“…In general, zinc is more rapidly released from the roots to the shoot than cadmium and is also then more easily redistributed within the shoot via the phloem [18,20]. The redistribution of a heavy metal may additionally be affected by environmental conditions, such as drought [21], light intensity [22], or nitrogen source [23,24], as well as by the availability of other heavy metals [25]. Cadmium and zinc contents are often both increased in polluted soils [26,27].…”

“…In contrast to wheat, dwarf bean, or lupin, cadmium and zinc are rapidly transferred from the roots to the aerial plant parts of the hyperaccumulator S. nigrum [4,8,18,20]. Bean was extremely inefficient in the transfer of cadmium from the medium to the shoot, regardless of the cadmium concentration in the medium, while wheat was only slightly more efficient [25]. In wheat and bean, the zinc transfer to the shoot was somewhat better than for cadmium, but it was still far less efficient than in S. nigrum [25].…”

In wheat and bean, the zinc transfer to the shoot was somewhat better than for cadmium, but it was still far less efficient than in S. nigrum [25]. For the study reported here, the relative mobilities of the often co-occurring elements cadmium and zinc and possible interferences in the transport of the two elements are particularly interesting.…”

“…It appears likely that xylem loading in the roots is a key process for rapid transport via the transpiration stream from the root system to the leaves [4,19]. Increased cadmium or zinc levels in the root medium only caused rather modest effects on the transport of 109 Cd and 65 Zn in bean and wheat [25]. Since S. nigrum differs considerably from wheat and bean in the accumulation and transport of cadmium and zinc on the whole plant level, the results obtained with the two crop plants mentioned cannot be simply transferred to this hyperaccumulator [8,18,20].…”

“…The aim of the work reported here was to identify the influence of an increased zinc or cadmium supply on the dynamics of these elements, with special reference to interactions between cadmium and zinc translocation in the hyperaccumulator S. nigrum . The radionuclides 109 Cd and 65 Zn allow sensitive and simultaneous detection in various plant parts with gamma spectrometry [8,15,16,18,20,21,22,25]. Besides the root-to-shoot transfer, the redistribution within the shoot from older leaves to younger leaves and finally to flowers/fruits can be addressed with the technique used.…”

Heavy metal redistribution is relevant for the quality of edible crops and the suitability of hyperaccumulators for bioremediation. Root-to-shoot transfer via the xylem and redistribution in the aerial parts via the phloem differ between various heavy metals. In general, cadmium is more slowly released to the shoot than zinc (e.g., in wheat, bean, and lupin). However, rapid cadmium transport to the shoot was detected in the hyperaccumulator Solanum nigrum L. This is a key aspect in this article and might be important for bioremediation. The radionuclides 109Cd and 65Zn were used to investigate the respective influence of elevated cadmium or zinc in the root medium on the dynamics of the two heavy metals in S. nigrum. Although transport via the xylem to the leaves was similar for 109Cd and 65Zn, the further redistribution from older leaves to younger leaves, flowers, and fruits via the phloem was far less efficient for 109Cd than for 65Zn. Furthermore, the redistribution of 109Cd within the shoot was negatively influenced by increased cadmium (but not by increased zinc) concentrations in the nutrient medium. The redistribution of 65Zn in the shoot was selectively decreased by increased zinc concentrations (but generally not by cadmium).

The characterization of the thermophysical properties of new environmentally friendly fluids, such as hydrofluoroether fluids (HFEs) and their mixtures with other compounds, is necessary nowadays in order to properly design the machinery and piping networks involved in their utilization. However, scarce data concerning these kinds of fluids are actually available. In this work, new experimental high pressure density data (742 points) for the binary system x HFE-7100 + (1 − x) 1-propanol are presented. This property was measured by using an Anton Paar vibrating tube densitometer in the temperature range of 298.15−393.15 K and in the pressure interval of 0.1−70 MPa. A comparison between our experimental high pressure density data and those found in the literature was carried out only for the pure compounds, since no density data for the binary mixture were found. To perform this comparison, we used a Tait-like equation in order to correlate our results to those of the literature. Concerning the experimental density data, the derivative properties of isothermal compressibility, κ T , and isobaric expansion, α P , were determined over the same pressure and temperature ranges. Excess molar volumes of the binary system were also determined and compared with those of the mixture x HFE-7100 + (1 − x) 2-propanol published in one of our previous works.

The effect of soil and climatic conditions on the distribution of nutrients in Actinidia arguta leaves

et al. 2020

The patterns of the distribution of nutrients in kiwiberry (Actinidia arguta (Siebold & Zucc.) Planch. ex Miq.), family Actinidiaceae (Gilg & Werderm), leaves growing under different soil and climatic conditions (Ukraine and China) were studied. Using scanning electron microscopy, significant differences were shown in the distribution of assimilates and mineral nutrients in the leaves of kiwiberry cultivated under different climate and soil conditions (Kyiv city, Ukraine and Jiamusi, China). The leaves of plants grown in China have higher concentration of all of the studied nutrients exception for silicon. The differences found in the content of macro- and microelements in plant tissues are consistent with their total content in the soil, and depend on the synthesis of low molecular weight organic compounds, namely, hydroxybenzoic, benzoic and triterpene acids. An increase in the silicon content in the leaves of kiwiberry plants grown in Ukraine indicates the moisture deficit in the soil. This conclusion is confirmed by the anatomical differences viz. the presence of additional integumentary formations and fewer stomata number per 1 mm2 of leaf surface. The specific feature of ‘Perlyna sadu’ cultivar was high concentrations of sodium and aluminum in the foliar tissues, regardless of the place of growth. The analysis of the distribution of nutrients in the leaves located along the stem showed remobilization of the former within the three layers: the lower one nourishes the roots, the upper one nourishes the leaves in the active growth phase and the middle one allocates the assimilates in both directions. A significant positive relationship was found between the biosynthesis of photosynthetic pigments and electrophysiological activity, especially for the leaves of the lower zone. The revealed differentiation into layers differing in polarity of bioelectric potentials and the distribution of assimilates suggests functional differentiation of the kiwiberry leaves. In particular, the leaves of the lower layer perform a storage function. The middle part is less conservative and characterized by higher sensitivity to environmental factors performs a mainly synthetic function. The upper layer performs an active growth function. The results of the comparative analysis of the indicators of the number of chloroplasts in the mesophyll cells proved that the obtained dependence can be used as a diagnostic criterion in assessing the predicted plant productivity at the early stages of their development.
