“…Interações microbiológicas que envolvem o crescimento e desenvolvimento são fundamentais em processos de formação das mudas de oliveira, podendo ser encontrado microrganismos como fungos micorrízicos arbusculares, que proporcionam um incremento no desenvolvimento das estacas já enraizadas, aumentando o sistema radicular, bem como a parte aérea das plantas (Ferreira et al, 2015), e também bactérias que promovem o crescimento das plantas por meio de polímeros e hormônios produzidos (Montero-Calasanz et al, 2013). No entanto, a maioria dos estudos envolvendo enraizamento ou crescimento de mudas de oliveira concentra-se em fatores químicos (Porfírio et al, 2016) e poucos são os trabalhos que consideram as interações microbiológicas, essenciais nas etapas iniciais de produção.…”

“…Apesar de poucos estudos relacionados à inoculação de rizobactérias no processo de propagação vegetativa da oliveira, essa pode servir como uma opção alternativa natural aos reguladores sintéticos de enraizamento, atualmente utilizados para a cultivar Grappolo 541, definida em função de seu potencial de produtividade e desenvolvimento na região de estudo Ferreira et al, 2015).…”

“…Similar results were found in the study of AMF inoculation in Passiflora alata seedlings, observing a positive influence on the growth variables, with higher values in shoot dry matter production and height of plants colonized by G. margarita and G. clarum (RITER NETTO et al, 2014). In another study, it was verified that the inoculation of seedlings of olive trees with AMF favors the SDM in relation to noninoculated seedlings (FERREIRA et al 2015). Oliveira, Alixandre and Miranda (2015) studied the inoculation of the substrate with the isolate C. etunicatum and observed that the inoculum promoted the growth and increment of the phytomass of Dipteryx lacunifera Ducke seedlings.…”

“…Several studies have indicated the beneficial effects of AMF inoculation in fruit seedlings, such as blueberry, olive and pitanga (brazilian cherry) (FARIAS et al, 2014;FERREIRA et al, 2015;DALANHOL et al, 2016). Mango seedlings inoculated with AMF presented rooting after 5-6 months with a colonization rate of 50% for subsequent grafting process (RAMANATHAN et al, 2016).…”

ARBUSCULAR MYCORRHIZAL FUNGI IN SEEDLING FORMATION OF BARBADOS CHERRY (Malpighia emarginata D.C.)

The use of beneficial microorganisms such as arbuscular mycorrhizal fungi (AMF) may favor both the growth phase and the stabilization of the seedlings after transplantation. The aim of this study was to evaluate the effect of inoculation of different AMF species on the development of Barbados cherry seedlings from herbaceous and semi-hardwood cuttings. Softwood and semi-hardwood cuttings, previously rooted, were planted in 500 ml tubes filled with Plantmax® substrate and inoculated with three species of mycorrhizal fungi (Gigaspora margarita -Gimarg, Claroideoglomus etunicatum -Claetun and Glomus clarum -Glclar) isolated and combined (Gimarg + Claetun, Gimarg + Glclar, Claetun + Glclar and Gimarg + Claetun + Glclar). The statistical design was completely randomized in factorial scheme 2 x 8 (two types of cuttings and eight types of inoculation, including control without AMF inoculation) with ten replications. The seedlings were kept in a greenhouse for 100 days and height was measured every 15 days to determine the absolute and relative growth rate (AGR and RGR). At the end of the experiment the seedlings were sacrificed and determined height, fresh and dry shoot mass and root and mycorrhizal colonization rate. The results indicate potential for production of Malpighia emarginata D.C. seedlings inoculated with AMF with tendency to reduce the time for transplanting. The Gimarg + Claetun combination promoted higher rates of absolute growth and height of seedlings from herbaceous cuttings. The species Glomus clarum, isolated or associated with C. etunicatum, promoted higher colonization rates in herbaceous and semi-hardwood seedlings, respectively.

“…Numerous studies have been carried out in order to prove the efficiency of mycorrhization in several crops, evidencing the increment in the development of plants inoculated with AMFs, to the detriment of those not inoculated, presenting significant gains in growth and absorption of nutrients, especially phosphorus, due to the increase of the area of root absorption, with their extension by AMFs (BALOTA et al, 2011, FERREIRA et al, 2015, GARCIA et al, 2016.…”

Plant growth promoting microorganisms, such as mycorrhizal fungi, have been widely used in agriculture because they help plants in the absorption of nutrients and water, influencing their growth. The objective of this work was to verify the effect of the mycorrhizal association of Glomus clarum and Glomus etunicatum on the initial growth of the rootstocks Rangpur lime, Swingle citrumelo and Sunki mandarin. The experimental design was completely randomized with a 3 x 4 factorial arrangement, with five replications, corresponding to three rootstocks, four managements: mineral fertilization, inoculation with G. clarum (IGC), inoculation with G. etunicatum (IGE) and Control. The seedlings were produced in greenhouse, using as substrate the vermicompost earthworm, distributed in polyethylene bags, depositing three seeds of each rootstock / bag. The inoculation with mycorrhizal fungi was carried out at the time of sowing (45 spores of each species / bag). The mineral fertilization was divided into two phases: phosphorus application before sowing (40g of single superphosphate / bag); nitrogen application (1.7 g dissolved in 40 ml of water), divided in eight applications of 5 ml of the solution, via irrigation water, manually and weekly; and micronutrients (B, Cu, Fe, Mn and Zn), sprayed manually every two weeks. The following parameters were evaluated: height, stem diameter, number of leaves, shoot dry mass, colonization and mycorrhizal dependence. There was a significant interaction between the rootstocks and treatments applied in this study for most of the evaluated variables. Rangpur lime and Swingle citrumelo obtained higher height and the management that conferred higher height to the rootstocks was the mineral fertilization and IGE. The largest diameter of the stem was reached by Swingle citrumelo and the management that provided the largest diameter was the inoculation with G. etunicatum. Rangpur lime presented moderate mycorrhizal dependence for G. clarum and marginal for G. etunicatum. Mycorrhizal colonization did not show a significant interaction between rootstocks and the management with inoculation. The mycorrhizal association of G. clarum and G. etunicatum was not presented as the best management for the growth of Rangpur lime, Swingle citrumelo and Sunki mandarin, when compared to the mineral fertilization. However, the inoculation of mycorrhizal fungi provided a positive effect on the uptake of some nutrients by the rootstocks, especially K, Mg, N and P.
