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.

ABSTRACT The use of arbuscular mycorrhizal fungi (AMF) in the production of rootstocks is an alternative to accelerate plant growth. However, their response depends on the symbionts species and environment. This study aimed at evaluating the influence of AMF species [Scutelospora heterogama, Gigaspora margarita, Glomus etunicatum, Acaulospora sp. and a control (non-inoculated)] on the vegetative development of citrus rootstocks {citrange 'Fepagro C37 Reck' [P. trifoliata (L.) Raf. x C. sinensis (L.) Osbeck.] and 'Kumquat' [Fortunella hindsii (L.) Swingle]}. The experimental design consisted of split-plot randomized blocks, with 10 plants per plot and 3 replications. Height, stem diameter, number of leaves, leaf area and fresh and dry root and shoot mass were evaluated. The colonization of AMF in the roots was also assessed, determining the percentage of colonization and density of hyphae, arbuscules and vesicles. The rootstocks showed no difference for the plant growth parameters, in the absence of AMF. The AMF species colonized the rootstocks roots, but were only effective in accelerating the citrange 'Fepagro C37 Reck' growth, especially when inoculated with Scutelospora heterogama, Gigaspora margarita and Glomus etunicatum. The influence of AMF on vegetative development depends on the citrus rootstock species.

Arbuscular Mycorrhizal Fungi (AMF) are known to have potential as biological agents controlling plant pathogens. This study aims to obtain indigenous AMF isolates that can suppress the attack of Sclerotium rolfsii which causes stem rot disease in peanut. The method used is an experimental method with a Completely Randomized Design with 5 treatments, namely A : AMF Glomus sp-3 + S. rolfsii; B: AMF Acaulospora sp + S. rolfsii; C: AMF Gigaspora sp + S. rolfsii; D: Combined AMF Glomus sp-3, Acaulospora sp, and Gigaspora sp + S. rolfsii; E: Without AMF + S. rolfsii (Control). Each treatment was repeated 5 times. The data were analyzed using Analysis of Variance (ANOVA) using the Statistix 8 program and the Least Significance Different (LSD) test at a 5% significance level. The results showed that the isolates of Acaulospora sp and Gigaspora sp were able to increase the resistance of peanut plants to stem rot disease (suppressing the incidence and severity of the disease) reaching 100%. Keywords: Arbuscular Mycorrhizal Fungi, indigenous, salicylic acid, Sclerotium rolfsii.

This study evaluated the synergism between several P-solubilizing fungi isolates and arbuscular mycorrhizal fungi to improve clover ( Trifolium pratense) growth in the presence of Araxá apatite. Clover was sown directly in plastic pots with 300g of sterilized washed sand, vermiculite and sepiolite 1:1:1 (v:v:v) as substrate, and grown in a controlled environment chamber. The substrate was fertilized with 3 g L-1 of Araxá apatite. A completely randomized design, in 8×2 factorial scheme (eight P-solubilizing fungi treatments with or without arbuscular mycorrhizal fungi)and four replicates were used. The P-solubilizing fungi treatments consisted of five Brazilian P-solubilizing fungi isolates (PSF 7, 9, 20, 21 and 22), two Spanish isolates ( Aspergillus niger and the yeast Yarowia lipolytica) and control (non-inoculated treatment). The greatest clover growth rate was recorded when Aspergillus niger and PSF 21 were co-inoculated with arbuscular mycorrhizal fungi. Aspergillus niger, PSF 7 and PSF 21 were the most effective isolates on increasing clover growth in the presence of arbuscular mycorrhizal fungi. Greater mycorrhizal colonization resulted in greater clover growth rate in most PSF treatments. PSF 7 was the best isolate to improve the establishment of mycorrhizal and rhizobia symbiosis.

Effectiveness of mycorrhizal fungi inoculum Arbuskula Growth of seedling Plain Forest         Utilization of mycorrhizae in forestry are often constrained in the availability of inoculum mukoriza that not every moment can be obtained in sufficient quantities and in accordance with the type of crop and land acidity. It required effort to make the inoculant that can anticipate the condition. It has been developed inoculant arbuscular mycorrhizal fungi (AMF), that explores from various acidity land from under the stands of forest plants, namely inoculum R2, P2, N2 and C2-containing AMF of the genus Glomus sp. The study was conducted with 5 grams inokulasi AMF inoculum (equivalent to 15-30 spores) on seedling sengon (Paraserianthes falcataria), teak (Tectona grandis) and meranti (Shorea leprosula). Observations were carried out for 9 weeks by measuring the height and diameter growth of each week and dry biomass and shoot-root ratio at the end of observation. The statistical analysis was complete randomized with design 5 treatment of inoculant without comparing among species of forest plants seedlings. Results of variance analysis showed that after 9 weeks of observation, AMF inoculum treatments did not significantly affect height growth (p <0:40) and diameter (p <0.59) of sengon seedlings, but significant effect on diameter growth (p <0:09) and the growth of teak seedlings higher (p <0:06) and total dry weight (BKT) (p <0.07) seedling timber. C2 inoculant was effective to increase seedling height growth sengon up to 5% and meranti up to 22%. R2 inoculant increased height growth for seedlings of teak and meranti respectively 25% and 81%; Inokulan P2 increased by 23% and 81%, while the N2 inoculant increased by 21% and 53% of seedling growth of teak and meranti. Inoculant R2, P2 and N2 are recommended to be applied to seedlings of teak, and timber, while for legume crops such as sengon more advisable to use inoculants C2.Key words : inoculum, Arbuscular Mycorrhizal Fungi, Forest plants seedling  Abstrak          Pemanfaatan mikoriza di bidang kehutanan sering terkendala pada ketersediaan  inokulum mukoriza yang tidak setiap saat dapat diperoleh dalam jumlah cukup dan yang sesuai dengan jenis tanaman serta keasaman lahan.  Untuk itu diperlukan upaya untuk membuat inokulan yang dapat mengantisipasi kondisi tersebut.  Telah dikembangkan inokulan fungi mikoriza arbuskula (FMA) hasil eksplorasi dari berbagai keasaman lahan dari bawah tegakan tanaman hutan, yaitu inokulum R2, P2, N2 dan C2 yang mengandung FMA dari genus Glomus sp.

Okra is a vegetable crop that has a high selling value and the production of okra is more exported than sold domestically. The demand for okra from year to year continues to increase from various countries, especially Japan, which imports the most okra from Indonesia. Fertilization of phosphorus (P) fertilizer to fulfill nutrients and provision of arbuscular mycorrhizal fungi (CMA) for more efficient and maximum absorption by plants. Phosphorus (P) fertilizer can increase the production and quality of okra. The aim of this study was to determine the combination of treatment of arbuscular mycorrhizal fungi and which dosage of P fertilizer was best to increase the yield of okra production. The design used was a completely randomized design (CRD) with factorial treatment consisting of two factors. The first factor is the dose of arbucular mycorrhizal fungi (CMA) consisting of 4 levels, namely (0; 160; 320; 480) and the second factor is the dose of P fertilizer (75; 100; 125; 150). Parameters observed were plant height, number of leaves per plant, volume of roots, number of fruits per plant, weight of fresh fruit per plant and weight of plant dry corpse. Based on the analysis of variance, it showed that the interaction was significantly different on the variables of root volume, plant height, number of fruits and fruit weight. Based on research, the CMA dose of 320 kg / ha and the dose of 125 kg / ha gave the highest production results.
