Abstract

Aim. Research of the adaptive morphogenesis in Kalanchoe Daigremontiana uder the action of Izatison components, the composition of the solvents DMSO and PEG 400 (D+P). Methods. The leaves of Kalanchoe plants of the same age and origin, grown in laboratory condition by the method of soil culture, were used for the investigation. For D+P, the same dilutions values as in previous study for Izatisone were chosen. Results. The possible impact of D+P as stressors, which are inherent in causing a significant range of variability regarding the initiation, development and growth of the plantlets in Kalanchoe Daigremontiana, was revealed. Depending of the D+P concentration and of the individual susceptibility of the kalanchoe plants, D+P showed the ability to both stimulate and inhibit the development and growth of the plantlets, but in most cases such effects were not statistically significant. Conclusions. Hence, the stimulatory effect of Izatison on the appearance of plantlets in Kalanchoe Daigremontiana and their morphogenesis and growth, revealed by us earlier, is due, apparently, to N-methyl isatin ß-thiosemicarbazone, a derivative of isatin, which is a known phytohormone.
