EFFECT OF EXOGENOUSLY APPLICATION SELECTED PHYTOHORMONAL SUBSTANCES ON THE PHYSIOLOGICAL AND MORPHOLOGICAL INDICATORS OF PHILADELPHUS X HYBRID IN CONTAINERS

Abstract JONÁŠ, M., SALAŠ, P., BALTAZÁR, T.: Eff ect of exogenously application selected phytohormonal substances on the physiological and morphological indicators of Philadelphus x hybrid in containers. Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 8, pp. 109-118 The experiment was established in order to eliminate the eff ect of stress factors acting on woody plants cultivated in containers. The timber Philadelphus x hybrid 'Mont Blanc'. The timber was in 1.5 l containers. The experiment was evaluated eff ect of exogenouse application of phytohormonal substances on select physiological indicators (stomatal conductance, chlorophyll fl uorescence and chlorophyll content), were measured three times during the vegetation. Morphological indicators (diameter of root neck, total length of shoots and number of shoots), were evaluated at the end of vegetation. Phytohormones aff ecting the impact of stress on plants were used for the purpose. Abscisic acid, 24-epibrassinolid, kinetin and spermine were applied by spraying the leaf in three concentrations (0.01 mg.l −
