Many factors affect successful establishment of crop stand, one of which being the quality of seeds to ensure rapid and uniform emergence of seedlings. Many vegetables and floral crops are produced year-round, and it is not always possible to sow under favorable conditions all the time. Even if it is possible to control environmental conditions in a modem nursery in which crop seedlings are mass-produced, reducing the nursery period should have a significant impact to production cost. Availability of quality seeds with high germinability has thus become an important issue more than ever. Seed priming is a useful technique in that primed seeds germinate rapidly and uniformly, frequently under less than optimal conditions.
On the other hand, the lack of high-quality labor and the increasing pressure to reduce production cost, especially of small-seeded vegetables and floral crops, necessitate the mechanization of seed planting. Coating the seed would be an ideal approach in this respect. It is not difficult to foresee that the development of a technology in which seed priming is combined with seed coating would be even more desirable. A significant part of the technology has been developed to the level of commercialization in some countries: unfortunately, however, it has been patent-protected in most cases. Development of our own technology is thus an inevitable choice.
In a series of experiments, we hoped to develop seed priming and coating techniques for as many as 11 horticultural crops. Performance of treated seeds was rigorously tested not only in petridishes but in a greenhouse with remarkable success. Finally, the possibility was confirmed that those techniques developed in this study could be industrialized in a large scale.
We are encouraged by the results of this study. The increase of germinability
and possible mechanization of sowing practice would open a new avenue for cost-efficient production of horticultural crops. Some significant findings are
highlighted here.
