Produção de mudas de Myracrodruon urundeuva Fr. All. fase II: simulação de campo

Abstract

This study aimed to evaluate the post-planting seedlings performance Myracrodum urundeuva Fr. All. Produced in different ages and volume containers. The experiment was conducted at the Federal University of Recôncavo of Bahia in Cruz das Almas campus - Ba. The seedlings were grown in the stands with suspended plastic tubes of sizes 55, 180 and 280 cm3, in 50% shading the greenhouse. The experimental design was completely randomized with six replications (repetition per plant) and three treatments being conducted two experiments related to seedling ages 60 and 75 days. There was no significant interaction between the container volume and the ages of seedlings. For the production of M. urundeuva seedlings indicates the use of volume tubes 180 and 280 cm3. For the variables initial height, final height, joint analysis indicated no significant interaction between the container volume and the ages of seedlings. And the container volume of 280 cm3, regardless of seedling production cycle, resulting in greater height, larger initial diameter and greater length taproot compared to other sizes of tubes. As for the seedling production cycle, regardless of the container volume, only the initial height of the seedlings responded ages, being higher after 75 days. Thus, after 60 days of field simulation, as the final height did not differ between the two production cycles assessed. Comparing the seedling production cycles 60 and 75 days for M. urundeuva, it is concluded that the most suitable for this species is a cycle of 60 days.
