Název v původním jazyce

The changes in ethylene production, abscisic acid and indolyl-3-acetic acid contents as markers of birch stress and damage under the influence of CEPA and H2SO4 treatments

Popis výsledku v původním jazyce

In the present work the changes in endogenous ABA (abscisic acid), IAA (indolyl-3-acetic acid) contents and in ethylene production were observed after stress simulation by treatment of birch with CEPA (2-chloroethylphosphonic acid) - 1% solution of Flordimex and/or 0.1 N solution of H2SO4. At the same time the interactions between the changes in the phytohormone contents evoked by stress and endogenous bud dormancy of birch were described. The content of ABA and IAA was studied in leaves and nodes (or buds) of birch, 1, 24 and 48 hours and 3 and 6 weeks after CEPA and H2SO4 treatments, and at the same time the production of ethylene by the intact plant. A higher content of ABA in leaves and nodes was observed 1 hour after treatment both CEPA and H2SO4.The content of IAA was low in leaves, in nodes the content of IAA was low after CEPA treatment, higher after H2SO4 treatment.
