About this eBook

PREFACE The motivation to write this book on experiments arose from having taught both theory and laboratory courses in plant physiology and biochemistry for more than a decade and half. Having supervised and observed students learning theoretical concepts in lectures and performing experiments in the lab for so long a time, I realized that there was sometimes a disconnect between the theory and its application. Students would understand some key phenomenon very well during a lecture but later would find it difficult to place the experiment demonstrating the same phenomenon in its proper context. Vice versa, after performing an experiment successfully, students would sometimes find it hard to relate what they just did in the lab to what happens in real plants under real sunlight and other environmental conditions. This book is my attempt to bridge that perceived gap between understanding and application. There exist a number of excellent laboratory manuals on the subject, and I hope this humble work will find a corner for itself, and go on to benefit students and instructors alike. I would like to thank my family members without whose help and support this work could not have been accomplished. I am also thankful to the Agro Bios India , Jodhpur, India for publishing the manual. Dr. Mrs. Akhtar Inam Associate Professor, Botany Botany Section, Women s College Aligarh Muslim University, Aligarh
