Posters 72 ECOPHYSIOLOGY OF GERMINATION IN SICILIAN POPULATION OF FERULA COMMUNIS (UMBELLIFERAE). Anna SCIALABBA, Giovanna LOMBARDO, Francesco Maria RAIMONDO Dipartimento di Scienze Botaniche, Università degli Studi di Palermo, via Archirafi 38, I-90123 Palermo germas@unipa.it Ferula communis L. is an umbelliferous plant widespread in the Mediterranean basin and particularly abundant in Sicily and Sardinia islands (Italy). In this species, two chemotypes have been distinguished: one is poisonous and responsible of hemorrhagic syndrome of livestock, known as ferulosis, while the other one (non- poisonous) has anticancer activity due to the presence of daucane esters. In Sicily the dry stem of this plant has commercial applications in special manufactured products. The object of the research was to investigate the germination ecophysiology of nine Sicilian populations of F. communis, in order to establish the correct germplasm conservation of the chemotypes economically interesting. In this preliminary study we report data of seeds collected in July 2009 from Monte Pellegrino population. The effects of water (control), three GA3 concentrations (10 -3 , 10 -6 and 10 -9 M) and four temperatures (5°, 15°, 20° and 25°C) were investigated. Besides, seeds were also incubated on MS medium with vitamins, 30 gl -1 sucrose supplemented with three GA3 concentrations (2.8, 5.6 and 11.2 µM) at the same temperatures reported above. Seeds were incubated in the dark and monitored for 120 days. Germination percentage (%G) and mean time germination (MTG) were recorded. The best germination rate assessed was 30% in water at 5°C (69 days of MTG), followed by 10% in water at 15°C (39 days of MTG). Very low germination rate (4.7% and 90 days of MTG) occurred on MS hormone-free medium and on MS with 2.8 and 5.6 µM GA3 at 15°C. No germination was observed at higher temperatures. The results show that low temperatures determine germination while GA3 do not have any inductive effect on germination, in accord with data obtained in Sardinian populations by Sanna and co-workers. Further investigations needs to be carried out to improve the germination protocol of this species. Keywords: chemotype, Ferula communis, germination, germplasm conservation. 8
THE DETERMINATION OF EROSION INTENSITY OF SOIL WHERE THE PLANT ASSOCIATIONS DISTRIBUTED ON SOME MOUNTAINS IN THE TRANSITION ZONES BETWEEN MIDDLE BLACK SEA AND MIDDLE ANATOLIA REGIONS Arzu CANSARAN, Cengiz YILDIRIM Department of Biology, Education Faculty, Amasya University, 05100, Amasya, Turkey arzu.cansaran@amasya.edu.tr, cengiz.yildirim@amasya.edu.tr In this study, the erosion levels of some mountains situated between Middle Black Sea and Middle Anatolia regions are determined related to the data in the analysis tables of plant associations. Erosion and loss of soil related to the erosion is an important environmental problem neglected by the today’s people. The most important factors for the erosion are inclination, climate, vegetation and the structure of the soil. The climate and soil factors can be neglected while determining the intensity of erosion as they don’t show important changes under normal conditions relating to the time. In such a state, vegetation and inclination determine the intensity of erosion. When examining the vegetation, the differences caused by the life length of the plant and the root structures should be taken into consideration. The plant taxa with weak and shallow root structures cannot be expected to prevent erosion. For this reason, “therophytes” and “geophytes” are not considered in determining the intensity of erosion. On the other hand, “phanerophytes”, “chamaephytes” and “hemicryptophytes” can slow the intensity of erosion with their strong root structures. Thus, there is an adverse relation between the coverage percentage of the taxa of these life-forms and the intensity of erosion. However, there is a direct relation between the inclination and erosion intensity. 9 plant associations on the Inegöl Mountain, 8 on the E�erli Mountain, 7 on the Karaömer Mountain and 8 on the Sakarat Mountain are determined by the researchers. Examining the data in the analysis tables of this associations, it is seen that the erosion levels in the distribution areas of the plant associations are 1A: stationary very slight erosion, 1B: sensitive very slight erosion, 2A: stationary slight erosion, 2B: sensitive slight erosion, 3A: stationary mean erosion, 3B: sensitive mean erosion. Keywords: E�erli Mountain, Inegöl Mountain, Karaömer Mountain, Sakarat Mountain, Erosion intensity. 73 9 Posters
