Curva de embebição de água para sementes de Magonia pubescens A. ST.- HIL

Abstract

The objective of this work was to determine the soaking curve for seeds of Magonia pubescens species in different substrates with whole winged and cut winged integument. The experiment was conducted at the Seed Analysis Laboratory of the Federal University of Recôncavo da Bahia (UFRB), on the Cruz das Almas campus. The experimental design was completely randomized (DIC), with 4 treatments and 8 replications of 10 seeds each. distilled (T2), with integument in moist germestest paper (T3) and seeds with integument cut in moist germitest paper (T4). To determine the soaking curve the seeds of each treatment were periodically weighed with the aid of a precision analytical balance. Initially weighing at two-hour intervals for a period of 24 hours and after this period the evaluations took place every 12 hours, ending the weighing when at least 50% of the seeds of each repetition had emitted the radicle. Data were submitted to analysis of variance by RStudio software. The M. pubescens seed imbibition curve for all treatments showed a constant and significant increase around 40 hours from the beginning of water absorption (Phase I). Germitest paper was the method that presented the best conditions for germination, being the gerbox box not suitable for experiments like this for this species.
