Abstract

The diversity of terrestrial plants in Indonesia are very huge, including production crops such as palm oil (Elaeis sp.), teak (Tectona grandis L.), lemon (Citrus limon L.) and Aloe vera. The quality of production crops is influenced by the diversity of soil microorganisms, namely the Arbuscular Mycorrhizal Fungi (AMF). AMF plays an important role in the growth and development of the host plant. This study aims to determine the diversity of AMF in the rhizosphere of some production crops at SEAMEO BIOTROP, West Java. Research methods are soil sampling and preparation, soil sieving, AMF spore extraction and morphological identification. As a result, spore density tends to be uniform in all four plants (3 spores per 10 gram). The highest to lowest relative abundance percentage of spores on Glomus sp. (52.17%), Acaulospora sp. (34.79%) and Gigaspora sp. (13,04%). Soil, host plant and AMF factors affect the diversity of AMF.

Abstract

This research was conducted to determine the effect of temperature on the growth of Trichoderma harzianum. Trichoderma harzianum has functions to prevent the growth of diseases in plants, increase plant growth, and decompose organic matter. The research was conducted at the Phytopathology and Biosystem and Landscape Management Laboratory at SEAMEO BIOTROP, Bogor. The study was analyzed using a Completely Randomized Design (CRD) with different temperature treatments with five replications. The parameter observed was the diameter of the fungus growth after 6 days incubation period. Based on the research results, T. harzianum grew well when the fungus was incubated at 23 °C compared to 40 °C.
