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.

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. Penelitian dilakukan dengan menginokulasikan sebanyak 5 gram inokulum FMA (setara 15-30 spora) tersebut pada semai sengon (Paraserianthes falcataria), jati (Tectona grandis) dan meranti (Shorea leprosula).  Pengamatan dilakukan selama 9 minggu dengan mengukur pertumbuhan tinggi dan diameter setiap minggu dan biomasa kering serta rasio pucuk-akar pada akhir pengamatan.  Penelitian dirancang secara acak lengkap dengan 5 perlakuan inokulan dengan tanpa membandingkan antar jenis semai tanaman hutan. Hasil analisa sidik ragam menunjukan bahwa setelah 9 minggu pengamatan, perlakuan inokulum FMA tidak berpengaruh nyata terhadap pertumbuhan tinggi (p<0.40) dan diameter (p<0.59) semai sengon, namun berpengaruh nyata pada pertumbuhan diameter (p<0.09) semai jati dan pertumbuhan tinggi (p<0.06) serta berat kering total (BKT) (p<0.07) semai meranti . Inokulan C2 efektif untuk peningkatan pertumbuhan tinggi semai sengon hingga 5% dan meranti hingga 22%.  Inokulan R2 mampu meningkatkan pertumbuhan tinggi semai jati dan meranti masing-masing sebesar 25% dan 81%;  Inokulan P2 meningkatkan sebesar 23% dan 81%; sedangkan inokulan N2 mampu meningkatkan sebesar 21% dan 53% terhadap pertumbuhan semai jati dan meranti.  Inokulan R2, P2 dan N2 lebih disarankan untuk diaplikasikan pada semai jati, dan meranti, sedangkan untuk tanaman legum seperti sengon lebih disarankan menggunakan inokulan C2.Kata kunci : Inokulum, Fungi Mikoriza arbuskula, Semai tanaman hutan

Abstrak. Ultisol merupakan salah satu tanah marginal yang memerlukan pengelolaan yang tepat untuk meningkatkan kesuburannya. Penelitian ini bertujuan untuk mengetahui pemberian Fungi Mikoriza Arbuskula (FMA) dan kompos limbah kakao terhadap kolonisasi FMA, dan pertumbuhan bibit kakao pada Ultisol. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial dengan dua faktor perlakuan dan tiga ulangan. Faktor pertama adalah jenis FMA yaitu tanpa FMA (F0), Glomus sp (F1), dan Glomus sp. + Gigaspora sp. (F2). Faktor kedua adalah dosis kompos yaitu 0 ton.ha-1 (K0), 20 ton.ha-1 (K1), dan 30 ton.ha-1(K2). Hasil penelitian menunjukkan bahwa FMA berpengaruh nyata terhadap kolonisasi mikoriza, namun tidak berpengaruh nyata terhadap tinggi tanaman  pada 30, 60, 90 HST, diameter batang pada 30, 60, 90 HST, dan luas daun pada 90 HST.  Pemberian kompos limbah kakao berpengaruh nyata terhadap tinggi tanaman pada 90 HST, namun tidak berpengaruh nyata terhadap tinggi tanaman pada 30 dan 60 HST, diameter batang pada 30, 60 90 HST, dan luas daun pada 90 HST.  Kombinasi FMA dan kompos limbah kakao berpengaruh nyata terhadap diameter batang pada 30 HST namun tidak berpengaruh  nyata terhadap tinggi tanaman pada 30, 60, 90 HST, diameter batang pada 60 dan 90 HST, dan luas daun pada 90 HST. Perlakuan FMA jenis Glomus sp. + Gigaspora sp. dan kompos 20 g.pot-1 memberikan pengaruh terbaik terhadap kolonisasi mikoriza dan pertumbuhan tanaman. The effects of arbuscular mycorrhizal fungi and compost of cocoa waste on myccorrhiza colonization, and the cocoa seedling growth on UltisolAbstract. Ultisol is one of marginal soils which requires proper management to increase its fertility. This study aims to determine the administration of Arbuscular Mycorrhizal Fungi (FMA) and cocoa waste compost to FMA colonization, and the growth of cacao seedlings on Ultisols. This research used factorial randomized block design (RBD) with two treatment factors and three replications. The first factor is the type of FMA that is without FMA (F0), Glomus sp (F1), and Glomus sp. + Gigaspora sp. (F2). The second factor is the compost dose which is 0 tons.ha-1 (K0), 20 tons.ha-1 (K1), and 30 tons.ha-1 (K2). The results showed that FMA significantly affected mycorrhizal colonization, but did not significantly affect plant height at 30, 60, 90 HST, stem diameter at 30, 60, 90 HST, and leaf area at 90 HST. Cocoa waste compost has a significant effect on plant height at 90 HST, but no significant effect on plant height at 30 and 60 HST, stem diameter at 30, 60 90 HST, and leaf area at 90 HST. The combination of AMF and compost of cocoa waste significantly affected the stem diameter at 30 HST but did not significantly affect the plant height at 30, 60, 90 HST, stem diameter at 60 and 90 HST, and leaf area at 90 HST. Treatment of FMA type Glomus sp. + Gigaspora sp. and compost 20 g.pot-1 provides the best effect on mycorrhizal colonization and plant growth.

