The scientific study of seeds, their structures and processes falls under the domain of seed science. A seed is an essential part of the plant. It is formed during the reproduction process in spermatophytes, including gymnosperm and angiosperm plants. Angiosperm seeds consist of three chief constituents- the embryo, the endosperm and the seed coat. In angiosperms, seed development begins with double fertilization. They are essential for the nourishment of the embryo. Seed production in plants is affected by weather conditions, diseases, insects, etc. They are found in various shapes such as bean shaped, triangular, square, spherical and lenticular among many others. Many crops, forest trees, legumes, turf grasses, etc. are propagated through seeds. This book includes some of the vital pieces of work being conducted across the world, on various topics related to seed science. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included in this book. It will provide comprehensive knowledge to the readers.
