Résumé :
|
French State seed orchards of Norway Spruce are characterized by low and irregular flowering.It appears obvious that good seed production cannot be obtained naturally and that artificial stimulation of flowering is needed. Former results having shown that Gibberellin 4/7 injection was the best treatment to promote flowering, three experiments were set up (or continued) in 1993 in order to improve hormonal treatment efficiency.
