The aim of seed storage is to preserve their physiological and sanitary quality for as long as possible. This depends on prior knowledge of the physiological behavior of the seeds during storage, the appropriate choice of packaging and constant monitoring of the environmental conditions prevailing in the storage environment. Proper seed storage is essential to make agricultural production viable and also in seedling production programs aimed at recovering degraded areas, as well as representing one of the pillars for conserving plant genetic heritage in germplasm banks. This publication is aimed at the public interested in learning about basic aspects of seed storage. In this second volume, we present a literature review on seed treatment in soybean, corn and sweet corn crops. We hope you enjoy reading it.
