Seasonal differences in potted miniature roses post-production longevity of Academic Article uri icon


  • To assess the effects of summer-like (high-temperature-long-day or HTLD) vs. winterlike (low-temperature-short-day or LTSD) growing conditions on production quality and post-production longevity of potted miniature roses, plants of Rosa L. 'Meirutral' and 'Meijikatar' were grown in growth chambers using a short-cycle production schedule. Plants grown under the HTLD environment had more flowering shoots than those grown under the LTSD environment due to a decrease in blind shoot formation as plants in both environments had the same total number of shoots at flowering. In addition, plants grown in the HTLD chamber exhibited longer post-storage floral longevity and whole plant shelf life than plants grown under LTSD conditions regardless of simulated shipping treatment. These results suggest benefits from summer production of potted miniature rose plants and the possibility of using a higher temperature forcing regimen than is normally recommended with supplemental lighting for winter production.
