Involvement of auxin and cytokinins in initiation of growth of isolated pea buds
Original language description
Axillary buds from the second primary scale excised from 21-day-old pea (Pisum sativum L. cv. Vladan) plants were used as a model system for studying the release of buds from apical dominance. The isolated buds were transferred onto basal medium with orwithout a supplement of growth regulators and cultivated up to 24 h in short-term and up to 4 weeks in long-term experiments. In both sets of experiments endogenous IAA, cytokinins and the uptake of labe1led zeatin were analysed. The development of budswas monitored by image analysis, estimation of their weight, and by anatomical studies. Generative meristems were found in isolated axi1lary buds already in 21-day-old plants at the beginning of the experimental period. The onset of bud growth was recorded as soon as 2 h after the bud excision by image analysis. The bud growth was accompanied by a rapid transient increase of the endogenous lAA level within the first 2 h, fo1lowed by an increase of iPA within 24 h.
