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.

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.
