Methods of Seed Germination Stimulation Exemplified by Seeds of Honey Locust (Gleditsia triacanthos)

Seed germination is a difficult process in some cases because these seeds are covered by a firm testa. The firm testa should be destroyed by means of the following agricultural practices: scarification, stratification, impregnation in boiling water, etc. to increase seed germination. The application of different agricultural practices such as pulse pressure 11 MPa and 29 MPa, scarification, stratification, impregnation in boiling water, the treatment by suspension of rhizosphere microorganism V. paradoxus on seed germination of honey locust were discussed in this article. It was found that scarification, stratification and impregnation in boiling water are effective methods of the firm testa seeds treatment. These methods increased the percentage of seed germination significantly. In addition, seeds with natural cracks had high percentage of germination

The Influence of Processing by Impulse Pressure on the Productivity of the Don Barley (Hordeum vulgare L.)

Plant productivity is the important indicator, which determines the amount of yield. The productivity of plants depends on the number of bruchids per plant and on the weight of 1000 bruchids. The article studies the influence of impulse pressure of various magnitudes on plant productivity of Don barley (Hordeum vulgare L.). It was found that the pressure of 17 MPa was the most effective for increasing the productivity. Impulse pressure of other magnitudes also had influence on the productivity of Don barley
