streszczenie
The aim of the experiment was to establish the
influence of biostimulation on the sugar beet seeds. The seeds came
from the specialized breeding program energ’hill or were irradiated
by the laser in two doses. The impact of the biostimulation was
analyzed by determining the nitrate reductase activity and the
nitrate, chlorophyll and carotenoids contents in leaves, as well as,
the dry matter and sugar concentration in mature roots. The field
experiment was established for two sugar beet cultivars. Biostimulation
by irradiation and a special seed breeding program energ’hill
had a positive influence on some examined parameters (particularly
on nitrate reductase activity in Ruveta and in numerous cases
on photosynthetic pigments in both cultivars). Regarding the dry
matter accumulation and sugar concentration this impact was more
favourable for Tiziana than for Ruveta cultivar.
