Appropriate micropropagation regimes were developed for four Pyrus species (P.
amygdaliformis Vill., P. betulaefolia Bunge, P. calleryana Dcne., and P. communis L.)
and Cydonia oblonga L. Shoot multiplication was optimal at 10 or 20μM N⁶⁻
benzyladenine (BA) and high light intensity (135μm⁻²s⁻1). Root formation of the
Pyrus species was stimulated...
