A HISTO-ANATOMICAL STUDY OF THE MODIFICATIONS INDUCED BY THIOPHANATE METHYL ON THE CALENDULA OFFICINALIS L. STRAIN
Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2008, Vol 54, Issue 2
Abstract
The effect of the Topsin M fungicide (thiophanate methyl) on the anatomical structure of the Calendula officinalis L. strain is evidenced, comparatively with an untreated sample. The histological modifications caused by this treatment, applied in two different concentrations (of 0.1% and 0.5%, respectively) have the same stimulation effects as those observed in similar experiments. The crosssections, made at three different levels, were performed through the main branches occurring, in the moment of fungicide application, in different stages of development - once known that the morpho-histoanatomical type manifestations of pesticides depend on the extent of tissular differentiation as well as on the development stage of the treated organ.
