JAMUR MIKORIZA VESIKULARARBUSKULAR (MVA) PADA RHIZOSFER TANAMAN LANGSAT (LANSIUM DOMESTICUMCORR.) DI LAHAN GAMBUT
ABSTRACT: The Vesicular
Arbuscular Mycorrhizal (VAM) fungi are a mutualistic symbiosis between the
fungi and the plant root. The VAM fungi are capable of improving the plant
growth. Information on the types of the MVA fungi on the roots of the langsat
(L. domesticum) in peatsoil is yet to be known. This research aimed to find out
the types of the MVA fungi and the level of infection on the roots of langsat
(L. domesticum). The research was carried our at the Laboratory of Microbiology
of the Faculty of Mathematics and Natural Sciences, Tanjungpura University from
February to April 2015. The analysis of soil samples were conducted in the
Laboratory of Chemistry and Soil Fertility of the Faculty of Agriculture,
Tanjungpura University. The isolation of soil samples used the wet-sieving and
decanting technique followed by the centrifugation technique. The research
found a total of 232 spores of MVA fungi, consisting of the genera Glomus (10
types), Paraglomus (3 types) and Acaulospora (3 types). The results of
observation on the root preparations found the structures of MVA fungi such as
spores, hyphae and vesicles with the percentage of root infection at 41%, which
fell into to the intermediate category.
