Preservative solutions on vase life and quality of cut Polianthes tuberosa L.

Abstract

This experiment was conducted to study the effectiveness of different preservative solutions on vase life and quality of angelica cut inflorescences cv. Single. The concentrations of citric acid at 100, 200 and 300 mg L-1, sucrose at 3% and 4% and H2O2 at 0.1%, 0.2% and 0.3% were used as preservatives, while distilled water was used as control. The single factor experiment was laid out in a completely randomized design (CRD) with three replications. Citric acid and H2O2 solutions effectively inhibited bacterial growth-related blockage in the vascular tissues, but had adverse effects on the vase life. The inflorescences stored in sucrose (3% and 4%) solutions remained fresh up to 10 days after preservation (DAP), maintaining good solution uptake, controlling transpiration loss and gaining higher relative fresh weight. Different quality parameters like floret diameter and number of opened florets were also significantly higher in inflorescences preserved in sucrose (3% and 4%) solution, followed by control, citric acid and H2O2, respectively, in different DAP. Overall, the inflorescence of cut tuberose preserved in sucrose, particularly at 4% solutions, showed better postharvest quality than other preservatives and maximum vase life.

Effects of organic acids, chemical treatments and herbal essential oils on the vase life of cut carnation (Dianthus caryophyllus L.) flowers

“…This variability in pH over the life of the vase may be related to the solutions in the vase, the transport physiology of the plant, and the amount of microorganisms in its metabolism. Similar results were found by Shanan (2017) and Paul et al, (2021) is also seen in their study.…”

The Use of Hydrogen Peroxide and Silver Nanoparticles in Horticulture

“…Its action is related to the inhibition of the multiplication of microorganisms in the storage ____________________________________________________________________________________________________________________ solution and in the conductive bundles, through which silver reaches the flower, where it silences the ethylene biosynthesis genes, which are of great importance for the durability of climacteric plants (Basiri et al 2011;Naing & Kim 2020). The positive impact on the durability of cut flowers has been reported in, for example, carnation (Sedaghathoor 2015), gladiolus (Li et al 2017), tree peony (Zhao et al 2018), gardenia foliage (Lin et al 2019), snapdragon (Rabiza-Świder 2020), peony (Skutnik et al 2020a), garden cosmos (Skutnik et al 2020b), Thalictrum aquilegifolium (Poniewozik et al 2020), lisianthus (Skutnik et al 2021), tuberose (Paul et al 2021), Strelitzia (Thakur et al 2022), alstroemeria (Anvari et al 2022, and rose (Ha & In 2022). Nanosilver was mainly applied as pulse treatment at 5-20 mg•l -1 for 24 h or as a permanent presence in the liquid in which flower stalks were immersed.…”
