Status mikoriza hutan pantai dan hutan mangrove pasca tsunami studi kasus di Nanggroe Aceh Darussalam dan Nias

Abstract

This research aimed 1) to study status of arbuscular mycrorrhizal fungus (AMF) in mangrove and coastal forest post tsunami disaster, 2) to study the relationship of soil phosphorus content and number of AMF spores and AMF infection of mangrove and coastal forest post tsunami disaster. Research results show that there were variability in spore numbers in the field studied. The spore numbers in mangrove forest were found as 359, 235, 118 and 160 spores per 50 g of soil in Meulaboh, Banda Aceh, Pidie and Nias respectively. Meanwhile, in coastal forest were 587, 297, 265 and 158 spores per 50 g in Meulaboh, Banda Aceh, Pidie and Nias respectively. The root of Rhizophora sp. and Casuarina equisetifolia found colonized by AMF both in mangrove and coastal forest. Number of spores were negatively correlated to soil phosphorus content, however, there were tendency positive correlation between root infection and soil phosphorus content.
