Cyto-physiological Effects of Aqueous Extracts of Some Weeds and Clove on the Growth of Chinese Faba Bean (Vicia faba L.)

Cytological and physiological effects resulted from aqueous extracts of Aster squamatus, Euphorbia terracina, Euphorbia peplus, Syzygium aromaticum, Acacia pycnantha, Aloe vera, Euryops arabicus and Tamarix aphylla to the growth of Chinese faba bean (Vicia faba L.) seedlings were evaluated. Examined growth parameters including seeds germination percentage and the fresh and dry weights of root and shoot and their length greatly affected by types of extracts during the time course of germination. Among all tested extracts the Syzygium aromaticum (Clove) and Euphorbia peplus extracts found to be mitodepressant and induced noticeable frequencies of traditional chromosome aberration. Those two extracts also caused significant decreases to the length, fresh and dry weights of root and shoot of Chinese faba bean seedling. Euphorbia terracina and Tamarix aphylla extracts caused complete success of seed germination while Aster squamatus, caused noticed stimulation in root length, root fresh weigh (mg/plant) and root dry followed by Euphorbia terracina. Euryops arabicus caused significant stimulation in shoot length, shoot fresh weight, root lenght and in root fresh and dry weight followed by Tamarix aphylla.
