SOILLESS PROPAGATION METHOD AND DEVICE

摘要

A method for obtaining plant reproductive organs, comprising a first step wherein cuttings are propagated in vitro from meristems, a second step wherein said cuttings are propagated and lengthened to give seedlings, and a third step wherein said seedlings are grown into tubers. The second and third steps are carried out under aero-hydroponic conditions with a nutrient solution that is substantially identical to solutions suitable for use under in vitro culture conditions. Said method is particularly suitable for preparing potato minitubers. A device for carrying out the method is also disclosed.
