Mycorrhizal Inoculation

The increase of the concentration of secondary compounds in medicinal plants can be influenced by the association with arbuscular mycorrhizal fungi (AMF). Pharmacological studies have shown that secondary compounds, found ing Libidibia ferrea (Mart. ex Tul.) L. P. Queiroz, confer phytotherapeutic potential to the species due to antidiabetic, antibiotic and anticancer activity. Therefore, the aim of this work was to verify if the presence of AMF associated or not with phosphate fertilization has an effect on the concentration of foliar phenolic compounds with antioxidant activity in L. ferrea seedlings. The seedlings were transferred to pots with 1.2 kg of soil with phosphate fertilization (P2O5) or not. In the roots was deposited soil-inoculum, containing 300 spores {100 spores of each AMF species: Claroideoglomus etunicatum, Gigaspora albida and Acaulospora longula Acaulospora longula. The plants were maintained in greenhouse for seven months. AMF favored an increase in shoot dry matter production, accumulation of flavonoids and greater total antioxidant activity, dispensing fertilization of the soil. The mycorrhizal inoculation associated with phosphate fertilization maximized the biosynthesis of total chlorophyll and soluble carbohydrates. AMF inoculation presents as a possible biotechnological alternative to increase antioxidant activity and foliar flavonoid production in L. ferrea seedlings, avoiding expenses with agricultural inputs, such as phosphate fertilization, making phytomass more attractive for the production of phytotherapics.

Alternative Cultivation

Saffron (Crocus sativus L.) is cultivated worldwide. Its stigmas represent the highest-priced spice and contain bioactive compounds beneficial for human health. Saffron cultivation commonly occurs in open field, and spice yield can vary greatly, from 0.15 to 1.5 g m−2, based on several agronomic and climatic factors. In this study, we evaluated saffron cultivation in soilless systems, where plants can benefit from a wealth of nutrients without competition with pathogens or stresses related to nutrient-soil interaction. In addition, as plant nutrient and water uptake can be enhanced by the symbiosis with arbuscular mycorrhizal fungi (AMF), we also tested two inocula: a single species (Rhizophagus intraradices) or a mixture of R. intraradices and Funneliformis mosseae. After one cultivation cycle, we evaluated the spice yield, quality (ISO category), antioxidant activity, and bioactive compound contents of saffron produced in soilless systems and the effect of the applied AMF inocula. Spice yield in soilless systems (0.55 g m−2) was on average with that produced in open field, while presented a superior content of several health-promoting compounds, such as polyphenols, anthocyanins, vitamin C, and elevated antioxidant activity. The AMF symbiosis with saffron roots was verified by light and transmission electron microscopy. Inoculated corms showed larger replacement corms (+50% ca.). Corms inoculated with R. intraradices performed better than those inoculated with the mix in terms of spice quality (+90% ca.) and antioxidant activity (+88% ca.). Conversely, the mixture of R. intraradices and F. mosseae increased the polyphenol content (+343% ca.). Thus, soilless systems appeared as an effective alternative cultivation strategy for the production of high quality saffron. Further benefits can be obtained by the application of targeted AMF-based biostimulants.

Abstract Background: Soil salinity is an important problem for agriculture and effecting in the inability to use soil for cultivation. High salt levels reduce plant performance. Arbuscular mycorrhizal fungi (AMF) have been reported to enhance the tolerance of plants under salinity stress. For promote cultivation of economic plant in salt stress area that univariable to use to produce raw material for pulp industry. We determined the effects of AMF on the growth and nutrient status of eucalyptus (Eucalyptus camaldulensis Dehn.) seedlings under salinity stress condition.Results: Three different clones of Eucalyptus seedlings were pre-inoculated with three salt-tolerant AMF species, namely Glomus sp.2, Gigaspora albida and Gigaspora decipiens or without pre-inoculated. The seedlings were grown in a greenhouse for 45 days. They were then transplanted into individual pots, filled with field soil and subsequently treated with NaCl solution until the electro-conductivity (EC) reached 10, 15 and 20 dS m-1. They were watered for 90 days under nursery conditions. Increasing salinity levels reduced plant performance, fractional root colonization and the number of spores. Increasing salinity also resulted in a lower K/Na ratio. At the same time, performance of the pre-inoculated plants was significantly higher than that of plant that relied on field inoculum only. AMF also significantly increased chlorophyll and leaf proline concentrations and improved the K/Na balance.Conclusion: The results indicate that pre-inoculation with AMF before out planting improves plant performance under salinity stress due to AMF can improve the negative impacts of salinity on the studied physiological, nutrients uptake and biochemical parameters.
