Abstract
This study was conducted at the Postharvest Laboratory of Vegetable and Ornamental Plants Department, Faculty of Agriculture, Mansoura University, Egypt, during 2014 and 2015years. It aimed to study the effect of silver nitrate, nano-silver particles and cold storage on vase life and quality of cut roses. Cut roses (Rosa hybrida L.) of two local cultivars (Red and White) were placed in distilled water, 10 ppm silver nitrate, or 5 ppm nano silver particles for three hours either fresh (without storage) or pulsed after they have been wrapped in newspapers and stored dry (without water) inside a refrigerator at 5 ±1 °C for 24, 48, and 72 hours. Vase life and quality (expressed as maximum increase % of original fresh weight) of the flowers were determined under laboratory conditions (24 hours fluorescent light about (1500 lux), 25 ± 2˚C, and 50 ± 5% relative humidity (RH)). The results showed that the two cultivars have different vase lives as the white cultivar had longer vase life than the red one, while the red gained more fresh weight than the white one.As for the effects of storage period, data showed that increasing the storage period reduced the useful vase life of the flowers, while resulted in more weight gain by the flowers.Both silver nitrate and nano silver pulse extended the vase life of the flowers with favor to silver nitrate pulse. The best treatments led to the longest vase life was that of the non-stored flowers pulsed with silver nitrate for both white (9.8 days), and the red cultivar (7 days).
