The biological role of Cyclamen rohlfsianum to bio-control some plant fungi.

Abstract

The biological activities of Cyclamen rohlfsianum, which is endemic to Al-Jabal Al-Akhdar region, Libya, it's unexplored. Therefore, this study was conducted to test the biological role of extracts of tubers and leaves of aqueous cyclamen and acetone at a concentration of (100 and 200) mg/ml against some plant pathogenic fungi (Fusarium solani, Aspergillus niger, Rhizopus microspores, Botrytis cinerea) by Poisoned food technique. The results showed that all extracts possess a good activity in a control of fungi studied, noted of a tuber extract was more effective than a leaf extract, also, a concentration of 200 mg/ml of an acetone extract was superior in recording the highest inhibition rates, Fusarium solani and Aspergillus niger were the most sensitive to extracts with an inhibition percentage of (80, 69%), respectively, While Botrytis cinerea was the most resistant to all concentrations and extracts. Data in this work concluded that the use of Cyclamen rohlfsianum could be a valid alternative for a bio-control System.
