Only a single study exists for B. tomentosa
(Naz et al. 2012). Nodal explants from in vitro seedlings
could form 12 shoots per explant after 6 weeks
on MS medium containing 50 mg·dm-3
adenine
sulphate (AS), 5.0 µM BA and 0.5 µM NAA. Roots
were induced in the presence of 5.0 µM chlorogenic
acid and 2.5 µM IBA from 70% of shoots within 4
weeks. MS was more effective than WPM as a basal
medium. Polyvinylpyrrolidone and ascorbic acid
were able to reduce polyphenolics in vitro.
