Resumo: | Berberis laurina Billb. (Berberidaceae) is a native shrub from Floresta Ombrófila Mista ecological formation, very ornamental and useful specie for recovery of degraded areas. With medical applications, its fruit is edible and its roots are used as dye. This paper aims to analyze lhe induction of lhe rooting of Berberis laurina stem cuttings employing indolebutyric acid (IBA) in O, 1000 and 2000 mgL-1 concentrations, using the vermiculite as growing medium. In october 2003, stem cuttings were collected from eight stock plants, located in Fazenda Rio Grande - PR. Semi-hardwood cuttings were preppared with 8.0 cm long by 0.35 cm of diameter shape, containing three leaves on the top, cut in a half, the base was cut in diagonal and the top was cut straight, receiving a treatment with sodium hipochlorite (0.5%) for 10 minutes. The experiment was being conducted in a greenhouse. After 90 days an analysis was taken from the rooting rate, rate of the number of roots formed per cuttings, length of the three biggest roots formed per cuttings, rate of the initial leaves which have survived since the cutting’s manufacture per cutting, rate of sprout presence per cutting, rate of not rooted living cuttings and rate of dead cuttings. The analyzed variables did not show a significative difference using 5% of probability, except for the rate of not rooted living cuttings which had differed statistically; however, the rooting rate was above the ones found in studies made with another species of Berberis (20.0 - 30.0 %). IBA did not improve the rooting of B. laurina. |

Possui aplicação medicinal, seu fruto é comestível e suas raízes são utilizadas como corantes. Este trabalho teve como objetivo analisar a indução do enraizamento de estacas caulinares de B. Iaurina pela aplicação de ácido indol butírico (AIB), nas concentrações O, 1000 e 2000 mgL-1, utilizando o substrato vermiculita de granulometria média. Em outubro de 2003, foram coletadas estacas caulinares semilenhosas, de oito plantas matrizes com aproximadamente 10 anos de idade, localizadas no município de Fazenda Rio Grande - PR, confeccionadas com aproximadamente 8,0 cm de comprimento e 0,35 cm de diâmetro, com 3 folhas na porção apical cortadas pela metade, base cortada em bisel e ápice em corte reto, recebendo tratamento fitossanitário com hipoclorito de sódio a 0,5% por 1O minutos e transferidas para casa-devegetação climatizada. Após 90 dias, foram avaliadas as porcentagens de estacas enraizadas, número de raízes formadas/estaca, comprimento das três maiores raízes formadas/estaca, porcentagens de folhas iniciais mantidas na confecção das mesmas/estaca, de brotações/estaca, de estacas vivas não enraizadas e de estacas mortas. As variáveis analisadas não se mostraram diferentes significativamente ao nível de 5% de probabilidade, com exceção da variável porcentagem de estacas vivas não enraizadas; entretanto, as porcentagens de estacas enraizadas obtidas foram superiores às encontradas em estudos com outras espécies do gênero Berberis (20,0 a 30,0%). No entanto, a aplicação de AIB não promoveu o aumento do enraizamento da espécie.
