MORPHOLOGICAL AND STRUCTURAL CHANGES IN VEGETATIVE AERIAL ORGANS FROM LOTUS CORNICULATUS UNDER THE AIR POLLUTION ACTION IN CEAHLAU NATIONAL PARK (CNP) AND ITS ADJACENT AREA
Abstract
Main research directions worldwide concern the distinguishing of the adaptative response of the individuals to environment modifications which occur under the influence of pollutants. These modifications are manifested at different levels: morphological, structural, ultrastructural and biochemical. This manifests not only by macroscopic deviations from the laws of symmetry, but by modifications in the stomata and hairs (tector and secretor) pattern. The vegetal material was collected during June and July 2006 from different polluted sites (from the adjacent aria of the CNP) and from the park area. The investigations were focused especially on leaves anatomy and morphology. The leaves shapes and dimensions, the variation in mesophyll thickness, the structure of conducting and mechanic tissues, the distribution and the frequency of the stomata and hairs in both upper and lower epidermis was followed.
