Mineral Elements in Root of Wild Saposhnikovia divaricata and Its Rhizosphere Soil

Abstract

Mineral elements are important components of medicinal herbs, and their concentrations are affected by many factors. In this study, Ca, Mg, Na, K, Fe, Mn, Cu, and Zn concentrations in wild Saposhnikovia divaricata and its rhizosphere soil collected from seven locations at two different times in China were measured, and influences of rhizosphere soil on those minerals in plant were evaluated. The results showed that mean concentrations of eight minerals in plant samples decreased in the order: Ca > Mg > Na > K > Fe > Zn > Mn > Cu, and those in the soil samples followed the following order: Na > Fe > Ca > K > Mg > Mn > Zn > Cu. Mean concentrations of Ca, Na, Mg, and K in plants were higher than those in soils, while higher mean concentrations of the other four minerals were found in soils. It was found that there was a positive correlation of Mg, Na, and Cu concentrations in the plant with those in the soil respectively, but a negative correlation of Mn concentration in plant with that in the soil. Except Ca, K, and Mn, the other five minerals in plant were all directly affected by one or more chemical compositions of soil. The results also indicate that pH value and concentrations of total nitrogen, Mg, Mn, and Cu in soil had significant correlations with multimineral elements in plant. In a word, mineral elements uptake of S. divaricata can be changed by adjusting the soil fertility levels to meet the need of appropriate quality control of S. divaricata.

Concentration of fifteen elements in herbaceous stems of Ephedra intermedia and influence of its growing soil

“…The uptake of mineral nutrients in a plant was controlled by soil characterisations and plant biological properties 20 . CAs between herb elemental concentrations, and soil characterisation factors demonstrated that humus, CEC and sand were more important than other characterisation factors in the soils (Table 2 ).…”

“…Therefore, N, P, K, Cu and Mo in E. intermedia were easily influenced by elements in the soils, and Fe, Mn and Zn in the soils were important for E. intermedia. The uptake of mineral nutrients in a plant was controlled by soil characterisations and plant biological properties 20 . CAs between herb elemental concentrations, and soil characterisation factors demonstrated that humus, CEC and sand were more important than other characterisation factors in the soils (Table 2).…”

“…Mineral nutrients, mainly originating in soil, are absorbed by plants from soil solution in some form of inorganic ions or acids 20 . Soil type and composition influence the physiological processes of mineral nutrient adsorption, distribution and accumulation of plants 20 – 23 .…”

“…Mineral nutrients, mainly originating in soil, are absorbed by plants from soil solution in some form of inorganic ions or acids 20 . Soil type and composition influence the physiological processes of mineral nutrient adsorption, distribution and accumulation of plants 20 – 23 . Numerous researchers have proven that cation exchange capacity (CEC), pH, organic matter and carbonate concentrations of soils could affect absorption and bioavailability of elements 24 – 26 .…”

Leaf-associated bacterial microbiota of coffee and its correlation with manganese and calcium levels on leaves

“…Leaves are sources of mineral nutrients throughout plant development, especially during vegetative growth ( Maillard et al , 2015 ). Bacterial communities and mineral nutrients were correlated on rhizosphere ( Lepleux et al , 2013 ; Sun et al , 2013 ). However, correlation between mineral nutrients and phyllosphere microbiome deserves further studies.…”
