[Possibility of synchronizing cell populations in embryonic barley meristem].
Cell populations of the apical root parts, stem embryo and the leaf of barley seedlings are found to have different sensitivity to the synchronizing effect of 5-aminouracil, low temperature (+2 degrees C) and colchicine. The effect of 5-aminouracil and low temperature in the presence of colchicine proved to be the most effective in respect to synchronization of the root meristem cell populations. It also increases significantly the mitotic activity in the stem embryo and leaf meristems. The leaf meristem is more sensitive to low temperature as compared to the stem embryo meristem.
