BIODIVERSITY OF ARBUSCULAR MYCORRHIZAL FUNGI IN AVICENIA ALBA AND AVICENIA MARINA
Mhd. Yusuf Nasution
Abstract
Arbuscular mycorrhizal fungi are a symbiosis between plant roots and fungi. This symbiosis is mutualism, so further research is needed on the diversity of mycorrhizal fungi in plant roots. The plant roots that were the object of this study were Avicennia alba and Avicennia marina. The purpose of this study was to determine the biodiversity of arbuscular mycorrhizal fungi in the roots of the Avicennia alba and Avicennia marina plants. The method used in this study is the observation of the percentage of root colonization by counting the number of fields of view. For spore observation, staining and observation techniques were carried out under a microscope. The results show that the percentage of root colonization is in the moderate range. The number of types of spores found is Glomus sp1, Glomus sp2, and Glomus sp3. The conclusion obtained is that arbuscular mycorrhizal fungi can symbiosis with mangrove roots.
