“…The increase in plant height, number of leaves, and dry mass weight of shoots and roots in plants from AMF treatments may be due to the increase in P and K contents, which was higher than those observed in plants from the inoculation control treatment, at all evaluated N dosages. Similar results have been obtained in sweet passionfruit by Riter Netto et al (2014).…”

Catharanthus roseus (L) G. Don (Madagascar periwinkle) belongs to the Apocynaceace family and is widely spread throughout tropical and subtropical regions of the world. The plant produces several important alkaloids, such as ajmalicine and serpentine, which are used in the treatment of circulatory diseases. The potential of inoculation with arbuscular mycorrhizal fungi (AMF) and nitrogen fertilization to enhance the production of alkaloids was investigated in periwinkle. A greenhouse experiment was carried out to evaluate the effects of arbuscular mycorrhizal fungi and N fertilizer dosages on plant growth, production of ajmalicine, and nutrient content in roots. The concentration of ajmalicine was determined by reverse-phase high-performance liquid chromatography with UV detection. The experiment was designed in randomized blocks in a 4 × 4 factorial scheme with four microbiological treatments (control-without mycorrhiza; Claroideoglomus etunicatum; Rhizophagus intraradices; mixed inoculum-Rhizophagus clarus + Gigaspora margarita), and four N fertilizer dosages (15, 30, 60, and 120 mg kg-1) with four replications. Catharanthus roseus growth was higher when plants were inoculated with mixed inoculum (R. intraradices + G. margarita) and C. etunicatum. The mixed inoculum (R. intraradices + G. margarita) and C. etunicatum, combined with N fertilization, enhanced ajmalicine yield. Catharanthus roseus inoculated with mycorrhiza showed increased P absorption and reduced N content.

“…In contrast, Riter Netto et al [19] developed a study using screens and reported an increase in the foliar content of total phenols in Passiflora alata Curtis inoculated with C. etunicatum , Rhizophagus intraradices , and mixed inoculum ( Rhizophagus clarus and Gigaspora margarita ) in relation to the non-inoculated control. Other field studies that differ from ours indicate that inoculation with AMF provided an increase in these compounds, as recorded in flowers of Cynara cardunculus L. var.…”

“…The accumulation of biomolecules of the secondary plant metabolism in response to symbiosis may be attributed to mechanisms as the improvement of the nutritional condition of the host [18, 19], activation of metabolic routes [21], production of signaling molecules [20], alterations in the activity of key-enzymes for the production of these compounds [20], hormonal alterations [45], increase in the expression of genes involved in the biosynthesis of these biomolecules [22, 45]. Such mechanisms have also been suggested in other studies [8, 38].…”

Background: Libidibia ferrea is a species particular to the caatinga presenting medicinal properties for containing bioactive compounds. The use of Arbuscular Mycorrhizal Fungi (AMF) can increase the production of biomolecules in the legume leaves; however, no light has been shed on the role of symbiosis in maximizing metabolites production in the bark of L. ferrea stem.Objective:The aim was to select AMF that are efficient at increasing the production of phenolic compounds with medicinal properties in the bark of the L. ferrea stem.Methods:The experiment was designed in randomized blocks with four inoculation treatments (plants pre-inoculated with Claroideoglomus etunicatum, with Gigaspora albida, with Acaulospora longula, and non-inoculated plants – control) with six repetitions. Thirteen months after the transplanting, the plants were pruned and the bark of the stem was collected; subsequently, this plant material was dried in a chamber. After the drying process, fractions of the bark of the stem were macerated in methanol. The extracts were further used for analyses of the biomolecules.Results:The flavonoids concentration had an increase of, respectively, 236% and 186% in relation to the control for the treatments with A. longula and C. etunicatum; plants inoculated with A. longula had an increase of 47% in total tannins concentration compared with the non-inoculated control – a benefit that the proanthocyanidins did not present.Conclusion:Applying inoculation with A. longula may be an alternative to increase the production of biomolecules of the secondary metabolism in the bark of the L. ferrea stem in field conditions.

“…An alternative to the preparation of these seedlings is to use AMFs, which have contributed to reduce the production time of several fruit trees such as citrus (Altoé et al, 2008), yellow passion fruit (Cavalcante et al, 2001;Cavalcante et al, 2002), sweet passion fruit (Anjos et al, 2005;Vitorazi et al, 2012), papaya (Lima et al, 2011) and cashew (Weber et al, 2004), in addition to reducing phosphate fertilization (Riter Netto et al, 2014).…”

The success of star fruit cultivation deployment begins with the use of good quality seedlings Thus the inoculation of mycorrhizal fungi in culture seedling can be an alternative, since it was found success in both growth as nutritional aspect fruit species. In this sense, the aim of this study was to evaluate the effects of arbuscular mycorrhizal fungi (AMFs) on growth and mineral composition of star fruit seedlings, cultivated under different doses of phosphorus (P). The experiment was conducted in a greenhouse and the experimental design used was randomized blocks in a 3 x 4 factorial scheme, with three microbiological treatments (without inoculation, Rhizofagus clarum, Glomus etunicatum) and four doses of P (0, 50, 100 and 200 mg kg -1 soil) with four replications. Plants were harvested four months after sowing for biometric and nutritional analysis. In the soil without phosphate fertilization, R. clarum, provided increments of 49% in height, 99% in dry matter production and 86, 129 and 108% in the contents of N, K, and Ca, respectively, in relation to the control. Regardless of phosphate fertilization, the content of P, Mg, and S in the dry matter weight was 19.2, 17.6 and 23.6% higher in the treatment inoculated with R. clarum, in relation to the control. Mycorrhizal dependence of star fruit tree varied according to fungus species and the P dose used, being greater when the fungus R. clarum was used in absence of P.Key words: Averrhoa carambola L.; mineral composition; mycorrhiza Fungos micorrizicos arbusculares e adubação fosfatada em mudas de caramboleira RESUMO O sucesso da implantação do cultivo da caramboleira inicia-se com a utilização de mudas de boa qualidade, nessa linha a inoculação de fungos micorrizicos em mudas da cultura pode ser uma alternativa, visto que foi verificado sucesso tanto no crescimento como em aspecto nutricionais em espécies frutíferas. Nesse sentido, objetivou-se com esse trabalho avaliar a inoculação de fungos micorrízicos arbusculares (FMAs) no crescimento e composição mineral das mudas de caramboleira, cultivadas com doses de fósforo (P). O delineamento estatístico utilizado foi de blocos ao acaso, num fatorial 3 x 4, com três tratamentos microbiológicos (sem inoculação, Rhizofagus clarum, Glomus etunicatum) e quatro doses de P (0, 50, 100 e 200 mg kg -1 de solo) e quatro repetições. As plantas foram colhidas aos quatro meses após a semeadura para análises biométricas e nutricionais. No solo sem adubação fosfatada, o fungo R. clarum proporcionou incrementos de 49% na altura, 99% na produção de massa de matéria seca e de 86, 129 e 108% nos conteúdos de N, K e Ca, respectivamente, em relação ao controle. Independente da adubação fosfatada, o conteúdo de P, Mg e S na massa de matéria seca foi 19,2, 17,6 e 23,6% maior no tratamento inoculado com R. clarum, em relação ao controle. A dependência micorrízica da caramboleira variou de acordo com a espécie de fungo e a dose de P utilizada, sendo maior quando se utilizou o fungo R. clarum na ausência de P. Palavras-chave:Aver...
