Paper Abstract

The research of seed sowing qualities demonstrates the considerable influence of laser irradiation on seeds of different species that are essential for the forestry of Russian Federation. For experiment, we used seeds of Spruce fir (Pícea ábies) and Siberian larch (Lárix sibírica). The seeds were exposed to radiation of the following wavelengths: 405 nm 500 mW, 450 nm 3000 mW, 532 nm 550 mW, 640 nm 1000 mW. The results show that laser exposure of seeds has positive impact on growth rate, technical germination ability, root formation, and more over on establishment and root formation while grafting. In experiments is obtained increasing germination by 15% and the germination time to 10%.
