Ispitivanje osobina buhača (Chysanthemum cineraiarefolium Vis.) sa priodnih staništa Crne Gore

Abstract

Pyrethrum (Chrysanthemum cinerarifolium Vis.) is endemic plant to Montenegro, Croatia and Albania. Insecticidal pyrethrin compounds (pyirethrin I i II) exxtracted from pyrethrum flowers. As pyrethrum research has been scarce in this country so far our primary objective was to provide data on the morphology and type of habitats of wild pyrethrum ina varius parts of montenegro and data on its introduction into climat conditions of centaral Serbia. The following morphological and productivity parameters were investigated: Cluster width, cluster height, number of shoots and flower – bearing stems, number of flower-heads, fresh and dry weight of roots, stem, leaves and flowers. Determinated and seed germination and pyrethrum content. The results show the pyrethryn mean in the flower be around 0,7% while most favourable properties were found in plant of the Trsteno locality. Precent of pyrethrin was simual in the plants growed in ecological conditions of central Serbia.
