The influence of seeds sorting of softwood species on crop quality

Abstract

The result of studies of the influence of seeds sorting of softwood species on their crop quality showed that each size fraction of heavy and average mass meet the requirements i.e. the energy of their germination and sprouting. They should also be used for sowing both in growing large-sized seedlings without prescrivere, and in the production of seeding with closed root sys-tem. It was also found that the light seeds of all size fractions have lower energy of sprouting and lower ground germination capacity that do not meet quality requirements and are not condi-tioned. These seeds are not good for sowing.
