The relationship between endogenous gibberellins and rosetting in Eustoma grandiflorum

Abstract

Treatments with gibberellin A1 (GA1), GA3 and GA20 promoted stem elongation in rosetted seedlings of Eustoma grandiflorum in the following order: GA1 = GA3 > GA20, whereas ent-kaurene (K), ent-kaurenoic acid (KA) and GA19 did not. GA1, GA3, GA19 and GA2
