“…Specifically, the highest mean transfer factor value of 4.33, 2.51 and 2.38 for 40 K, 232 Th and 226 Ra, respectively, was found in banana, maize and cowpea, respectively. TFs greater than 1 for 40 K (in range of 8.3–78.1 with mean of 42.2) have also been reported in some food crops grown in city of Ho Chi Minh, Vietnam [ 58 ]. Higher 40 K TF is used to imply plant survival strategy to subdue any serious environmental incidents [ 58 , 59 ].…”

“…However, the results derived from gamma analysis are not accurate due to radon release from the samples. On the other hand, the method is only performed with many environmental samples 5 . Our method using the analysis of alpha rays of 210 Po can resolve these problems.…”

Introduction: Soil-to-rice transfer factors (TF) are widely used to predict radionuclides' activity concentrations in rice plants. Since rice (Oryza sativa L.) is one of the most popular crops in Vietnam, the radiological risks due to 210Po contaminating rice grains and the TF must be concerned. Methods: Alpha spectrometry measured the activity concentration of 210Po in rice and soil samples collected in Chau Doc, An Giang province. TF for the uptake of 210Po from soil to rice plant has been calculated the ratio of the dry weight concentration in the plants to the dry weight concentration in the specified soil layer. Assessment of radiological risks due to ingestion of rice grains was based on estimation of the effective dose. Results: The activity concentrations of 210Po were in the ranges of 63.77 – 117.75 Bq kgdry weight-1 and 7.38 – 14.16 Bq kgdry weight-1 in soils and rice grains, respectively. Based on the radiation dose assessment, the accumulation of 210Po in rice grains was not considered for public health. The average TF values of 210Po were 0.12, 0.11, and 0.37 for grains, straws, and roots, respectively. Our TF values for rice were higher than the corresponding values found by other studies and the IAEA TRS-472 report. Conclusion: The analytical method for 210Po determination using alpha spectrometry can be applied for further studies in the field of environmental radioactivity. The measured TF values can be used to predict the radioactivity level of 210Po in rice plants cultivated in other fields in the Mekong Delta region.

“…Regarding the mineral content of leaves (Table 3), rst of all, the nutrient levels in plant tissues of the plant vary over time, depending on the growth stage of the plant and the part analysed (Hu et al 2023). Citrus trees change mineral nutrient absorption during growth and development processes (Bui et al 2020). Therefore, increasing root zone temperature, affects water and nutrient uptake by accelerating metabolic activity (Lee et al 2005) and promoting increased root volume and absorption area (Hussain and Maqsood 2011).…”

Aims The lemon cultivation methods and techniques are crucial to ensure maximum productivity in the face of climate change. Mulching with plastic is commonly used in citrus production for saving water, but some side effects need to be investigated. In our study, we investigated different plastic and biological mulching on lemon trees determining growth and physiological parameters in relation to soil chemical and biological composition. Methods The experiment was divided into four different lines with ten trees per treatment, the effect of mulching with white and black plastic film, dry pruning mulching respect to a non-mulched treatment of lemon tree orchard during a crop season. The impact of these treatments on vegetative growth, stomatal gas exchange and mineral nutrition on plant and soil bacterial communities were evaluated. Results Our results showed that the type of mulching significantly influenced in the parameters studied. All mulching treatments increased temperature and soil moisture levels; plastic mulching treatments had significantly higher values in terms of intrinsic water use efficiency; while mulching with dry pruning showed higher microbial activity and higher soil nutrient concentration, leading to increased water use efficiency and productivity. Conclusion The results showed that different methods of mulching affected the physiology of lemon trees interacting in a complex way to determine their growth. Specifically, mulching using dry pruning improved the exchange of gases in the plant and plant nutrition which was related to the biological soil health.
