In the current study, a simple cryopreservation method (desiccation) was applied to Corylus avellana L. callus. Accordingly, effects of abscisic acid (ABA) concentration, pretreatment duration on MS medium containing ABA + 10% sucrose, and storage length in liquid nitrogen (LN) callus survival rate were investigated. Calli’s assessed 8 weeks after exiting from LN. Callus significantly affected ...
