Mineral Nutrition of Higher Plants
Introduction, definition, and classification of mineral nutrients. Ion uptake mechanisms of individual cells and roots: short distance transport. Long-distance transport in the xylem and phloem and its regulation. Uptake and release of mineral elements by leaves and other aerial plant parts. Yield and the source-sink relationships. Mineral nutrition and yield response. Nitrogen fixation. Functions of mineral nutrients: macronutrients. Functions of mineral nutrients: micronutrients. Beneficial mineral elements. Relationships between mineral nutrition and plant diseases and pests. Diagnosis of deficiency and toxicity of mineral nutrients. Plant-soil relationships. Nutrient availability in soils. Effect of internal and external factors on root growth and development. The soil-root interface (Rhizosphere) in relation to mineral nutrition. Adaptation of plants to adverse chemical soil conditions.
