One characteristic physiological symptom of potassium (K +) deficiency in higher plants is the accumulation of amino acids and amides in the tissues.This chapter discusses high‐protein crops and the role of K + in their metabolism. This publication briefly summarizes plant mineral nutrition and what is known about how different nutrients affect different types of plant diseases (fungal, bacterial, viral, and soilborne) and pests. It also contributes to the survival of plants exposed to various biotic and abiotic stresses. It is important in carbohydrate breakdown which furnishes energy for plant growth. Potassium (K) plays a pivotal role in sugarcane production. You are currently offline. It is an essential nutrient for plant growth and its role in sugarcane has been well documented. Role of potassium in plants pdf Potassium is vital to many plant process- es. Potassium is an essential plant nutrient that improves root growth and plant vigor, helps prevent lodging and enhances crop resistance to pests and diseases. Toxicity occurs when a nutrient is in excess of plant needs and decreases plant growth or quality. Potassium is a necessary element for all life. Potassium also increases drought resistance in plants and aid in reducing plant water loss As an essential macronutrient, potassium (K +) plays crucial roles in diverse physiological processes during plant growth and development.The K + concentration in soils is relatively low and fluctuating. Potassium plays a vital role in the winter survival of turfgrass, disease resistance, and in increasing the overa II hardi ness of the grass plant. Potassium, the most abundant intracellular cation, is an essential nutrient that is naturally present in many foods and available as a dietary supplement. Additionally potassium also plays a significant role in photophosphorylation, turgor maintenance, photoassimilate…, Potassium: A Vital Regulator of Plant Responses and Tolerance to Abiotic Stresses, 1 Potassium : A vital regulator of plant responses and 2 tolerance to abiotic stresses 3, Effect of pre-sowing Application of Nitrogen, Potassium and Sulfur and its relationship on Egyptian Cotton Productivity, Influence of Potassium Foliar Application on Cotton Yield (Gossypium barbadense L.) under Saline Condition, Response of Cotton Plant to Spraying Some Natural Materials Under Water Stress Conditions, Agronomic performance of colored cotton influenced by irrigation with treated domestic sewage and potassium fertilization in semi-arid region of Brazil, EFFECT OF WATER STRESS AND FERTILIZATION ON COTTON PRODUCTIVITY UNDER CALCAREOUS SOIL CONDITIONS. In addition to summarizing the impor-tance of K+ retention for plant salt tolerance, we focus onaspects that were not the subject of previous reviews including (1) the importance of HAK/KUP family of transporters in K+ uptake in salt stressed plants … Protein and starch synthesis in plants require potassium as well. Potassium (K), along with nitrogen and phosphorus, is one of the three essential plant macronutrients, and is taken up by crops from soils in relatively large amounts. Current upgrades and findings in the area of K biology have successfully highlighted its role in plant growth, metabolic functions as well as efficient agriculture. Apart from water and mineral salts the next major substance in plant … Potassium plays an essential role in photosynthesis and metabolism of plants. Fischer RA. Alfalfa was grown hydroponically in 0, 0.6, and 4.8 millimolar K in order to determine the influence of tissue level of K on photosynthesis, dark respiration, photorespiration, stomatal and mesophyll resistance to CO2, photosystem I and II activity, and synthesis and activity of ribulose 1,5-bisphosphate carboxylase (RuBPc).
