    Opis:
    Garden thyme is a very important essential herbal plant grown in Poland. As well as being able to regulate digestion processes, thyme herbage possesses disinfecting, expectorant, antioxidant, spasmolytic properties. Research has been launched to define the effect of NPK fertilisation on yielding, the content of essential oil as well as the mineral composition of garden thyme (Thymus vulgaris L.) herbage. The experimental factor consisted of NPK mineral fertilisation applied into soil at the following doses per hectare and proportions: A0 – without mineral fertilisation, A1 – 30 kg N + 22 kg P + 100 kg K (N:P:K was: 1:0.75:3.33), A2 – 60 kg N (30 kg N + 30 kg N) + 22 kg P + 100 kg K (1:0.37:1.67), A3 – 90 kg N (45 kg N + 45 kg N) + 22 kg P + 100 kg K (1:0.24:1.11). The experiment comprised 4 fertilisation objects with 4 replications, and the sowing area and the harvest area of 3 m2 plot-1. Nitrogen was applied in the form of ammonium nitrate twice: pre-sowing as well as after plant emergence. Phosphorus and potassium were used pre-sowing, in the form of triple superphosphate 40% and 60% of potassium salt, respectively. The doses of 152 kg NPK ha-1 (1:0.75:3.33) – A1 and 182 kg NPK ha-1 (1:0.37:1.67) - A2 showed the most favourable effect on the yield of fresh weight, air-dried weight and essential oil of herbage as well as the quality characteristics of the yields. The dose of 152 kg NPK ha-1 (A1), including 30 kg less nitrogen, was as favourable as that of 182 kg NPK ha-1 in terms of the content of air-dry weight of herbage, essential oil as well as mineral nutrients. Its application also resulted in a similar yield of essential oil. The application of 212 kg NPK ha-1 (1:0.24:1.11) was economically unjustified since, in general, it decreased the size of the yield of fresh weight of herbage and the values of its parameters studied.

    Opis:
    W pracy przebadano patogeniczność Fusarium avenaceum, F. culmorum i F. Equiseti dla tymianku właściwego. Testowane izolaty grzybów pochodziły z różnych gatunków roślin zielarskich. W laboratorium przebadano oddziaływanie płynów pohodowlanych oraz wodnej zawiesiny zarodników Fusarium spp. na zdolność kiełkowania rozłupek tymianku właściwego. W komorze klimatyzacyjnej, stosując metodę infekcji przez zakażoną glebę, badano oddziaływanie Fusarium spp. na wschody i zdrowotność siewek. Wykazano, że szkodliwość F. avenaceum, F. culmorumi F. equiseti dla tymianku właściwego wyraża się, bez względu na pochodzenie izolatów grzybów, hamowaniem kiełkowania rozłupek oraz wschodów i wzrostu siewek. Objawem porażenia jest nekroza kiełków i korzeni roślin. Każda z zastosowanych trzech metod sztucznego zakażania tymianku zapewniała bezpośredni kontakt grzybów z powierzchnią rozłupek oraz z kiełkami i korzeniami siewek. Jednakże do szybkiej oceny patogeniczności Fusarium spp. dla tymianku właściwego, należy polecić metodę przy użyciu płynów pohodowlanych, ze względu na obecność w nich toksyn wytwarzanych przez grzyby.
    The pathogenicity of Fusarium avenaceum, F. culmorum and F. equiseti to thyme was examined in present work. Isolates of tested fungi originated from various herbs plants. The effect of Fusarium spp. post-culture liquids and water suspensions of Fusarium spp. spores on germination of thyme schizocarps was studied in the laboratory. The effect of Fusarium spp. on the shooting up and healthiness of seedlings was carried out in the climatic chamber conditions using the method with infested soil. It was shown, that harmfulness of F. avenaceum, F. culmorum and F. equiseti to thyme, regardless of the origins of fungi isolates, was expressed by inhibition of schizocarps germination and by limiting of seedlings numbers and their growth. The symptoms of infection were a necrosis of shoots and roots. Each of the three used methods of artificial infection of thyme secured direct contact of with the surface of schizocarps, shoots and roots of seedlings. However the method with Fusarium spp. post-culture liquids should be recommended to the fast estimation of Fusarium spp. pathogenicity to thyme on account of occurrence of toxins, which are produced by fungi.

    Opis:
    In 2005-2007, in a field experiment, the yield and quality of the thyme herb of the Polish cultivar Słoneczko in organic farming were tested. The experiment was established on six different organic farms and one conventional farm in Poland. The following features were evaluated: fresh and dried herb yield, stem fraction in herb, essential oil content, and microbiological purity. Only from one organic farm in Słońsk thyme herb yield was higher compared with the yield from conventional cultivation, although it contained a high amount of stems. Organic thyme herb was characterized by a high content of essential oil. Evaluation of microbiological purity showed that herb contamination from both types of cultivation did not exceed the standard for raw materials treated with hot water.
    W latach 2005-2007 w doświadczeniu polowym zlokalizowanym w Polsce w sześciu gospodarstwach ekologicznych i jednym konwencjonalnym badano plonowanie, jakość surowca tymianku oraz przydatność polskiej odmiany Słoneczko do upraw ekologicznych. Oceniano następujące cechy: plon świeżego i powietrznie suchego ziela, udział łodyg w surowcu, zawartość olejku eterycznego oraz czystość mikrobiologiczną. Plon surowca tymianku pochodzącego z uprawy ekologicznej tylko z jednej lokalizacji (Słońsk) był większy niż z uprawy konwencjonalnej. Surowiec ten jednak charakteryzował się dużym udziałem łodyg. Surowiec tymianku pochodzący z upraw ekologicznych charakteryzował się wysoką zawartością olejku eterycznego, jednak była ona mniejsza niż ziela z upraw konwencjonalnych. Ziele pochodzące z uprawy konwencjonalnej zawierało najwięcej azotanów. Ocena czystości mikrobiologicznej surowca tymianku wykazała, że stopień zanieczyszczenia surowców zarówno z uprawy ekologicznej, jak i konwencjonalnej nie przekraczał dopuszczalnych norm dla surowców poddawanych działaniu gorącej wody.

