“…Conversely, ABA is a hormone that primarily regulates the maize plant’s response to stress and adversity and inhibits maize growth. The inhibitory impact of ABA on maize growth is mitigated through the reduction in synthesis and accumulation of ABA due to the availability of Ca and Mg ( Piao, 2020 ). This implies that Ca and Mg exert a beneficial influence on the control of maize development and growth.…”

“…This phenomenon occurs due to the interaction between the positively charged residues in the enzyme and the negatively charged Ca 2+ and Mg 2+ . This interaction facilitates the formation of the active site and enhances the stability of the enzyme’s steric structure ( Piao, 2020 ). Furthermore, the catalytic efficiency of the enzyme can be enhanced by regulating the substrate binding and release processes with the assistance of Ca and Mg ( Rosanoff and Kumssa, 2020 ).…”

“…(2) Single-factor randomized block design was used as the experimental design. Using the reference threshold of deficiency supplementation and the deficit and surplus criteria of maize demand for Ca and Mg, three Ca levels (none: 0.00kg hm -2 , low: 17.50kg hm -2 , high: 49.00kg hm -2 ) and three Mg levels (none: 0.00kg hm -2 , low: 24.50kg hm -2 , high: 35.00kg hm -2 ) were designed for the entire reproductive period of maize ( Piao, 2020 ). For a total of 15 trial samples, five treatments with varying Ca and Mg levels were established and duplicated three times each.…”

The content of kernel starch (STC), which is a fundamental indicator of the nutritional value of maize, is directly correlated with the grain’s taste and aroma. Both calcium (Ca) and magnesium (Mg) are critical nutrients that play a significant role in the growth and development of maize, as well as in the synthesis of STC. To determine the physiological driving mechanisms of Ca and Mg effects on the accumulation of STC synthesis in maize kernels and the characteristics of their effects on endogenous hormones and enzymes of STC synthesis in maize leaves, our study applied foliar Ca and Mg fertilizers at various levels to maize prior to pollination. (1) The levels of Ca, Mg, indole-3-acetic acid (IAA), gibberellin (GA), and zeatin riboside (ZR) in maize leaves increased and then decreased after the supplementation of Ca and Mg. They peaked on the 32nd day after pollination. In contrast, the levels of abscisic acid (ABA) initially decreased and then increased. Ca and Mg had a negative correlation with ABA and a positive correlation with IAA, GA, and ZR. (2) As the levels of Ca and Mg increased, correspondingly rose the activities of enzymes responsible for STC synthesis and the content of STC and its components. Principally influencing the synthesis of STC were ABA, IAA, uridine diphosphate-glucose pyrophosphorylase (UDPG), granule-bound starch synthase (GBSS), and soluble starch synthase (SSS). (3) “IAA–UDPG or GBSS–STC” was the predominant physiological regulation pathway of Ca on kernel STC, whereas “IAA–GBSS–STC” was the dominant physiological regulation pathway of Mg on kernel STC. The regulatory impact of STC by UDPG and GBSS was positive, as were the effects of IAA on UDPG and GBSS. In conclusion, the accumulation of kernel starch was significantly enhanced by Ca and Mg supplementation via the modulation of endogenous hormone levels and key enzyme activities. This research identifies a viable approach to improve the nutritional composition of maize.

“…In recent years, declining crop yields and quality because of plant Mg deficiency in crops grown on soils considered to be rich in Mg (Farhat et al, 2016; Guo et al, 2016; Yan et al, 2016). Soil Mg availability and plant uptake of Mg are hindered by the high concentration of other cations, such as potassium (K + ), calcium (Ca 2+ ) and manganese (Mn 2+ ) (Li et al, 2018; Piao, 2020; Rhodes et al, 2018). When soil Ca 2+ , K + and Mn 2+ content increases, soil Mg 2+ availability is significantly inhibited because of the competition between cytoplasmic cations (Li et al, 2018).…”

Magnesium (Mg) deficiency in greenhouse vegetable plants affects crop yields and quality. Assessing the degree of Mg deficiency and influencing factors is necessary for evidence‐based Mg supplementation. In this study, an investigation was conducted at 71 tomato cultivation greenhouses with calcareous soil, located in the main greenhouse vegetable production area of China. Plant and soil Mg contents were analysed, as well as nitrogen (N), phosphorus (P), potassium (K) and other nutrients. The tomatoes showed Mg deficiency, with none of the farms supplementing this element. The critical leaf Mg concentration of the tomatoes was 3.40 mg kg−1. Using Ward's hierarchical cluster analysis, three clusters of Mg leaf content were obtained, which were 1.07–3.00 mg kg−1 (SD cluster), 2.56–5.64 mg kg−1 (MD cluster) and 5.12–6.88 mg kg−1 (ND cluster). Tomato yields in the SD and MD clusters were 31.4% and 16.5% lower than the ND cluster, respectively. Both soil exchangeable Mg content and soil pH in the SD cluster were the lowest, while total NPK, available NPK, K/Mg and the Ca/Mg ratio were the highest. A principal component analysis (PCA) showed that Mg leaf content was negatively correlated with the exchangeable K/Mg ratio, and positively correlated with soil exchangeable Mg content, soil pH and tomato yield. Mg deficiency in the tomatoes was attributed to the high accumulation of available K in the calcareous soil and the fact that the SD cluster with greatest Mg deficiency also had the lowest soil total Mg concentration. Considering the accumulation of NPK and the causes of Mg deficiency, foliar Mg spraying is suggested to mitigate Mg deficiency in calcareous greenhouse tomato soil.
