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...
The antifungal properties of selected essential oils, i.e. lavender, mint, orange, spruce and thyme oils, were checked in vitro to fungi isolated from blue spruce (Picea pungens Engelm.) and its cultivar ‘Glauca’. The degree and extent of antifungal activity for essential oils listed above were tested on the following fungi: Acremonium tubakii, Anthostomella conorum, Arthrinium state of Apiospora...
The experiments carried out in 2006–2007 referred to the growth of marjoram plants, its yields and chemical composition depending on the plant density and harvest time. Four plant densities (setting spacing 20 × 40 cm, 30 × 30 cm, 30 × 40 cm and 40 × 40 cm) as well as two harvest times (beginning of flower bud forming and full blooming) were applied. The lowest density favored the plant tillering,...
One of the more important species of herbal plants, grown in many countries for medical and nutritional purposes is sweet marjoram. The marjoram herb is an abundant source of valuable biologically active substances and mineral components. Considering the vast application of this plant studies were undertaken on the assessment of growth and yielding of sweet marjoram, depending on harvest time. The...
One of the most important problems in horticultural seed science and technology nowadays is looking for new methods to improve seed quality. Especially interesting are the ones, in which compounds of natural origin are used. One of such groups is ethereal oils from plants. The commercial seed samples of lettuce (Lactuca sativa L. ‘Dumka’) were soaked in 9 different treatments of 5% alcoholic solution...
No-tillage cultivation using cover crops is an important part of sustainable horticulture, however there are only few date on this subject related to ‘Hamburg’ parsley. In two years` field experiment no-tillage cultivation using white mustard as a cover crop did not affect germination of ‘Hamburg’ parsley cv. Alba but further growth of no-tilled plants was slower. Yield of no-tilled plants with leaves...
Leaf celery (Apium graveolens L. var. secalinum Alef.) is a vegetable with spicy and medicinal properties. A study on the effect of seeding rate and irrigation on yield of two leaf celery cultivars: ‘Gewone Snij’ and ‘Green Cuttnig’, was carried out at the Felin Experimental Farm of the University of Life Sciences in Lublin during the period 2009–2010. Seeds were sown in the field in the last decade...
The biological value of fresh and dried spice material is strongly influenced by climatic and agronomic conditions as well as by genetic and ontogenetic factors. In the available scientific literature, few publications present the problems of growing herbal plants for direct consumption and discuss the biological value of fresh herbal material. Therefore, the aim of the present study was to evaluate...
In 2008–2010, in the field experiment, the yield and quality of lavender flowers in organic cultivation were tested. The experiment was established in four different locations in Poland. The following features were evaluated: fresh and dried flower yields, seed yield, weight of 1 000 kernels, essential oil content and its composition and microbiological contamination. Lavender flower yield from organic...
Chamomile is a valued medicinal plant of high economic importance and therefore agronomic practices in growing this plant are continually improved. One of methods to improve the quantitative and qualitative parameters of herbal raw material can be the application of foliar sprays (growth stimulators, foliar fertilizers, Effective Microorganisms). Row spacing, which has an effect on the use of fertilizers...
Six coriander accessions of different origins were grown on an experimental field in Mošorin, Serbia during 2014. The GC/MS analysis of the essential oil showed that the major components in all samples were linalool (69.3–72.0%), γ-terpinene (6.0–9.6%) and α-pinene (6.7–8.2%), while other compounds were present at less than 5%. Antifungal activity of coriander oils against two phytopathogenic fungi...
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...
Seed infection with Alternaria spp. is an important source of severe carrot diseases. The aim of the study was to evaluate the effects of carrot seed treatments with acetic acid, grapefruit extract and volatile compounds of fir (Abies alba Mill.) and thyme (Thymus vulgaris L.) essential oils on their germination, vigour and health. Seeds of two samples were soaked for 30 min in 0.5, 1 and 2% acetic...
Essential oils from the leaves, stems and flowers of Postia puberula at the flowering stage were analyzed using GC and GC/MS. The results showed that leaves are abundant of cis-3-hexenyl benzoate (10.75%), benzyl benzoate (8.16%) and caryophyllene oxide (8.12%). The main compounds of stems were benzyl benzoate (21.92%), E-nuciferol (11.58%) and dibutyl phthalate (7.08%), while major components of...
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...
The study aimed to determine agronomic characteristics and essential oil components of different basil ecotypes in semi-arid climatic conditions of South Eastern Anatolia, Diyarbakir, Turkey. Two-year harvest data about fresh and dry herb yield, dry leaf yield, essential oil content and its components from the plants of year 2015 and 2016 was analyzed in this study. Essential oil components were detected...
Origanum dubium is a valuable wild oregano species of the natural flora of Antalya, Turkey. In this study, we extracted essential oil (EO) by hydro-distillation of the aerial parts of selected O. dubium chemotype with highest EO content, and analyzed by gas chromatography/mass spectrometry. Carvacrol was the primary component (85.9%) among 24 different compounds in the EO. The volatile test showed...
Murraya koenigii L. (family: Rutaceae), commonly referred to as curry leaf, is a highly valued plant due to its aroma and medicinal features. Two dominant AM species Glomus mosseae and Acaulospora laevis were isolated from the rhizospheric soil of M. koenigii. A pot experiment was performed to verify the interactive potential of G. mosseae and A. laevis alone or in combination with Pseudomonas fluorescens...
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...
