ABSTRACT
Plants growing in poor soil areas are commonly associated with endomycorrhizal fungi as a
mutualism symbiotic. The fungus takes a role on enhancement of the uptake of soil mineral
nutrients particularly phosphorus, thereby enhancing host plant vigor. Despite some of Bali areas
particularly Karangasem area have poor soil condition, less study on the endomycorrizhal fungi
have been undertaken. The objective of this study are to observe the occurrence and percentage
of indigenous Endomycorrhizal fungi associated with plants commonly planted at Three villages
Abang, Sukadana and Muntigunung. The study was undertaken during six months, which is
the period categorized as the transition between the end of dry and pre-wet season. The root
infection in 14 plants categorized as crop and associated-shaded plants were observed by means
of Grid-line lntersect method. The number of spores was counted by wet sieving and decanting
method. The result showed 12 root plants species were having endomycorrhizal infection. The
colonization presented as vesicle, external hyphae and spore forms. The vesicle forms were not
found during the examination. The percentage of infected roots varied from 24.67 % lo 64.33%
of samples taken from Abang and Muntigunung and 21% - 45.670/o from Sukadana. The number
of spores was also varied from 30 - 45 spores/100 gr of soil. The number of spore found at
Sukadana was higher than those at Abang and Muntigunung. Such variation could be addressed
to the difference of soil texture, in which the soil texture of Abang and Muntigunung were sandy
silt and the soil texture of Sukadana was dried-sandy soil.
Key words: Endomycorrhizae, root colonization, number of spores, Bali
