Postharvest Life of Cut Rose Flowers as Affected by Salicylic Acid and Glutamin
نویسندگان
چکیده
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. Abbreviations: SA Salicylic acid MDA Malondialdehyde ROS Reactive oxygene species ACO ACC-Oxidase

Improvement in vase life of cut rose cv. “Dolce Vita” by preharvest foliar application of calcium chloride and salicylic acid
Rosa hybrida L. is an important commercial cut flower. Salicylic acid (SA) and calcium chloride (CaCl2) act as endogenous signal molecules responsible for growth parameters in plants. The aim of this study was to evaluate the effects of preharvest SA and CaCl2 treatments in extending the vase life of cut rose flowers. Therefore, a factorial experiment based on completely randomized design with ...
متن کاملDelaying of Postharvest Senescence of Lisianthus Cut Flowers by Salicylic Acid Treatment
Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...

Experiments were conducted to evaluate the response of different originated (the same mother plants with different growers from different cities in Ethiopia) cut rose flowers to various relative humidity (RH) and recut (recut and non-recut). Three different experiments (E1, E2 and E3) using three RH (60, 75 and 90%) and three Ethiopian growing areas (Fleur, Liki and Longonot) with 10 replicatio...

The postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. Cut roses were obtained from commercial area of Siliguri. To assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (CA) (300 mg/ml) and 8-...
