Abstract

The fungal-related diseases were responsible as one of many reasons for low production of maize in Indonesia. Controlling fungal contaminants using chemical is hazardous for human nowadays. Thus the need of environmental friendly vegetative-based fungicide such as from the extract of Ampupu tree bark is important. The objective of this study was to investigate the antifungal effect from Ampupu tree bark crude extract in response to growth of Fusarium sp, which responsible as the causal agent of corncob rot. The inhibition test on growth of Fusarium sp. by Ampupu tree bark crude extract was performed with diffusion well method on PDA as media. The process involved the infusion of crude extracts at 1.5%, 3.0% and 4.5% concentration, respectively, into diffusion well on each Petri disk. The result showed that by in vivo treatment, crude extract of Ampupu tree bark with concentration of 1.5%, 3,0% and 4.5%, were able to inhibit the fungal growth of Fusarium miniliforme as the causal agent of corncob rot with diameter of inhibition zone 0.18 mm, 1.85 mm and 2.01 mm, respectively. The higher the concentration of the crude extract given, the larger the diameter of inhibition zone formed.

Abstract

Endophytic fungi are found in roots, stems, leaves, flowers, fruit, until rhizosphere in soil area, where the fungus is widely used as an antifungal, biostimulan, antibacterial, and many more. Gemitir is one plant which widely cultivated in some areas in Bali. In Bali this plants use as a material for upakara, ornamental plants and herbs. This study was conducted to determine the type and different kind of endophytic fungi and to see the percentage of endophytic fungal hyphae in the roots, stems, and leaves on gemitir which taken at different locations. Sampling was taken at the Pangsan-Badung, Angseri-Tabanan Regency and Temesi-Gianyar. The sampling method which used is the diagonal method with five sample points. Isolation and identification process was carried out in the Laboratory of Plant Taxonomy (Mycology), State University of Udayana in January-March 2017. In this study of 15 species successfully identified to the genus level that belongs to the six genera namely Alternaria, Aspergillus, Botrytis, Trichoderma, Penicillium and Syncepalastrum. Total of fungal colonies in most samples were found at research location A (Pangsan-Badung Village) and percentage of highest endophytic fungal hypha existed at location C (Temesi-Gianyar Village).

Abstract

The aim of the research was to determine the effect of the combination of Glomus endomycorrhizal and Trichoderma and the appropriate dose to increase the productivity of maize (Zea mays L.). The study was began with the propagation of Glomus endomycorrhizal spores in the green house of the Biology Study Program, Faculty of Mathematics and Natural Sciences, Udayana University and continued with endomycorrhizal spore screening, re-isolation of Trichoderma fungi and application of Glomus and Trichoderma endomycorrhizal spores to corn plants. The results showed that there was no significant difference between positive control (KNO3) and endomycorrhizal and Trichoderma treatments on plant height, number of leaves, root length, ear length, ear diameter, ear wet and dry weight and shell weight and significantly different on the small size of the shells. Doses of 125 Glomus spores and 5 mL Trichoderma give the best results on the small amount of corn shells compared to other doses, so that the combination of endomycorrhizae and Trichoderma can be applied to reduce excessive chemical fertilizers..
