Abstract

Safflower (Carthamus tinctorius L.), belonging to the Asteraceae family, originating in Asia, is considered one of the oldest agricultural crops, with records dating back to 4.500 BC, extraction of food, medicinal and biodiesel oil, animal feed, and floral stems for ornamentation. In Brazil, cultivation is still relatively new, requiring studies regarding the post-harvest of its floral stems, which have an ornamental character due to their beauty, rusticity and versatility of use. The objective of the present work was to evaluate the post-harvest quality and durability of safflower flower stems treated with different pre-cooling periods and preservative solutions. The experiment was conducted with a completely randomized design, organized in a 3x7 factorial scheme (pre-cooling periods and preservative solutions), with four replications, and each experimental unit consisted of five flower stems. The average diameters of the inflorescences and stems were evaluated, as well as the durability of a healthy and marketable aspect. It was observed that the durability of the safflower flower stems was favored with pre-cooling, and when combined with different preservative solutions, they present up to 12 days of pot life. Recommended treatment is a combination of preservative solution containing distilled water + 20 mg L-1 of citric acid and a pre-cooling period of 24 h.

不同预冷期和保鲜剂对红花花茎采后品质的影响

红花(Carthamus tinctorius L.)，属于Asteraceae科，原产于亚洲，被认为是最古老的农作物之一，有记载可以追溯到公元前4500年，用于提取食物、药用和生物柴油、动物饲料和装饰花茎。在巴西，种植仍然是相对较新的，需要研究其花茎的收获后，由于其美丽，质朴和用途广泛，具有观赏特性。本研究的目的是评价不同预冷期和不同防腐剂处理的红花花茎采收后的品质和耐久性。试验采用完全随机设计，按3x7析因方案(预冷期和防腐剂溶液)设计，4个重复，每个实验单元由5个花茎组成。评估了花序和茎的平均直径，以及健康和市场方面的耐久性。观察到，预冷有利于红花花茎的耐久性，当与不同的防腐剂溶液结合使用时，红花花茎的盆栽寿命可达12天。建议使用含有蒸馏水的防腐剂溶液+柠檬酸20mg L-1，预冷时间为24h。
