65  THE EFFECT OF HEAVY METAL CONTAINING WASTEWATER SEDIMENT ON THE MICROANATOMICAL CHARACTERISTICS OF THE LEAVES AND STEM OF SALIX VIMINALIS Csilla Tóth*, György Vincze, Katalin Irinyiné Oláh, Zsuzsanna Uri, Szabolcs Vigh, László Simon Institute of Engineering and Agricultural Sciences, University of Nyíregyháza, Nyíregyháza, HUNGARY *corresponding author: toth.csilla@nye.hu  A comparative microanatomical study of Salix viminalis shoots was performed in order to get an idea of the effect of toxic elements stress on the microanatomical parameters of the shoot (leaves, stem). The examined Salix viminalis shoots originated from Lovász-zug suburban area of Debrecen city, where formerly a sewage settling pond was operated as a secondary biological purification unit. The control Salix triandra x viminalis L. 'Inger' samples originated from the Nyíregyháza experiment with uncontaminated soil. As a result of our reasearch, we can state the following in the case of the leaf samples grown on contaminated soil: the leaf lamina thick-ness decreased; the extent of the palisad parenchima decreased; the extent of the intercellular spaced increased inside the spongy parenchyma; the width and the height of the main veins increased; the extent of the collenchyma bordereing the main vein increased; the stomatal den-sity increased both in the case of adaxial and abaxial epidermis; the size of the stomas decreased. In the case of the stem samples we observed the following: in the case of the samples grown on contaminated soil the extent of the primer cortex increased; the cell wall of the cells building the sclerenchimatic fibers thickened; the number of Ca-oxalate crystal rosettes and sclerids in-creased; the extent of secondary phloem – mainly the extent of hard phloem - increased; the lumen of the tracheas in the secondary xylem increased; the avarage width of the annual rings deacreased; the extent of the central stele of the stem increased.
