摘要：

Three-day-old seedlings of V. faba L. were put onto a diluted Knop''s solution containing the tested substances within the intentional concentration range for 7 days. In comparison with controls in plain nutrient solution, the DHPA [9-(2,3-dihydroxypropyl)adenine] treated plants revealed a suppression of shoot and root development. The main root growth was less sensitive than root branching. Eight hour exposure was sufficient to gain a distinct effect. Microscopically the block of mitosis and/or cytokinesis, the formation of binucleate cells and local tissue damage were revealed. Under the given conditions, the cytokinins were much more powerful inhibitors than DHPA, whereas adenine and adenosine were less so.
