Regulátory rostlinného růstu a jejich možné využití při produkci okrasných dřevin
 Hajdová, Pavla
At the experimental plot in the area of Faculty of Horticulture in Lednice was created attempt to determine the effect of growth regulators on the model plant ( Spiraea bumalda 'Anthony Waterer ' ) growing in containers. The purpose was according to morphological and physiological parameters to determine whether the application of growth regulators reduce the effect of stress factors affecting the quality of plants . Growth regulators for this experiment were - abscisic acid, 24 - epibrassinolid, kinetin and spermine (each at three different concentrations ) . It was a total of 12 variants and one control. Of the morphological parameters were evaluated: weight fresh biomass, weight of dried biomass, area of leaf, length of shoots, root collar diameter . Of the physiological parameters were evaluated - index the content of chlorophyll in leaves and chlorophyll fluorescence . The obtained data were statistically analyzed and then compared the effect of various phytohormones. The resulting effect in terms of importance for nursery production was the effect of 24 -epibrassinolidu the most measured parameters.
