The effect of different biological products applied with different doses and exposure time on the germination of Scots pine seeds

The aim of the study was to determine the efficiency of methods enhancing the vitality of Scots pine, Pinus sylvestris L. seed by using biological products of microbial origin such as Agrarka, AgroMIX, and Epin with ۱۰ mL L-۱, ۵ mL L-۱, and ۲.۵ mL L-۱ doses. The exposure time of the seeds were ۳۰ min, ۱ h, ۶ h, ۲۴ h. The examined parameters included germination energy (GE) and germination capacity (GC). The results showed that all the tested methods accelerate germination of the pine seeds; using biological products is the most efficient and recommended method for Scots pine and soaking of seeds not long-term is the most efficient and recommended. The best results for the GE and GE were obtained in the pine using biological preparation at AgroMix ۱۰ mL L-۱ under ۶ h of soaking seeds.