A revegetação de áreas desmatadas de Mata Atlântica pode ser realizada com mudas de espécies florestais nativas inoculadas com fungos micorrízicos arbusculares (FMA). Este trabalho objetivou avaliar o efeito de diferentes substratos, na ausência/presença de inoculação com FMA, sobre o crescimento e conteúdo nutricional de mudas de Colubrina glandulosa Perkins. As mudas foram produzidas em tubetes em casa de vegetação. O delineamento experimental foi inteiramente casualizado, com 12 repetições/tratamento e oito tratamentos: T1 (20% esterco bovino + 80% terra), T2 (20% esterco bovino + 80% terra + FMA), T3 (20% esterco bovino + 60% terra + 20% areia), T4 (20% esterco bovino + 60% terra + 20% areia + FMA), T5 (20% esterco bovino + 60% terra + 20% vermiculita), T6 (20% esterco bovino + 60% terra + 20% vermiculita + FMA), T7 (20% esterco bovino + 60% terra + 10% areia + 10% vermiculita) e T8 (20% esterco bovino + 60% terra + 10% areia + 10% vermiculita + FMA). Aos 30, 65, 93 e 115 dias após a instalação do experimento, avaliou-se a altura (H) e diâmetro do coleto (DC). Aos 115 dias, avaliou-se a massa de matéria seca da parte aérea (MSPA) e raiz (MSR), razão MSPA/MSR, taxa de colonização micorrízica da raiz (%COLRAIZ), Índice de Qualidade de Dickson (IQD), conteúdo de nutrientes (N, P, K) na parte aérea e raiz, e eficiência de absorção de nutrientes (N, P, K). Concluiu-se que o T8 é o mais recomendado, pois proporcionou a produção de mudas com elevados valores para a maioria das variáveis de crescimento e nutrição analisadas. Palavras chave: fungos micorrízicos arbusculares, Mata Atlântica, recuperação de áreas degradadas. AbstractEffects of substrate and mycorrhizal inoculation on the production of seedlings of Colubrina glandulosa Perkins. Revegetation of deforested Atlantic Forest areas can be carried out with seedlings of native tree species inoculated with arbuscular mycorrhizal fungi (AMF). This study aimed to evaluate the effect of different substrates in the absence/presence of AMF inoculation on growth and nutritional content of Colubrina glandulosa Perkins seedlings. The seedlings were grown in plastic pots under greenhouse conditions. The experimental design was completely randomized with 12 repetitions/treatment and eight treatments: T1 (20% cattle manure + 80% soil horizon), T2 (20% cattle manure + 80% soil horizon + AMF), T3 (20% cattle manure + 80% soil horizon + 20% sand), T4 (20% cattle manure + 80% soil horizon + 20% sand + AMF), T5 (20% cattle manure + 60% soil horizon + 20% vermiculite), T6 (20% cattle manure + 60% soil horizon + 20% vermiculite + AMF), T7 (60% soil horizon A + 20% cattle manure + 10% sand + 10% vermiculite) e T8 (60% soil horizon A + 20% cattle manure + 10% sand + 10% vermiculite + AMF). At 30, 65, 93 and 115 days after the beginning of the experiment, we evaluated the height (H) and collar diameter (DC). At 115 days, we evaluated the dry matter of shoot (MSPA) and root (MSR), MSPA/MSR ratio, rate of roots colonization by mycorrhiza (% COLRAIZ), quality index of Dickson (IQD), nutrient content (N, P, K) in the shoot and root, besides uptake efficiency of nutrients (N, P, K). We recommend the treatment T8 because it provided the production of seedlings with high values of most of the growth and nutrition variables analyzed.            Key words: abuscular mycorrhizal fungi, Atlantic Forest, land reclamation.

