تقييم كفاءة بعض المستخلصات النباتية والظروف البيئية في نمو الفطر Fusarium oxysporium

Abstract

This study was aimed to evaluat the efficiency of water and alcoholic plant extracts of The following plants: Hibiscuss sabdariffa L., Glycyrrhiza glabra L., Foeniculum vulgare L., Nigaella sativa L., Salvia officinalis L., Origanum vulgare L., Teucrium polium L., Cuminum cyminum L., Artemisia herba-alba L., Cressa cretica L., and Dianthus caryophyllus L. on the growing of the fungus Fusarium oxysporum, where results showed that aqueous hot efficiency at the concentration of 25% for each of the D. caryophyllus L., C. cyminum L., T. polium L. and H. sabdariffa L. as inhibition ratios reached to 80.63 , 84.68 , 85.94 and 80.66 respectively, while the alcoholic extracts had given for each H. sabdariffa L. caused inhibition percentage reached to 100% at concentrations of 20 and 25% and D. caryophyllus L. in all concentrations except 5%. The results showed a large discrepancy between the effect of water and alcohol extracts in the inhibition ratios. the results revealed a positive chemical for each C. cyminum L. extract and G. glabra L. extract in the presence of all effective compounds. While the environmental conditions showed the best temperature for the growth of the fungus was of 26 ° C as diameter of the colony fungal 7.57 cm at the sixth day of incubation and the best pH number was at 7 the diameter of the colony fungal was 7.76 cm.
