Opis:
Doświadczenie przeprowadzono w latach 1997–1999 na plantacji dwuletniej. Badano wpływ terminu zbioru na plon świeżego ziela, powietrznie suchego ziela oraz powietrznie suchych liści szałwii lekarskiej (Salvia officinalis L.) odmiany ‘Bona’. Plantacja została założona każdorazowo w roku poprzedzającym badania poprzez sadzenie rozsady szałwii w ostatniej dekadzie maja (w 1996, 1997 i 1998 roku). Rozsadę posadzono w rozstawie 30×40 cm. Surowiec zebrano w dwóch terminach: w maju i we wrześniu. Wykazano istotny wpływ terminu zbioru na plon świeżego ziela szałwii lekarskiej w drugim roku użytkowania plantacji. Plon świeżego ziela uzyskany we wrześniu był większy (190,2 dt·ha⁻¹) aniżeli w maju (104,7 dt·ha⁻¹). Również zawartość olejku eterycznego w surowcu szałwii (liść, ziele) zebranym w drugim terminie (wrzesień) była większa niż w pierwszym (maj).
The study with sage (Salvia officinalis L.) cv. ‘Bona’ was conducted in the years 1997–1999. The effect of time of harvest on yield of fresh herb sage and yield of air dry herb, yield of air dry leaves sage. The experiment was conducted with sage two-year old. Sage transplants were planted in distance 30×40 cm. The plant material was harvested twice – in May and in September. Harvest date hat significant influence on the weight of fresh sage herb. Yield of fresh sage herb in September was bigger (190.2 dt ha⁻¹) than yield of fresh sage herb in May (104.7 dt ha⁻¹). The percentage quantity of the essential oil in the herb and leaves of sage was depended on the harvest date. The herb and leaves of sage in September had bigger the percentage quantity of the essential oil than in May. The percentage quantity of the essential oil in the leaves of sage, witch was collected in September amounted above 1.5%.

Opis:
Salinity stress is a serious problem in urban landscape of arid and semi arid regions. To overcome the adverse impact of salinity, the application of organic matter and plant nutrients in the growth media for improving the plant growth is essential. An experiment was conducted in order to determine the response of Salvia splendens to salinity levels and also the role of humic acid in the salt stress alleviation. In the current experiment, five salinity levels (0, 20, 40, 60, and 80 mM NaCl) and three humic acid (0, 100, 500 and 1000 mg/l) treatments were prepared. The effects of these treatments were investigated on some growth parameters, physiological characteristics and also biochemical compounds. The results indicated that the growth parameters decreased in saline-treated than control plants. Different salinity levels significantly affected relative water content, evaporation rate and also electrolyte leakage. Salinity caused the increase in proline, malondialdehyde, sugar content, DPPH, total phenol content and decrease in chlorophyll, compare to the control plants. Application of humic acid on Salvia splendens decreased the leaf area and plant height compared to the control plants. Thus, regarding the growth parameters, it is probable that the effect of humic acid on the biochemical compounds is similar to salinity effect. The findings suggest that sage is an ornamental plant sensitive to salinity and humic acid (in the studied levels) could not alleviate the negative effects of salt stress on this plant.

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.
