Quercus robur as a Potential Cd Phytostabilizator

Russian Journal of Plant Physiology, 2020
Pedunculate oak (Quercus robur L.) is one of the most important forest tree species in Europe, from both economic and ecological perspectives. Several studies indicate the possibility of using different species of the genus Quercus for afforestation of lands affected by industry, including trace-element polluted areas.

Common oak ( Quercus robur ) acorn as a source of natural coagulants for water turbidity removal

Industrial crops and products (Print), 2018
The potential of whole fruit of acorn and its cotyledons and coat to be used as sources of coagulation active components was studied. Water extracts of whole fruit, cotyledons and coat were the most efficient at 35 NTU. Crude extracts of acorn cotyledons

Investigation of kernel oils of Quercus robur and Quercus cerris

Chemistry of Natural Compounds, 2004
The kernel oils of Quercus robur and Quercus cerris were obtained by Soxhlet extraction using petroleum ether. Oil yields were found to be 5.2–5.6% and 4.3–4.8% for Q. robur and Q. cerris kernel, respectively (expressed in g per 100 g of dried plant material).

CLONAL PROPAGATION OF COMMON OAK (QUERCUS ROBUR L.)

Acta Horticulturae, 1991
In vitro growth of common oak buds taken from seedlings or juvenile plants was studied. Short nodal segments with 1 or 2 axillary buds and shoot tips were used as initial explants. Rapid multiplication of axillary shoots has been achieved on GD medium containing low level of cytokinin (0.9 µM BA).
