Phytohormones as indicators of the degree of damage in birch (Betula pendula)

Popis výsledku v původním jazyce

In the study of the cyclophysis of birch (Betula pendula Roth.) a higher ethylene production and decrease of ethane production were found during budbreak and growth of one-year-shoots. After the beginning of endogenous dormancy in August, ethylene production was decreased while ethane production and the level of abscisic acid increased. One-year-shoots from heavily damaged birch stands produced significantly more ethylene, simultaneously with lower ethane production and revealed lower content of abscisic acid in buds at the dormancy onset compared to one-year-shoots from the stands which were not exposed to stress load. The stressed birches according to the degree of damage produce lower amounts of ABA in response to stress (cold stress in April) and during dormancy onset. In contrary, at the end of the dormancy the level of ABA in undamaged birches decreased to the lowest level.
