PRODUCTION OF SEEDLINGS OF Psidium cauliflorum Landrum & Sobral
ABSTRACT In the absence of knowledge about the procedures for production of seedlings of particular tree species, determining the nursery production period and quality standards are normally priority aspects for studies. As there is no information on the propagation of P. cauliflorum in the literature, the objective of this study was to determine the length of stay in the nursery, the size of the container and the quality standards for the production of seedlings of this species, based on the performance in the nursery and in the field. The work was carried out in two stages. In the first, seedling growth was analyzed in the nursery and in the second stage their performance was analyzed in the field. We tested three container sizes: 55 cm3 (12.5 cm-length x 2.9 cm-internal diameter), 180 cm3 (13.5 cm x 5.2 cm) and 280 cm3 (19.0 cm x 5.2 cm) and different periods of seedling production in tubes (15, 30, 45, 60, 75, 90, 105 and 120 days). It is recommended that P. cauliflorum seedlings be grown in containers of 180 cm3 (13.5 cm x 5.2 cm) and remain in these containers for at least 120 days. The experiment to assess post-planting performance was crucial to obtain conclusive results for the production of P. cauliflorum seedlings.
