Abstract

One of the problems encountered in the formation of stands aimed at forest restoration is the quality of the seedlings. The objective of this study was to evaluate the different volumes of tubes for the seedling production of Ceiba speciosa, using biosolids as a substrate. The experiment consisted of the seedlings production stage and evaluation of the performance in the field. The treatments were the tubes of 55, 110, 180 and 280 cmГ. Both phases of this experiment were installed in a completely randomized design, with the stage of seedling production composed by four repetitions of 12 plants, and field stage composed by 20 seedlings from each treatment, with height and diameter closer to the average for the last assessment carried out in the nursery. Using biosolids as the main component of the substrate for the production of Ceiba speciosa seedlings, and for the site conditions where the forest stand was implanted, it is recommended to use the 110/cm3 tube, because in this tube occurred growth similar to plants in the tubes of larger volumes, resulting in lower volume of substrate, smaller area occupied in the seed-plot and greater ease of transport and handling.

Resumo

Um dos problemas encontrados na formaчуo de povoamentos visando р restauraчуo florestal щ a qualidade das mudas. O objetivo deste trabalho foi avaliar diferentes volumes de tubetes para a produчуo de mudas de Ceiba speciosa, utilizando o biossѓlido como substrato. O experimento constou da fase de produчуo das mudas e da avaliaчуo do desempenho dessas no campo. Os tratamentos utilizados foram os tubetes de 55, 110, 180 e 280 cmГ. Ambas as fases do experimento foram instaladas em delineamento inteiramente casualizado, sendo a fase de viveiro composta por quatro repetiчѕes de 12 plantas, e a fase de campo composta por 20 mudas de cada tratamento, com altura e diтmetro mais prѓximos da mщdia da њltima avaliaчуo realizada no viveiro. Utilizando-se o biossѓlido como principal componente do substrato para a produчуo das mudas de Ceiba speciosa, e para as condiчѕes de sэtio em que foi implantado o povoamento florestal, recomenda-se o uso do tubete de 110/cm3, pois neste ocorreu crescimento similar ao das plantas nos tubetes de maior volume, resultando em menor volume de substrato, menor сrea ocupada no viveiro e maior facilidade de transporte e manejo.
