Kinetin induces chromosomal abnormalities in African Blue Lily (Agapanthus praecox ssp. minimus) grown in In Vitro

Kinetin has been reported to exert inhibitory effect when used in tissue culture and in some cases reverse the action of auxin and cause growth inhibition and retardation of root formations. Kinetin also acts as ‘mitotic poison’, mimicking the effect of pesticides and toxic chemicals and interferes...
