Abstract
Aiming to study the affect of commercial biorregulators Stimulate® e X-Cyte® over sprouting uniformity of Superior Seedless grape cultivar, pruned in May 22, 2006, a field trial was carried out at at Koshiyama farm, in Juazeiro municipality (Bahia State/Northeastern Brazil). The trial was carried out in randomized blocks with four replications and three useful plants per plot, six stakes per plant were evaluated. Forty-eight hours after yield prun, the stakes were sprayed with T1: Dormex® (5%); T2: Dormex® (5%) + Nitro Plus 9®; T3: Stimulate® (0,5%); T4: Stimulate® (0,5%) + Nitro Plus 9®; T5: Stimulate® (1,0%); T6: Stimulate® (1,0%) + Nitro Plus 9®; T7: X-Cyte® (0,25%); T8: XCyte ® (0,25%) + Nitro Plus 9®; T9: X-Cyte® (0,5%); T10: X-Cyte® (0,5%) + Nitro Plus 9®; T11: X-Cyte® (0,25%) + Stimulate® (0,5%); T12: X-Cyte® (0,25%) + Stimulate® (0,5%) + Nitro Plus 9®, Nitro Plus 9® used at a rate of 100 L ha-1 via ferti-irrigation. Results show that Stimulate® and X-Cyte®, when compared to the commercial product Dormex® commercially, did not show significant effects on the sprouts number after sproutings and proportion of grown stems; products that as an alternative the Dormex® in yield the grape 'Superior Seedless', at the studied conditions.
