【 摘 要 】

Within the gene pool collected at the Department of Breeding and Propagation of Garden Plants of the Faculty of Horticulture, Mendel University of Agriculture and Forestry in Brno, in Lednice we established experimental plots with some selected less known tree species - quince (Cydonia oblonga Mill.), sea buckthorn (Hippophäe rhamnoides L.), Cornelian cherry (Cornus mas L.) and honeysuckle (Lonicera caerulea subsp. edulis Turcy. ex Freyn.). The experimental plots were established in successive steps according to the availability of planting material and using conventional methods of cultivation. Evaluations are focused on selected growth parameters, phenology and commercial use of the fruit.The evaluations of the crown of quince showed differences in the size and shape. The variety Hemus had the largest crown volume (5.70 m3); the variety Blanár gave the highest harvest yields. The sea buckthorn varieties Polmix, Dar Katuni and Novosť Altaja produced the longest increments. The average weight of the fruit of the variety Leicora was 0.74 g. The varieties of Cornelian cherry also differed in the growth parameters; the highest shrubs were those of the variety Vyšegorodskij, which also produced the largest fruit – the average weight of the fruit was 4.85 g. The initial growth of selected varieties and genotypes of honeysuckle is different when compared to the fruit-bearing shrubs. Harvest data are in direct proportion to the size of the shrub. Fruit harvest began in mid-May and vegetation ended on 15 October.
