Abstract/Contents: | Seeds of 7 small-seeded legume spp., winter oats, rye and perennial ryegrass were exposed to 39 MHz electric fields for 0-26 s, resulting in seed temp. of 39-86 deg C and then stored at ambient temp. or at 4 deg and 50% RH. The radiofrequency (RF) treatments significantly increased germination percentage of lucerne, red clover and Ladino clover by reducing hard-seed percentages. These increases were retained in temp. and humidity-controlled storage for 14 yr. At ambient temp. differences in the effect of treatments tended to disappear as hard seed became more permeable with age. RF treatments reduced post-harvest dormancy in winter oats. Longevity of winter rye seed was not affected by RF treatment. |
