Vplyv vybraných faktorov na kvalitu škôlkarskej produkcie
Burgová, Jana
In the years 2008 - 2010 was realized trials with goal to influence the properties of the growing medium so, as the internal and external quality model plant (Viburnum opulus L.) grown in containers was significant increase. The whole of experiment was annually divided into equally two blocks, with different irrigation rates, which were also observed micro--climatic parameters both irrigation regimes. Was studied as well the influence of addition of soil conditioners on the properties of the growing medium. External quality of grown plants was assessed on the basis of morphological parameters (plant height, number of shoots, root collar diameter, dry matter of above-ground and root zone of plants and visual assessment of the root system) and internal quality based on the evaluation of physiological parameters (stomatal conductivity, chlorophyll fluorescence and chlorophyll content in the leaves). From the soil conditioners was investigated the impact of three commercially available agents with different composition and mode of action. It was a Hydrogel, TerraCottem and Agrosil LR. The properties of the growing medium, was affected by soil conditioners additive into the growing medium (peat--bark medium RKS II), but not enough for increase the quantitative parameters of cultivated plants, even the selected parameters in comparison with the control variant in both irrigation regimes were positively influenced, in order Hydrogel, Agrosil LR and TerraCottem
