The floriculture research program is directed at solving the needs of the floricultural greenhouse industry with using applied research objectives. Many of the projects are industry supported and in cooperation with other OMAF personnel, AAFC Vineland research group and other university personnel.
The projects involve a comprehensive research program to improve various production management techniques for both cut flowers and potted plants through 4 objectives:
- plant modifications through light quality, temperature manipulation, water temperature, change in biorhythm, or other non-chemical means.
- more efficient use of production inputs such as energy, light, carbon dioxide and temperature control.
- more sustainable production through optimizing nutrients and water through recirculation and disease management.
- improvement of increased acceptability through species/cultivar selection or improved postharvest quality of potted plants or cut flowers.
The use of overhead cold irrigation water is an environmentally friendly and an economically competitive alternative to using chemical plant growth regulators for Easter lilies.
