“…Phosphorus doses had no effect on the colonization intensity of the root cortex, nor on the content of arbuscules (Figure 4). Although not confirmed in the present study, increased P availability in the soil commonly leads to decreased mycorrhizal colonization (Nogueira & Cardoso, 2006;Balota et al, 2011;Smith et al, 2011). However, some tree species native to Brazil showed no decrease in mycorrhizal colonization due to increased P availability Mineral composition of the leaves in the soil (Siqueira & Saggin-Junior, 2001), which may be the case of A. sellowiana.…”

-The objective of this work was to investigate the effect of liming and phosphorus fertilization on the growth, mineral composition of the leaves, fruit yield, and mycorrhizal colonization of young feijoa (Acca sellowiana) plants. Treatments consisted of four liming levels -0, 25, 50, and 100% of the dose required to raise the soil pH to 6.5 -and of five levels of P -0, 60, 120, 180, and 240 kg ha -1 P 2 O 5 -, placed in a randomized complete block design, in a split-plot arrangement, with three replicates. The orchard was established in 2010 with the Helena cultivar. In 2012, 2013, and 2014, plant growth was evaluated by measuring trunk perimeter, plant height, and tree canopy width. Mineral composition of the leaves, regarding P, N, K, Ca, and Mg contents, was assessed annually. Mycorrhizal colonization was evaluated in 2012, and fruit yield was determined in 2014. No interaction was observed between the studied factors. P contents had no effect on the evaluated variables. Liming, however, increases plant growth, mycorrhizal colonization, fruit yield, and Ca and Mg leaf contents, besides reducing K leaf contents.Index terms: Acca sellowiana, mineral nutrition, mycorrhizal colonization, nutritional status, phosphorus fertilization, soil acidity.Crescimento, composição mineral, produção e colonização micorrízica de goiabeira serrana em resposta à aplicação de calcário e fósforoResumo -O objetivo deste trabalho foi avaliar o efeito da calagem e da adubação fosfatada no crescimento, na composição mineral das folhas, na produção de frutos e na colonização micorrízica de plantas jovens de goiabeira serrana (Acca sellowiana). Os tratamentos consistiram de quatro níveis de calagem -0, 25, 50 e 100% da dose necessária para elevar o pH do solo a 6,5 -e de cinco níveis de fósforo -0, 60, 120, 180 e 240 kg ha -1 de P 2 O 5 -, dispostos em delineamento de blocos ao acaso, em arranjo de parcelas subdivididas, com três repetições. O pomar foi implantado em 2010 com a cultivar Helena. Em 2012, 2013 e 2014, o crescimento das plantas foi avaliado por meio da medição do perímetro do tronco, da altura das plantas e do diâmetro das copas. A composição mineral das folhas, quanto aos teores de P, N, K, Ca e Mg, foi avaliada anualmente. A colonização micorrízica foi avaliada em 2012, e a produção de frutos foi determinada em 2014. Não houve interação entre os fatores estudados. Os níveis de P não tiveram efeito sobre as variáveis avaliadas. A calagem, no entanto, aumenta o crescimento das plantas, a colonização micorrízica, a produção de frutos e os teores foliares de Ca e Mg, além de ter reduzido o teor foliar de K.Termos para indexação: Acca sellowiana, nutrição mineral, colonização micorrízica, estado nutricional, adubação fosfatada, acidez do solo.

“…Even in the less effective symbioses (Ge or Gm), plants tended to show a growth depression, as illustrated by the quadratic regressions adjustments. Under excessive P, the symbioses may be impaired and induce growth depression in plant likewise in citrus (Nogueira & Cardoso, 2006). Although growth depression in citrus had been verified only at 1,000 mg kg -1 of P, mangaba plantlets exhibited this phenomenon just above 50 mg kg -1 , showing that the mycorrhizal symbiosis in mangaba is much more sensitive to P than in citrus.…”

“…Many researchers have shown benefits of inoculations with AM in perennial crops such as citrus (Nogueira & Cardoso, 2006), coffee (Tristão et al, 2006) and passion fruit (Cavalcante et al, 2001). In general, these effects are more evident when soil P level is deficient.…”

-The objective of this study was to evaluate the mycorrhizal dependency of mangaba tree (Hancornia speciosa) plantlets, under increasing levels of phosphorus fertilization. The experimental design was completely randomized in a 4×5 factorial arrangement with three mycorrhizal fungi inocula -Gigaspora margarita, Glomus etunicatum, or a pool of native mycorrhizal fungi (Acaulospora longula, Glomus clarum, Gigaspora albida, Paraglomus sp.) -, and a nonmycorrhizal control, in combination with five levels of phosphorus applied to the substrate: 0, 25, 50, 75, and 100 mg kg -1. After 180 days of growth, plantlets with inoculation of native mycorrhizal pool produced more shoot and root dry biomass and had higher shoot phosphorus content and accumulation. The noninoculated control showed the lowest values, independently of the phosphorus level. The highest relative mycorrhizal dependency occurred with the inoculation of native mycorrhizal fungi. Plants with mycorrhizal fungi did not respond to phosphorus addition above 50 mg kg -1 . Mangaba tree is highly dependent on mycorrhiza, but the degree of dependency varies according to phosphorus levels and fungal inocula. In general, mangaba tree is more responsive to mycorrhizal fungi inoculation than to phosphorus addition.

“…Such growth decrease was attributed to nutrient competition between plant roots and AMF hyphae in the small soil volume. Growth depression also occurs when the cost of carbon drained by fungi from the plant exceeds the benefits of nutrient uptake via AMF (NOGUEIRA; CARDOSO, 2006, LI et al, 2008, KA-SCHUK et al, 2009. The benefits of this plant-fungus association can also be reduced by light limitation that decrease the photosynthetic rate and consequently the carbon allocation to maintain the symbiosis (GEHRING, 2003, SMITH;READ, 2008), as long as carbon drainage by fungi ranges from 5 to 37% of total daily photosynthetic product (PENG et al, 1993, NIELSEN et al, 1998HO, 2005).…”

This work assessed, under nursery conditions, the effect of arbuscular mycorrhizal fungi (AMF) inoculation on the initial growth of the woody species Heliocarpus popayanensis Kunth in containers of different sizes (nursery tubes of 50 or 250 cm3) containing composted cattle manure or organic Pinus spp bark compost diluted (0 to 100%, each 9%) with low fertility soil. Plants in cattle manure grew more than plants grown in pine bark manure independent of tube size. AMF were more efficient in improving plant growth in 250 cm3 tubes than in 50 cm3 tubes independent of the substrates. Mycorrhizal plants grown in 50 cm3 tubes showed less growth than non-mycorrhizal ones irrespective of the substrates. Nevertheless, this growth depression decreased with an increase of substrates dilution with low fertility soil. In the higher dilutions, growth depression did not occur and there was a positive response to AMF inoculation. In addition, only mycorrhizal plantlets showed some growth in low fertility soil as the sole substrate. These results indicated that AMF affect plantlet growth positively or negatively depending on the combination of substrates, fertility level, and container size.
