Chalara angustata sp. nov. from roots of Quercus petraea and Quercus robur

Mycological Research, 1996
A new species of the hyphomycete genus Chalara is described. This fungus was isolated several times from roots of healthy and declining oaks (Quercus petraea and Q. robur). It differs from previously described species of Chalara by its septate conidia, the morphology of the phialophores and by colony characteristics.

Insoluble ellagitannins in Castanea sativa and Quercus petraea woods

Phytochemistry, 1991
Sapwood and heartwood samples of sweet chestnut (Castanea sativa) and sessile oak (Quercus petraea) were extracted with aqueous acetone. Ellagitannins were estimated in both extracts and extraction residues, by the Folin-Ciocalteu method and by determination of ellagic acid formed after acid degradation.

Hybridization and speciation dynamic of Quercus petraea and Quercus robur

2012
Quercus petraea and Q. robur are two interfertile sympatric species. They occupy distinct stages during forest succession and constitute therefore good models for ecological speciation studies. Despite their differences, they often grow together in mixed stands, allowing the study of their intra- and interspecific reproductive system.

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
