Abstract:
Priming has the image to be a magic tool to improve crop performance. It is certainly true that the startup of the germination process under controlled hydration conditions is a solution for several limitations in seed quality. Priming frequently improves germination rate and may also improve
germination capacity, especially under sub-optimal growing conditions. Priming can alleviate dormancy and extend the temperature range for germination. Three different priming technologies; osmotic, matrix and drum, will be explained and illustrated with examples from various crops. Apart from the benefits, priming may have some downsides as well: shelflife probably will be reduced and the number of micro-organisms in or on the seed may increase. In addition, priming may initiate sensitivity for the development of abnormal seedlings. Hence, the preferred solution is a priming recipe that is fine-tuned to the specific characteristics of a seedlot. Further, it will be explained how priming can be used in combination with other technologies to improve crop performance. Priming can compensate for the negative effect of other seed treatments, for example, the negative effect of a disinfection treatment or of certain pesticides included in a seed coating. It is our belief that an integrated approach of seed and coating technology is the key to improve crop performance.
