  1. Dissertation – Finnvid Prescher Title: Seed orchards – genetic considerations on function, management and seed procurement. Start: summer 2004 Planned disputation: Friday 070928 Planned focus on P sylvestris in seed orchards, genetics and seeds (less focus on spruce and pollen) Last edit January 2007 Remark: as the dissertation took place as planned and successful 070928, this presentation is only of historic interest, but is sill kept here for documentationary reasons. All manuscripts planned here are now accepted or printed, thus the plans here were successfully completed.

  2. Past history • Finnvid was doctorand for Anders Persson, spruce and pine provenances, in Garpenberg some decades ago. Dag L was pherically involved. That resulted in some papers, which could be part of a thesis, but the current thesis starts from scratch.
