Emergência e crescimento inicial de plântulas de Eugenia jambolana Lam. Após remoção da polpa

Abstract

The fruit species of the genus Eugenia have great potential for environmental restoration, enabling not only the recovery of flora and fauna attraction. In the present research it was evaluated the effect of different treatments for removal of the pulp on the emergence and early growth of seedlings of Eugenia jambolana Lam. The treatments were rubbing with sand (T1), lime (T2), wood dust (T3), human tasting (T4), fermented for 24, 48, 72 and 96 hours (T5, T6, T7 and T8, respectively) and the control - whole fruit without any treatment (T9). After removing the pulp the seeds were washed in water and subsequently dried in a lab environment for 24 hours, and then sown in trays containing sand, using four replicates of 25 seeds per treatment. In assessing the effect of treatments it was determined the water content, percentage and index of germination speed, length and seedling dry weight. The water content of seed treatments reduced friction with lime and removing human, being higher in the control, but all treatments promoted high rates of emergency in relation to the control and the best results obtained in vigor removal treatments and human fermented for 24 and 96 hours.
