An image of plus tree scions being grafted onto rootstock planted out in a future Scots pine seed bank at Alice Holt. Can anyone confirm if the use of four root stock trees is and insurance policy and the best ‘take’ would be the one retained?
The advantage of using this method was a rapid establishment of future seed trees from known high quality ‘plus trees’. Also important was the early prolific coning habit of trees originating from grafts or scions. Tree banks were usually left to cross pollinate freely but could also be subject to controlled work where individual female cones were pollinated with individual male cone pollen to produce a known cross.
