Effect of Zeatin and 2iP on Shoot Proliferation of Three Highbush Blueberry Clones in Vitro

Abstract

Abstract N -(3-methyl-2-butenyl)-1 H -purin-6-amine (2iP) has been used to promote multiple shoot formation in previous tissue culture studies with ericaceous plants (1, 3-7). Fordham et al. (3), however, found that ( E )-2-methyl-4-(1 H -purin-6-ylamino)-2-buren-1-ol (zeatin) was the most effective cytokinin for stimulating shoot proliferation of cultured Exbury azalea ( Rhododendron sp.). This study was conducted to determine if highbush blueberry is similar to Exbury azalea in its response to zeatin.
