Stimulation of laboratory germination of cotton seeds stored for one and two years by electromagnetic fields
Minka Koleva and Kiril Sirakov
Abstract: Stimulation of germination energy and laboratory germination of cotton seeds, stored for one and two years, of 5 Bulgarian cotton varieties Chirpan-539, Helius, Trakia, Natalia and IPK Nelina, by using electromagnetic fields, was studied. It was found that for all tested varieties, after both seed storage periods and for almost all pre-sowing electromagnetic treatments, germination energy and laboratory germination were higher than the corresponding controls for each variety and storage period. After one- and two-year storage of seeds, the highest germination energy and laboratory germination were found for the Helius variety and variant of treatment 1 [U = (8…5)kV and τ = (15…35)s]. Laboratory germination increased by 19.5% compared to the relevant control, and germination energy increased by 24%
