Emergência e desenvolvimento inicial de sementes de Dimorphandra mollis Benth. em campo

Abstract

Dimorphandra moliis Benth. (Laguminosae - Caesalpinioideae) is a tree species found in Cerrado, useful in the recovery of areas and as an ornamental plant. Rutin, estractedfrom the fruit, is a bioflavonoid used in the pharmaceutical industry which acts on the permeability and resistance of capillaries. This study aimed to determine the effects of soil type and fertilizers on the emergence and vigor of fava-d´anta sown directly in field. The experimental design adopted was randomized blocks in factorial scheme 4 × 2 (four types of fertilizer and two types of soil) with seven replications of five seeds each. We evaluated the following features: emergence, emergence first count, emergence speed index, seedling height and diameter. There was no significant interaction among factors, soil type and fertilizers. The best results for emergence and ESI (emergence rate index) are obtained when the seeds is sown in local soil.
