| Research Abstract |
Associations between petal growth patterns and the formation of three-dimensional corolla shapes were investigated in Eustoma grandiflorum. The cultivars showing outward curvature in the distal regions of petals exhibited a rapid distal widening during the later stages of flower opening, whereas the cup-shaped cultivars exhibited a rapid widening in the basal to middle regions of petals during earlier stages of flower development. In a funnel-shaped cultivar showing no apparent curvature, no regional differences in petal expansion were found. The data suggested that non-uniform cell expansion within a petal results in petal distortion, and this plays a central role in corolla curvature formation.
