Background: Drought stress has become one of the biggest concerns in threating growth and yield carrots (Daucus carota L.). Recent studies have shed light on physiological molecular metabolisms response to drought carrot plant; however, tissue-specific responses regulations are still not fully understood. Methods: To answer this curiosity, study investigated interplay among tissues, such as leaves (L); storage roots (SRs); lateral (LRs) under conditions. This revealed that SRs played a...

Nitrogen (N) is one of crucial mineral nutrients for rice cultivation, however excessive N application has resulted in lower utilization and thus occasionally attributes to environmental impacts. Simultaneously, production requires greater watering, exacerbating water scarcity concerns. This study explores strategies enhance nitrogen use efficiency (NUE) rice, focusing on the carbon-nitrogen (CN) metabolism under different conditions. Two cultivars ( Oryza sativa L. cv. Samgwang-SG, NIL...

Abstract Xylem sap plays a major role in long‐distance transport of water, nutrients, and metabolites. However, there is little information on the behavior metabolites mineral‐deficient xylem sap. For this reason, time‐dependent changes selected (amino acids, organic soluble sugars) from tomato response to nitrogen (N), phosphorus (P), or potassium (K)‐deficient condition were investigated. Tomato plants ( Solanum lycopersicum L.) grown hydroponically liquid culture under three different...

Analysis of mineral nutrients in plant is required for evaluating diagnosis nutritional status. Pretreatment procedure the analysis can be varied depending on elements to analyzed. Wet-digestion suitable total nitrogen, phosphate and cations, however, digestion solution including nitric acid not nitrogen analysis. Incineration analyze chloride, silicate sulfur. After digestion, analyzed by Kjeldahl method, detected at 470nm colorimetric with ammonium meta vanadate. Cations micro are...

Abstract Ammonium ions (NH 4 + ) are commonly found in contaminated water and a contributing factor to eutrophication. Carbonized rice husk, derived from various biomass sources, possesses porous structure, its characteristics influenced by the feedstock pyrolysis conditions. Hence, this study aimed investigate applicability of carbonized husk as an absorbent for NH removal. The adsorption kinetics were analyzed using Pseudo-first-order Pseudo-second-order models, while assessed Langmuir...
