Abstract
Effective germplasm conservation through seed banking requires that the viability status of every accession in the seed bank be known. This is normally done by conducting a germination test but is, at times, constrained by the presence of seed dormancy in some of the species. While dormancy release protocols have been developed for a majority of species, the same are lacking for others. The objective of this study was to determine the dormancy releasing procedure of selected species in the family Amaranthaceae to develop a germination-testing protocol for them. In this study, the influence of chilling, incubation temperature, potassium nitrate (KNO3), and dehusking was investigated for 10 wild species. The effect of temperature on seed germination of species in the family was found to be significant (p ≤ .05) with most species performing better at alternating temperatures of 35°C/20°C as compared with constant ones. The effect of dehusking was highly significant on seed germination with the removal of see...
