Abstract
Abstract Floriculture is a promising activity and has great economic importance. In this context, the cultivation of Lilium pumilum Redouté stands out. However, one of the main challenges flower farmers face is that a large part of the products is lost before reaching the final consumer, due to postharvest losses. Such losses can be minimized by adopting some techniques, such as the use of conditioning solution (pulsing), which has been effective in preventing early senescence. In this sense, this study aimed to evaluate the effect of pulsing with sucrose, citric acid and silver thiosulphate on postharvest conservation of L. pumilum cut flowers. All treatments promoted a 1.8±0.3 day increase in longevity, uniformity of floral opening, and reduced fresh weight loss compared to the control (flowers that were not pulse-treated). There was no significant difference in chlorophyll content and leaf relative water content. The time of exposure to pulsing caused significant differences in the reduction of anthocyanin contents when compared to the control, demonstrating that pulsing preservative solution for at least 6 h extends the vase life of L. pumilum cut flowers by two days.

Summary
The ornamental plant market differs from other agribusiness sectors for its constant investments on the improvement of desirable commercial characteristics. The interest for species that present flowers of easy propagation, with exuberant coloration, constant production throughout the year and accessible costs to producers and consumers (Moura et al, 2010) is notorious. This segment is growing, and this growth creates an increasingly competitive market, which seeks higher quality products every day (Hummel and Miguel, 2017). 27, No 3, 2021 p.344-350 since it responds to market interests (Fu et al, 2020), especially Lilium pumilum Redouté, a species that presents easy reproduction, heights varying from 30 to 50 cm and numerous smooth and linear leaves. The species is suitable for cut flowers, emphasizing the importance of postharvest preservation to lengthen its vase life
