摘要：

This work was aimed on the role of cytokinins in regulation of cotyledonary bud outgrowth in intact pea (Pisum sativum L.) plants. It is well known that application of cytokinins to the cotyledonary buds of intact plants activates their outgrowth. Here we show by immunolocalization rapid polarization of PIN1 proteins in the cytokinin treated buds, on contrary to untreated buds. It is therefore obvious that cytokinins directly influence polarization of PIN1 proteins and the subsequent canalization of the polar auxin transport from the buds enabling their outgrowth.
