Description
Summary:The article discusses the influence of caffeic acid (CA), its mix with chitosan (Chit + CA) and chitosan-based conjugate (Chit-CA) on growth and proline content of microclone potato plants ( Solanum tuberosum L.) in in vitro culture under optimal conditions and under prolonged osmotic stress caused by polyethylene glycol. Under optimal conditions Chit-CA and CA, acting as moderate strength stressors, accelerate the growth and development of potato microclones and increase the proline accumulation in the stems. Under osmotic stress CA and Chit-CA promote the resistance of potato microclones and maintain their active growth. And such effect persists during the reparation period. The mechanical mix Chit + CA causes inhibition of microclonal plants’ growth and development accompanied by a significant accumulation of proline which is aggravated under stress.
