Effects of Gibberellin on Redox Enzyme Activity and Leaf Chlorophyll Pigments in Maize Leaf Cells

Abstract

In the article, the effect of gibberellin on the activity of oxidation-reduction enzymes and leaf chlorophyll pigments in the cells of the leaf of the corn plant was studied on the basis of field and laboratory experiments. It was found that when gibberellin suspension is sprayed on plants, the amount of chlorophyll "a" increases, especially during the periods of sultan release. The amount of chlorophyll "b" increased during the ripening phase. The ratio of chlorophyll "a" and "b" had the highest value in the period of growth, and the lowest value in the period of ripening. Carotenoids increased during sultana release and decreased during ripening. Photochemical reduction in leaf chloroplasts under the influence of gibberellin suspension increased by 20-30% compared to the control in all periods of vegetation. The studied Uzbekistan 601 ESV variety was distinguished by its reactivity.
