Dynamics and some characteristics of natural free cytokinin content in growing apices of apple tree shoots during the vegetative season

Abstract

The changes of content and some chromatographic characteristics and biological activities of natural free cytokinins were studied during the vegetation season in the growing apices of apple tree shoots. Biological cytokinin activity was discovered in two groups of compounds differing in the time of their biological actions. Rf values and in the time of their maximal content in the growing apices. The time of maximal content was in accordance with their biological activity.

Abstract

Byly studovány změny v obsahu, chromatografické charakteristiky a biologická aktivita přirozených volných cytokininů během vegetační doby v rostoucích vrcholech jabloňových výhonů. Biologická cytokininová aktivita byla nalezena u dvou skupin látek, které se lišily ěasem své biologické akce, hodnotou Rf a dobou maximálního obsahu v rostoucích terminálech. Doba jejich maximálního obsahu se shodovala s dobou jejich biologické aktivity.
