The yield and composition of essential oil obtained from the fruits of coriander (Coriandrum sativum L.) cultivated in Poland were investigated. Experiments were carried out by means of the hydrodistillation method using Clevenger and Deryng apparatus. No effect of the apparatus’ construction on the essential oil yield was observed during a 2-h process (yield of 1.62%). The composition of the coriander...
This study evaluated the effect of Pseudomonas strains and arbuscular mycorrhiza fungi (AMF) in enhancing strawberry yield and phenolic and antioxidant capacity on a phosphorus (P) deficient calcareous soil. The experiments were conducted in three replicates with six treatments (four Pseudomonas strains, AMF and control) and three rates of P-fertilizer (0, 75, 150 kg P ha–1). Application of higher...
Peppermint (Mentha piperita L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Copper is an essential micronutrient for normal plant growth and metabolism.The aim of this study was to examine the effects of copper sulphate and copper nanoparticles on morpho-physiological traits and essential oil composition of peppermint. Seven treatments of copper...
Winter oilseed rape cultivars (open-pollinated variety, four composite hybrids, one restored hybrid and the CMS ogura line) were tested during two crop seasons of 2002/2003 and 2003/2004 in field trials at two locations in western Poland. The objectives of the present study were: to determine the variability of yield and the most important phenotypic traits of different types of winter oilseed rape...
The genus Actinidia was established by LINDLEY in 1836. The most recent systematic revision of Actinidia distinguish about 54 different species 52 of which occur naturally in China (44 of it are endemic). Recently Actinidia fruit has become famous for its nutritious, especially high content of vitamin C, and is evaluated as a healthy fruit. The results from the introduction of Actinidia species in...
The study evaluated three biotypes of cherry silverberry (obtained from the Institute for Fruit Growing in Samokhvalovitchy in Belarus) for cultivation under the conditions of north-eastern Poland in comparison to the form reproduced and cultivated at the University of Warmia and Mazury in Olsztyn. It was demonstrated that the natural conditions of Olsztyn permit cultivation of the examined cherry...
This particular study deals with the impact of pre-sowing nanotube-based seed treatment technology on rapeseed (Brassica napus) growth and yield. During field tests we identified a significant yield increase as a result of applying the pre-sowing nanotube-based seed treatment technology. The main treatment agents were physiologically active nanochips consisting of carrier matrix nanotubes with eliciting...
The purpose of this work was to determine the impact of weather conditions during the spring and summer growth of winter triticale on the yield and content of nutrients in its grain. The research results were achieved from a controlled field experiment carried out at the Experimental Station of the University of Warmia and Mazury in Olsztyn, located in Tomaszkowo near Olsztyn (53o42’ N; 20o26’ E)...
