Zusammenfassung: | A collection of 15 Romanian provenances of Norway spruce has been studied: 13 are natural and originate from Bucovine (north-eastern), Bihor (north-western) and central Romania; 2 others are artificial. They are represented by 118 open-pollinated progenies and compared with 3 standards: 2 French provenances and a polycross. The material was sown in 1979 and planted in 1982 at 2 sites located in the Eastern part of France (Gennes, near Besançon; and Amance, near Nancy). The traits studied here are the height at 10 yr, but burts in 1986, branch angle and forkness.
Quinze provenances roumaines d'épicéa commun d'origines naturelle et artificielle, structurées en 118 familles issues de pollinisation libres, sont testées sur 2 sites (Gennes, près de Besançon et Amance, près de Nancy). Deux provenances françaises, Gérardmer et Chapois, et un polycross sont utilisées comme témoins. Les caractères étudiés sont la hauteur à 10 ans, le débourrement végétatif, l'angle de branchaison et la fourchaison. |
