Opis:
The aim of this study was to compare chemical composition of lemon balm and basil herbage grown in containers under fluorescent lamps (FL) and LED modules (LEDs). There were significant differences in the response of the species for the applied source of light. The content of essential oils was greater in basil herbage under fluorescent lamps, whereas the content of essential oils in lemon balm herbage was greater under LED lamps. The basil and lemon balm plants were characterised by high content of fructose and glucose and by very low content of sucrose. There were no significant differences in the nitrates content in basil and lemon balm herbage grown under either source of light. Both the basil and lemon balm herbage were found to have higher content of macroand micronutrients when they were grown under LEDs compared with fluorescent lamps. It can be concluded that the chemical composition of lemon balm and basil herbage was very varied and dependent on both the light and the species.
Światło jest jednym z czynników uprawy roślin mających wpływ na ich skład fitochemiczny. Jednak reakcja roślin na światło jest bardzo różna. Celem pracy było porównanie składu chemicznego ziela melisy i bazylii uprawianych w pojemnikach w zróżnicowanych warunkach świetlnych. Jako źródeł światła użyto lamp fluorescencyjnych (FL) oraz modułów diodowych. Stwierdzono istotne różnice w reakcji obu gatunków w zależności od zastosowanego światła. Zawartość olejków eterycznych w zielu bazylii była większa w uprawie przy lampach fluorescencyjnych, z kolei w zielu melisy była większa w uprawie pod modułami LED. Ziele bazylii i melisy charakteryzowało się dużą zawartością fruktozy i glukozy oraz bardzo małą zawartością sacharozy. Nie stwierdzono istotnych różnic w zawartości azotanów w bazylii i melisie dla obu źródeł światła. Zarówno bazylia, jak i melisa charakteryzowały się większą zawartość makro- i mikroelementów w uprawie pod diodami. Zawartość badanych substancji w zielu melisy i bazylii zależała zarówno od zastosowanego źródła światła jak i od gatunku.

Opis:
Celem pracy było określenie patogeniczności izolatów Fusarium avenaceum, F. culmorum i F. equiseti wyizolowanych z różnych gatunków ziół dla melisy lekarskiej. Przeprowadzono trzy różne testy patogeniczności. W warunkach laboratoryjnych określono oddziaływanie płynów pohodowlanych i wodnej zawiesiny konidiów Fusarium spp. na zdolność kiełkowania rozłupek melisy lekarskiej. Oddziaływanie Fusarium spp. na wschody i zdrowotność siewek przebadano w komorze klimatyzacyjnej, przy zastosowaniu metody infekcji przez zakażoną glebę. Izolaty badanych gatunków, bez względu na ich pochodzenie, powodowały nekrozę kiełków i korzeni roślin. Spośród stosowanych metod sztucznej infekcji najszybszą ocenę patogeniczności izolatów Fusarium spp. dla melisy lekarskiej zapewnia metoda z użyciem płynów pohodowlanych. Badane izolaty Fusarium spp. uznano za patogeniczne dla melisy lekarskiej na podstawie pozytywnych testów patogeniczności oraz ich częstego izolowania z rozłupek, korzeni i podstawy pędów zamierających roślin na plantacjach produkcyjnych.
The aim of the present work was to determine the pathogenicity of Fusarium avenaceum, F. culmorum, F. equiseti isolates, obtained from various species of herbs, to lemon balm. Three different tests of pathogenicity were carried out. The effects of Fusarium spp. post-culture liquids and water suspension of conidia on germination of lemon balm schizocarps were studied in laboratory conditions. The effect of Fusarium spp. on shooting up and healthiness of seedlings was carried out in climatic chamber conditions using the method with infested soil. All the isolates of fungi species studied caused necrosis of shoots and roots, regardless of their origins. From among three methods of artificial infection used, the method with Fusarium spp. post-culture liquids secured a fast estimation of pathogenicity the fungi isolates to lemon balm. The studied isolates of Fusarium spp. were recognized as pathogenic to lemon balm on the base of positive results in pathogenicity tests and on the base of their earlier isolation from different organs: schizocarps, roots and the bases of stems, taken from the plantations of lemon balm.

