Diversity of Arbuscular Mycorrhiza Fungi (AMF) in the rhizosphere of sugarcane

Abstract

Exploration of AMF types in sugarcane cropping areas is an important and necessary initial study to be able to isolate and identify specific types of AMF that exist. Utilization of AMF is one alternative in overcoming problems in acid soils, because AMF can help plants absorb P elements and other nutrients from the soil. This study aims to identify the types of AMF in the rhizosphere of sugarcane. The research was conducted from June to October 2015, soil sampling was carried out in the community sugar cane garden in Ngemplak Plantation, district Pati (KP. Muktiharjo). While the isolation, identification and capture of spores is carried out in the Ecophysiology Laboratory and the greenhouse of the Indonesian Spices and Medicinal Crops Research Institute, Bogor. The identification results obtained 2 arbuscular mycorrhizal fungi in the sugarcane rhizosphere, namely Glomus sp, (3 species) and Acaulospora sp (1 species). The amount of initial spore density was 120-130 spores per 50 g of soil samples and after trapping, the number increased to 407 spores / 20 g soil samples or increased 6.8 times.
