Tratamentos pré-germinativos em sementes de Arachis pintoi

Abstract: RESUMONeste Trabalho objetivou-se avaliar o efeito dos tratamentos prévios na germinação e no vigor de sementes de Arachis pintoi Krapov. & W. C. Greg.. O delineamento experimental adotado foi inteiramente casualizado, em esquema fatorial (2 lotes x 7 tratamentos), com quatro repetições. Para isto, foram utilizados dois lotes comerciais de sementes com o pericarpo (frutos) de Arachis pintoi, da cv. Amarillo, que estavam armazenados por seis e 12 meses. Por lote, foram empregados os tratamentos de remoção ou nã… Show more

“…The authors' experience indicates that the pericarp integrity of A. pintoi pods (data not published) is compromised by mechanical impacts during drying, processing, packaging, transportation and planting in a degree that is inversely proportional to its moisture content; such impacts may result in seed exposure to insect and microorganism attacks (Rosseto and Alves, 2008), as well as additional mechanical damages, accelerating its deterioration process. However, increases in moisture content may increase the physiological deterioration degree of seeds as a consequence of the acceleration in its respiratory rate and the development of microorganisms associated with it.…”

“…A remoção do pericarpo do fruto pode aumentar a velocidade de emergência das plântulas, o que é desejável; no entanto, pode causar danos mecânicos às sementes, tornando-as mais expostas a microrganismos, Emergência de plântulas de espécies silvestres de amendoim reduzindo com isso, seu poder germinativo (PEREIRA et al, 1996;ROSSETTO;ALVES, 2008).…”
