The current book, "Reproductive Biology of Angiosperms," provides an up-to-date description of embryology that highlights the findings of analytical disciplines including Physiology, Biochemistry, Genetics, and Molecular Biology, particularly Gene Action. Significance of Reproductive Biology serves as the introduction chapter in the current book, which concludes with Applications of Reproductive Biology in chapter 21. There are chapters on several facets of angiosperm reproductive biology in between. A few of these chapters have never before been underwritten. For B.Sc. and M.Sc. students of botany, this book is intended to serve as a textbook on the reproductive biology of angiosperms.
