helped us in the development of a better growing system for
phytoextraction and the opportunity for the phytomining of nickel in
Albanian ultramafic soils. In order to find the best populations in
nickel phytoextraction and the best harvesting time it is important to investigate the characteristics of different populations of A. murale in
southeastern Albania. As biomass of hyperaccumulator A. murale was
the main contributor in Ni phytoextraction yield this study focuses on
the variation of dimensions of plants and plants organs during
flowering stages of A.murale, in order to evaluate when biomass
production is at a maximum. In the three sites in southeastern
Albania: Rajce, Pojske, Prrenjas we took samples at 3 plots for each
site. At each site of A. murale we collected 25 specimen. Soil samples
were also taken as composite samples collected randomly at different
locations of plant sampling (in a 0.5m radius around the plants) for
each site. We determined, the size of the plants at different time, then
leaves, fruits and flowers for each population. Biomass production was
found to be maximal at end of the flowering stage and at the
beginning of fruiting stage for all populations, while maximal
phytoextraction capacity was found in Pojska populations.
This study show variation in Ni concentration across
populations in each of the plant’s organs and concluded that the end
of the flowering stage and beginning of fruiting stage is the best time
for harvesting. | | Keywords : | | | Alyssum murale, biomass production, flowering stage,
