“…The efficiency of foliar application of fertilisers can also be a function of the environmental factors (temperature, light intensity and relative humidity) and plant structure (the presence of waxes, cuticle thickness and composition). These environmental and plant factors can also interact to increase or decrease the foliar fertilisation efficiency (Bonomelli et al, 2021).…”

The green bean (Phaseolus vulgaris L.) is a very widely grown food crop that contributes significantly to human dietary needs in many countries due to its high content of protein. This study evaluates foliar applications of ZnSO4 versus that of zinc oxide nanoparticles (ZnO NPs) to leaves of the green bean cv. ‘Strike’ and records the plant responses in terms of Zn uptake and concentrations of photosynthetic pigments and bioactive compounds. The experiment was conducted under greenhouse conditions in Chihuahua, Mexico, with a completely randomised experimental design with 10 replicates. The two treatments were foliar applications of either an aqueous solution of ZnSO4 or an aqueous suspension of ZnO NPs (both 150 mg · L−1). The application of ZnO NPs significantly increased concentrations of Zn2+ in the leaflets, roots, stems and pods of chlorophylls a and b (values 15.40 μg · g−1 and 11.64 μg · g−1, respectively). Sucrose concentration was also increased by Zn2+ applications, but no differences were found in total phenols (TP), total flavonoids (TFl) or antioxidant capacity (AC). In the pods and seeds, Zn2+ application left sucrose and TFl concentrations unchanged, but the TP increase was significant. The AC was affected by both zinc sources and only in the pods. The applications of ZnSO4 or ZnO NPs significantly increased the biomass accumulation (79.10 g · p−1 and 84.70 g · p−1 DW) and yield (55.64 g · p−1 and 53.80 g · p−1 FW). These results suggest that the application of ZnO NPs could represent a worthwhile biofortification strategy in the commercial production of green bean cv. ‘Strike’.

“…Calcium accumulation may occur in organs with high transpiration. Low transpiration rates can ensure plants well hydrated, which is bene cial to absorb the extra calcium [32]. Therefore, Camellia limonia can adapt better to the high calcium karst environment under a certain transpiration intensity.…”

Background: Yellow Camellia is a kind of rare plant with high economic and medicinal value. It is known as the "giant panda" of the botanical world. Camellia group of plants (Camellia Sect. Chrysantha Chang) is the only golden flower of Theaceae. Compared with Camellia nitidissima, Camellia limonia grows in karst areas, where the soil has the characteristic of high calcium content. However, there are few studies about the Camellia limonia in karst soil environment and the adaptation mechanism is no clear. Results: In this study, we found that under high calcium treatment, the chlorophyll content and leaf areas of Camellia limonia increased, while those of Camellia nitidissima decreased. The photosynthetic efficiency of Camellia limonia was more stable and higher than Camellia nitidissima. Compared with Camellia nitidissima, the conductance was larger and the degree of leaf shrinkage was smaller in Camellia limonia. The metabolomics analysis showed that the kaempferol-3-o-rutinoside, tyrosol, 6-o-methyldeacetylisoipecoside and (r)-mandelic acid are the main differently metabolic compounds . The results of karst high calcium soil metagenomics showed that microbacterium-testaceum, intrasporangium-calvum and rubrivivax-gelatinosus significantly changed. Through metabonomics and metagenomics integrative analysis, flavone and flavonol biosynthesis is suggested to be the main regulation pathway, which is regulated by apigenin, kaempferol, astragalin, isoquercitrin metabolites and TT7, UGT78D1, UGT78D2 genes. This metabolic pathway involves the synthesis of flavonoids. Flavonoids have the functions in drought and salt resistance, which play an important role in the adaptation of Camellia limonia in karst high calcium environment.Conclusion: This omics study identified key regulation metabolites and genes for Camellia and provided important basis for the adaptive mechanism of plants to adapt to the high-calcium environment and the protection of Camellia species.

“…Very little calcium ( 45 Ca) was transported from the treatment site to neighboring tissues when a calcium chloride ( 45 CaCl2) solution was sprayed onto the basal and apical leaves of chili pepper. The direct application of repeated calcium spray doses to growing fruiting organs may therefore be the most efficient calcium fertilization technique for raising chili fruit calcium concentrations [14].…”

The chlorophyll content and mineral compositions of plants are highly dependent on the species' physiological responses and environmental stress tolerance. The chlorophyll content is important for determining abiotic stress tolerance in tomatoes and peppers. Several studies found that foliar applications of specific components increased tomato and pepper output by increasing nutrient uptake. After transferring the seedlings to the incubator, three tomatoes (Mobil, Korall, and Tyking F1) and three pepper varieties (Carma, Fokusz, and Bobita F1) were sprayed. The following solutions were applied at a rate of 4 mL to each different plant: sodium bicarbonate (0.52%), 50 mg L-1 salicylic acid, and distilled water. A chlorophyll sensor (SPAD-502) was used to collect 5 measurements from each plant after 2 days and 8 days of spraying. Five plant sap samples were collected from ten plants after 38 days of transplantation. The calcium ion (Ca+2), potassium ion (K+), and nitrate (NO3-) contents (mg L-1) in plant sap were measured using three calibrated electronic sensors of the type (HORIBA instruments LAQUA-TWIN). The factorial analysis of two factors was used in data collection and statistical analysis. The first variable was the variety and the second was the spray treatment, and each record had five observations. The Tukey-Kramer test in Minitab 20 was used to assess differences in means between groups. Minitab 20's regression response optimizer was used to determine the maximum and minimum responses to calcium, potassium, nitrate, and chlorophyll content factors in each plant. Salicylic acid 50 mg L-1 produces the strongest multiple responses, particularly in tomato cultivars (Tyking F1 and Korall). The multiple minimum responses were for the variety (Mobil). Spraying (Mobil) with salicylic acid (50 mg L-1) and sodium bicarbonate (0.52%) produced unsatisfactory results. Salicylic acid 50 mg L-1 elicits also the most powerful multiple responses, particularly in the (Carma) pepper cultivar. The results revealed multiple minimum responses for the variety (Bobita F1). Finally, it is recommended that growers grow tomatoes (Mobil) without any supportive spraying treatment because the vigor of tomato (Mobil) seedlings was significantly higher in suboptimal environmental conditions. Gardeners should consider growing (Carma) pepper with a supportive spraying application of salicylic acid 50 mg L-1.
