TECCHIO, Marco Antonio et al. Plant growth regulators sprayings in 'Niagara Rosada' grape. Ciênc. agrotec. [online]. 2006, vol.30, n.6, pp. 1236-1240. ISSN 1413-7054.  http://dx.doi.org/10.1590/S1413-70542006000600030.

The experiment was made during august until dezember/2004 period, in grape orchard of 'Niagara Rosada' located at Pratânea region, São Paulo, Brazil. The research had as purpose to study the effects of plant growth regulator (Stimulate) on morphological and physical-chemical characteristics of 'Niagara Rosada' grape. The clusters were sprayed with plant growth regulator solution at 0, 5, 10, 15 e 20mg L^-1, 25 days after flowering. The experimental design was at randomized blocks with five replications and tree clusters per parcels. It was evaluated: the fresh weight of clusters and rachis, pedicel diameter, total soluble solids contents, titratable acid and pH. The plant growth regulator spraying increased the clusters length and pedicel diameter and decreased the soluble solids contents.
