Abstract

Cendawan Mikoriza Arbuskula (CMA) adalah salah satu kelompok cendawanyang hidup di dalam tanah, termasuk golongan endomikoriza yang mempunyaistruktur hifa yang disebut arbuskula sebagai tempat kontak dan transfer haramineral antara jamur dan tanaman inangnya pada jaringan korteks akar. Mikoriza terbentuk karena adanya simbiosis mutualisme antara cendawan atau fungi dengan sistem perakaran tumbuhan. Mikoriza arbuskula membentuk asosiasi simbiotik tertentu antara spesies tanaman dalam skala luas termasuk Angiosperm, Gymnosperm, Pterydopyta, dan beberapa Bryopyta, dan skala cendawan terbatas termasuk dalam ordo tunggal, Glomales. Cendawan ini dapat bersimbiosis dengan akar dan mempunyai peranan yang penting dalam pertumbuhan tanaman, baik secara ekologis maupun agronomis. Peran tersebut diantaranya adalah meningkatkan serapan fospor (P) dan unsur hara lainnya, seperti N, K, Zn, Co, S dan Mo dari dalam tanah, meningkatkan ketahanan terhadap kekeringan, memperbaiki agregasi tanah, meningkatkan pertumbuhan mikroba tanah yang bermanfaat bagi pertumbuhan tumbuhan inang serta sebagai pelindung tanaman dari infeksi pathogen akar. Selain itu mikoriza juga digunakan untuk remediasi lahan yang tercemar. Genus yang banyak dijumpai di Indonesia diantaranya yaitu Glomus, Gigaspora, dan Acaulospora.

Abstract

Mycorrhizae are typical structures found in a plant's root system found symbiotic mutualism between fungi (myces) and roots (rhiza). Mycorrhizae have an essential role for plants because they can increase water and nutrient uptake, especially phosphorus absorption. The purpose of this study was to determine the mycorrhizal genera on the roots of parring bamboo plants (Gigantochloa atter) in Sabantang Hamlet, Toddopulia Village, Tanralili District, Maros Regency because there is no scientific information regarding this issue. This research was conducted with the wet filter method or sieving. The isolation of spores from the rhizosphere of Gigantochloa atter samples was carried out by referring to the pouring method and wet sieving using a stratified filter set. Staining techniques were used to observe the colonization of arbuscular mycorrhizal structures in the roots of the sample plants. The results showed that 27 spores were found, consisting of 15 spores of the Glomus genera, three spores of the Gigaspora genera, and nine Acaulospora genera. Observation of the root structure has not shown the presence of vesicular and arbuscular. However, only hyphae and spore structures were found because the mycorrhizal hyphae in Gigantochloa atter have not yet reached the infection stage to form arbuscular or vesicular structures
