The influence of some fertilizers on anatomical structure and the assimilating pigments of Gazania splendens species –’Big Kiss’

Abstract

This paper presents results of the research on the influence of the latest fertilizers on the growth and development of ‘Big Kiss’which belongs to the Gazania splendens species. The research aimed to establish the influence of fertilizers Osmocote®Pro and Blutenzauber on the content of photosynthetic pigments and histo-anatomical structure of the ‘Big Kiss’. The results obtained showed that samples that were fertilized presented an increase of photosynthetic pigments' content compared to the untreated sample. By analyzing the results of all samples, it was noted that the application of Pro Osmocote® fertilizer led to obtaining the greatest total content of assimilating pigments and also the increase of a,b chlorophyll content. Highlighting the structural differences due to the type of fertilizer was made by histo-anatomicalsections at the level of the leaf lamina.
