The book is intended for undergraduate and graduate students of botany, biology, agronomy, horticulture, forestry, and environmental sciences. It is also a valuable reference for researchers and professionals in these fields. The book is richly illustrated with diagrams, graphs, tables, and photos that help explain the concepts and phenomena of plant physiology. The book also includes learning objectives, summaries, questions, and references at the end of each chapter.
Water relations: how plants absorb, transport, and lose water, and how they cope with water stress and drought.
Photosynthesis: how plants capture light energy and convert it into chemical energy, and how they regulate the efficiency and rate of this process.
Respiration: how plants use oxygen and produce carbon dioxide, and how they balance their energy budget and carbon metabolism.
Mineral nutrition: how plants acquire and use essential mineral elements, and how they deal with nutrient deficiency and toxicity.
Plant hormones: how plants synthesize and perceive various hormones, such as auxins, gibberellins, cytokinins, ethylene, abscisic acid, and brassinosteroids, and how they mediate plant growth and development.
The book also provides examples of applied plant physiology, such as crop improvement, biotechnology, stress physiology, phytochemistry, and medicinal plants. The book aims to help students understand the principles and mechanisms of plant physiology, as well as appreciate the relevance and importance of plant science for human society.Plant physiology is not only a fundamental science, but also a practical one with many applications in agriculture, horticulture, forestry, biotechnology, and environmental science. Some of the applications of plant physiology are:
Crop improvement: plant physiology can help to improve the yield, quality, and resistance of crops by manipulating their genetic, physiological, and biochemical traits.
Biotechnology: plant physiology can enable the production of novel compounds, such as pharmaceuticals, biofuels, and bioplastics, by engineering plants or plant cells.
Stress physiology: plant physiology can help to understand and enhance the tolerance of plants to various abiotic and biotic stresses, such as drought, salinity, temperature, pathogens, and herbivores.
Phytochemistry: plant physiology can help to discover and characterize the secondary metabolites of plants, such as alkaloids, flavonoids, terpenoids, and phenolics, that have diverse biological activities and applications.
Life support: plant physiology can help to develop sustainable, closed ecology systems that use plants to provide food, oxygen, water, and waste recycling for space travel and planetary habitats[^3^].
Plant physiology is thus a dynamic and interdisciplinary field that contributes to the advancement of science and society. 061ffe29dd
