Effect of salicylic acid combined with glutamin on rose (Rosa Baccara) cut flowers was studied. The
study was conducted in a factorial arrangement, carried out in a complete randomized design. The factors were
Salicylic acid (0,1, 2 and 4 mM) and glutamin (0, 1.5 and 3 mM).The effects of treatments on the total chlorophyll
content, ACC-Oxidase activity, anthocyanin leakage, membrane stability and malondialdehyde content of cut
flowers of rose (Rosa Baccara.) were investigated. The results showed that the vase solution containing 1.5
mM Salicylic acid with 3 mM glutamin significantly increased vase life compared to the control, in addition, the
malondialdehyde accumulation and ACC-Oxidase activity reduced in the same solution while membrane
stability was improved. Results suggest that Salicylic acid and glutamin increases vase life by affecting many
of the age-related changes associated with Rose petal senescence.
