PENGARUH INOKULASI FUNGI MIKORIZA ARBUSKULA Glomus clorum, Glomus etunicatum DAN Gigaspora sp. TERHADAP PERTUMBUHAN SEMAI MAHONI DAN SERU

Abstract

A research on the influence of Arbuscular Mycorrhizal Fungi (AMF) Glomus clorum, Glomus etunicatum and Gigaspora sp. inoculation to improve mahoni (Swietenia macrophylla) and seru (Schima walichii) seedlings growth during 4 months was conducted in nursery of PT. Bukit Asam, Tanjung Enim, South Sumatra. Research used four treatment namely G. clorum, G. etunicatum, Gigaspora sp. and control (without inoculation), arranged in Randomized Block Design with three replication. Growth parameters were height, diameter and shoot-root ratio. The result of research indicated that inoculation of G. clorum, G. etunicatum and Gigaspora sp. improved seru seedling growth, as shown by the improvement of their height and diameter. Mahoni, which were inoculated by G. clorum, G. etunicatum and Gigaspora sp., did not show good growth response.
