Cryopreservation of Quercus robur L. embryogenic calli.

Cryo letters, 2006
Embryogenic calli of pedunculate oak (Quercus robur L.) were cryopreserved using direct immersion in liquid nitrogen. The pretreatment consisted of culture on a solid medium with increasing sucrose concentrations (0.25 M for 1 day, 0.5 M for 1 day, 0.75 M for 2 days, and 1.0 M for 3 days), followed by air desiccation of embryogenic calli to 17.3 ...

Modeling the process of desorption of water in oak (Quercus robur L.) wood

Holzforschung, 2004
Abstract The paper describes a three-dimensional model with non-constant coefficients for the heat and mass transport process in desorption of water in wood. The model is based on conservation of mass and energy and uses various parameters obtained by comparing experimental data with numerical results.

Structure and identification of root bark of Quercus robur L.

Trees, 1995
The root bark structure of Quercus robur L. was analysed at different stages of root development and compared to the structure of stem bark. Root bark thickness varied considerably between different roots. Sclereid quantity decreased with increasing distance from the stem, which means it increased with age.

Microclonal propagation of common oak (Quercus robur L.)

Acta biologica, 1991
In vitro growth of common oak (Quercus robur L.) buds taken from seedlings or juvenile plants was studied. Short nodal segments with shoot tips and one or two actively growing axillary buds taken from 10 days to 23 months old plants were used as initial explants.

Acorn Variability in Common oak (Quercus robur L.)

2001
In the work the results of the research concerning the acorn form variability in the common cak (Quercus robur) in Croatia are given. In total 24 populations were analysed, and in each population the analysis of 100 acorns was made. On each acorn, two properties (the length [L] and the diameter [D]) were measured and therefrom the third property - a L ...

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 ...
