In this study the effect of two plant growth regulators (indolacetic acid, IAA and gibberellic acid, GA3) and also Trichoderma harzianum (T8) on the phytopathogen fungus Fusarium oxysporium (F15) was investigated. IAA and GA3 with 15 and 30 ppm concentration have no significant effect on T. harzianum (T8) growth. The biocontrol activity of T. harzianum on F. oxysporum was slightly decreased by the presence of IAA and/or GA3. Addition of 40 ppm of GA3 to the culture medium of F. oxsporum increased polygalacturonase activity about 100%. A strong increasing effect on chitinase activity (60%) by T. harzianum (T8) was observed in the presence of phytopathogenic fungus F. oxysporum, but 40 ppm IAA and/or GA3 decreased about 47% of chitinase activity of T. harzianum. |
