After reading this article you will learn about the pathway of solutes from the external solution into the plant cells. Movement of low molecular weight solutes (e.g. ions, organic acids, amino acids, sugars) from the external solution into the cell walls of individual cells or roots (free space) is a non-metabolic, passive process, driven by diffusion or mass flow. Nevertheless, [...]
After reading this article you will learn about the passive and active transport of ions from the epidermis to xylem in plants. Passive Transport of Ions: Transport of ions from the epidermis to the xylem without any consumption of metabolic energy merely in consequence of the spontaneous disappearance of non-equilibria driven by a decrease in free enthalpy is known as [...]
In this article, some of the important interactions between nutrient elements as well as between nutrients and other factors are being described briefly. Nitrogen and Micro-Nutrients: Applied N has been reported as a possible cause of Zn deficiency in citrus plants. The application of N fertilizer accentuated the uptake of P and Zn by potatoes. Rice plants grown at low [...]
