Percentage of arbuscular mycorrhizal fungi colonization on pidada putih plants (Sonneratia alba)

Abstract

The diversity of AMF in the world is recorded around 250 species associated with plants spread from the tropics to the subtropics and even the north pole (Schussler & Walker 2010). One technique to determine a plant infected with AMF is to determine the percentage of colonization of arbuscular mycorrhizal fungi on plant roots. One of the interesting plants to study is the white pidada (Sonneratia alba) which lives in mangrove areas. This study aims to determine the percentage of colonization of arbuscular mycorrhizal fungi in white pidada plants (Sonneratia alba). The research method used was to follow the sample root staining technique using the staining method from Kormanik and McGraw (1982). Observing the colonization of arbuscular mycorrhizal fungi on the roots of the sample plants was carried out using root staining techniques. The results showed that the percentage of colonization of arbuscular mycorrhizal fungi on Pidada puti (Sonneratia alba) plants, which was 28%, was included in the class 3 category with a colonization percent of 26-50 according to Rajapakse & Miller. Meanwhile, according to O’Connor et al (2001) the above results are included in the medium category with a colonization percentage of 10-30.
