CULTIVATION
Soil tolerances: it adapts to different kinds of
soil, even the most difficult. It can easily
tolerate the lack of water.
Cultivation: biannual / five years harvest. No
need to prune
Trunk: the wood is quite heavy, (basal density
0,31 g/cm3 ), suitable for energy biomass,
plywood, paper industry, pellets.

USE IN PHYTOREMEDIATION
---------------------------------------------Experiment 1--------------------------------------------Contaminants of concern
Exachlorocyclohexane (HCH) isomers
Plant species
Poplar clones: I-214, AF2 and Monviso
Interaction of plant and contaminants:
Tolerant plant (enhancement of microbial
community) / phytoremediation
Phytoremediation
Mechanism involved in phytoremediation:
Phytostabilisation/rhizodegradation/phytoaccumul
ation/phytodegradation/phytovolatilization/
evapotraspiration
Rhizodegradation
Types of microorganisms associated with
the plant
Aerobium bacteria Arthrobacter strains
Laboratory/field experiment
Field experiment
Initial contaminant concentration
Mean of HCH isomers concentration (±S.E.)
in soil samples.
Total HCH: 0,125±0,008,
α-HCH:0,044±0,031;
β-HCH:0,058±0,052;
γ-HCH:0,017±0,002;
δ-HCH: 0.006±0,001
Length of Experiment
One growing season
Post-experiment contaminant content
The table below provides the means of
individual HCH isomers and total HCH
concentrations (± S.E.) in soil and rhizosphere
samples
(ppm)
after
three
treatments.
Post-experiment plant condition
Biomass production of the three investigated
clones was as good as in the uncontaminated
areas.
Soil characteristics
Age of plant at 1st exposure
(seed, post-germination, mature)
Requirements for phytoremediation
(specific nutrients, addition of oxygen)
Contaminant storage sites in the plant
(root, shoot, leaves, no storage)
Reference
The table below provides some physicochemical and biological characteristics of soil
from experimental site
Cuttings
Bacteria inoculation and soil amendment with
commercial compost and with oxygen release
compound (ORC, IXPER® 75C Calcium
Peroxide, Solvay, S.A).
Harvestable plant parts were only slightly
contaminated. Only 10% of samples were
-1
contaminated by a 0.03 mg Kg of the β-HCH
isomer.
