Resumo: | The kiwi, as a dioecious plant, produces male and female flowers in different individuals which makes the pollination difficult - a necessary condition for good yields. A trial was carried out in an orchard in the region of Guarapuava, state of Paraná, Brazil, aiming at studying the effect of CPPU on the fruit development of kiwi cv. Bruno. The treatment consisted of spraying the flowers when 50% of them were opened with an aqueous solution of CPPU at 0, 2.5, 5.0, 7.5, 10.0 and 12.5 mg L–1, and also a treatment with hand-pollination was done. The treatment with CPPU and hand-pollination increased the fruit set, without changing the size and the weight of the fruits. The treatment with CPPU at 5 mg L–1 increased the percentage of fruit set from 54.6% on the control to 87.5%. Nevertheless, the treatment with CPPU at 12.5 mg L–1 decreased the total soluble solids content of the mosto. |

Nesse contexto, um experimento foi conduzido em pomar na região de Guarapuava, Estado do Paraná, com o objetivo de estudar o efeito do CPPU na frutificação do kiwi cv. Bruno. Os tratamentos consistiram de pulverizações dirigidas às flores, quando 50% destas se encontravam abertas, de soluções aquosas de CPPU a 0; 2,5; 5,0; 7,5; 10,0 e 12,5 mg L–1 , além de um tratamento em que se realizou polinização manual. Os tratamentos com CPPU e com polinização manual aumentaram significativamente a porcentagem de pegamento dos frutos sem interferir em seu tamanho e peso. O tratamento com CPPU a 5,0 mg L–1 aumentou a porcentagem de pegamento dos frutos de 54,6% na testemunha para 87,5%. No entanto, o tratamento com CPPU a 12,5 mg L–1 reduziu o teor de sólidos solúveis totais do mosto.Universidade Estadual de Maringá2008-04-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/190810.4025/actasciagron.v27i2.1908Acta Scientiarum.
