<p>The development of a plant is a multifaceted, dynamic phenomenon. Due to their immobility, plants respond not only to internal developmental cues, but also to changes in the prevailing environmental conditions. Climate change has increased vulnerability in plants due to increasing concentrations of CO<sub>2</sub> and other pollutants, and fluctuations in the growing environment. These changes affect crop growth and productivity thereby posing a major risk to global food security. </p><p><i>Physiology of Growth and Development in Horticultural Plants</i> contains 22 chapters organized into six sections, beginning with an introduction on basic concepts of plant growth and development; followed by genetic basis of plant development; quantification of growth; and sensing and response of plants to various environmental signals. It also explores plant growth hormones and their role either singly or in combination in controlling various aspects of plant growth and development, and hormonal
