The influence of growth stimulators on sawing qualities of seeds and growth of one-year seedlings of Amur ninebark (Physocarpus (Cambess.) Maxim. amurensis)

With the germination of seeds of Amur ninebark ( Physocarpus (Cambess.) Maxim. amurensis ), immersed in a solution of Zircon stimulator, germinative energy was 43-62%, germination - 55-82%. The most effective concentrations of solutions are 1.2.10-3 and 1.3.10-3. Soil dressing of seedlings is more effective in a solution concentration of 1 ml / 5 l.
