Efecto de la humedad en el almacenamiento hermetico de semillas de frijol (Phaseolus vulgaris) uri icon

abstract

  • Bean seeds var. Calima were stored in airtight containers during 32 wk., at 30 degrees Celsius and 7 moisture levels between 10.3 and 14.2 percent (humid basis). Every 2 wk., the physical, physiological, and sanitary quality of the seeds was evaluated by doing individual lot samplings of each moisture level. With the exptl. data on germination, emergence, and vigor, mathematical models with regression coefficients (r(2)) of 0.85, 0.93, and 0.77 resp., were obtained. Bean seeds with high initial quality and a max. MC of 12 percent (humid basis) do not undergo significant loss of their physiological quality when airtight stored for up to 8 mo. at 30 degrees Celsius. (AS-CIAT)
