“…In contrast with the records in this study (Table 2 ), Silva et al [5] verified in greenhouse that the foliar concentration of tannins indicated no differences among the treatments. In L. ferrea established in the field, the foliar concentration of tannins presented no difference caused by mycorrhization [27], such records are different from ours considering that the inoculation provided increase in the concentration of tannins in the bark of the stem of L .…”

“…The medicinal action of L. ferrea is associated with the presence of secondary compounds in the phytomass found in different parts of the plant, such as flavonoids, phenols, tannins, and others [5]. Because of its therapeutic potential, L. ferrea is included in the Relação Nacional de Plantas Medicinais de Interesse ao Sistema Único de Saúde (Renisus - Brazil) [6].…”

“…The optimization in the production of these biomolecules may be achieved through the inoculation of Arbuscular Mycorrhizal Fungi (AMF) [5, 7, 8]. AMF are microorganisms belonging to phylum Glomeromycota [9] that form mutualistic symbiosis with the plants and colonize most of the studied angiosperms and gymnosperms, in addition to some pteridophytes and bryophytes [10].…”

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.

“…The concept of improving the contents respectively the yield of plant secondary metabolites through AMF is recent. For example, the accumulation of flavonoids compounds in medicinal plants colonized by AMF has been reported ( Francineyde, Fábio & Leonor, 2014 ; Hemashenpagam & Selvaraj, 2011 ). Five medicinal herbs inoculated with three AMFs demonstrated that flavonoid contents were enhanced in all of the plants ( Tejavathi & Jayashree, 2013 ).…”

Arbuscular mycorrhizal fungi (AMF) are widely distributed in nature. They live in the roots of higher plants, in a symbiotic relationship. In this study, five commercial species of yams (Dioscorea spp.) were inoculated with six species of AMF, Glomus clarum, G. etunicatum, G. fasciculatum, Gigaspora sp., G. mosseae, and Acaulospora sp., in field cultivation conditions to investigate the influence of AMF inoculation on tuber weights and secondary metabolite content in yam tubers. The results showed that mycorrhizae formation rates ranged from 63.33% to 90%. G. etunicatum inoculation treatment increased the tube weights of the five species of yam tubers by 39%, 35%, 20%, 56%, and 40% for Tainung 1, Tainung 2, Ercih, Zihyuxieshu, and Tainung 5, respectively. The content of secondary metabolites, such as polyphenols, flavonoids, and anthocyanin, was significantly increased by the AMF treatment in tuber flesh and peel of all the tested yam species. Specifically, the maximums exchange of secondary metabolite contents increased to 40%, 42%, and 106% for polyphenols, flavonoids, and anthocyanin, respectively, in the tuber fresh. This study revealed that different species of yam had varying degrees of affinity with various AMF species; selecting effective AMF species is necessary to facilitate yam growth and improve the quality and quantity of yam tubers.

“…They also showed that the inoculation of Ocimum basilicum with F. mosseae increased the amount of essential oil four folds. Silva et al (2014) reported that integrated application of mycorrhizal fertilizers had a more positive effect on the essential oil yield of Mentha piperita, owing to extended root colonization by mycorrhiza. In a3 irrigation, using 25% recommended dose of phosphorus fertilizer alone resulted in a 65.9% increase in the essential oil yield of peppermint.…”

Arbuscular Mycorrhizas and Phosphorus Fertilizer Affect Photosynthetic Capacity and Antioxidant Enzyme Activity in Peppermint Under Different Water Conditions

In order to investigate the effect of arbuscular mycorrhizas and phosphorus levels on photosynthetic capacity and enzyme activity in peppermint under different water conditions, an experiment was conducted during the 2017–2018 growing seasons. The experimental treatments comprised water deficiency at three levels (a1: irrigation after 70 mm evaporation from pan of Class A, a2: irrigation after 110 mm evaporation from pan of Class A, and a3: irrigation after 150 mm evaporation from pan of Class A), phosphorus fertilizer at three levels (without phosphorus fertilization, 25% recommended phosphorus amount, and 50% recommended phosphorus amount), and different mycorrhiza species (nonmycorrhizal inoculation, Rhizophagus intraradices, Funneliformis mosseae, Glomus hoi, and mixture of all three species). Results showed that water stress significantly reduced chlorophyll a, chlorophyll b, total chlorophyll, and essential oil yield, but increased the stomatal resistance of peppermint. The essential oil yield of peppermint was significantly reduced by severe water deficit (a3). However, inoculation with R. intraradices, G. hoi, and a mixture of all three species under severe water deficit, increased the essential oil percentage of peppermint by 21%, 21%, and 31.5%, respectively. Application of 50% recommended phosphorus fertilizer increased the yield of essential oil by 18.9%. In addition, menthol increased by 24.1% (highest) under a3 irrigation, using 25% of the optimal dosage of phosphate fertilizer and nonmycorrhizal inoculation. The maximum catalase and peroxidase activity was obtained in the treatment of G. hoi mycorrhizal fertilizer, after application of 25% recommended dose of phosphorus fertilizer and a2 and a3 irrigation.
