Experiments were carried out in the experimental station “Marcelin” of Poznań University of Life Sciences in 2006. The objective of this study was to compare eight dill cultivars in order to determine their usefulness for cultivation in containers in different lighting conditions (PPFD -100 and 75 μmol·m-2·s-1).The following cultivars ‘Amat’, ‘Ambrozja’, ‘Herkules’, ‘Krezus’, ‘Kronos’, ‘Lukullus’, ‘Skaner’ and ‘Szmaragd’ were compared. In the first week of cultivation, higher plants and greater biomass were obtained in the cultivation at 100 µmol. m-2.s-1 in comparison with plants growing at 75 µmol. m-2.s-1. After four weeks of growth, no differences in the parametric assessment of plants growing at 100 µmol. m-2.s-1 and at 75 µmol. m-2.s-1 were observed. ‘Ambrozja’ cultivar was characterized by the highest growth dynamics and value of LAI index, while ‘Skaner’ by the lowest. The performed experiments showed that ‘Ambrozja ‘cultivar is the most suitable one for cultivation in containers.
The aim of this paper is to overview and analyse existing methods for estimation of tree geometric parameters from Airborne Laser Scanning (ALS) data in the context of their possible application for agricultural areas. A detailed description of the estimation methodology proposed by various research groups is presented, including Canopy Height Model creation, tree identification, crown delineation in 2D and 3D, estimation of tree height, crown base height, crown diameters and crown volume. Efficiency and drawbacks of presented methods are identified. It is also analysed, whether the existing methods, originally developed for forestry areas, are suitable for agricultural trees.
Scutellaria barbata D.Don is an important medicinal plant used in traditional Chinese phytotherapy. It has been recently acclimated with success to Central European climatic conditions. Here, we present the results of chromatographic studies of herb collected from plants cultivated in Poland with respect to polyphenols compounds. By means of TLC and HPLC analyses we were able to detect several flavonoids: baicalein, luteolin, wogonin, apigenin, quercetin and kaempferol as well as ellagic and p-coumaric acids. From this study we can conclude a satisfactory quality of the crude drug from acclimated plants.
Morphological characterisation and the evaluation of growth and development of cultivated Primula veris L. plants were done according to different origin of seeds which the cultivated populations were started from and to two types of row spacing applied in the experimental plots. For each plant the number of leaves per plant and the rosette diameter were determined. At the flowering phase the number of scapes per plant, as well as the numbers of buds, flowers and fruits per plant and per scape were determined. The level of saponin content, converted to primulic acid, in rhizomes and roots of cowslip plants from natural and cultivated populations was assessed by means of the densytometric method. The growth and development of cowslip plants under cultivation conditions were more intensive at the plant spacing of 40 x 30, whereas fewer leaves dried on plants at the spacing of 30 x 15. The number of leaves and the diameter of leaf rosettes of the studied plants had a significant influence on the number of scapes per plant as well as on the number of flowers and fruits per plant. The saponin content in the underground organs of cowslip plants increased by 0.8-4.0% after transferring plants from natural habitats to cultivation conditions.
The quality-quantity analyses of volatile compounds in the essential oils of lovage of the Amor variety grown in Poland resulted in identifying more than 90 compounds in the essential oils from different botanical parts of the plant. The methods used were gas chromatography and mass spectrometry. There are some differences in the quantity of compounds in particular botanical parts, as the major compounds of root-oil and seed-oil are phthalides (90% and 54%, respectively), while the major compounds of leaf-oil and stem-oil are terpinyl acetate (48% and 57%, respectively) and ß-phelandrene (17% and 11%, respectively).
