oai:bibliotecavirtual.unl.edu.ar:article-102562021-05-20T21:01:56Z Physiology of Rhodophiala bifi da germination. FISIOLOGÍA DE LA GERMINACIÓN DE Rhodophiala bifida ACOSTA, M. C. ALCARAZ, M. L. SCARAMUZZINO, R. L. MANFREDA, V. T. Our aim is to contribute to the knowledge of the basic physiological characteristics of the germination and perdurability of Rodophiala bifida seeds. The effect of different temperatures, presence / absence of light, two years of harvest and one of storage, on the final percentage of seminal states was evaluated. By adjusting the germination percentage as a function of time, the following were estimated: Maximum Percentage, Average Time and Germination Uniformity. The seeds showed neutral photoblastism, without dormancy or sanitary problems. Between 7 and 28 °C they exceeded 90 % of germination, in pregnancies and with one year of storage (good perdurability); at 33 °C it decreased by 10 % and coincided with the increase in dead and firm white seeds. Germination dynamics adjust to active function. With the Average Times in the range between 7 and 25 ° C, the Optimum Temperature (25 °C), Base (4.83 °C) and Thermal Time (1666 °Ch). Nuestro objetivo es contribuir al conocimiento de las características fisiológicas básicas de la germinación y perduración de semillas de Rodophiala bifida. Se evaluó el efecto de diferentes temperaturas, presencia/ausencia de luz, dos años de cosecha y uno de almacenamiento, sobre el porcentaje final de estados seminales. Mediante el ajuste del porcentaje de germinación en función del tiempo, se estimaron: Porcentaje Máximo, Tiempo Medio y Uniformidad de Germinación. Las semillas evidenciaron fotoblastismo neutro, sin dormición ni problemas sanitarios. Entre los 7 y 28 °C superaron el 90 % de germinación, en ambas cosechas y con un año de almacenamiento (buena perdurabilidad); a 33 °C disminuyó un 10 % y coincidió con el aumento de semillas muertas y firmes blancas. La dinámica de germinación se ajustó a la función utilizada. Con los Tiempos Medios en el rango entre 7 y 25 °C, se estimó la Temperatura óptima (25 °C), la T. Base (4,83 °C) y Tiempo Térmico (1666 °Ch).
