RAJIC, M., B. MARINKOVIC and MILICA RAJIC, 2006. Seed dormancy in sugar beet (Beta vulgaris). Bulg. J. Agric. Sci., 12: 621-627

Studied in this paper was how germination energy, germinability and absolute 1000-seed mass of sugar beet seeds was affected by ten different growing locations and seed storage in controlled and uncontrolled conditions for 150 days following harvesting. Over the three study years, significant differences were obtained within each of the factors studied, with no interaction among the factors. The uncontrolled conditions of seed storage in silos produced a highly significant positive difference in seed quality relative to the controlled conditions of laboratory storage. The same difference was obtained with the storage times of December, November and September relative to July. Highly significant differences were found among most of the growing locations, while in a smaller number of them the differences were not significant The significant differences consisted in increased germination energy and germinability and decreased absolute seed mass.

Key words: dormancy of sugar beet seed, germination energy, germinability, absolute 1000 seed mass
