Photosynthetic parameters and growth of rice, lettuce, sunflower and tomato in an Entisol as affected by soil acidity and bioaccumulation of Ba, Cd, Cu, Ni and Zn

Abstract The bioaccumulation of trace elements (TEs) in crops consumed by humans can lead to a lower food production due to photosynthetic damages and several diseases in humans, but decreasing soil acidity could mitigate these problems by decreasing TEs bioavailability. Thus, we evaluate the effect of increasing soil base saturation (BS%) on photosynthesis, growth and bioaccumulation of barium (Ba), cadmium (Cd), copper (Cu), nickel (Ni) or zinc (Zn) in lettuce (Lactuca sativa L.), rice (Oryza sativa L.), sunflower (Helianthus annuus L.) and tomato (Solanum lycopersicum L.) grown in sandy Entisol. The crops were grown in uncontaminated or contaminated Entisol, under two BS% ratios: 30% for all crops or 50% for rice and 70% for lettuce, sunflower and tomato. The photosynthesis-related parameters varied depending on the metal and crop, but in general, increasing BS% did not attenuate photosynthetic damages induced by Ba, Cd, Cu, Ni and Zn in the crops. There was no strong correlation between the photosynthetic parameters measured and biomass production, which suggest us that the suppression on biomass induced by Ba, Cd, Cu, Ni or Zn is related to other metabolic disorders besides the impairment on CO2 assimilation or chlorophyll synthesis in the crops assayed, with exception of Ni and Zn in lettuce. In conclusion, increasing BS% was not consistent in decreasing Ba, Cd, Cu, Ni and Zn accumulation in the edible parts of lettuce, rice, sunflower and tomato grown in the sandy soil, which probably is related to the low capacity of this soil in control TEs bioavailability.

AbstractThis paper brings out the results of the study on the levels of selected trace elements (Cu, Fe, Mn, Zn and Cr) in aerial parts of Thymus pannonicus All. (Lamiaceae) and rhizosphere soil from twelve locations in Serbia. Prior to assays by flame and flameless atomic absorption spectrometry, samples were subjected to microwave-assisted acid digestion. Real and potential acidity of soil samples were also measured. Obtained results for soil samples, although slightly higher for some elements (Cu: 12.38–45.18 mg/kg; Fe: 22102–46193 mg/kg; Mn: 776.95–4901.27 mg/kg; Zn: 62.27–214.02 mg/kg; Cr: 48.86–69.13 mg/kg), were found to fit into biogeochemical background. Element contents in plant samples differed depending on collecting site (Cu: 5.26–14.07 mg/kg; Fe: 25.92–1454.07 mg/kg; Mn: 89.29–278.25 mg/kg; Zn: 1.81–10.64 mg/kg; Cr: 1.11–3.51 mg/kg), which can be partly explainable by different nutrient availability influenced by soil acidity. Zinc levels in T. pannonicus were below expected and seem to be strongly influenced by plant physiological properties.

Main Factor

Trace elements are compounds that are essential in small amounts for biochemical reactions and to maintain human health. Almost all foods can contain varying amounts of these metals. In this study, the effects of food processing on the content of trace metals are investigated. Extensive interpretations of processing, including aspects of food production and specific examples of changes in metal content due to processing will be discussed. Pre-consumption food processing to improve rheological properties and increase shelf life is inevitable, which changes the bioavailability and amount of these compounds in different directions depending on the process. The amount of these trace metals in the food product can be affected by various conditions such as heating, fermentation, food additives, etc. The main factor in reducing trace elements in food, especially the use of heat in a special method and on the other hand, factors such as fermentation can also increase the bioavailability of these elements.

Edible Parts

The most important environmental source of boron (B) contamination is irrigation water. The data on the effect of B on the elemental composition in the edible parts of vegetables are scarce. A greenhouse pot experiment investigated the effect of irrigation water containing 0.1 and 0.5 mg/L B on the biomass, elemental (e.g., B, Mg, K, Fe, Cu, and Zn) composition, and photosynthetic parameters of tomato (Solanum lycopersicum), green bean (Phaseolus vulgaris), potato (Solanum tuberosum), and cabbage (Brassica oleracea) plants grown on 10 kg of sand, silty sand, or silty soil. The biomass of the edible part was unaffected by B treatment. The soil type determined the effect of B irrigation on the elemental composition of vegetables. The B content increased by 19% in tomatoes grown on silty soil. The 0.1 mg/L B treatment facilitated tomato fruit ripening on all soils, and the 0.5 mg/L B treatment doubled its chlorophyll content index (CCI) on silty soil. The 0.5 mg/L B treatment negatively affected the nutritional value of green beans on all soils, decreasing the Fe and K contents by an average of 83 and 34%, respectively. The elemental composition of potato was unaffected by the treatments, but the CCI of potato leaves increased in the 0.5 mg/L B treatment by 26%. The B content was increased by 39% in cabbages grown on light-textured soils. In conclusion, B concentration of up to 0.5 mg/L in irrigation water had no significant beneficial or adverse effect on the investigated vegetables, but 0.1 mg/L B treatment could shorten tomato fruit maturation time on B-poor soils. The B levels in vegetables remained suitable for human consumption.

And Diffusion

Problems concerning the emergence and geographical diffusion of food production in East Asia have long interested archaeologists and historians. However, attempts to reconstruct the chronology and diffusion routes from the so-called nuclear zones of both North and South China through the Korean peninsula and Japan have been less than convincing. In North China, the crops involved were millet (Setaria italica) and kaoliang (Sorghum vulgare); in South China, rice (Oryza sativa japonica and indica).
