Sažetak
The aim of this paper was to research physiological sugar beet seed properties (Beta vulgaris L.) considering seed largeness. The research was being carried out in 1993 and 1994 by using seed of native Os Nada hybrid. This investigation comprised factors which directly affected seed germination as well as yield and quality of sugar beet root. For this purpose the seed was divided into four fractions. After that the speed of water absorption in the swelling process was determined as well as germ lengh and weight, germination dynamics, field germination dependence on seed largeness and sowing depth. It was determined that by sugar beet fruits largeness increasing, absolute weight and germination also were increasing, whereas monogermity was decreasing. Water reception speed was higher with small fruits and smaller fractions seed began to germinate earlier. As the result of the above mentioned, after 5 days germination germs of higher lenght and weight were measured with small seeds in reference to germs from large seeds. The highest field germination was 77% achieved with the largest seeds (over 5.5 mm) at the sowing of 2-3 cm depth. By sowing depth increasing, field germination was decreasing. Germination decreasing was significantly faster with small fractions. Statistically justified the highest sugar yield (above 4 t/ha) gave the variants with seed larger than 3.5 mm at the sowing depth of 2-3 cm and the variant of the largest seeds (above 5.5 mm) at sowing depth of 3-4 cm.
