Analysis of endogenous gibberellins and abscisic acid in vegetative shoots of normal and weeping japanese cherry (prunus spachiana)

Abstract

Gibberellin A1 (GA1), GA15, GA19, GA20, GA29, GA44, and abscisic acid (ABA) were identified from vegetative shoots of Japanese cherry (Prunus spachiana Kitamura f. ascendens Kitamura, Edo-higan) by full-scan GC-MS. GA4, GA9, GA34, and GA53 were also tentatively identified. The endogenous levels of these gibberellins and of ABA were higher in the weeping cherry (P. spachiana Kitamura f. spachiana cv. Plenorosea, Yaebeni-shidare) than in the normal cultivar (Edo-higan). © 1996, Taylor & Francis Group, LLC. All rights reserved.
