– BAP9THP is a synthetic cytokinin derivative and a growth regulator. BAP9THP promotes chlorophyll retention (and senescence delay) in plant tissues exceptionally strongly, and growth of tobacco callus almost as strongly as 6-Benzylaminopurine (BAP). BAP9THP induces adventitious shoot formation ignificantly more strongly than N6-isopentenyladenine or Kinetin.
