Abstract

During 1993, some laboratory tests have conducted to determine the effects of seed size in spring brewing barley on the length of the germ and rootlet (seed fractions were as follows: 2,8 mm , 2,5 mm and 2.2 mm of diameter, respectively). By a statistical analysis of the date on the length of germ and rootlets in spring barley, statistically significant differences were found to be among the fractions tested, and the largest average value was attained by the seed fraction of 2,8 mm, and the lowest one by 2,2 mm. During 1993 and 1994, a trials have established on the selection field, following the split-plot method, to determine the effects of the above seed fractions and unsieved seed as standard in field trials, and two sowing dates, on field germination (the number of emerged plants /m²). The differences in the number of emerged plants /m² found between the two sowing dates were statistically very significant and the larger number of emerged plants/m² was found after the first sowing date. As for the field trial, the differences found in the number of emerged plants /m² among the fractions were statistically very significant. The largest number of emerged plants/m² was attained with the seed fraction of 2,8 mm, and the lowest one with the seed fraction of 2,2 mm, in both years of investigation.
