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.

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.
