Abstract

In this investigation the effect of the germination periods of 14, 21 and 30 days was studied on the percentage and the rate of germination of Pinus silvestris and Picea abies seed. Samples from areas lying between 50°N and 68"N latitudes were used. Seed with well-developed embryo and endosperm and with high viability, as well as that with reduced viability due to age or due to poor embryo and/or endosperm development was tested. The results showed that in the former type of seed, a germination period of 14 days may be adequate. However, in the latter type of seed, a longer period (21 or 30 days) may be desirable, so that a sample can attain its maximum germination percentage. It is therefore suggested that in the International Rules for Seed Testing, a germination period of 14 days may not be fixed rigidly for these two species, but be flexible, so that it can be prolonged, if necessary, to suit the requirements of a given sample.
