Abstract
The growth and yield in the field of two cultivars of potatoes originating from three different propagation sources — tubers, microcultured shoots (microcuttings) and small tubers produced in culture (microtubers) — were analyzed. Plants originating from microculture produced only single stems emerging from the soil surface whereas tubers formed multistemmed plants. Due to vigorous branching on microcultured plants, however, vine growth appeared similar. Although the total tuber yields were the same for plants from all three propagation sources, in general microcultured plants produced smaller-sized but a greater number of tubers. Microculture is a promising method of producing high quality, certified propagules for potato production.
Resumen
Se analizó el crecimiento y rendimiento de dos cultivares de propagación: tubérculos, brotes micro cultivados (micro esquejes) y pequeños cultivares producidos a través de cultivo (micro tubérculos). Las plantas producidas por medio de micro cultivo produjeron matas de tallos únicos, mientras que los tubérculos produjeron matas de tallos cultivares. Debido al vigoroso crecimiento de las yemas axilares de las plantas originadas en micro cultivo, la apariencia de las matas fue, sin embargo, similar. A pesar de que el rendimiento total de tubérculos fue el mismo para las plantas obtenidas a través de los tres métodos de propagación, las plantas obtenidas por micro cultivo, produjeron tubérculos más pequeños per más numerosos.
El micro cultivo resulta un medio promisorio para la producción de elementos de propagación de alta calidad certificada.
