الملخص EN

The research was carried out in the Storage Research Laboratory of the Department of Horticulture Sciences at the University of Damascus, during the year 2020, the aim of studying the effect of cold storage, treatment with boric acid and salicylic acid, and preservation in preservative solutions containing hydroxyquinoline 8HQC, in increasing the post-harvest life of gladiolis flowers.

Postharvest life was estimated, vase-life, time to open the first 5 basal florets / day, amount of water uptake rate,% fresh weight change, percentage of florets opening Percentage of opened florets per spike.

The results of the statistical analysis showed a significant superiority of cold storage in maintaining flower quality and increasing post-harvest life (31.24 days) compared to control flowers (11.4 days).

Treatment with boric and salicylic acid at a concentration of 300 mg / L increased the time needed to open the florets and increased the amount of water uptake rate within the cold storage (156 and 155 ml, respectively) and significantly affected the increase in the percentage change in weight%.
