Intergrading Among Plants in Relation to the Provenance of Forest Trees

Abstract

IT has long been known that the geographical source of the seed of forest trees is important if a well-grown and healthy plantation is to be achieved and yield a profitable return. For some years experimental plantations of European Larch have been grown by the Forestry Commission from seed of several Scottish and Continental sources. Attention has been focused to an increasing degree on the question of seed provenance in an effort to obtain varieties capable of giving high yields under a variety of soil conditions in different parts of the country and able to withstand frosts and fungal diseases. With the object of stimulating interest in the question, a discussion on seed provenance and local races of forest trees had been arranged between Sections K (Botany) and K* (Forestry) of the British Association at Dundee, but did not take place before the cancellation of the meeting.
