Flavonoid composition during the ontogenetic cycle was examined in Pyracantha coccinea. The flavonoid profiles of plants at different ages showed marked differences in aerial and hypogeal parts. In the vegetative phase there are flavonoids (flavanones, flavones, and flavonols) only in the aerial parts and they appear gradually during the plant life. These secondary metabolites are detectable in...

This study was carried out to determine effects of different durations (20, 40, 60 days and control) of cold stratification treatments on seed germination and to overcome dormancy in seeds of twelve different drought tolerant plants. The species used in this study were Arbutus andrachne L., Cistus creticus L., Colutea armena Bois. Huet., Cotinus coggygria Scop., Cotoneaster numullaria Fisch. an...
background: the extracts of different parts of plants were found very effective against various pests. the aim of this research was to determine the insecticidal activity of fruit methanol extracts obtained from melia azedarach (meliaceae), phoenix theophrasti (arecaceae), styphnolobium japonicum (fabaceae) and pyracantha coccinea (rosaceae) against the larvae of culex pipiens (diptera: culici...
Assessment of the flammability of ornamental vegetation (particularly hedges) planted around houses is necessary in light of the increasing urbanization of the wildland-urban interfaces (WUIs) and the high fire occurrence in such areas. The structure and flammability of seven of the species most frequently planted as hedges in Provence (southeastern France) were studied at particle level. Spati...
