Investigation of Different Selenium Sources and Supplying Methods for Selenium Enrichment of Basil Vegetable (A Case Study under Calcareous and Non-calcareous Soil Systems).

Background: Selenium (Se) is a crucial component of selenoaminoacids and selenoproteins. Therefore, Se-enriched agricultural products can reduce health complications induced by Se deficiency.

Objective: This research was carried out to investigate the effects of Se bio-enrichment on Basil grown in calcareous and non-calcareous soil systems and also to evaluate the changes in Se concentration in the soil after harvesting.

Salt tolerance of a wild ecotype of vetiver grass (Vetiveria zizanioides L.) in southern China.

Background: Vetiver grass (Vetiveria zizanioides L.) is widely used in more than 120 countries for land management (e.g.

Wheat responses to sodium vary with potassium use efficiency of cultivars.

The role of varied sodium (Na) supply in K nutrition of wheat (Triticum aestivum L.) is not well understood especially among cultivars differing in K efficiency. We examined the response of K-efficient and K-inefficient Australian wheat cultivars to Na supply (low to high Na) under K-deficient and K-adequate conditions.

Cd uptake in rice cultivars treated with organic acids and EDTA.

A pot experiment was conducted to examine the activity of antioxidant enzymes, the content of malondialdehyde (MDA), proline and protein, and Cd uptake in different rice cultivars exposed to Cd (0, 1 and 5 mg/kg) in the presence of organic acids and ethylenediamine tetraacetic acid (EDTA). The results showed the increase in activity of dismutase (SOD), contents of proline and protein but a decline in activities of peroxidase (POD) and catalase (CAT), and MDA content for cultivars Xiushui63 and IIyou527. The resistance to Cd was higher in Xiushui63 than that in Iyou527 under the same Cd treatment.

Changes in soil-plant P under heterogeneous P supply influence C allocation between the shoot and roots.

Wheat plants (Triticum aestivum L.) were subjected to varying phosphorus (P) supply and canopy CO feeding to uncouple the plant and soil factors regulating carbon (C) allocation between the shoot and roots and in the P-enriched v. P-deficient soil zone.

Aluminium toxicity in rye (Secale cereale): root growth and dynamics of cytoplasmic Ca2+ in intact root tips.

Aluminium (Al) toxicity in rye (Secale cereale L.), an Al-resistant crop, was examined by measuring root elongation and cytoplasmic free activity of calcium ([Ca2+]cyt) in intact root apical cells. Measurement of [Ca2+]cyt, was achieved by loading a Ca2+-sensitive fluorescent probe.

Soil salinity modifies SO sensitivity in soybean.

Soybean (Glycine max L. cv. Buchanan) growing in top-covered chambers was exposed to a factorial combination of three concentrations of SO , (2, 99 and 189 nl1 ) and three concentrations of soil salinity with electrical conductivities of 0.
