpurea could be preserved for 4 weeks (4°C) or 6 months (−18°C) following ultra-high-pressure pasteurization (300 MPa, 15 min). Under these conditions, more than 90% of active cichoric acid was retained. Furthermore, the frozen-stored Echinacea purpurea juice exhibited similar or better immunoenhancement properties when measured by organ index, ear swelling, and carbon clearance test in mice compared with that of the positive control group (P < 0.05). Our results suggest that a combination of steam, ultrasound, and ultra-high-pressure treatment could serve as a superior process for the preparation of functional Echinacea purpurea juice.

Abstract:

We aimed to investigate the effects of Calendula officinalis and Echinacea purpurea extracts in terms of growth parameters, antibacterial activity and phenolic profile in tomato infected by Clavibacter michiganensis subsp. michiganensis (CmmT7). A significant difference was observed in E. purpura extract, indicating the highest effects on plant height (27.25 cm), fresh plant weight (28.45 cm), root length (24.42 cm), and root weight (6.74 g) (p<0.05). Moreover, Calendula officinalis and Echinacea purpurea extracts showed significant inhibitory activity against CmmT7 (p<0.05). Among phenolic compounds, the only chlorogenic acid amounts were varied in the tomato seedlings leaves with C. officinalis extract (K3) + CmmT7, E. purpurea extract (E3) + CmmT7 and CmmT7 (p<0.01). Moreover, chlorogenic acid amount was approximately 9 times higher than in CmmT7-treated leaves when compared to control. The results showed that application of the extracts of these plants had a significant influence on bacterial canker and growth parameters.

Abstract:

The results of many years of field research on the effect of stocking density of different types of Echinacea spp. on its productivity are discussed. It was found that when the Echinacea purpurea crops were thickened, the collected raw material had a high percentage (more than 50%) of stems, which negatively affected its quality. An increase in the density of Echinacea pallida crops has less effect on the formation of generative shoots. Long-term research has revealed patterns that determine the productivity of Echinacea spp. at different planting densities. This made it possible to calculate and recommend for production the density of plants at which the optimal yield of the agrocenosis will be achieved: for Echinacea purpurea – 100-110 thousand/ha, and for Echinacea pallida – 120-140 thousand/ha.

Abstract:

Biological Effects of Echinacea Purpurea on Human Blood CellsThe aim of this study was to investigate radioprotective properties of Echinacea purpurea tablets in vivo. We analysed lymphocyte chromosome aberrations (CA), micronuclei (MN), apoptosis of leukocytes and haematological parameters in a group of radiation workers who were identified as carrying dicentric chromosomes in their lymphocytes. All radiation workers were taking two 275 mg Echinacea tablets b.i.d., according to a pharmacist's recommendation. All parameters were analysed before and after the two-week treatment. At the end of the treatment lymphocyte CA frequency dropped significantly, and the number of apoptotic cells increased. The inverse lymphocyte-to-granulocyte ratio at the beginning of the study changed to normal at its end. In conclusion, biological effects observed after administration of Echinacea purpurea preparation suggest that it may be beneficial for the prevention of adverse health effects in workers exposed to ionising radiation.

Abstract:

ZusammenfassungDie drei Sonnenhutarten Echinacea angustifolia, E. pallida und E. purpurea werden als Ausgangsmaterial für die Produktion phytotherapeutischer und homöopathischer Zubereitungen genutzt, welche als unspezifische Immunstimulanzien Einsatz finden. Dabei sind vermutlich sowohl nieder- als auch hochmolekulare Inhaltsstoffe an der Wirkung beteiligt. Aus den verschiedenen Pflanzen und Pflanzenteilen entstehen durch Anwendung unterschiedlicher Herstellungsmethoden aufgrund der Vorgaben der Arzneibücher Zubereitungen, die erhebliche Unterschiede in ihrer stofflichen Zusammensetzung erwarten lassen. In den vorliegenden Untersuchungen wurden daher verschiedene Echinacea-haltige Zubereitungen hinsichtlich des Vorkommens von Kaffeesäurederivaten, Alkamiden, Polysacchariden und Proteoglykanen analytisch charakterisiert und verglichen.Erwartungsgemäß zeigte sich, dass sich homöopathische Urtinkturen bzw. alkoholische Extrakte sowohl hinsichtlich der hochmolekularen Inhaltsstoffe (Polysaccharide, Proteoglykane) als auch bei den polaren und lipophilen niedermolekularen Inhaltsstoffen von Echinacea-purpurea-Presssaftzubereitungen deutlich unterscheiden und sie daher nicht als äquivalent angesehen werden können. Auch zwischen den homöopathischen Urtinkturen der einzelnen Arten existieren Unterschiede und selbst innerhalb der Echinacea-purpurea-Presssaftzubereitungen konnten, je nach Herstellungsart, verschiedene Inhaltsstoffmuster detektiert werden. Bei der Bewertung von Wirksamkeit und Unbedenklichkeit von Echinacea-Zubereitungen sollten diese Unterschiede in Zukunft mehr berücksichtigt werden.

