Investigation of changes in phytohormone levels depending on effects of exogenous indole-butyric-acid and callus formation in the stem cuttings of some apple kinds (Malus sylvestris Miller).

摘要

In this study, the effect of exogenous indole-butyric-acid and callus formation on the total indole-3-acetic acid, gibberellic acid, zeatin and abscisic acid levels in cuttings stems of apple (Malus sylvestris Miller) kinds (Golden delicious, Starkrimson delicious and Misket delicious) were determined the variations before and after the treatment. Total indole-3-acetic acid, gibberellic acid, zeatin and abscisic acid levels of the callus stems in the all of apple kinds were higher than those of non-callus forming. There was also increasing determined in indole-3-acetic acid, gibberellic acid, zeatin levels of calli treated with indole-butyric-acid (2000 and 3000 mg L-1) and decreasing in abscisic acid.
