Abstract

A study was conducted on cut Nerine sarniensis cv. Red scapes to assess the effects of postharvest dry storage at different temperatures on their overall postharvest performance. The main objective of the study was to develop a simple and cost-effective storage protocol to bring out easy transportation of the cut flower crop without affecting its subsequent post harvest life. For dry storage, the scapes were stored at different temperatures, 5, 10 °C and room temperature (21 ± 2 °C) in moistened filter papers and kept in storage for 72 h. After storage, the scapes were transferred to different holding solutions under laboratory conditions to compare their efficiency in enhancing the vase life of the cut scapes. The effect of different storage temperatures on vase life, blooming, volume of holding solution absorbed, floral fresh and dry mass, membrane stability, soluble proteins, α-amino acids, sugars and total phenols, was studied. Storage of scapes at 5 and 10 °C for 72 h and transferred to holding solution containing sucrose + HQS resulted in enhancement in vase life compared to that of scapes kept at higher temperatures. The scapes stored at 5 °C before transfer to holding solutions registered a vase life of 3, 5 and 7 days in DW (distilled water), SUC (0.15 M sucrose) and SUC + HQS (0.15 M Sucrose + 50 mg L−1 8-hydroxyquinoline sulphate) respectively. The increment in vase life was found associated with higher soluble protein and sugar content in the perianth tissues. The present results suggest that the scapes of N. sarniensis cv. Red may be cool and dry, stored at temperature as low as 5 °C for 72 h before transferring them into vase solutions without affecting their subsequent vase life.