Abstract:

Progenies derived from self-pollination and parent–offspring backcrosses of Echinacea purpurea (L.) Moench accession PI 631307 revealed that a sporophytic self-incompatibility (SI) system was operating in this germplasm. Offspring of progenies from the original accession were self-incompatible, but most self-pollinations resulted in some self-seed set. One seedling from such a self-pollination was reciprocally crosscompatible with its parent, proving that a sporophytic SI system was operational. The F3BC1 progeny could be classified into two offspring groups. The first group of two seedlings was reciprocally compatible with its seed parent but reciprocally incompatible with its pollen parent based on stigma collapse of the seed parent florets 2 to 4 days after pollination. The second offspring group of three seedlings was reciprocally incompatible with its seed parent but reciprocally compatible with its pollen parent. Seed set data were in agreement with classification by stigma collapse in seven of 10 backcrosses, including in several reciprocally compatible backcrosses that provided further proof of a sporophytic SI system. Additionally, a χ2 test showed that the data fit a sporophytic SI model with S allele dominance operating in pollen and pistil. Assuming that S allele dominance is widespread within Echinacea purpurea, it should be possible to produce inbred lines by making successive generations of full-sib crosses.

Abstract:

Abstract Echinacea purpurea (L.) Moench, a member of the Asteraceae family, is a plant rich in flavonoids, essential oils, phenolic compounds, saponins, polysaccharides and glycoproteins. The aim of the study was to evaluate the protein content in dried roots of Echinacea purpurea (L.) Moench after homogenization of roots with liquid nitrogen, extraction in 0.01 mol L-1 phosphate-buffered saline (PBS) and purification followed by fractionation of proteins using gel filtration chromatography. Total concentration of proteins was measured using the Bradford method, and evaluation of the molecular mass of proteins was accomplished by applying the SDS-PAGE gel electrophoresis. The Bradford assay revealed that the highest concentration of proteins in fractions collected after gel filtration chomatography was 4.66–6.07 mg mL-1. Glycoproteins, alkamides and polysaccharides in roots of Echinacea purpurea (L.) Moench are chemical compounds that are responsible for their immunomodulatory properties. However, information about the difference of protein contents in fresh and dried roots of E. purpurea is insufficient.

Abstract:

Echinace from the Asteracea family has been among the top 10 marketed herbs in North America and Europe. So far, only a limited amount of Echinace originate from commercial cultivation. Echinacea purpurea has been commercially cultivated in the United States since the mid 1970s, in Russia since 1935, while in Europe since the 1960s. However, there has been no published information in the English language on methods of cultivation, expected yields, limiting factors, nutrient requirements, and the optimum plant development stage to obtain maximum yield and concentration of the biologically active substances for pharmaceutical and cosmetic processing. The objective of this investigation was, therefore, to study the general distribution of major nutrients and biologically active substances and the relationship between the two groups, and the pattern of the accumulation of cichoric acid, echnacoside, isobutylamides (tetraenes) and essential oil in commercially cultivated Echinacea purpurea. There was a significant variation in the content of essential oil, cichoric acid, and isobutylamides (tetraenes) in different organs and stages of the plant development. Similarly, the difference in the distribution of N, P, K, Ca, Mg, and Fe in different organs and developmental stages is demonstrated. The correlation between the content of the active substances and nutrients is demonstrated, while recommendations for an optimum harvesting stage and date are made.

