Abstract
Freshly harvested microtubers produced by Wye and CIP methods were treated with Rindite and then stored at 6 C under continuous light or in dark. After 12 weeks, storage behavior, dormancy break and subsequent sprout growth were assessed. Increased period of Rindite treatment and storage in light caused significant weight loss of microtubers. Greater weight loss was recorded from International Potato Center (CIP) microtubers and those stored in the light versus in the dark. Wye microtubers treated with Rindite for 48 hours and stored under light tended to have more microtubers with 2 or 3 sprouts per microtuber than single sprouts. Fresh weight of sprouts was also greater in Wye microtubers when treated with Rindite for 48 hours and stored under light. Longest sprout length increased with increased duration of Rindite treatment.
Resumen
Tuberculillos recientemente cosechados producidos mediante los métodos Wye y CIP fueron tratados con Rindite y luego almacenados a 6 C bajo luz continua o en oscuridad. Transcurridas dos semanas, se hizo una evaluación del comportamiento en almacenamiento, rompimiento del estado de dormancia y consecuente crecimiento de los brotes. Un aumento en el período de tratamiento con Rindite y almacenamiento bajo luz causaron una pérdida significativa de peso en los tuberculillos. Una mayor pérdida de peso se registró en los tuberculillos del Centro Internacional de la Papa (CIP) almacenados en la luz contra los almacenados en la oscuridad. Los tuberculillos de Wye tratados con Rindite durante 48 horas y almacenados bajo luz tuvieron la tendencia de presentar más tuberculillos con 2 ó 3 brotes que brotes únicos. El peso fresco de los brotes también fue superior en los tuberculillos de Wye tratados con Rindite durante 48 horas y almacenados bajo luz. La longitud de los brotes aumentó con la mayor duración del tratamiento con Rindite.
