Evaluation of Seven Media for Micropropagation of Highbush Blueberry

Abstract

Shoot growth of highbush blueberry ( Vaccinium corymbosum L. cv. Bluecrop) in vitro was compared on various modifications of Murashige and Skoog (MS) medium containing Linsmaier and Skoog (LS) vitamins, Zimmerman’s Z-2 and Z-3 media, a modified Knop’s medium, and McCown and Lloyd’s woody plant medium (WPM). The WPM was found to produce best growth and highest number of shoots of 10 mm or longer. Shoots from Zimmerman’s half-strength medium (Z-3) yielded the highest percentage of rooting in sifted sphagnum peat.
