Effect of Sowing Date on Seed Germination Characteristics of Pinus Brutia in Nursery

In order to consider the effect of sowing date on germination characteristics in seeds of Pinus brutia, a Complete Random block design with four replications and 60 vests per replication was performed and pure seeds of Pinus brutia were planted in two different dates including November 20 and February 1. At the beginning of growth season, germination was recorded every 5 days. Then results of parameters including germination, germination percent, energy, peak value, speed and capacity and survival were calculated in autumn and winter sowing date. The results showed significant effect of sowing date on germination. Suitable sowing date for seeds of Pinus brutia is autumn, which is optimal considering labor force scarcity in winter and decrease in costs.
