Abstract
<p>The marketing of strelitzia (<em>Strelitzia reginae</em>) has been increasing due to its beauty, exotic colors and high post-harvest longevity. It has potential to increase also in international exports, however this has been limited by the scarcity of information on the flower post-harvest management and packaging. Therefore, this study aimed to further the technology of strelitzia postharvest to maintain high quality of the product and to select a packaging system suitable for export, ensuring high quality to the final consumer. The damages of the stem and the petal color on the buds of Strelitzia reginae were evaluated and it was observed that the stalks harvested with closed buds had extended longevity, while the flower stalks harvested with the first opened button had the highest flower opening rate. As for mechanical damage, the sleeve net protection most affected the visual appearance of the flowers. The cardboard box packaging showed the lowest percentage of damage in the stems.</p>
Highlights
The strelitzia (Strelitzia reginae Aiton), commonly called bird of paradise, is original from South Africa
This study aimed to evaluate how longevity and color of “arrow” petal of flower stalks of Strelitzia reginae are affected by different types of mechanical damage and to identify the most suitable packaging for transport
The average lifespan was 12.5 days for the stems harvested with the first open button (FRO) and 14.2 days for the Button stage
Summary
The strelitzia (Strelitzia reginae Aiton), commonly called bird of paradise, is original from South Africa. Brazil has great chances to become a significant producer and exporter of flowers and ornamental plants in the world, but there are challenges to be overcome Aspects such as: application of advanced technologies in production systems, use of appropriate genetic material, training and qualification of labor, professional management, market, logistics and distribution, structures of market organization and incentives to technologies and post-harvest packaging need to be improved (Salome, 2007). Often the reduction of these losses is more economically viable than the increase in production For this reason, growers and brokers need to understand the biological and environmental factors involved in the deterioration and employ appropriate post-harvest techniques, delaying senescence and maintaining the best quality of the products (Dias-Tagliacozzo and Mosca, 2007)
