“…The absence of an effect of ABA (and of other medium components) might also be the result of a late induction of dormancy during culture. For seeds it is known that dormancy is induced during the second phase of seed development [9]. If the same holds for ih-vitro generated lily bulblets, ABA possible had already been taken up and catabolized before the bulblets had entered the dormancy-induction phase.…”

“…A mucuna-preta (Mucuna aterrima (Pipper et Tracy) Holland) é uma leguminosa anual ou bianual, de crescimento indeterminado, porte baixo, hábito rasteiro e com ramos trepadores vigorosos e bem desenvolvidos (Trani et al, 1989;Wutke, 1993). É cultivada para adubação verde, mas pode ser utilizada na alimentação animal como forrageira, em pastejo direto e na forma de silagem ou feno; seus grãos triturados constituem suplemento protéico aos animais (Calegari, 1995).…”

RESUMO -A mucuna-preta é uma leguminosa empregada para adubação verde e como forrageira, cujas sementes apresentam dormência causada pela impermeabilidade do tegumento à água. O objetivo deste trabalho foi estudar a intensidade de dormência das sementes de mucuna-preta em diferentes estádios de maturação quando submetidas à secagem no interior das vagens. Rácemos foram colhidos, semanalmente, a partir de 35 dias do início de florescimento (35 DAF) até o estádio de vagens secas (98 DAF). As sementes de cada colheita foram secadas no interior das vagens, em condições ambientais não controladas de laboratório; quando secas foram extraídas, avaliadas quando a massa de 100 sementes, espessura das sementes e submetidas ao teste de germinação. Foram analisadas as porcentagens de sementes duras, de germinação, de embebição e o índice de velocidade de embebição. Pode-se concluir que o estádio de maturação em que ocorre a secagem afeta a intensidade de dormência das sementes de mucuna-preta.Termos para indexação: Mucuna aterrima, permeabilidade do tegumento, embebição das sementes, sementes duras. DORMANCY DEGREE DURING VELVET BEAN SEEDS MATURATIONABSTRACT -The velvet bean (Mucuna aterrima (Piper et Tracy) Holland) is a legume utilized for green manure and as forage. Its seeds have dormancy caused by a seed coat that is impermeable to water. The purpose of this study was to investigate the dormancy degree of the velvet bean seeds during maturation when dried in intact pods. Racemes were harvested, weekly, beginning 35 days after labeling, at the start of flowering (35 DAF), and ending at the dry pod stage (98 DAF). The seeds of each harvest time were dried in intact pods at not controlled laboratory environment conditions; when dried, the seeds were extracted from the pods and the weight of 100 seeds and the seed thickness were evaluated and then submitted to the germination test. The percentages of hard seeds, germination, imbibed seeds and the imbibition rate were analyzed. We concluded that the maturation stage that seeds are dried at affects the dormancy degree of velvet bean seeds.
