Effect of phosphorus uptake on growth and secondary metabolites of garden sage (Salvia officinalis L.)

Abstract

BACKGROUND: Garden sage (Salvia officinalis L., Lamiaceae) has gained importance during the last decade as a natural antioxidant, mainly owing to the antioxidant secondary plant metabolites rosmarinic acid (RA) and diterpenes such as carnosic acid. The aim of this work was to study the biomass production, the concentrations of total phenolics and RA and the essential oil of garden sage in response to phosphorus (P) supply. The treatments included P fertilisation and inoculation with arbuscular mycorrhizal fungi (AMF), since AMF are the most efficient biotic factor promoting the P uptake of plants.

“…In our study, increased phenols content in stressed plants corroborate with the findings of Mehr et al (2012) for A. graveolens L., Tomar and Agarwal (2013) for wheat and Dawood et al (2014) for Vicia faba. In confirmation with our results, Nell et al (2009) also observed increased phenols content in AMF-inoculated Salvia officinalis L. plants as compared to uninoculated counterparts. Enhanced synthesis of phenols due to AMF inoculation under normal as well as stress conditions strongly supports the protective role of phenols in mitigating negative impact stressful environmental conditions.…”

Arbuscular mycorrhizal symbiosis and active ingredients of medicinal plants: current research status and prospectives

“…Kapoor et al (2004) obtained similar results for the accumulation of essential oil in fennel. Nell et al (2009) found that full phosphorus treatment leads to a 1.2-fold increase in total phenolic and rosmarinic acid concentrations in the leaves of S. officinalis, as compared with a half phosphorus treatment, AM fungal inoculation, or control plants, which suggests that secondary metabolite contents increase only when P is supplemented in a sufficient amount. However, the same authors (Nell et al 2010) observed either unchanged or significantly decreased contents of sequiterpenic acid in different genotypes of V. officinalis when plants were treated with P. Therefore, the effects of P on secondary metabolites may vary between different medicinal plants.…”

“…For example, inoculation with AM fungi results in an increase in anthocyanin content, but fails to alter the polyphenolic profile of leaves and stems of basil (O. basilicum) (Lee and Scagel 2009). Nell et al (2009) found that AM symbiosis has no effect on the total concentrations of phenolic and rosmarinic acid in the roots of Salvia officinalis, while Geneva et al (2010) reported an important decrease in total phenols and flavonoids contents of leaves in mycorrhizal S. officinalis.…”

Influence of light intensity on growth and physiological characteristics of common sage (Salvia officinalis L.)

“…(Bozin et al 2007). Recently, studies have been focused on the effect of some abiotic stress factors (just as water deficit (Bettaieb et al 2009;Corell et al 2009) or hydrogen (Ilkiu-Vidal et al 2010), salt (Taarit et al 2009) and phosphorus (Nell et al 2009) soil concentrations) on Salvia officinalis growth, productivity and secondary metabolites composition. S. officinalis is an economically interesting plant considering that together with Rosmarinus officinalis L. has the strongest antioxidant activities among the herbs (Santos-Gomes et al 2002).…”
