Abstract

Betonica bulgarica Degen & Nejceff is a Bulgarian endemic species protected under the Biological Diversity Act and included in the Red Data Book of the Republic of Bulgaria, vol.1. Plants and fungi. Harvested seeds of the plants were collected by using insulators to assist the natural reproduction of the populations. The seeds germination and growth of B. bulgarica were studied in three soils: soil from natural habitat; in California red worms Lombricompost (CRWL) and in soil mixture of 2/3 soil + 1/3 CRWL in laboratory conditions. Leaf characteristics - length, width, petiole length, number of leaves and leaf area were studied. It was found that B. bulgarica was characterized by a prolonged period of germination and low rate of germination - 35.0 %. Best plant growth was seen in a soil mixture of 2/3 soil + 1/3 CRWL. The soil strongly influenced leaf length, leaf width and leaf area - 46.1 to 58.6 % of the total variation

Keywords
