Thermal time models and predictions for germination of six provenances of Scots pine (Pinus sylvestris) in southern England

Melusi Pro RAMPART

Abstract


There has been little research on the benefits and risks associated with the use of seeds from more southerly seed sources. Temperature requirements and thermal time parameters were determined for six P. sylvestris provenances selected to represent a wide latitudinal range across the species. Distribution and thermal time parameters were used to predict field emergence under current and predicted future climatic conditions for southern England.There were significant differences among provenances in germination capacity. Southern provenances had a higher germination capacity, germinated earlier and more rapidly over a wider range of temperatures than northern provenances.

Keywords: Provenance; climate change; seed source; thermal time model; dormancy