Abstract:

Seeds of tickseed (Coreopsis lanceolata L.) and purple coneflower [Echinacea purpureo (L.) Moench] were primed in aerated solutions of a 50 mm potassium phosphate buffer at 16C. C. lanceolata seeds were primed for 3 or 6 days; E. purpurea seeds were primed for 6 or 9 days. Seeds were vacuum-stored for 2 months immediately after priming. Identical treatments were imposed on open-stored seeds just before the termination of the storage duration, thus producing four treatments: a vacuum-stored control, an open-stored control, primed vacuum-stored seed, and seed primed after open storage. Although priming significantly improved the performance of C. lanceolata seed, vacuum storage alone also significantly increased the speed of germination and final germination. The advantage of priming was diminished during 2 months of vacuum storage of E. purpurea, but priming enhanced germination as compared with the open-stored nonprimed control. There was little difference between the performance of E. purpurea seeds both primed and vacuum-stored. and the vacuum-stored control.

Improved descriptions and detailed drawings of the most important anatomical characters of the roots of Echinacea purpurea (L.) MOENCH, E. angustifolia DC., E. pallida (NuTT.) NUTT., and of Parfhenium integrifolium L. are presented. The anatomy of the rhizome of E. purpurea, which was detected in commercial samples, and of the root of E. atrorubens NUTT., another known adulteration for pharmaceutically used Echinacea-species, is documented for the first time. The possibilities and limitations of the identification by means of microscopy are discussed. The anatomical differences between the roots of E. angustifolia, E. pallida and E. atrorubens are notsufficient for differentiation, however, root and rhizome of E. purpurea and the root of Parthenium integrifolium appear well characterized. Because of the highly similar anatomy the microscopic proof of identity and purity of crude drugs of Echinacea must be done with uncomminuted material and the examination of cross sections.

Abstract:

Organic production of one of the most popular botanical supplements, Echinacea, continues to expand in the U.S. Echinacea seeds typically show a high degree of dormancy that can be broken by ethephon or gibberellic acid (GA), but these methods are currently disallowed in organic production. In order to determine the efficacy of nonchemical seed treatments, we evaluated the effect of varying seed source and supplying light, with and without cold-moist stratification, on seed germination of the three most important medicinal species of Echinacea, E. angustifolia DC, E. purpurea (L) Moench, and E. pallida (Nutt.) Nutt. Treatments included cold-moist stratification under 24 hours of light, 24 hours of dark, and 16/8 hours of light/dark to break seed dormancy. We found that germination was greater in the E. purpurea and E. pallida seeds from a commercial organic seed source compared to a public germplasm source. When seeds were not cold-moist stratified, 16 to 24 hours light increased germination in E. angustifolia only. Echinacea angustifolia, E. purpurea, and E. pallida seeds that were cold-moist stratified under 16 to 24 hours of light for 4 weeks had a significantly greater percentage and rate of germination compared to seeds germinated in the dark. Therefore, cold-moist stratification under light conditions is recommended as a method to break seed dormancy and increase germination rates in organic production of Echinacea.

Abstract:

Consumption of Echinacea, one of the most popular botanical supplements, continues to expand in the United States. In addition, organic herbal products have captured a large share of the botanical supplement market. We evaluated commercial organic production of the three most-important medicinal species of Echinacea, E. angustifolia DC, E. purpurea (L) Moench., and E. pallida (Nutt.) from two seed sources. Plants were grown in the field for 3 consecutive years. We found that, during the first year, screen cages were associated with enhanced post-transplanting establishment. Growth of E. angustifolia was not affected by either production system or seed source after 3 years, and yields were equivalent for years 2 and 3 for this species. Growth of E. purpurea was affected by production system, but not by seed source, during the first 2 years. In year 3, neither seed source nor production system affected growth of E. purpurea. Yield of E. pallida was greater in the open field the first year; no difference between production systems was found during the second; and, by the third year, plants growing in screened cages produced more than plants growing in the open field. Production system affected yield of E. purpurea only during year 2, and yield was greater in the open field than in screened cages. Echinacea plants in the open field, however, were more affected by aster yellows disease, with an infection rate of 17% for E. purpurea in the open field compared to 3% under screen cages. Based on these results, in areas of aster yellows incidence, excellent Echinacea root yields can be obtained under screen cages using organic seeds.

