Morfoanatomia, tecnologia e fisiologia de frutos, sementes e plântulas de Apuleia molaris Spruce ex Benth. (Leguminosae caesalpinioideae).

Abstract

The yellowing (Apuleia moralis Spruce ex Benth.) Is a fast growing forest essence, recommended for recovery of degraded areas, belongs to the Fabaceae family, this species has problems botanical identification. Regarding the production of seedlings, there is insufficient information of the species for this purpose, and as currently the most ostensible monitoring forest degradation, the supervisory body are most active and so these are body determining the recovery of these areas, however technical-scientific information from Amazonian seeds are scarce. Thus, the aim of the present work and know the technological parameters, morphological and anatomical and physiological fruit, seeds and seedlings yellowing, contributing to scientific knowledge of Amazonian species, and assist the Ministry of Agriculture, Livestock and Supply in drafting regulations to forest species. We described the morphology of fruits, seeds and seedlings according to literature, to the anatomy followed by usual techniques for vegetable histology eophylls, metaphylls, hypocotyl and root seedling. For analysis we used the technological recommendations of rule analysis of seeds, and applied methods of breaking dormancy, temperature and substrate. For analysis saline were tested at concentrations of tetrazolium salt by exposure time, accelerated aging at 42 ° C and 45° C and relative humidity of 42 ° C for 0h, 24h, 48h, 72h and 96 h of exposure, the electrical conductivity at different times (1h, 2h, 3h, 4h, 5h, 6h, 7h, 12h and 24h), and acid addition giberélicos at concentrations of 500 mg to 1000 mg 16h and 32 hours. The seed of the species has characteristics common to family, having no striking anatomical differences between the hypocotyl and root, the methods of breaking dormancy is most suitable mechanical scarification at 25° C and substrate blotting paper. As for the seed physiological analysis is recommended concentration of 0.5% concentration of the tetrazolium salt for 6 hours, accelerated aging degradation favor the electrical conductivity of the membranes, facilitating the germination of species, as it has cutaneous numbness, does not recommend the use of hormone-based gibberellins. It is recommended testing time and of different concentrations of sulfuric acid and gibberellic acid for the species.
