[Effects of plant growth regulators ambiol and phonk: biolphysical aspects].
The antioxidative activity of two plant growth promoters, ambiol and phonk, in a model system of photo-induced glycyltriptophane oxidation was measured. It was shown that ambiol has a significant antioxidative activity, whereas phonk is a weak antioxidant. The effects of these compounds on DNA conformation were studied in vitro and in vivo (on wheat seed shoots). In vitro ambiol had a stronger effect as compared with phonk, whereas in vivo the latter produced a more essential effect than ambiol. The assumption was done that both compounds affect indirectly the genome expression activity. Possible mechanisms of biological activity of each compound are discussed.
