AbstractAgarwood (Aquilaria malaccensis) is one of the non-timber forest products that has high economic value. However, this plant grows very slowly.  Therefore, seed technology input is needed, such as addition of arbuscular mycorrhizal fungi (AMF). The objectives of this research were to study the effect of AMF inoculum i.e. Glomus sp., Gigaspora margarita and mixture of both species on agarwood growth and to determine the best AMF type for agarwood seedlings growth. The experimental research design used was a completely randomized design with three treatments, namely Glomus sp. (G), G. margarita (Gi) and a mixture of Glomus sp. and G. margarita (GGi) and without AMF inoculation (K) with each treatment repeated 8 times. The number of AMF spores used was ± 300 spores/seedling, and applied at the time of transplanting from germination tray to the polybag. Data were processed using analysis of variance and least significant difference test (LSD). The results showed there was AMF colonization in agarwood roots after 12 weeks of inoculation with the highest percentage at 20.50% on G. margarita treatment. Overall, AMF improved the growth of agarwood seedlings. The best seedlings growth was in the treatment of mixed AMF (GGi). Increased growth was found in plant height (14.68 cm), seedling diameter (2.16 mm), leaf area (119.30 cm2), root volume (1.15 mL), total dry weight (0.83 g), and shoot root ratio (4.99).[Keywords: agarwood, A. malaccensis,AMF, G. margarita,Glomussp.]AbstrakGaharu (Aquilariamalaccensis) adalah salah satu hasil hutan bukan kayu yang memiliki nilai ekonomis tinggi.

No Brasil a cafeicultura se expande para regiões mais quentes com a cultivar clonal Conilon ‘BRS Ouro Preto’ da espécie C. canephora. A resposta da ‘BRS Ouro Preto’ à inoculação com fungos micorrízicos arbusculares (FMAs) ainda não foi testada. O presente estudo visou selecionar espécies de FMAs promotoras do crescimento e nutrição fosfatada da referida cultivar. Avaliaram-se três clones (M057, M194 e M199) em três Argissolos Vermelho-Amarelos, coletados em áreas sob: cana-de-açúcar (Solo 1), Cerrado (Solo 2) e Mata Atlântica (Solo 3). Os tratamentos de inoculação foram: Acaulospora colombiana+Glomus sp., Acaulospora scrobiculata, Claroideoglomuse tunicatum+Glomus sp., Dentiscutata heterogama, Gigaspora margarita e Rhizophagus clarus, além de duas testemunhas não inoculadas, uma delas com adubação completa. O primeiro e o terceiro solos proporcionaram maior desenvolvimento vegetativo às plantas. O teor de clorofila e fósforo nas folhas foi maior nas plantas do solo 3. A melhor resposta à inoculação, expressa através do crescimento e nutrição das plantas, foi verificada no solo 1, sendo os melhores tratamentos C. etunicatum+ Glomus sp. e G. margarita. A espécie Glomus sp., presente nos tratamentos A. colombiana + Glomus sp. e C. etunicatum+Glomus sp., apresentou alta esporulação e promoveu o crescimento e nutrição da ‘BRS Ouro Preto’. Os clones M057 e M194 apresentaram maior crescimento, resposta à inoculação e esporulação de FMAs, comparados ao clone M199. Assim, os clones M057 e M194 podem ser considerados micotróficos e promotores da esporulação, enquanto o clone M199 caracteriza-se por baixa micotrofia.

Rehabilitation of post-mining limestone soils is often a challenge due to a lack of nutrients and poor soil humus. The research aims to study the effect of various ameliorants on soil chemical properties, growth, and P uptake of gaharu plant (Aquilaria malaccensis) in post-mining limestone soil for revegetation of critical land. The research was conducted in a Completely Randomized Design with three replications. The treatments were P0 (Control, without ameliorant); P1 (Humic Acid, HA, 4 kg ha-1 ); P2 (Phosphate Rocks, PR, 350 kg ha-1 ); P3 (Vesicular Arbuscular Mycorrhizal Fungi, AMF, 500 spores plant-1 ); P4 (HA+AMF); P5 (PR+AMF); and P6 (HA+PR+AMF). Data were analyzed using ANOVA at 95% confidence level and continued with the LSD test. The use of various types of ameliorants (HA, RP, and AMF) significantly increased root length, root volume, wet and dry weight of roots, shoot wet and dry weight, and P uptake of gaharu tree. The best ameliorant in increasing gaharu tree growth was AMF (P3) treatment, and AMF combined with HA (P4) treatment. Thus, for revegetation of critical land, especially post-mining limestone land, using gaharu tree requires HA and AMF inoculation.

This paper focuses on Eremanthus incanus Less. (Asteraceae), a common species of highland regions in Brazil. The effect of arbuscular mycorrhizal (AM) inoculation on plant growth (height and diameter) was evaluated. Roots were examined from individuals randomly selected from undisturbed areas of highland vegetation and from an experimental restored site. Results showed that E. incanus presented high AM colonization both in restored and undisturbed sites. Moreover, AM colonization was significantly higher in the inoculated treatment than in the non-inoculated one. The species presented Arum-type colonization and frequent production of vesicles, especially in the restored site. Arbuscular mycorrhizal inoculation stimulated plant growth (height and diameter). Ten AM fungi (AMF) taxa were found in the studied rooting zones: Acaulospora spinosa, A. elegans, A. foveata, Acaulospora sp., Gigaspora margarita, Glomus sp., Dentiscutata biornata, D. cerradensis, Dentiscutata sp. and Racocetra verrucosa. These results revealed that AMF is a common and important component in highland vegetation in Brazil, and should be included in future restoration programs.
