Abstract
The effect of activated charcoal (AC) on the germination of botanical potato seeds was tested by applying AC to seeds in petri dishes which had been pretreated with gibberellic acid (GA). A diverse sample of accessions including cultivar and cultivated species germplasm, cultivated species hybrids, wild species, and wild species known for their slow germination was tested. The time required from hydration to75% germination was significantly less for all types of seeds tested when AC was present. Cultivated species hybrids reached75% germination an average of four days sooner, wild species two days sooner, and slow germinating wild species 18 days sooner when AC was present. Only slow germinating wild species’ seeds germinated with significantly more uniformity in the presence of AC.
Resumen
Se investigó el efecto del carbón activado (AC) sobre la germinación de las semillas botánicas de la papa, mediante la aplicación de AC a las semillas, en platos de petri, las cuales habían sido tratadas previamente con ácido giberélico (GA). Se probó una muestra diversificada de nuevas introducciones, incluyendo el germiplasma de cultivares y especies cultivadas, especies silvestres, y especies silvestres conocidas por su lenta germinación. El tiempo requerido desde la hidratación hasta el75% de germinación fue significativamente menor para todos los tipos de semillas probadas cuando se encontraba presente el AC. Los hibridos de especies cultivadas alcanzaron en promedio el 75% de germinación cuatro días antes, las especies silvestres 2 días antes, y las especies silvestres de germinación lenta 18 días antes, cuando se encontraba presente el AC. Solamente las semillas de las especies silvestres de germinación lenta germinaron, significativamente, más uniformemente en presencia de AC.
