DKW/Juglans medium

DKW/Juglans medium by Duchefa Biochemie is supplied for plant tissue culture and laboratory research.

Description and application

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.
