Armazenamento de sementes de Senegalia baihenses (Benth.) Seigler. & Ebinger

Abstract

The objective was to evaluate the influence of the environment collecting seeds Senegalia bahienses on the storage time in these laboratory conditions. Storing seeds of native species enables the use of these species in different times and places so they keep their physiological quality, which is an important for the maintenance of germplasm banks and procedures reclamation factor. Germination test was conducted in Biochemical Oxygen Demand germination type (BOD) to assess the time that the seeds could be stored Senegalia bahienses remaining viable using continuous light and temperature of 30 ° C and leaves germitest paper. The experimental design was completely randomized (CRD) in factorial 4 x 3 (four storage periods (0, 90, 120 and 150 days) and two environmental samples (edge and pasture), with three replications of 25 seeds each. the water content of the seeds was quantified using two replicates of 4.5 - 5.0 g of seeds per repetition for each period of storage time, subjected to 105 ° C for 24h each test lasted for seven days the counts were performed in the second and seventh days, germinated when considering who issued the primary root and were apparently healthy and normal variables analyzed were: IVG, germination percentage, dry weight, root length, shoot and total root reason shoot and moisture. Data were submitted to analysis of variance (ANOVA) and factor regression analysis period. Conclusion is the end of this work that Senegalia bahiensis had its period of viability considered short (90 days), occurring loss physiological seed quality Senegalia bahiensis over the period of storage.
