Abstract

Arbuscular Mycorrhizal Fungi (AMF) are cosmopolitan is almost found in a variety of ecosystems. Forest fires influence the biological properties of the soil, especially AMF. This research aims to study the status and diversity of AMF in the former soil of forest fires. Samples of soil and roots of plants was taken from the location of the fire in separate incidents during the 5 period and location unburn. Parameters observed that the degree of root infection, spores density and identification of the type of spores. Identification of mycorrhizae conducted at the Laboratory of Soil Biology, Faculty of Agriculture, University of North Sumatra, begin in May until September 2014. Morphology characteristics used to identify the type of AMF is a form of cell wall thickness, presence or absence of substanding hyphae, surface smoothness and spores  reaction to melzers. The results show that an increase in the average density of spores from the field and the results of trapping, for the average percentage of AMF colonization in the roots of plants at 50,65% include grade 3 and 4 or high categories. Found 2 genus, namely Genus Acaulospora and Genus Glomus. Of the field found as many as 35types of spores and trapping results are found as many as 40 types of spores.

Abstract

This research aims to find out the response or effect of arbuscular mycorrhizal inoculation on growth of slow growing plant. This research was conducted in the greenhouse of the Faculty of Agriculture, University of North Sumatra, Medan.This research uses completely randomized factorial design with 2 factors namely mycorrhizal doses (0 g / seed, 5 g / seed, 10 g / seed, and 15 g / seeds) and plant species (glodokan and tanjung). Parameters measured were plant height, plant diameter, leaf number, percentage of root colonization, P uptake, total dry weight, and short root ratio. The results showed the interaction between plant species and dose mycorrhizal not significantly affected all parameters of eachs treatment. Conversely single factor plant species showed significant effect on all parameters of each treatment, but to a single factor dose of mycorrhizal significant effect on the total dry weight and P uptake but no significant effect on the parameters of height, diameter, number of leaves, the ratio of the root crown and root colonization. Different types of plants  will give a different response to growth.Keywords: Mycorrhizal Fungi, Tanjung, Glodokan, Marginal Land
