The average age of plants used was 5 years. Results of this study showed that there was a tendency of increased leaf number in plants with the application of secondary metabolite of Trichoderma sp. The increase of leaf number of treatment group was 3-6 leaves, while in the control group it was only 3-4 leaves in 6 months. © Published under licence by IOP Publishing Ltd.
