EFFECT OF SOIL TEMPERATURE AND MOISTURE OVER GERMINATION OF SEED COVERED BY ORGANIC POLYMER
- 1 University of Ruse “Angel Kanchev”, Ruse, Bulgaria
Organic polymers used for seed coating have been reviewed aiming to protect the seeds placed into the soil under unfavorable for them conditions. Organic materials could be important hydrophobic agent in both high moisture and low temperature which could protect seeds from early germination. At the same time polymer film couldn’t be a obstacle for seed germination in favorable environment. Study of the polymers is important issue for the agricultural science and practice. In present work effect of soil temperature and moisture over germination of seed covered by organic polymer have been studied. It has been found that seeds coated with thin layer of organic polymer stead in dormancy under 8⁰ C independently of soil moisture. The polymer doesn’t effect on seeds germination ability as well.
