Description
Summary:Physic nut is a useful species in oil production for energy purposes, however, its agricultural crop counts on little scientific knowledge. This work aimed to determine the water uptake curve in physic nut seeds, with the purpose to help future researches depending on this information. Two batches of seeds were used, represented by two sub-samples (intact seeds and dead seeds) of each batch. The water uptake curve was determined weighing samples at specified intervals of time. A fully randomized experimental delineation was applied, with two treatments and four repetitions of 10 seeds each. Data were submitted to Bartlett, Anova and Turkey tests; the regression equations were adjusted for the uptake curves. It was concluded that Jatropha curcas seeds follow the three-phases water uptake pattern, being phase I between 0 and 15h, phase II between 15h and 60h and phase three starting after 60h.
