Dormancy and Germination of Castilla Blackberry Seeds (Rubus glaucus Benth)
We categorized the dormancy and germination of blackberry (Rubus glaucus Benth) seeds from the Germplasm Bank System for Food and Agriculture of the Colombian Nation. A tetrazolium test showed normal seedling production viability, but seed coat impermeability prevented imbibition, which is considered an expression of exogenous dormancy; however, this was released by immersing the seeds in 5.25% sodium hypochlorite for 16 to 21 hours. The treatment was applied to 10 accessions of Castilla blackberry, harvested during the dry and rainy seasons. The seeds were germinated under light and dark conditions. The highest germination counts were obtained with the dry-season-collected seeds incubated in darkness and with the rainy-season seeds incubated under light conditions. Differential germination responses were also independently determined by genotype, incubation conditions (light or darkness) and collecting season.
