Description
DKW medium has been defined for in vitro propagation of Paradox Walnut Rootstock (Juglans hindsii x J. regia) via nodal explants. The explants were placed on medium without growth-regulators for one week and subsequentely on medium containing 6-BAP and IBA. Opti-mum shoot development was supported under 4.5 µM 6-BAP and 5 nM IBA. The basal ends of the tissue culture derived shoots were dipped in 5 mM IBA solution and subsequen-tly rooted within 10 to 14 days in the greenhouse.
