The influence of ozonization of seeds on growth and development of flax plants (Linum usitasimum L.)

The effect of an ozone treatment on the intensity of growth processes in flax seeds was studied at FGBOU VPO “Nizhegorodskaya State Agricultural Academy”. The testing dozes of ozone were 90-750 mg·min/m 3. The results showed the stimulating effect of such treatment. The deviation percentage at control samples at studying dozes was 14±2 % on germination. An inhibiting effect is noted for treatments with ozone dozes more than 6000 mg·min/m 3. In field the best germination was shown by the samples treated with ozone doze D = 190 mg-min/m 3 - 68% (germination of control seeds was 60+3%). The indicators of plant growth and height were the best and seed yield was the highest at plants of flax when seeds for sowing were treated with ozone doze D = 190 mg·min/m 3. Thus, this doze can be considered as an optimal treatment. The biochemical analysis of harvested seeds showed that a sharp decrease of sugar and starch contents was observed at samples treated with D = 190, and an increase of sugar content and a decrease of starch content was stated for samples treated with D = 6000.
