Para tanto, o experimento foi dividido em três etapas: o primeiro, instaladoem viveiro telado na FCAUNESP, Botucatu - SP de agosto a outubro de 2013 com o cv. Niagara Rosada. O delineamento experimental foi inteiramente casualizado, com oito tratamentos e cinco repetições. O segundo experimento foiconduzido em ambiente protegido (casa de vegetação) na Embrapa Semiárido - Petrolina, PE de setembro a novembro de 2014 em esquema fatorial 2 x 8, dois cultivares (Isabel Precoce e Thompson Seedless) e oito tratamentos com reguladores vegetais e fungicidas, com cinco repetições e o terceiro, conduzido em ambiente protegido (viveiro telado) em área comercial da RKF Mudas - Juazeiro, BA de dezembro/2014 a fevereiro/2015 em esquema fatorial 3 x 8, com três cultivares,Niagara Rosada, Isabel Precoce e Thompson Seedless, e oito tratamentos. Em todos os experimentos os tratamentos utilizados foram: T1- Testemunha (água); T2- Putrescina (Put, 2 mM); T3- Citocinina (CK, 6-BA 20 mg L-1); T4- Piraclostrobina (Pira, 200 g 100 L-1); T5- Put + CK; T6- Put + Pira; T7- Pira + CK; T8- CKvia foliar (20 mg L-1) + via solo (40 mg L-1), com aplicações realizadas uma vez p...

Therefore, the experiment was divided in three stages, the first being conducted in a shaded nursery at FCA-UNESP, Botucatu (SP), from August to October 2013 with the cv. Niagara Rosada. The experimental design was completely randomized, with eight treatments and five repetitions. The second experiment was conducted in protected environment (greenhouse) at Embrapa Semiárido, Petrolina (PE), from September to November 2014, using factorial design (2 x 8), two cultivars (Isabel Precoce and Thompson Seedless) and eight treatments with five repetitions; while the third one, also in protected environment (shaded nursery), was conducted in the commercial nursery of RKF Mudas, Juazeiro (BA), from December 2014 to February 2015, using factorial design (3 x 8), three cultivars (Niagara Rosada, Isabel Precoce and Thompson Seedless) and eight treatments. The treatments for all experiments consisted of: T1- Control (water); T2- Putrescine (Put, 2 mM); T3- Cytokinin (CK, 6-BA 20 mg L-1 ); T4- Pyraclostrobin (Pira, 200 g 100 L-1 ); T5- Put + CK; T6- Put + Pira; T7- Pira + CK; T8- CK via leaves (20 mg L-1 ) + applied to soil (40 mg L-1 ), with applications carried out once a week, at a total of three applications. In order to assess the effectiveness of the treatments, morphological and physiological parameters of the cultivars were evaluated as follows ... / Doutor
