ENRAIZAMENTO DE ESTACAS LENHOSAS DE CULTIVARES DE KIWIZEIRO

The present work was carried out with intention to verify the rooting of kiwi cultivars woody cuttings. Woody cuttings of Hayward, Monty, Abbott, Allison, Tomuri and Bruno cultivars were collected in the end of July, standardized with 20 cm in length and basal diameter of 0.8 cm, we performed a straight cut at the apex of the cutting and another in the base. After incisions were made at the base of the cutting, they were immerged for 10 seconds in IBA (indol butyric acid) at 8000 mg dm-3. The cuttings were buried in sand, in a greenhouse and after 90 days it was concluded that the cutting of kiwi cultivars differ as the budding and rooting and that the cuttings of Allison cultivar, had presented better results of the rooting and sprouting percentage.O presente trabalho foi realizado com o intuito de verificar o potencial de enraizamento de estacas de diferentes cultivares de kiwizeiro. Estacas lenhosas das cultivares Hayward, Monty, Abbott, Allison, Tomuri e Bruno foram coletadas no final de julho, padronizadas em 20 cm de comprimento e diâmetro basal de 0,8 cm com um corte transversal da estaca no seu ápice e outro em bisel na base. Após preparadas foram realizadas incisões na base das estacas e sua imersão por 10 s em AIB (ácido indolbutírico) a 8000 mg dm-3. As estacas foram inseridas em leito de areia umedecido sob telado e decorridos 90 dias concluiu-se que as estacas de kiwizeiro diferem quanto à brotação e enraizamento e as estacas da cultivar Allison são as que possuem a maior porcentagem de enraizamento e brotação
