RESUMO
O presente trabalho teve por objetivo estudar o enraizamento de estacas semilenhosas do porta-enxertode videira ‘IAC 572 – Jales’ em câmara de nebulização. Foram estudados 2 tipos de preparo de estacacom folha e sem folha, submetidas a tratamento com ácido indolbutírico (AIB) em 5 concentrações 0,500, 1000, 1500 e 2000 mg.L-1. O delineamento experimental utilizado foi o inteiramente casualizado emarranjo fatorial 2x5 (2 tipos de preparo de estaca e 5 concentrações de AIB), com 4 repetições e 8 estacaspor parcela. Foram avaliados aos 30 dias após a instalação do experimento as seguintes variáveis porcentagemde estacas enraizadas, porcentagem de estacas mortas, comprimento de raízes, massa de matéria fresca emassa de matéria seca das raízes. O tratamento com AIB influiu positivamente no enraizamento das estacascom folha, nas concentrações de 1500 e 2000 mg.L-1 o enraizamento foi de 96,8%. Nas estacas sem tratamentocom AIB o enraizamento foi de 68,7% e nas estacas sem folhas o tratamento com AIB não influiusignificativamente, sendo que a maior média de enraizamento foi de 21,8%.
ABSTRACT
The objective of this research was to study the rooting of semi hardwood cuttings of ‘IAC 575-Jales’ vine rootstock on mist chamber. It has been studied two sorts of cutting preparation with leaf and without leaf submitted to treatments with 5 concentrations, (0, 500, 1,000, 1,500 and 2,000 mg. L-1) of indolbutyric acid (IBA). A randomized design with 4 replications and 8 plants per plot was used as a statistical model (2-factor). After 30 days following variables were appraised the percentage of rooting, percentage of dead cuttings, length of roots and fresh and dry matter of roots. The treatment with IBA influenced positively in the rooting of the cuttings with leaf, in the concentrations of 1,500 and 2,000 mg.L-1 the rooting was of 96.8%. In the cuttings without treatment with IBA the rooting was of 68.7% and in the cuttings without leaves the treatment with IBA did not influenced significantly, and the higher average of rooting was 21.8%.
