Toxics, Journal Year: 2025, Volume and Issue: 13(1), P. 56 - 56

Published: Jan. 14, 2025

Rice, wheat, and maize grains are staple foods, widely consumed for their mineral nutritional values. However, they can accumulate toxic elements from contaminated soils, posing health risks. This study investigates the bioaccumulation patterns of 52 (including nutrients, heavy metals, rare earth elements) in various parts (grain, husk, straw, root) cereals grown a heavily polluted region. The results revealed that rice exhibited higher accumulation (Σ33.4 mg/kg) (As, Cu, Cr, Ni, Pb) than wheat (Σ26.6 (Σ16.2 grains, with high-yield RI64 cultivar (Σ47.0 being most susceptible. Across plant, increased order grain < husk straw root. Elements like P, K, Zn showed highest enrichment. Worryingly, elements, such as As, Pb, Cd, exceeded permissible limits across straws, husks. Health risk assessment indicated pose greater non-cancer cancer risks rice. Despite highly region, identifies some cultivars Luchai Sarna relatively safer options due to lower elements.

Synergistic Effects of Mineralization Degree and Sodium Adsorption Ratio on the Rhizosphere Bacterial Community and Soil Nutrients of Upland Cotton Under Saline Water Irrigation

Agronomy, Journal Year: 2025, Volume and Issue: 15(4), P. 895 - 895

Published: April 3, 2025

In global drought-prone cotton-growing (Gossypium hirsutum L.) areas, saline water irrigation has become a key strategy to alleviate the shortage of freshwater resources. Against this backdrop, synergistic effect mineralization degree (MD) and sodium adsorption ratio (SAR) on rhizosphere microecological regulation mechanism remains unclear. To address issue, study constructed an experimental framework interaction between MD SAR, aiming explore their effects bacterial community structure in cotton soil environment. The type area is saline–sodic sandy loam. design, three levels (3 g/L, 5 7 g/L) were set, under each condition, SAR (10 (mmol/L)1/2, 15 20 (mmol/L)1/2) arranged. addition, local was used as control group (CG), resulting total 10 treatment schemes. aim investigate varying communities results indicated that could enhance diversity richness alter its structure. Under with 3 g/L reached peak levels. Compared CG, Chao1 index significantly increased by 260 units, while Shannon 0.464.

Metabolic Profile Changes and Early Detection of Nitrogen Deficiency in Sweet Corn

Agriculture, Journal Year: 2025, Volume and Issue: 15(8), P. 856 - 856

Published: April 15, 2025

In this study, we investigate the nutrient supply of young corn (Zea mays var. rugosa) plants using conventional biological and chemical methods, as well N-glycan metabolic profile plant sap MALDI-MS. Corn with three different supplies were grown on sandy soil for 45 days after emergence. treatment 1 (T1), used a control, did not receive any supplementation. Plants in 2 (T2) received “ideal” N-, P-, K-nutrient supplementation form inorganic fertilizers. 3 (T3), provided ideal amount P K, reduced N fertilizer. addition to biomass plants, macronutrient content (N, P, Ca, Mg) was measured dry matter. We examined 0.01 M CaCl2-soluble fractions experimental soils, Mg their ammonium lactate (AL)-soluble fractions. unable statistically distinguish between T1, T2, T3 treatments methods (in phenophase). Metabolic profiles from captured by MALDI-MS, showed significant differences “ideal”, N-deficient treatments. This method may also be suitable early detection conditions other plants.
