THE INFLUENCE OF SOME FERTILIZERS AND BIOSTIMULANTS UPON THE ANATOMY OF THE FOLIAR LIMB OF CHRYSANTHEMUM INDICUM L. (IInd NOTE)

Abstract

The results presented in this paper belong to the project “Elaborarea de solutii si tehnici de cultura neconventionale si nepoluante la plantele ornamentale, în contextul dezvoltarii durabile – The elaboration of unconventional and unpollutant solutions and culture techniques, in stable usage context” and presents the testing of three fertilizers and biostimulants (Maxiroot, Dacmarinur Maxi N, Aurora) upon the foliar limb of Chrysanthemum indicum L.; they were applied in 3 variants of concentrations (0.2%, 0.4%, 0.6%). The identification of the impact of the fertilizers has been analyzed by identifying the modifications of the foliar limb and middle vein, a comparative analysis of the number of epidermic cells and stomata which belong to both upper and lower epidermis, as well as measuring the dimension of stomata. In all applied products, a few differences appeared in comparison with the blank sample.
