Produção de mudas de Psidium cauliflorum Landrum & Sobral fase I: viveiro

Abstract

The anthropic impacts on the Atlantic Forest Biome have been intensifying in the last decades, that today it is a priority to conserve the few remaining areas and to restore degraded areas. The production of seedlings in quantity and quality is an important step in this process, since it is one of the factors of great influence in the establishment of forest species, to obtain a good productivity and quality of the stands or in projects of recovery of degraded areas. The objective of this work was to develop a protocol for the production of seedlings for Psidium cauliflorum, in order to obtain information to guide the producer in the production of quality seedlings and to achieve the potential of the species, aiming at obtaining seedlings of quality in production systems that allow, increase productivity, reduce costs and preserve the environment. Evaluating the ideal seeding depth, percentage of germination, rate of emergence velocity, stem volume and to keep in the greenhouse. The results showed great viability of the production of good quality seedlings. The seeds of P. cauliflorum should be sown at 4 cm depth, to achieve greater emergence and vigor of the seedlings, tubes of 55 cm³ are not indicated for seedling production and based on the results obtained, it was not possible to define the ideal time to keep seedling in the greenhouse during the evaluated period.
