摘要

This paper reviews the efficacy of seed treatments in improving the consistency of seed performance and, consequently, crop yield and quality. Coating technologies, pelleting, encrusting and film-coating are used increasingly to ease seed sowing by altering seed shape, surface properties, and weight. These techniques are also used to deliver a range of beneficial additives, including micronutrients and plant protection agents. Seed vigour or physiological status can be manipulated by hydration treatments, such as priming and steeping. Eradication of fungal and bacterial seed infections can be achieved through heat or biocide treatments, although there are challenges in operating these processes at an industrial scale without jeopardizing viability, vigour and shelf life. Since seed enhancement is a means of reducing the inherent variation in seed to release its genetic potential, it is vital that the variation between seeds and seed lots is fully characterized when developing a new technology. It is also noteworthy that while relatively few seed lots are evaluated in the academe, a commercial seed enhancement company may routinely treat thousands of lots from the same species with a particular process. This paper provides insights into the development of techniques for seed enhancement.
