Abstract. Salim MA, Budi RSW, Setyaningsih L, Iskandar, Wahyudi I, Kirmi H. 2020. Root colonization by arbuscular mycorrhizal fungi (AMF) in various age classes of revegetation post-coal mine. Biodiversitas 21: 5013-5022. This study aims to evaluate the status of colonization of the roots of the host plant in various age classes of revegetation of post-coal mining land associated with AMF spores populations and soil fertility. The study was conducted in the post-mining revegetation land at PT. Berau Coal, East Kalimantan. Isolation of the spores was carried out using the wet-sieving and centrifugation method, while the colonization of the roots was carried out by the root coloring technique. Revegetation activities have been able to increase the content of some nutrients in the soil. The AMF population shows tendency an increase along with the increasing revegetation age classes. Eight-year revegetation age classes have the highest average number of spores. Plant species and understorey have shown the existence of AMF colonization with different values for each species. AMF root colonization has a negative relationship with the number of spores in the soil. The C-organic, N-total, CEC Ca, Mg and Fe contents have a positive correlation with AMF root colonization, while available P, total P, K, and Al have a negative correlation with AMF root colonization. Mg was significantly correlated (r = 0.861) to AMF root colonization.

Abstract. Salim MA, Setyaningsih L, Wahyudi I, Budi SW. 2021. Growth of Falcataria moluccana and Albizia chinensis seedling under aluminum exposure. Biodiversitas 22: 3693-3701. Aluminum (Al) is an element found in acid soils and is one of the limiting factors for plant growth. This study aims to examine the growth of Falcataria moluccana (Miq.) Barneby & J.W.Grimes and Albizia chinensis (Osbeck) Merr seedlings under exposure of aluminum. This study used an one-factor completely randomized design (Al concentration) consisting of 5 levels, namely 0, 2, 4, 6, and 8 mM. Each treatment was repeated 3 times and each replication consisted of 3 plant units. The results showed that the Al exposure treatment gave significant differences in the growth of height, root length, dry weight (root, shoot, and total) of F. moluccana and A. chinensis seedlings. The 2 mM Al concentration stimulated the growth of height, root length and dry weight (root, shoot, and total) of A. chinensis seedlings. The tolerance index for F. moluccana and A. chinensis seedlings was highest when the Al 2 mM concentration was 147.55% and 115.32%, respectively. 2 mM Al exposure treatment increased the chlorophyll content a, b, total chlorophyll and carotenoids of F. moluccana and A. chinensis seedlings. Al exposure treatment did not significantly differ from the rate of photosynthesis and MDA content in F. moluccana and A. chinensis seedlings. The Al content in the roots was higher than in the shoots, and the increase in Al concentration increased the Al content in the roots and shoots of F. moluccana and A. chinensis seedlings.
