Model for predicting the seed crop of Picea abies and Pinus sylvestris
The seed crop of Norway spruce ( (L.) H. Karst.) and Scots pine ( L.) is predicted with the help of mean monthly temperatures during MayâAugust one and two years before the flowering year. The prediction models were made separately for Lapland and for the rest of Finland. The models are based on 10-...
