Resumo
Embora a quase totalidade da produção nacional de caqui (Diospyros kaki L.) seja destinada ao mercado interno, o Brasil vem se consolidando nos últimos anos como país exportador dessa fruta para países dos continentes americano e europeu. Por essa razão, o cultivo dessa fruteira vem se constituindo numa importante atividade agrícola para pequenos produtores no Brasil. A obtenção de mudas de boa qualidade para a implantação de pomares constitui-se em sério problema para os fruticultores que pretendem cultivar o caquizeiro, métodos alternativos para a produção de mudas, amenizariam essa dificuldade. Em função disso o presente trabalho objetivou avaliar a porcentagem de pegamento da enxertia de mesa em estacas lenhosas oriundas das brotações do porta-enxerto, a capacidade de enraizamento de estacas lenhosas e herbáceas de caquizeiro oriundas de brotações da copa e do porta-enxerto, ambos da cultivar Rama-Forte, determinar a concentração mais adequada de indolbutírico (AIB) e ainda avaliar a fenologia de dez variedades de caquizeiro (Pomelo, Rubi, Fuyuhana, Rama Forte, Taubaté, Giombo, Suruga, Toote, Fuyu, e Jiro), selecionar aquelas que apresentem melhores características agronômicas e que sejam adaptadas às regiões de clima tropical. O trabalho foi conduzido no período de 16 de março de 2006 a 29 de maio de 2007 na área experimental da Fazenda de Ensino, Pesquisa e Extensão da Universidade Estadual Paulista - Campus de Ilha Solteira, localizada no município de Selvíria - MS. Para a enxertia de mesa foram utilizadas 120 estacas lenhosas oriundas do porta-enxerto onde foi realizada a enxertia por garfagem tipo fenda cheia e divididos em quatro tratamentos com três repetições de 10 estacas, sendo três concentrações de AIB (1500, 2500 e 3500 mgL-1) e a testemunha (sem aplicação de AIB), imergindo-se 5cm da base por cinco minutos na solução...
Although almost the totality of the national production of Kaki (Diospyros kaki L.) either destined to the domestic market, Brazil comes if consolidating in the last years as exporting country of this fruit for countries of the American and European continent. Therefore, the culture of this fruit comes if constituting in an important agricultural activity for small producers in Brazil. The attainment of props of good quality for the implantation of orchards consists in serious problem for the producers of fruits that they intend to cultivate the Japanese Persimmon Tree. The present work objectified to evaluate the percentage of the bench graft in deriving rootstocks props, the shoots of the rootstocks, the capacity of grafting of deriving rootstocks and herbaceous props of Japanese Persimmon Tree of shoots of the pantry and the rootstocks, both of cultivating Rama Forte, to determinate the indolbutiric concentration most adequate (IBA) and still the phenology of ten varieties of Japanese Persimmon Tree (Pomelo, Ruby, Fuyuhana, Rama Forte, Taubaté, Giombo, Suruga, Toote, Fuyu, and Jiro), to select those that present good characteristics and that the regions of tropical climate are adapted. The work was lead of day 16 of March of 2006 until day 29 of May of 2007 in the experimental area of the Farm of Education, Research and Extension of the São Paulo State University - Campus of Ilha Solteira, located in the city of Selvíria-MS. In the bench graft 120 deriving rootstocks props of the rootstocks had been used where type full crack and divided in four treatments with three repetitions of 10 props was carried through by full crack, being three concentrations of IBA (1500, 2500 and 3500 mgL-1) and the witness (without IBA application), immerging 5cm of the base per five minutes into the solution...(Complete abstract click electronic access below)
