In vitro rooting was significantly increased by adding indolebutyric
acid (IBA) to medium and rooting was improved by adding ١,٠ g/L activated
charcoal or ٠,١ g/L polyvinylpyrrolidone (PVP). Indoleacetic acid (IAA) (٠,٠ to
٤,٠ mg/L) was not effect
ive for rooting except when used with ٠,١ g/L PVP. A
٩٥٪ survival was achieved when plants were acclimatized ex vitro. Such
procedures could help significantly in clonally propagating bitter almond and
conserving its germplasm.
