Effect of different vitamins on in vitro conidial germination and mycelial growth of Botrytis cinerea. (A) Relative conidial germinations in the vitamin-treated cultures on glass slides expressed as percentage (%) compared to that in non-treated conidia. (B) Relative mycelial growths in the vitamintreated cultures on potato dextrose agar media expressed as percentage (%). Means followed by the same letter are not significantly different at 5% level by least significant difference test. The same letter above bars represented no significant difference between treatments.
