Resumo: The greatest difficulty in the process of propagation through orchid tissue culture lies on the acclimatization phase. The objective of this study was to evaluate the efficiency of different vegetal substrates under two irrigation systems, during the acclimatization phase of the Cattleya chocolate drop x (Cattleya guttatax Laelia tenebrosa). Orchid seedlings in vitro cultivated were transplanted to the following substrates (treatments): S1: coconut powder; S2: coconut fiber; S3: defibered xaxim (tree fern fiber) and S4: sphagnum. Next, they were acclimatized in two irrigation systems: IM: hand-operated and II: intermittent. The following variables were assessed ninety days after transplanting: number of roots, aerial part height, fresh weight, number of plants with shoots, pH substrate and seedling survival rate. The coconut powder substrate and intermittent irrigation system were the most indicated for the acclimatization of the Cattleya chocolate drop x (C. guttata x L. tenebrosa) orchid.

O presente trabalho teve como objetivo avaliar a eficiência de diferentes substratos de origem vegetal, sob dois sistemas de irrigação, durante a fase de aclimatação da orquídea Cattleya chocolate drop x (C. guttata Lindl. x L. tenebrosa Lindl.). Plântulas provindas do cultivo in vitro foram transplantadas para os substratos que compuseram os seguintes tratamentos: S1: pó de coco; S2: fibra de coco; S3: xaxim desfibrado e S4: esfagno. Em seguida, foram aclimatadas sob dois sistemas de irrigação: IM: manual e II: intermitente. Aos noventa dias após o transplantio foram avaliadas as variáveis número de raízes, altura da parte aérea, peso de matéria fresca da planta, número de plantas com broto, pH dos substratos e proporção de sobrevivência das plântulas. O substrato pó de coco e o sistema de irrigação intermitente (10 minutos por 5 segundos) foram os mais indicados para a aclimatização da orquídea Cattleya chocolate drop x (C. guttata x L. tenebrosa).Universidade Estadual de Maringá2008-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/213410.4025/actasciagron.v27i1.2134Acta Scientiarum.
