The effect of nine newly synthesized asymmetric N,NЎд-substituted isonicotinoylsemicarbazides ЁC structure analogues of cytokinines on some physiological reactions typical of the cytokinines ЁC chlorophyll destruction in leaves of radish - Raphanus sativa L. and barley Hordeum vulgaris L., was investigated. It was found that all the studied compounds at concentrations of 0.1 M, 0.01 M and 1.0 ¦МM retained chlorophyll degradation and their activity was comparable and even exceeding that of the standards used: purine 4-PU-30 and phenylcarbamide benzyladenine cytokinins. The results obtained demonstrated that the inhibitory effect toward chlorophyll degradation was more pronounced for the monocotyledonous test-plant - barley.
