Influence of growth stimulators on germination energy and ability of scots pine seeds (Pinus Sylvestris L.)

The paper presents the outcomes of the research study of the impact made by the Krezatsin growth stimulator on improvement of sowing qualities of seeds of Scots pine (Pinus sylvestris L.), a tree species growing in the southern forest sites of the Far East region. Results. The germination energy was 73.6-91.3%; the laboratory germinating ability was 81.4-98.9%. The biometric parameters of seedlings have been improved. The most effective improvement of seedling parameters have been observed at the solution concentrations of 1*3*10(-3)-1*5*10(-3).
