Abstract

In this investigation, the effect of three distances: 22, 19 and 13 cm between the water level and the seed bed on Jacobsen apparatus (referred to in the following text as "water distance"), was studied on the germination of 24 samples of fresh and old Scots pine seed. The results showed that in most of the samples there was a tendency for the germination percentage to be the highest at the shortest water distance used (13 cm), although these differences were significant only in three cases. Also the germination rate was the fastest, at least in the first few days of the test, at 13 cm water distance in several samples. For the practical seed testing work, this study has indicated that it is important to keep the distance between the water level and the seed bed on Jacobsen apparatus constant, in order to obtain comparable germination results.
