Photoactivation of gibberellin influenced by laser radiation on the surface of plant tissues

Researches are directed on studying of the biological processes caused by violet (k = 405 nanometers) and red (k = 640 nanometers) laser radiation on seed integumentary layers. A cycle of experiments was carried out to study the dependence of Picea abies (a fir-tree ordinary, family pine) seed sowing qualities from the influence of laser radiation in different conditions. After being exposed by laser influence, seed germinating ability and seedling growth were studied and compared with the indexes of control group. Results showed that the radiated seed germinating ability is higher, than the one of control group of seeds.
