Effects of Plant Extracts on Conidial Germination, Mycelial Growth and Sporulation of Fungi Isolated From Poultry Feed

摘要

Effect of ethanolic extracts of Lawsonia inermis , Azadirachta indica , Vinca rosea , Tagetes patula , Ocimum sanctum , Colocasia antiquorum , Adhatoda vasica , Moringa oleifera , Datura metel and Curcuma longa leaf on conidial germination, mycelial growth and sporulation of Aspergillus flavus , A. niger and A. fumigatus were examined. The conidial germination of A. flavus and A. fumigatus were most inhibited by the extract of L. inermis , while that of A. niger was inhibited by A. indica . Other tested plant extracts have a good effect on conidial germination on the selected fungi. The highest mycelial growth of A. flavus (37 mm) was found in V. rosea , but in case of A. niger and A. fumigatus it (38 and 39 mm) was found in D. metel . The lowest (4, 9 and 6 mm) respectively mycelial growth of these fungi found in L. inermis . The highest sporulation (75 × 104/ ml ) of A. flavus was counted in V. rosea , but in case of A. niger and A. fumigatus those (45 × 104 and 55 × 104/ ml ) were in D. metel and the lowest (5 × 104, 12 × 104 and 9 × 104/ ml ) respectively sporulation of these fungi counted in L. inermis plant extract medium.
