Mycorrhizal colonization was assessed in roots of trees within an Atlantic Forest chronosequence, located in the southeastern of São Paulo State, Brazil, inside Tourist State Park of the High Ribeira Valley (PETAR). The phytosociological survey was carried out in three adjacent areas, all on calcareous soil, which correspond to different time intervals during which they have been left abandoned following a slash-and-burn agricultural perturbation. Early Phase (EP) with 15 years; Mid Phase (MP) with 25 years; and Late Phase (LP) with more than 36 years without clear-cut. The inventory indicated a continuum of tree species substitution, which is dominated by species of Leguminosae, especially Piptadenia gonoacantha (Mart.) J.F. Macbr. (Mimosoideae) in the earlier successional phases. Mycorrhizal colonization, estimated by the occurrence of the mycorrhizal structures in the tree species roots, diminished during the season with less rain (winter), and showed no significant differences between successional phases in the wet season (summer). Rather, the mycorrhizal colonization was correlated with occurrence of the tree’s successional status: being positively correlated with occurrence of pioneer species, and negatively correlated with late secondary species. Mycorrhizal colonization was also correlated negatively with soil organic matter and base saturation. Twenty five species of arbuscular mycorrhizal fungi belonging to four genera were identified. Six species were only identified to generic level. The species Glomus etunicatum Becker & Gerd. represented 10% of the total number of spores and occurred in all phases and seasons, while the genus Glomus represented 57% of the total of spores found in the rhizosphere. The diversity indices evaluated for the mycohrriza community were: H’ = 2.3, J’ = 0.97 and R = 4.12. These results are a contribution to the knowledge of The Atlantic Forest biodiversity and may have implications to support programs regarding rehabilitation of degraded vegetation in one of the World’s most threatened Biomes.

Low Phosphorus

Four western conifers inoculated or not inoculated with three species of vesicular–arbuscular mycorrhizal fungi were grown in pasteurized soil and maintained at 11 or 43 ppm phosphorus. Compared with controls, vesicular–arbuscular mycorrhizal colonization increased biomass more of younger than older seedlings. In young seedlings, species with large seeds responded less to phosphate addition or vesicular–arbuscular mycorrhizal colonization than smaller seeded species. Vesicular–arbuscular mycorrhizal seedlings with low phosphorus were always larger than noninoculated low phosphorus controls and comparable in size or larger than nonmycorrhizal controls at moderate phosphorus. Vesicular–arbuscular mycorrhizal plants produced from 100 to 2000% more biomass than noninoculated plants at low phosphorus, and from equality to 500% at moderate phosphorus. Vesicular–arbuscular mycorrhizal fungal species did not differ in plant growth enhancement or root colonization at any seedling age or phosphorus fertility examined. Tree species' responsiveness ranged as follows: Thujaplicata > Sequoiasempervirens > Calocedrusdecurrens > Sequoiadendrongiganteum. Vesicular–arbuscular mycorrhizal fungi enhanced seedling uniformity and size in all the tree species.

Araucaria or Paraná pine [Araucaria angustifolia (Bertol.) Kuntze, 1898] is an endangered timber tree species of Atlantic Forest that naturally forms symbiosis with arbuscular mycorrhizal fungi (AMF). The objective of this experiment was to evaluate AMF colonization and spore AMF richness in araucaria seedlings produced in nursery at the metropolitan region of Curitiba, Brazil, with the interest of identifying a taxonomical AMF group. For that, soil and fine roots of 6-month-, 1-year-, 2-year-, 3-year-, and 5-year-old araucaria seedlings were sampled and evaluated. Evaluations indicated that araucaria seedlings were well colonized by AMF (with rates varying from almost 50 to over 85%) and produced an abundant number of mycorrhizal spores (from 344 to 676 spores per seedling). Samples contained spores of the species Acaulospora scrobiculata, Dentiscutata heterogama, and Glomus spinuliferum and unidentified species of genera Gigaspora and Glomus. The Glomus genus was the most abundant kind of AMF spores found under nursery conditions. Therefore, the experiment evidenced that Glomus is a promising genus candidate for being used as AMF inoculant in production of araucaria seedlings.

ABSTRACT Paspalum millegrana grass is a member of the family Poaceae native to the Americas, whose interaction with native symbiotic fungi has not yet been reported. The objective of this study was to evaluate the interactions between the native microorganisms and arbuscular mycorrhizal fungi in the development of P. millegrana Schrad. The experimental design was completely randomized with seven treatments (control, without AMF; native microbial inoculant; native + UFLA05 Gigaspora albida; native + UFLA351 Rhizoglomus clarum; native + UFLA372 Claroideoglomus etunicatum; native + UFLA401 Acaulospora morrowiae, and a mix of all treatments). The substrate was autoclaved sand and coconut powder at 2:1, with eight repetitions. The variables analyzed were: mycorrhizal colonization, dark septate endophytic fungi colonization, number of mycorrhizal spores, dry shoot mass, dry root mass, root length and volume, number of tiller and mycorrhizal dependence. Mycorrhizal arbuscular fungi and dark septate endophytic fungi colonized P. millegrana. The sporulation of arbuscular mycorrhizal fungi associated with P. millegrana was influenced by mycorrhizal colonization, depending on the fungus-plant interaction. P. millegrana was responsive to native + UFLA05 and native + UFLA351. No correlation between tiller emergence and mycorrhizal colonization of P. millegrana was observed.

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.
