Categorización del Comportamiento de las Semillas de Mortiño (Vaccinium meridionale Swartz) en Almacenamiento a Baja Temperatura

Abstract

A study was conducted to categorize harvest stage, maximun dry weigth and tolerance to desiccation at low temperature storage of seeds of the promising species “andean blueberry”, Vaccinium meridionale Swartz. The aim was to determine the long term conservation possibility of a duplicate of the current Colombian Andean Highland field collection in cool storage rooms, as well as that of newly collected local populations from the mentioned highland region, which are in danger of genetic erosion due to human intervention and the ongoing global climate change. Both maximum dry weight and the highest germination percentages were observed to be associated in seeds extracted from deep purple (fully ripe) berries. The seeds exhibited orthodox storage behavior, which indicates the possibility for long-term cold storage of a duplicate of the current metapopulation of the species in the country. Más...
