STIMULATING EFFECT OF ECOFUS PREPARATION DUTING PRESOWING SEEDS TREATMENT OF NORWAY SPRUCE
The influence of aqueous solutions of the drug EcoFus, presowing treatment of seeds of Norway spruce (Picea abies (L.) H. Karst.), harvested in natural stands in Nizhniy Novgorod region. Work is performed in laboratory conditions on the model apparatus for the germination of seeds in accordance with the applicable international and state standards. Suppression of differentiating the influence of external factors on fixed parameters compare between samples provided the General terms and uniformity of technologies for harvesting and processing forest raw materials, the same modes of extraction of seeds from cones not differing storage conditions. The examined seed lots generated in accordance with current regulations and were kept in similar containers under identical conditions: cooling chamber of stationary storage of seeds with a constant temperature of minus 15°C. Tested aqueous solutions of the drug at a concentration of 0.25% and 0.50% at an exposure of 24 hours. The control was made by soaking the seeds in water during the same time. The test metrics provided by the current standard, served as technical germinating ability and germination energy of seeds. Recorded an increase of indicators of technical germination and energy of germination of Norway spruce seeds. Maximum growth values made up 12.38 and 28.81%, respectively. Divergence estimates between the treatment options appeared on the leveled background environmental conditions, which allows to consider them as differences caused by the effect of the test biologically active drug. Analysis of variance confirmed the existence of significant differences between experience and control. The share of influence of the organized factors reached 17.71±6.10% of technical germination and 13.89±6.38% seed vigor.
