The Macroelements. Calcium (Ca): Calcium functions as a cofactor with many enzymes and is particularly important in cell well synthesis. Calcium deficiency may result in shoot tip necrosis. Calcium used in plant tissue culture is mostly in the forms of calcium chloride and calcium nitrate in a concentration of 1-3 mM.
The plant tissue culture medium with ideal pH has been prepared from the stocks of microelements, macroelements, and PGRs having the desired concentrations of carbon source and gelling agent. A sample setup of the chemicals required for the plant tissue culture media preparation is shown in Fig. 1.
Special Issue Information. Dear Colleagues, Microelements are essential for the healthy growth of higher plants, and also required by crops for high yield and quality. If one or more of these elements is deficient, crops will fail to achieve their optimum yield, and the quality of their food products is likely to be impaired.
Cu, Fe, Mn, and Zn concentrations significantly increased with grazing intensity. In soil, macroelement dynamics (i.e., C, N, and P) exhibited higher sensitivity with graz - ing intensity, conversely in plants, microelements were more sensitive. This result indicates macroelements and microelements in soil and plants had asymmetric re-

To evaluate the effectiveness of a plant to accumulate macro- and microelements, the Biological Concentration Factor (BCF) was used (Solgi et al. 2020). BCF was calculated as the ratio of macro- and microelement concentrations in the needles versus soil: ... The mean macroelements concentrations found in the soil and needles …
1. Introduction. All 14 essential elements including 6 macroelements and 8 microelements, are important for plant ontogenetic processes such as growth, maintenance and reproduction (Marschner, 2012; Luo et al., 2016).Although there are numerous studies on the variation in concentrations of both plant and soil …
Macronutrients: N, K, Ca, Mg, P, and S, and. Micronutrients: Cl, Fe, B, Mn, Zn, Cu, Mo, and Ni. The prefix "micro" is well-understood from its use in terms such as "microscope". The term "macro" is somewhat less common, but indicates objects of a somewhat large size. Intermediate sizes are sometimes indicated by "meso".
In soil, macroelement dynamics (i.e., C, N, and P) exhibited higher sensitivity with grazing intensity, conversely in plants, microelements were more sensitive. This …
Solution. Correct answer: Less than 0.1 mg/gm of dry matter. Microelements are the minerals which occur in plants in very small amounts. Their concentration in plants is equal to or less than 0.1 mg/gm of dry matter. They are also called micronutrients. Fe, Zn, Mn, B, Cu, Mo, Cl and Ni are eight microelements.
in concentrations of both plant and soil macroelements and on their impacts on plant growth and functions ( Delgado-Baquerizo et al., 2013 ; Jiao et al., 2016 ; Li et al., 2022 ), little is known ...
We determined leaf microelement BCFs by measuring the concentrations of Mn, Fe, Ni, Cu and Zn in soils from 33 sites and leaves of 111 plants from 67 species across the drylands of China. Leaf...
Plants are generally much less tolerant of high levels of microelements than they are of macroelements. For example, the amount of potassium in ... show marked reactions, whereas with the microelement boron, defi ciency can occur below 0.5 mg 1-1 and toxicity at concentrations above 3 mg 1-1; copper, ... the availability of the microelements ...
For three plant functional groups, the concentrations of macroelements (N, P, K, and Ca) and essential microelements (Fe and Zn) were higher at the P-rich …

Mean plant leaf mineral elements concentrations in China were from Han et al. (2011) (Supplementary Table 5). Soil TOC, N, P, C/N, ... Our study not only investigated the variability of macroelements and microelements, but also investigated the variability of heavy metals. According to the hypothesis inference, the variability of heavy metals ...
This result indicates macroelements and microelements in soil and plants had asymmetric responses with grazing intensity. The slopes of nutrient linear regression in C. squarrosa were higher than that of S. krylovii and L. chinensis, indicating that C. squarrosa had higher nutrient acquisition capacity and responded more rapidly to heavy grazing.
common concentrations of macroelements, K and Mn, are in correlation with concentrations of microelements, Cd, Co, Ni and Zn. This indicates that the most of their concentrations in soils are ...
The concentrations of the microelements are expressed as molar mass per unit dry mass (mol/kg). Bioconcentration factor (BCF), the capacity of the plant to accumulate microelements in the leaf from soil (Pavel et al., 2014; Yang et al., 2015), was calculated as follows:

By analyzing the four macroelements contents of 41 plants in the evergreen broadleaf forest of Dinghushan, we found that the K, Ca, Na and Mg contents in the …
We collected 41 subtropical evergreen broadleaf plant leaves (31 tree species and 10 shrub species) during the wet and dry seasons, and determined contents of macroelements and microelements in ...
Information on the content of medicinal plants used in the treatment of diabetes is scarce in the literature. The objectives of this study were to determine the levels of macroelements and microelements in three different medicinal plant species including the dry samples and teas from Bauhinia forficata, Eleusine Indica, and Orthosiphon stamineus and …
