Seed storage, germination, quality, and enhancements.

Abstract

To fully comprehend the complexities of vegetable crop growth and development, we must understand seed physiology related to storage, germination, quality, and enhancements. The challenge is to present an in-depth knowledge of vegetable seeds that covers considerable diversity with respect to botanical classification, seed size, and composition. This chapter encompasses 33 common vegetable crop seeds from ten plant families (Alliaceae, Liliaceae, Poaceae, Apiaceae, Asteraceae, Brassicaceae, Chenopodiaceae, Cucurbitaceae, Fabaceae and Solanaceae). This diverse group of plants makes a comprehensive overview of vegetable seeds difficult to achieve, especially since there is little scientific literature on seed physiology of many small-seeded crops of minor economic importance. Due to these limitations, several approaches are listed to develop a coherent picture of vegetable seeds. Relative differences between seeds are shown with regard to seed size and composition, storage longevity, seed and seedling morphology, temperature requirements for germination, and the use of reserve materials during emergence. More generalized information is presented on factors and events associated with storage, germination, and aging. Finally, the process of aging and other aspects of seed physiology and technology are illustrated using specific crop examples.