Abstract:

The aim of this study was to develop a delivery system for polyphenols from an extract of Echinacea purpurea leaves, based on liposomes. Liposomes loaded with Echinacea purpurea were prepared and characterized in terms of entrapment efficiency, size, polydispersity index, stability and release behavior. Results showed good entrapment efficiency, small sizes, low polydispersity index and good stability over 90 days at 4oC. Also, the liposomal formulations presented reduced burst release and slow release of polyphenols compared with free extract. Therefore, liposomes offer a great potential in the development of drug delivery systems for polyphenols.

Abstract:

Chromosome karyotypes of the most commonly cultivated and medicinally used Echinacea taxa, E. angustifolia DC. var. angustifolia and E. purpurea (L.) Moench., were analyzed. The chromosomes of both taxa are medium in length, ranging from 4.12 to 5.83 μm in E. angustifolia var. angustifolia and 3.99 to 6.08 μm in E. purpurea. No abrupt length changes in the chromosomes were noted. The karyotypes of the two species are generally similar, but a distinguishable feature exists in one pair of chromosomes. The centromere of chromosome pair 10 is subterminally located in E. purpurea, but terminally located in E. angustifolia var. angustifolia, which can be readily recognized in mitotic metaphase cell plates. This finding may provide useful information for Echinacea evolutionary, genetic, and breeding studies.

Abstract:

The rising interest in medicinal plants has brought several species of the genus Echinacea to the attention of many scientists. Echinacea angustifolia , E. pallida , and E. purpurea are the most important for their immunological properties, well known and widely used by the native Americans. The three species are easily distinguishable on the basis of their morphological characteristics, but it would be difficult, if not impossible, to distinguish them in commercial preparations of ground, dry plant parts of E. purpurea (the most valuable species for chemotherapeutic properties) mixed with the other two species. Species-specific molecular markers could be useful to address this issue. In the present work, using fresh material collected from cultivated Echinacea spp., AFLP analysis was used to discriminate the three species and to detect species-specific DNA fragments. By using 14 primer combinations it was possible to detect a total of 994 fragments, of which 565 were polymorphic. Overall, 89 fragments were unique to E. purpurea, 32 to E. angustifolia, and 26 to E. pallida. E+CAC/M+AAT or E+CAC/M+AGC alone provided 13, 9, and 4 or 7, 5, and 5 specific fragments for E. purpurea, E. angustifolia, and E. pallida, respectively. A validation trial to confirm the results was carried out on bulked samples of 23 accessions covering most of the genetic diversity of the three species. The results are discussed in terms of practical applications in the field of popular medicine, detecting frauds, and implications for the genus Echinacea.

Abstract:

Plants of the genus Echinacea have received extensive research attention, yet relatively little is known about the fruit (cypselae) of this economically important genus. The goal of this study was to investigate and compare the cypselae of four species of Echinacea: E. purpurea (L.) Moench, E. angustifolia DC., E. pallida (Nutt.) Nutt., and E. paradoxa (Norton) Britton, with respect to chemistry and germination. The phytochemical content of various fruit fractions was analyzed by high performance liquid chromatography with diode-array detection, identifying several alkylamides and caffeic-acid derivatives of medicinal value in all of the tissues. Alkylamides were most concentrated in the perianth and glands, whereas phenolics were generally enriched within the seed. Germination studies of intact cypselae and de-coated seeds demonstrate that the influence of cypsela coatings on germination depends on the growth environment. Removal of the perianth and pericarp resulted in decreased germination in soil, but significantly improved the germination of seeds of all species when sown in a sterile agar medium. In contrast, a higher percentage of intact cypselae of E. purpurea, E. angustifolia, and E. pallida germinated in soil than in sterile agar. These results suggest an ecophysiological role for phytochemicals in seed germination and will inform the cultivation and breeding of less common Echinacea species as well as the development of new products from currently unused plant material.

