In the science of plant physiology, the study of essential nutrients is paramount to understanding the requirements for plant growth and development. One of the seminal works in this field is the research conducted by Arnon and Schout, which established criteria for identifying essential elements for plant growth. This article delves into the criteria of essentiality proposed by Arnon and Schout, shedding light on their significance and implications in the field of plant biology. Introduction to Essential Nutrients Essential nutrients are substances that are indispensable for the normal growth, development, and reproduction of plants. These nutrients are required in specific quantities and play vital roles in various physiological processes. The identification of essential nutrients is crucial for optimizing crop production and ensuring sustainable agriculture practices. The Contribution of Arnon and Schout In 1951, Daniel I. Arnon and D. D. Schout published a seminal paper titled ...
Sometimes plants get sick and no matter how much you talk to your plant, they won’t talk back. The initial step in determining if a plant has a disease is to look at the signs and symptoms. This can give you a clue about what’s going on. Read full article about | Types of Plant Pathogens and Abiotic Stresses | Click here | Hello I'm Tapsendra Patel and this article will provide you a background on plant diseases and the signs and symptoms common for plant pathogens. A disease is any abnormality that alters the looks or function of a plant. Plant functions are effected by this physiological process. Disease can also reduce yield and quality of harvested product. Disease is a process or a change that occurs over time. It does not occur instantly. Infectious plant diseases are caused by living organisms that attack and acquire their nutrition from the plant they infect. The parasitic organism that causes a disease is a pathogen. Numerous fungi, bact...
