I feel immense pleasure in presenting this book to the students. The field of plant physiology includes the study of chemical and physiological processes within the plants. This book of plant physiology lucidly explains the operational mechanisms of plants with the help of illustrations. It focuses on the study of the internal activities of plants including molecular interactions of photosynthesis, photoperiodism, seed dormancy, plant hormones, plant stress and bioenergetics. The book with its compilations and update literature and its lucid presentation will be useful for students, teachers and others in the subject of plant physiology.
I wish to express my gratitude to my teacher Prof. (Dr.) Vibha Khanna for her guidance and my colleagues. I am also grateful to my husband Dr. Hemant Kumar for his valuable support.
