Potential physiological seed Clitoria fairchildiana howard in time function and drying temperature
Keywords:Sombreiro. Forest species. Desiccation. Water content.
The species Clitoria fairchildiana Howard, native to the Amazon region, by a rustic species and be of rapid growth, has been useful in heterogeneous reforestation for the revegetation and reclamation of degraded areas, used in the planting of streets, public squares, roads and parking lots, due to its wide, leafy canopy and its rapid growth. The work was developed in the Laboratory of Analyses of Seeds of Centro de Ciências Agrárias of Universidade Federal da Paraíba. Thus, this study aimed to evaluate the physiological potential of C. fairchildiana seeds submitted to different drying times. The experimental design completely randomized, with treatments distributed in a factorial 4 x 5 (temperatures and periods of drying). It was evaluated to determine the water content after the drying processing for each period (0, 6, 12, 18 and 24 hours). For the evaluation of the effect of temperatures (35, 40, 45 and 50°C) were performed the following tests: water content, germination, germination speed index (IVG), as well as length and dry mass of roots and aerial portion of seedlings. Drying of seeds of C. fairchildiana is recommended at the temperature of 35°C, within hours drying 6h without compromising the physiological quality of seeds.