Abstract:

Current field cultivation and wild-harvest methods for the medicinal plant Echinacea are struggling to meet the requirements for a high-quality, uniformly produced crop for human consumption. To help meet this challenge, the potential of using a greenhouse production system for Echinacea production was explored. Echinacea purpurea (L.) Moench and angustifolia DC. var. angustifolia plants were grown in three types of greenhouse production systems: (1) deep flow solution culture (D), (2) pots with either Pro-Mix (P) or (3) sand (S). Plants were irrigated with one of three nutrient solutions containing NO3−/NH4+ ratios of 7:1, 5:1 or 3:1, respectively. The plants grown in the Pro-Mix and the sand systems were either well-watered or subjected to periodical water stress. The results obtained after 12 wk of growth showed that Echinacea root production in the greenhouse systems was comparable with or better than that in the field. Based on root and total biomass production, the Pro-Mix system was the best production system for both E. angustifolia and E. purpurea. In most cases, the NO3−/NH4+ ratio did not have significant effects on the growth of either species. When effects were seen, however, higher NO3−/NH4+ levels generally resulted in greater leaf area, root and total biomass, and a higher root/shoot ratio. Mild periodic water stress did not affect the root/shoot ratio or the root biomass in either species. The application of a periodic water stress reduced leaf area of both species, but a reduction in total biomass was only observed in E. purpurea. Key words: Echinacea, greenhouse production, hydroponic production, medicinal plant, NO3−/NH4+ ratio, water stress

Abstract:

AbstractWeed management is a major constraint in organic production. It can be expensive and time-consuming and severe crop yield losses may be incurred when weeds are not adequately controlled. Research on organic weed management (OWM) in herb and vegetable production is increasing internationally, although in Australia very little work has been done to assess current OWM knowledge among growers, and to test the efficacy and cost effectiveness of the weed management practices used by organic growers. The effect of hand weeding, tillage, hay mulch, pelletized paper mulch (PP) and an unweeded control treatment on weed growth, crop growth and cost effectiveness were evaluated in several field trials on the Northern Tablelands of New South Wales using lettuce (Lactuca sativa L.) and echinacea (Echinacea purpurea Moench. [L.]). In echinacea, hand weeding, hay mulch and PP reduced weed growth by at least 90% compared with the control, while tillage reduced weed levels by about 50%. The more expensive weeding methods such as hand weeding and hay mulch (AU$9600 and 8900 ha−1 respectively) produced higher yields, while the cheaper methods such as tillage ($4000 ha−1) had low crop yields and were therefore 25–50% less cost effective. In lettuce, weed growth was reduced by 96% for hand weeding and PP compared with the control, 85% for hay mulch and 66% for tillage. Weed management was cost-effectively achieved using cheaper weeding methods such as tillage ($985 ha−1) compared with more expensive methods such as hand weeding and hay mulching ($4400 and 7600 ha−1 respectively). PP had lower yields and was expensive ($12,500 ha−1) and was usually not cost effective in these trials. The results highlight several important advantages and disadvantages of currently used OWM methods in the field.

Abstract:

Relevance. A wide range of pharmacological effects of tansy and Echinacea purpurea determine the continuing interest in the study of these cultures. Medicinal crops contain not only a large number of biologically active substances, but also trace elements necessary for normal growth and development. Agronomic bio-enrichment of medicinal raw materials allows you to increase productivity, manage product quality in the direction of enhancing the pharmacological action. Thus, the aim of the work was to study the effect of various doses of zinc acetate on the productivity of two medicinal crops of tansy and Echinacea purpurea.Material and methods. Studies were conducted from 2012 to 2018 on meadow-chernozem soil of the southern forest-steppe of Western Siberia. As objects of research, perennial medicinal crops were chosen – Tanacetum vulgare L. and Echinacea purpurea L. Zinc fertilizers were applied in the background (N125, N135P45K45) used in acetate form.Results. The introduction of zinc fertilizers into the soil contributed to an increase in the yield of medicinal crops in the conditions of the south of Western Siberia. It was revealed that the maximum yield was observed on the variants of 0.75 MAC Zn (Tanacetum vulgare L.) and 0.5 MAC Zn (Echinacea purpurea). Thus, tansy was more responsive to the use of micronutrient fertilizers. The studies established a high correlation relationship (r = 0.88–0.99) between yield indicators and doses of zinc added. The obtained optimal doses of zinc fertilizers (60 and 21.4 kg / ha) can be recommended for growing these crops in order to increase their productivity.

