The Interaction between Heavy Metals Concentrations in Foliar Tissue of Aesculus hippocastanum L. Species within Climatic Conditions of Cluj-Napoca.

Chestnut is a shrub species that belongs to the family Sapindaceae and subfamily Hippocastanoideae. It plays an ornamental plant role along with many other species, in many green areas located mainly in urban spaces. The purpose of our trial carried out by us is to determine the interactions that occur between Cu, Zn, Pb, Cd, Ni quantified in the leaves of the Aesculus hippocastanum L. trees used as ornamental trees in the municipality of Cluj-Napoca, in the climatic conditions characteristic of the area. Multiple strong correlations were identified between the heavy metals taken in the study, respectively Cu, Zn, Pb, Cd, Ni, in the leaves of the studied Aesculus hippocastanum L. trees, in the vast majority of the experimental locations, these being between 0.699 - 0.879. A very strong multiple correlation (R = 0.907) is reported for the experimental location no. 2, related Boulevard 1 December 1918, suburban type location. [ABSTRACT FROM AUTHOR]
