This paper deals with the storage of seed of Scots pine (Pinus silvestris L.) in laboratory at about 22°C (relative humidity = 50 % approximately) and in cold room at about 4°C (rel. hum. = 60 % approx.) for three years. The control was dewinged by hand, in order not to injure it mechanically. Two dewingers (a new and an old machine) were used for the other samples, and they caused different amounts of mechanical damage to seed. The investigation has shown that mechanically damaged seed of Scots pine loses its germination capacity earlier when kept at room temperature than when kept under cold storage. Moreover, the higher the amount of mechanical damage to seed, the greater is the decrease in germination percentage during the same period of storage. Thus it is profitable to store seed at low temperature and with as little mechanical damage as possible. In the case of Scots pine, seed could be kept in the winged condition, and be dewinged just before sowing. Storage in air-tight or sealed containers might help to preserve the viability of seed longer than storage in containers where air and moisture have easy access to it.