Abstract:

Seeds of tickseed (Coreopsis lanceolata L.) and purple coneflower [Echinacea purpurea (L.) Moench] were primed in aerated solutions of distilled water or 50 or 100 mM salt (potassium phosphate, pH 7.0) at 16C for 3, 6, 9, or 12 days. Coreopsis seeds primed in the 50 mM buffer germinated the most rapidly and uniformly, and, under stress conditions in the greenhouse, resulted in a faster-growing, more-uniform crop than other treatments. Seeds primed in distilled water and the 50 mM buffer germinated faster and at higher rates at suboptimal temperatures in the laboratory than nonprimed seeds. Priming of Echinacea purpurea seeds for 6 or 9 days in distilled water or in the 50 mM buffer resulted in faster, more-uniform germination than other treatments. Seedling emergence under stress conditions was improved by all priming regimes, with best emergence occurring in treatments that lasted > 3 days. Priming also increased germination rates of E. purpurea at suboptimal temperatures in the laboratory.

Вихідними даними для розрахунків слугують показники довжини і ширини листковоїпластинки, їх кількість, а також сума температур вище 5 0С і кількість діб від сівби. On the basis of long-term researches of Purple Coneflower (Echinacea purpurea (L.) Moench) variety «Zirka Mykoly Vavylova» and Pale Coneflower (Echinacea pallida (Nutt.) variety «Krasunja Preriy» for the first time ever there were developed and patented the methods for determining the efficiency of plants in pregenesic period of ontogeny. The foundation of methodology was made on the studies of regression models with high coefficients of determination which allow to make the estimation of aerial parts and root system productivity for the whole growing season without damaging the plants. The input data for the calculation are the indicators of the length and width of the leaf blade, the amount and the sum of temperatures above + 5 ºC and the number of days from sowing.

Abstract:

Цель исследования – определение эффективности влияния экстрактов эхинацеи пурпурной (Echinacea purpurea) и ромашки аптечной (Matricaria chamomilla) в кормлении кроликов на физико-химические и функционально-технологические свойства мяса. Задачи исследования: определить химический состав мяса кроликов после скармливания фитобиотических кормовых добавок, определить содержание аминокислот средней пробы мяса (фарша), изучить функционально-технологические свойства исследуемых образцов мяса кроликов. Исследование проводили на базе Федерального государственного бюджетного образовательного учреждения высшего образования «Кузбасская государственная сельскохозяйственная академия». На первом этапе исследования провели формирование групп молодняка кроликов калифорнийской породы по принципу пар-аналогов. С 70-дневного возраста животным опытных групп давали дополнительно к рациону экстракты эхинацеи пурпурной (Echinacea purpurea) и ромашки аптечной (Matricaria chamomilla). Кролики получали экстракт лекарственного растения в составе комбикормов в количестве 50 % от суточной нормы в утреннее время и 50 % в вечернее, согласно схеме опыта. В среднем кролику требуется 70–100 г сухого корма и 70–80 г сена в сутки. Продолжительность эксперимента составила 30 дней. Доказано, что экстракты эхинацеи пурпурной (Echinacea purpurea) и ромашки аптечной (Matricaria chamomilla) положительно влияют на мясную продуктивность, состав и физико-химические показатели мяса кроликов. Оценили показатели среднесуточного потребления аминокислот и заключили, что образцы мяса опытных групп кроликов, употреблявших в составе рациона комовую добавку, удовлетворяют суточную потребность при потреблении 100 г мяса на 41,12 и 41,76 % соответственно, при этом мясо кроликов контрольной группы удовлетворяет суточную потребность на 38,38 %. Мясо кроликов исследуемых образцов обладало высокими функционально-технологи-ческими свойствами.
