Determinación de las condiciones de germinación y el efecto de pretratamientos en semillas de Cuphea glutinosa (Lythraceae) Cardinali, Francisco J. Thevenon, Mario A. Murcia, Mónica L. Di Santa, María E. Dormancy scarification stratification gibberellic acid potassium nitrate alternating temperatures darkness. Dormición escarificación estratificación ácido gibérelico nitrato de potasio alternancia de temperaturas oscuridad. : Determination of germination conditions and the effect of pretreatments in Cuphea glutinosa seeds (Lythraceae). Cuphea glutinosa shows a high agronomic and agroindustrial potential. Germination conditions for this species are unknown. The objective of the work is to determine germination conditions, their impairments and the treatments to overcome them. There were utilized healthy seeds, complete and quite filled, gathered from a population of Sierra de los Padres, Buenos Aires province, Argentina. There were applied the following treatments, in six repetitions of 50 seeds, in a completely randomized design: blank, scarified, gibberellic acid, darkness, potassium nitrate, stratification and temperature alternation. The germination conditions after the pre-treatments were 24 °C (+/-1) under light, 100 µE.m-2.sec-1. The counts of emerged rootlets were performed at 6 and 12 days, except for the treatment with darkness, in which they were performed at 12 and 18 days. The effect of the treatments was evaluated by ANOVA and Tuckey tests (p = 0,05). The population showed 50 % of germination; positive response to light, to stratification, and to potassium nitrate. There was no effect with scarification neither with temperature alternation. The gibberellic acid showed a negative effect in the percentage of germination, and affected the carbon partition during the growing of seedlings Cuphea glutinosa presenta alto potencial agroindustrial y agronómico. Se desconocen las condiciones de germinación para la especie. El objetivo del trabajo es contribuir a determinar condiciones de germinación, impedimentos para la misma y tratamientos para superarlos. Se utilizaron semillas sanas, enteras y llenas, recolectadas de una población de Sierra de los Padres, provincia de Buenos Aires, Argentina. Se aplicaron los siguientes tratamientos en 6 repeticiones de 50 semillas, bajo un diseño completamente aleatorizado: testigo, escarificado, ácido giberélico, oscuridad, nitrato de potasio, estratificación y alternancia de temperaturas. Las condiciones de germinación después de los pre tratamientos fueron a 24 °C (+/-1) con luz, 100 µE.m-2.seg-1.Los recuentos de radículas emergidas fueron a los 6 y a los 12 días, excepto en el tratamiento oscuridad en el que fueron a los 12 y a los 18 días. El efecto de los tratamientos se evaluó mediante ANOVA y Tuckey (p = 0,05). La población mostró 50% de germinación; respuesta positiva a la luz, a la estratificación y al nitrato de potasio. No tuvieron efecto el escarificado ni las temperaturas alternas. El ácido giberélico tuvo un efecto negativo en el porcentaje de germinación y afectó la partición de carbono durante el crecimiento de las plántulas.
