Cytokinins inhibit cell division
WebPlant growth regulators are extremely important natural hormones which control the growth and the physiological factors within the plant. They are naturally occurring as well as synthetic. PGRs like Auxins, ethylene, cytokinins and gibberellins are the growth inhibitors and growth retardants. WebApr 13, 2024 · Cytokinins (CKs) are produced by endophytic bacteria to enhance plant cell divisions and to tolerate environmental stresses including high-salt concentrations [128,129]. Indeed, the plant’s inoculation with microbes producing phytohormones including cytokinins helped to inhibit the adverse effects of salt and contributed to the amelioration ...
