Abstract

This experiment was carried out to investigate the effect of sodium nitroprusside (SNP) as a nitric oxide (NO) donor compound on postharvest life of a cut rose cultivar (Rosa hybrida ‘Utopia’). At laboratory with 21 ± 2ºC temperature, 70% relative humidity, and 12h photoperiod, flowers were treated with SNP (0 (Control = Distilled water), (50 and 100 µMolar) solutions for 24 hours and then were transferred to distilled water and were held in distilled water until the end of the vase life. Soluble protein content, solution uptake rate, relative fresh weight, total chlorophyll (a+b) content, and vase life of flowers were determined. Results showed that flowers treated with 50 µMolar SNP had more soluble protein content compared to control. SNP (50 µMolar) application increased solution uptake rate of flower stems. Also flowers treated with 50 µMolar SNP had more relative fresh weight compared to control significantly. SNP (50 µMolar) increased vase life of cut rose ‘Utopia’ from 11 days (control) to 13.3 days.

Highlights

This experiment was carried out to investigate the effect of sodium nitroprusside (SNP) as a nitric oxide (NO) donor compound on postharvest life of a cut rose cultivar (Rosa hybrida ‘Utopia’)
Cut rose flowers ‘Utopia’ treated with 50 and 100 μMolar Sodium nitroprusside (SNP) had more soluble protein content compare to control on 10th day. 100 μMolar SNP treatment had not significant superiority to control at last evaluation
In a previous experiment application of DETA/Nitric oxide (NO) (10 mmol) as a NO donor compound did not have any effect on soluble protein content of cut rose ‘First red’ (Chamani, 2005)

Summary

Introduction

This experiment was carried out to investigate the effect of sodium nitroprusside (SNP) as a nitric oxide (NO) donor compound on postharvest life of a cut rose cultivar (Rosa hybrida ‘Utopia’). Solution uptake rate, relative fresh weight, total chlorophyll (a+b) content, and vase life of flowers were determined. NO is applied as fumigation and NO donor compounds to extend the postharvest life of cut flowers (Sankhla et al, 2003; Wills et al, 2003).
