Abstract

Chrysanthemum is an important commercial cut flower that is emerging in the floriculture industry. Pulsing is a primary concern in the commercialization of flower as after harvest flowers tends to lose their freshness. Among the different pulsing solution used to improve the vase life of chrysanthemum, Sucrose and Sodium hypochlorite has emerged as potent holding solution that can delay the senescence and improve the post-harvest life of Chrysanthemum. In this experiment, we studied the potential of Sucrose and Sodium hypochlorite in improving the vase life of Chrysanthemum cv. ‘White Star’. The challenges of the study Chrysanthemum spike were harvested at the flower bud stage and the temperature was approximately 18°C, the uniform flowers were cut and immediately stood upright in buckets partially filled with de-ionized water. The latter stage proved that sucrose and NaOCl prolonged the vase life of the Chrysanthemum flower. The overall best treatment for different parameters for improving the vase life of chrysanthemum during the season 2021-2022 were recorded under the treatment T8 (Sucrose 20 % + NaOCl 50 ppm) 2 hours followed by the treatment T6 (Sucrose 10 % + NaOCl 50 ppm) 2 hours and T4 (Sucrose 5 % + NaOCl 50 ppm) 2 hours while pulsing with T0 Control (de-ionized water) adversely affected the different post-harvest parameters of Chrysanthemum.

Conclusion

Results of the present study suggest that the overall best treatment for different parameters for improving the vase life of chrysanthemum during the season 2021-2022 was recorded under the treatment T8 (Sucrose 20 % + NaOCl 50 ppm) 2 hours followed by the treatment T6 (Sucrose 10 % + NaOCl 50 ppm) 2 hours and T4 (Sucrose 5 % + NaOCl 50 ppm) 2 hours, which significantly improved the post-harvest quality of chrysanthemum spikes. The various holding solutions significantly improved the different post-harvest parameters in Chrysanthemum viz., days to bud opening, fresh weight of flower, flower height, stem diameter, total solution consumption, total moisture loss in cut flower, dry weight of spike, flower diameter, flower weight, water uptake, mean transportation loss of water however minimum response was noted under control. The biochemical attributes such as relative water content, electrolyte leakage, total soluble solids and total sugar significantly influenced and performed better under these treatments.
