Conservazione della biodiversità di susino attraverso crescita rallentata in vitro

Abstract

In vitro techniques have been proved to be also helpful in the conservation of the plant biodiversity. With this approach, some Sicilian cultivars of European plum (Prunus domestica L.) have been investigated for the application of in vitro slow growth storage at 4°C and in the dark. Established shoot cultures of two cv (Ariddo di Core and Sanacore) have been cultured in MS basal medium containing different concentrations of sucrose (20 and 30 g l-1) and PGRs (BAP and IBA). The experiment is in progress and the reported data are relative to the first 90 days of in vitro preservation.
