MNOŽENÍ KOMPAKTNĚ ROSTOUCÍ SLIVONĚ ‘DWARF’ V IN VITRO KULTUŘE [ PROPAGATION OF THE COMPACTLY GROWING PLUM ‘DWARF’ IN CONDITIONS OF IN VITRO CULTURE]

Abstract

In vitro propagation techniques particularly apply for genotypes, where classic approach fails to succeed or if it is less efficient. One of these cases is compactly growing plum cultivar ‘Dwarf’, which considerably complicates the nursery propagation due to its shortened internodes. For in vitro micropropagation of this plum, we tested the Murashige and Skoog (1962) growth media with cytokinin added: 6-benzylaminopurine, thidiazurone or 2- isopentenyladenine. The highest multiplication coefficient (2.56) was achieved at 4 mg/L of 6-benzylaminopurine.
