STATUS DAN KENEKARAGAMAN FUNGI MIKORIZA ARBUSKULA (FMA) PADA TANAH BEKAS KEBAKARAN HUTAN DI KABUPATEN SAMOSIR
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.
