- Abstract
Safflower (Carthamus tinctorius L.) is still a relatively new crop In Brazil, this way, studies regarding the postharvest of its floral stems are required. They present an ornamental character, because of their beauty, rusticity and versatility of use. The objective of this study was to assess the post-harvest quality and durability of safflower floral stems at different pre-cooling periods and conservative solutions. It was used a completely randomized design, organized in a 3x7 scheme (0; 12 and 24 h periods, and conservative solutions: control (distilled water (DW)); DW + 2% sucrose; DW + 2% sucrose + 2% sodium hypochlorite; DW + 20 mg L-1 of gibberellic acid; DW + 20 mg L-1 of citric acid; and DW+ 20 mg L-1 of salicylic acid). Each experimental unit consisted of five floral stems. Assessments were made on the average diameters of inflorescences and stems, as well as on vase life, which was measured by their durability with a healthy and marketable aspect. It was observed that the durability of safflower flower stems was favored by pre-cooling, and when combined with different preservative solutions, their vase life reaches up to 12 days. Thus, it is recommended the use of a preservative solution containing distilled water + 20 mg L-1 of citric acid and a pre-cooling period of 24 h, in order to preserve the durability of safflower floral stems.
