EFFECT OF KINETIN-GRAPHENE OXIDE NANOENSEMBLE ON THE DEVELOPMENT AND ANTIOXIDANT SYSTEM OF COTTON
Abstrack

Abstract. The application of nanotechnology in agriculture is gaining increasing significance. The
use of graphene oxide (GO)-based nanoensembles as stabilizers of functional groups or plant growth
inducers, such as phytohormones, represents a promising direction for further research. This study
aimed to conduct a comparative analysis and examine the effects of a GO-based nanoensemble with
the phytohormone kinetin on the morphophysiological and biochemical parameters of Gossypium
hirsutum L. Agdash-3 cultivar seedlings. Morphophysiological analysis revealed that treatment
with kinetin + GO stimulated seed germination and increased stem length compared to the control
and free kinetin treatment. Biochemical studies demonstrated an increase in polyphenol oxidase
activity, the concentration of photosynthetic pigments (chlorophyll a and carotenoids), as well as
proline content in leaf tissues upon nanoensemble treatment. In contrast, root length, catalase and
guaiacol peroxidase activity, along with chlorophyll b and proline concentrations in roots, remained
at levels comparable to those observed with kinetin alone, suggesting no additional effect of GO on
these parameters.
The obtained results indicate a synergistic effect of GO in combination with kinetin on specific
morphophysiological and biochemical characteristics of cotton seedlings, highlighting potential
avenues for further research.