Abstract: The objective of this work was to evaluate the effect of the use of steel slag as a soil acidity corrective and of mycorrhizal fungi associated with phosphate fertilization on corn plants. The study was performed in a greenhouse, using 3-kg pots with a Typic Haplorthox, in a 4x5x2 factorial arrangement, with four acidity correction treatments (C1, correction with dolomitic limestone at a dose of 4 Mg ha-1; C2, correction with steel slag at a dose of 4 Mg ha-1; C3, correction with a 1:1 mixture of 2 Mg ha-1 dolomitic limestone and 2 Mg ha-1 steel slag; and C4, control, without pH correction), five phosphorus doses (0, 42, 95, 213, and 480 mg dm-3), and the presence or absence of two arbuscular mycorrhizal fungi (Rhizophagus clarus and Gigaspora margarita), with five replicates. Steel slag was efficient in correcting soil pH and providing Ca and Mg for the plants; therefore, it could replace limestone. The inoculation with R. clarus and G. margarita, associated with P doses of 42, 95, and 213 mg dm-3, improved the development of corn plants after 45 days, resulting in greater plant height, stem diameter, leaf area, and shoot and root dry matter.

Mining and processing of manganese (Mn) minerals are activities that may result in the generation of large amounts of wastes and serious environmental impacts. Several strategies have been employed to remediate areas with high Mn concentrations, but many of them imply high investments and high risk of secondary pollution. This study aimed to evaluate the phytostabilization potential of Mimosa caesalpiniaefolia Benth. in Mn mining soil influenced by inoculation with arbuscular mycorrhizal fungi (AMF). The experimental design was completely randomized, with four treatments [not inoculated (control), inoculated with Rhizophagus clarus; inoculated with Claroideoglomus etunicatum and inoculated with Rhizophagus clarus + Claroideoglomus etunicatum (Mix)], and four replicates. Inoculation with Mix and C. etunicatum had higher efficiency in protecting plants against excess Mn, due to the greater retention of this element in the roots and lower translocation to the shoots. Inoculation with R. clarus did not influence plant development and reduction of Mn contents in the shoots. The association of the AMF Mix and C. etunicatum with the species Mimosa caesalpiniaefolia Benth. enhances Mn phytostabilization in mining soils with high concentration of this element. The use of multivariate analyses proved to be an important tool with respect to the behavior of biometric, chemical and microbiological variables in mining soil with high Mn concentration.

High concentrations of copper in the soil are toxic to the development of plants and microorganisms. The aim of this study was to select arbuscular mycorrhizal fungi efficient for the development and yield of soybeangrown in copper-contaminated soil. The experiment was laid out in a completely randomized design with a 7 × 4 factorial arrangement corresponding to seven rates of copper (0, 80, 160, 240, 320, 400, and 480 mg kg-1 of soil) and four inocula (uninoculated control and three mycorrhizal fungi, namely, Acaulospora colombiana, Dentiscutata heterogama and Rhizophagus clarus), in seven replicates. Shoot height; collar diameter; number of grains per plant; shoot and root-system dry mass; leaf area; specific root surface; copper content and accumulation in the shoots, roots, and grain; chlorophyll parameters; and mycorrhizal colonization percentage were evaluated. Inoculation with the arbuscular mycorrhizal fungi Acaulospora colombiana, Dentiscutata heterogama and Rhizophagus clarus increases the phenological and physiological parameters of soybean and its yield when grown in soil contaminated with up to 480 mg kg-1 of copper applied to the soil. The Rhizophagus clarus isolate provides greater development and yield in soybean grown in soil contaminated with up to 480 mg kg-1 of copper applied to the soil, as compared with the other isolates.
