Study of influence of biological stimulating agents for germination of seeds of belladonna

Abstract

The purpose. Analysis and assessment of efficiency of application of biological stimulating agents of germination of seeds of belladonna dace (Atropa belladonna L.). Methods. Laboratory probes of seeds of 6-years prescription of belladonna dace were carried out in 5 alternatives in 4-fold frequency (100 seeds in each alternative). Field tests were carried out in conditions of stationary experience with total area of sowing lot 20 m2, and registration one — 6 m2. Results. Influence of biological stimulating agents of germination of seeds of belladonna dace is specified. Advantage of gibberelin acid as stimulating agent in comparison with other alternatives is shown. As to quantitative parameters of a flower and fruits of belladonna at use of different stimulating agents for germination the most effective ones were solutions gibberelin and amber acids. Conclusions. The solution of gibberelin acid (A3) 1% has appeared in experiences the most efficient stimulating agent for germination of seeds of belladonna. Thus the applied stimulating agents for germination of seeds essentially did not influence growth and development of plants of belladonna, transition of phenophases by them, formation of the photosynthetic apparatus — leaf blades, amount of flowers and fruits.
