A discrimination between Quercus robur L. and Q. petraea

2001
In natural populations, Quercus robur L. and Q. petraea (Matt.) Liebl. comprise a morphological continuum due to hybridization and/or an overlap in variation between the two species. In order to obtain diagnostic markers to investigate these morphological intermediate forms, leaf morphology and AFLP were evaluated for their ability to discriminate ...

Evaluating the germination capacity of commercial seedlots of Quercus petraea

2001
Environ 120 000 kg de glands de chêne sessile (Quercus petraea Liedl.) sont collectés chaque automne en France. Une partie doit être stockée d'une année à l'autre pour une production régulière des plants. Jusqu'ici, seuls les tests de germination en laboratoire (8 semaines) sont utilisés pour prédire la viabilité des glands. Afin d'améliorer la gestion

Comparative study of the distribution and phenology of Quercus cerris, Quercus frainetto and Quercus petraea in Bulgarian forests

This study examined the distribution and phenology of forests dominated by Quercus cerris L. (QC), Quercus frainetto Ten. (QF) and Quercus petraea sensu lato (QP) across Bulgaria. Ecological variables, including altitude, latitude, longitude, aspect and slope, were analysed to characterise species-specific habitat preferences. Phenological events, such
