Effects of salicylic acid on growth, mineral nutrition, glandular hairs distribution and essential oil composition in Salvia officinalis L. grown under copper stress

Effect of salicylic acid foliar application on growth, glandular hairs and essential oil yield in Salvia officinalis L. grown under zinc stress

“…These high concentrations caused a nutritional imbalance, which results in growth retardation [8,40]. Other researchers reported the same effect after accumulation of other metals such as copper [1,41,42] and cadmium [3,43]. In this perspective, our results showed that the mineral content in root and shoot was also significantly decreased by Zn stress.…”

“…Spraying of SA, particularly at 0.5 mM, increased the essential oil content in stressed plants. In stress condition, Khanam and Mohammad [70] on Mentha piperita L. and Es-sbihi et al [1] on S. officinalis L. showed also an increase in essential oil content under the effect of SA. These authors linked this increased in essential oil content under SA in stress condition, to the improvement of growth, photosynthesis, nutrient assimilation and peltate glands density.…”

“…The essential oil of S. officinalis presented high industrial and medicinal application. According to a previous study of Es-sbihi et al [1] and Hazzoumi et al [6], the main components of S. officinalis essential oils was cis-thujone, trans-thujone, camphor, 1,8-cineole. In the fruits of S. officinalis, Taarit et al [2] showed that viridiflorol, 1,8-cineole, thujone, camphor, borneol, caryophyllene, manool, thujone, pinene, linalool and caryophyllene oxide were the main compounds.…”

“…Under abiotic stress conditions, the remedial effect of SA on growth is linked to its role on the physiological parameters of the plant such as water content, nutrients assimilation, chlorophyll pigments biosynthesis, growth, regulation stomatal, inhibition of ethylene biosynthesis, regulation of hormonal profile and synthesis of protein kinase [23][24][25][26]. Our previous works [1] have shown the positive effect of SA on growth and on the accumulation of certain minerals (Ca, K and P) in S. officinalis grown under copper stress. Additionally, several studies showed that exogenous SA contributes to the regulation of the metabolic and physiological pathways of plants grown under heavy metals such as copper, cadmium, chromium and lead on plants [27][28][29][30][31].…”

Improving Vegetative Growth, Root Traits and some Chemical Constituents of Duranta erecta Var. Variegata by Using Humic Acid, Salicylic Acid and Chitosan تحسین النمو، وصفات الجذور وبعض المکونات الکیمیائیة للدورنتا المبرقشة باستخدام حمض الهیومیک وحمض السالیسیلیک والشیتوزان

“…There is a correlation between the beneficial effect of SA on the synthesis of secondary metabolites with advance in growth, photosynthesis and nutrient content (Khanam and Mohammad, 2018). These results also found by Es-sbihi et al (2020) who demonstrated that SA spraying on sage plants significantly increased plant growth. Furthermore, The positive influences of humic acid on cell membrane functions by elevating nutrient uptake, respiration, biosynthesis of ion absorption, nucleic acid, enzyme in order to they are hormone-like materials (Yang et al, 2004).…”
