ABSTRACT
The study was conducted to evaluate the antimicrobial properties of the root extracts of some Limonium species, viz. L. effusum, L. globuliferum and L. lilacinum. The root extracts obtained were evaluated against 9 bacteria, and 12 fungi isolated from hazelnut, and walnut. The maximum antibacterial activity was obseved to be in methanol extract. Furthermore, the ethanol extract of L. lilacinum also had the maximum antibacterial activity against L. monocytopenus. The methanol extract of L. lilacinum exhibited the most potent antibacterial activity among the tested extracts. Our findings showed that Limonium root extracts significantly reduced the growth of fungi as compared to control. The inhibitory effects of the Limonium root extracts on the mycelial growth of 12 fungal species isolated from nuts in agar diffusion plate assay showed fungal growth reduced at the 6th day of experiment. The mycelial growth of A. alternata was maximum inhibited (100%) by L. globuliferum water extracts on 6th day.
ABSTRACT
This study was carried out to determine some bioclimatic characteristics such as humidity category (Q2 ), winter variant (m), the length of the dry season (LDS) and the dry season water deficit (DSWD) of naturally growing two endemic oak taxa, Quercus macranthera subsp. syspirensis and Q. petraea subsp. pinnatiloba, living in Turkey. Our findings showed that bioclimatic tolerance range of Q. macranthera subsp. syspirensis’ possess 7 different types of Mediterranean bioclimate while Q. petraea subsp. pinnatiloba had 8 of them. Although Q. macranthera subsp. syspirensis was ranging among the semiarid, freezing and very cold, Q. petraea subsp. pinnatiloba was among sub-humid, freezing and very cold ambient. It was briefly established that Q. macranthera subsp. syspirensis prefers semi-arid and very cold/freezing conditions and Q. petraea subsp. pinnatiloba prefers sub-humid and cold/very cold climatic conditions.