    Opis:
    Introduction: Spice plants are a rich source of biologically active compounds. Processes of drying, limits the development of microorganisms and biochemical reactions in raw herbs, at the same time modifies their chemical composition. Objective: The aim of this work was to evaluate the effect of drying process of selected plants on their antioxidant potential and the content of biologically active compounds. Methods: The herbal materials thyme herb (Thymus vulgaris L.), sage leaves (Salvia officinalis L.) and rosemary leaves (Rosmarinus officinalis) were dried using two methods: convective (at 30° C), and freeze-drying. In both, fresh and subjected to drying processes herbs, changes in total polyphenol and antioxidant potential (with the DPPH radical), vitamin C (in the form of ascorbic acid) and chlorophyll pigments contents, were studied. Results: The highest content of polyphenols and vitamin C was recorded in rosemary, while sage was characterized by the highest content of chlorophylls. It was found that the drying processes caused large losses of vitamin C (ascorbic acid) and dyes in comparison to the fresh material. The highest losses of vitamin C occurred in convection dried sage (95%), while most was preserved in lyophilised thyme (losses 74%). Drying had also influenced the reduction of the content of chlorophylls with the largest loss of these compounds, at 94% observed in the freeze-dried rosemary. However, the content of polyphenols increased, underscoring a large impact on the antioxidant activity of herbs. Conclusions: Drying processes resulted in the release of phenolic compounds, so their content increased three to four times in the case of rosemary and sage. The largest increase was observed in the case of lyophilised thyme. Simultaneously, the antioxidant potential was significantly increased. Herbal droughts proved to be a rich source of antioxidant compounds with promising applications as a food additive.

    Opis:
    Thyme belongs to herbal plants, the yield and quality of which depend on biological factors, agrotechnical procedures and the way of processing and storage. Basic factor differentiating the biological value of plants is fertilization, including manure, as well as plant growth and development, which is significantly influenced by the pH of the substrate, in which the plants are grown. The aim of the study was to determine the effect of manure dose (12.5 and 25 g·dm–3) and calcium carbonate (5 and 15 g·dm–3) on the yield and biological value of thyme. The fresh thyme mass yield was changed under the influence of the factors used. The highest yield of raw material was recorded after using a high dose of manure and calcium carbonate. Significantly higher concentration of essential oil in thyme was found after feeding the plants with higher dose of manure. The inverse relationship was demonstrated for the amount of L-ascorbic acid that decreased with the increase in manure dose. Calcium fertilizers not only serve to regulate the acidity, but are also a source of calcium for plants. After applying a higher dose of CaCO3, significant increase in the yield of fresh thyme mass was observed and higher dry matter content was recorded

    Opis:
    The objective of the study was to perform micromorphological analyses of the secretory structures of leaves and stems of oil-bearing industrial plants from the Lamiaceae family such as lemon balm (Melissa officinalis L.), peppermint (Mentha × piperita L.), sage (Salvia officinalis L.), marjoram (Origanum majorana L., syn. Origanum dubium Boiss.), rosemary (Rosmarinus officinalis L.) and common thyme (Thymus vulgaris L.) using light microscope and scanning electron microscope. In addition, an estimation of the content of volatile substances in the plant species under study was performed using GC-MS, as well as the qualitative and quantitative analysis of essential oil, that is an important component in terms of the estimation of raw material applicability for use in the industry. In the epidermal cells of studied plants, 2 types of Lamiaceae-type glandular trichomes were identified: short- and long-stalked capitate glandular trichomes with single- and bicellular secretory capitulum, and peltate glandular trichomes with eight- and over a dozen-cell secretory capitulum. Capitate trichomes were densely distributed on the surface of the epidermis, while peltate trichomes were sparse, though regular, and were situated in depressions. Glandular trichomes were found more frequently on leaves than on stems. The cuticle of the abaxial of leaf was characterized in most cases by the occurrence of larger average diameter peltate trichomes compared to the cuticle of the adaxial side of leaf. Peppermint produced the largest structures accumulating essential oil on the leaves (average diameter of peltate trichomes – 78.48 µm on the adaxial side of leaf, up to 96.43 µm), while on the stem, the highest average diameter of the peltate trichomes was observed in sage (an average of 75.53 µm, up to 85.99 µm). The lemon balm was characterized by the presence of capitate and peltate trichomes with the smallest diameter (an average of 44.26 µm). Lemon balm was characterized by the greatest density of glandular trichomes compared to other plant species. Among the plants studied, the highest content of oil was noted in the case of thyme and peppermint (2.22% and 2.20% v/w, respectively), and the lowest in green parts of lemon balm (0.17% v/w). The isolated essential oils contained predominantly components from the groups of monoterpenes and sesquiterpenes, and it is the presence of those substances that determines the possibility of utilizing the plants studied for a variety of purposes.
