Abstract. 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.

 

Key words: seed germination, testa, scarification, stratification, honey locust.
