| Abstract | ||
| This work focused on the biological aspects, dealing with morphology, anatomy, taxonomy, karyotype, palynology and biogeography. B. tournefortii is a winter – spring active broad – leaved annual weed. The chromosomes are 2n = 20 and the pollens are isopolar, trizonocolpate and sinuaperturate. Seeds begin to germinate from January and the emerge peak was by the end of February. The optimum temperature for germination was 25 - 30º C. The decreased amount of rainfall badly affects the rate of germination. Floristic composition of B. tournefortii community comprised 32 species (6 monocots and 26 dicots) related 19 families, with Anagallis arvensis, Vicia monantha and Chenopodium murale are the commonest associates. Therophytes are the main life – form spectrum and the Mediterranean (30 %) and Irano - Turanian (25 %) are the major chorotypes. This community spread in well-drained, moist, loamy-sand textured soil and in full sun. The nutritive value of the shoot system was 89.3 Cal. / 100m. Phenols and flavonoids were recorded in ethyl alcohol and chloroform extracts. The different extracts revealed antioxidant and antimicrobial activities. | ||