Opis:
The fight against weeds in the organic cultivation of herbal plants, both raw and for seeds, is a big challenge for growers. The paper compares the chemical (bentazon, 960 g·ha–1 and fluazifop-P-butyl, 150 g·ha–1) and nonchemical (scattering mustard seed meal in two doses 1.5 and 3.0 t·ha–1) control of weeds in the cultivation of lemon balm for seeds. Additionally, the influence of these factors on the yield of fresh herb and seeds of lemon balm and the sowing value of seeds was evaluated. The best method to control the weed infestation was to use mustard seed meal in an amount of 3.0 t∙ha–1. Scattering of mustard seed meal in that dose reduced the number and weight of weeds on average from two years of research by 52.1 and 60.2% in relation to unweeded control. Following methods were slightly less effective: bentazon and application of mustard seed meal in quantity of 1.5 t·ha–1. The largest yield of fresh lemon balm herb was collected from plots where mustard seed meal was used in an amount of 3.0 t∙ha–1. Seeds harvested from plots, on which mustard seed meal was used in a larger quantity was characterized by the lowest sowing value determined by the lowest energy and capacity of germination and the highest share of nongerminated seeds. Lowering the amount of used mustard seed meal to 1.5 t·ha–1 significantly improved their sowing value. Although this method was less effective in counteracting weeds than using larger dose, it provided comparable effects of reducing the number and weight of weeds in relation to chemical protection.

Opis:
Lemon verbena is cultivated mainly due to the lemon-like aroma emitted from its leaves that are utilized for most purposes. The chemical composition of the essential oil of lemon verbena was analyzed by GC/MS in July at pre flowering, in September at full flowering and in end of October at post flowering period. The in vitro antimicrobial activity of the essential oil, extracted from Lippia citriodora was tested against laboratory control strains belonging to the American Type Culture Collection (Maryland, USA) four Gram (+) and Gram (-) bacteria using the disc diffusion test. Antioxidant activity of the sample was determined by 1,1-diphenil-2- -picrly-hydrazil (DPPH) assay. Well-known antioxidant compounds such as ascorbic acid and α-tocopherol were used as standard. Results showed, among different harvest periods high fresh and dry herbage and dry leaf yields per plant were obtained from full flowering stage. Harvest periods were found to have a significant effect on the content of essential oil and the highest amounts of limonene, neral and geranial and measured as 31.15, 11.92 and 15.53%, respectively at full flowering stage. In all samples, the main constituents were limonene, neral and geranial constituting 46.03%–58.59% of the total essential oil yield depend on development stages. Lemon verbena essential oil was found to have antibacterial activity especially against Gram (+) microorganisms. In DPPH system, the moderate radical scavenging activity was exhibited. Therefore, L. citriodora has potential to be used as a natural antioxidant and antimicrobial agent in food processing.

Opis:
Lemon balm (Melissa officinalis L.) is a widely cultivated plant in Europe. Septoria melissae Desm. is the most important pathogen of lemon balm crops, which may cause serious yield loss by the severe leaf fall. As chemical control of the pathogen is restricted, alternative plant protection methods, like the use of tolerant varieties, should be taken under consideration. The goal of our work was to evaluate the susceptibility of three lemon balm varieties to Septoria leaf spot in field. The trials were carried out in 2016 and 2017 in Budapest-Soroksár, Hungary. Dynamics of infection showed characteristic sharp increase from the beginning of August in both years. The lowest infection levels were observed in cultivar ‘Lemona’. The disease incidence in the middle of August was 19% in the first year and 59% in the second year, while these values were over 40% and 70% in the other cultivars ‘Soroksári’ and ‘Quedlinburger Niederliegende’, respectively. The manifestation of symptomps was also significantly lighter on the ‘Lemona’ plants and they had the highest ratio of healthy leaves (81%) compared to the other cultivars. According to the data, weather conditions might modify the range of the differences among the cultivars. It was concluded that appropriate selection of varieties could be an effective and enviromental friendly plant protection method in the practice of lemon balm cultivation.

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.
