Objetivando estudar o efeito da aplicação do biorregulador Stimulate e X-Cyte na uniformidade de brotação das gemas do cultivar de uva sem sementes Superior Seedless, podadas em 22/05/2006, realizou-se experimento na Fazenda Koshiyama (Juazeiro/BA). O experimento foi conduzido em blocos ao acaso com quatro repetições, cada repetição com três plantas úteis onde se avaliou seis varas por planta. Quarenta e oito horas após a poda de produção, as varas foram tratadas via pulverização com: 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: X-Cyte (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, sendo a aplicação de Nitro Plus 9 na dosagem de 100 L ha-1 via fertirrigação. Os resultados obtidos neste trabalho com o uso de Stimulate e X-Cyte, visando a uniformidade de brotação, não demonstraram efeitos significativos sobre o número de brotos após a desbrota e a porcentagem de ramos desenvolvidos, em comparação ao produto comercialmente empregado (Dormex), indicando estes produtos como alternativas ao Dormex no cultivo da uva ‘Superior Seedless’, nas condições estudadas.
Aiming to study the affect of commercial biorregulators Stimulate (R) e X-Cyte (R) 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 (R) (5%); T2: Dormex (R) (5%) + Nitro Plus 9 (R); T3: Stimulate (R) (0,5%); T4: Stimulate (R) (0,5%) + Nitro Plus 9 (R); T5: Stimulate (R) (1,0%); T6: Stimulate (R) (1,0%) + Nitro Plus 9 (R); T7: X-Cyte (R) (0,25%); T8: X-Cyte (R) (0,25%) + Nitro Plus 9 (R); T9: X-Cyte (R) (0,5%); T10: X-Cyte (R) (0,5%) + Nitro Plus 9 (R); T11: X-Cyte (R) (0,25%) + Stimulate (R) (0,5%); T12: X-Cyte (R) (0,25%) + Stimulate (R) (0,5%) + Nitro Plus 9 (R), Nitro Plus 9 (R) used at a rate of 100 L ha(-1) via ferti-irrigation. Results show that Stimulate (R) and X-Cyte (R), when compared to the commercial product Dormex (R) commercially, did not show significant effects on the sprouts number after sproutings and proportion of grown stems; products that as an alternative the Dormex (R) in yield the grape 'Superior Seedless', at the studied conditions.
