Crescimento de bagas de cultivares de uvas apirênicas tratadas com CPPU e GA3

Abstract: As cultivares de uvas apirênicas (Vitis vinifera L.), via de regra, possuem bagas de tamanhos reduzidos, necessitando de ajustes no manejo para a melhoria da qualidade dos cachos, sendo a aplicação de reguladores de crescimento um dos tratamentos mais eficazes. Objetivou-se com o presente trabalho avaliar os efeitos do forchlorfenuron (CPPU: 0 e 10 mgL-1) combinado ao ácido giberélico (GA3: 0, 25, 50, 75 e 100 mgL-1) durante o primeiro ciclo de produção das cultivares Centennial Seedless, Flame Seedless e Thom… Show more

“…In an experiment with different cyocel doses associated with benzyladenine, Ribeiro and Scarpare Filho (2003) found an increase of 28.22% in bud fertility of cv. Flame Seedless, highlighting the need for the joint application of the growth retardant and the benzyladenine.…”

“…In a different way, Melo and Ribeiro (2012), using the phytoregulator paclobutrazol (PBZ) associated with uracil, obtained significant values in the rate of sprouting of the buds of the "Thompson Seedless". Ribeiro and Scarpare Filho (2003) however, using chlorocholine chloride (CCC), obtained in the absence of the product rates of sprouting of the crops approximately 69%; and with applications of 50000 mg L -1 and 100000 mg L -1 of CCC, the rates exceeded 68.68% to 54.03% in "Thompson Seedless", and ranged from 45.29% to 16.24% in "Flame Seedless". These results suggest that the TrixE, with or without BA, same that applied in the dosage of 20 mg L -1 at 18, 38 and 58 DAPF did not lower the levels of gibberelin in the plants to the point of negatively affecting the bud sprouting rate.…”

“…Para tanto, Souza et al (2010) recomendam aplicações parceladas em 2 e 4 vezes de reguladores vegetais. Os mesmos autores encontraram valores médios de diâmetro de baga de 17 mm, aproximadamente, utilizando 10 mg L -1 de ácido giberélico (GA 3 ) + 5 mg L -1 de tidiazuron (TDZ), numa safra de 2006, na região de Jales, SP; entretanto, Ribeiro & Scarpare Filho (2003) observaram que as características de comprimento, diâmetro e peso de bagas dos cultivares 'Centennial Seedless', 'Flame Seedless' e 'Thompsons Seedless' são melhoradas com aplicações de forchlorfenuron (CPPU) e GA 3.…”
