Abstract:

To study the fresh-keeping effects of nano-copper (NC), a novel nano-grade inorganic bactericide, on cut flowers, the vase life, ornamental quality and water relations of cut Gerbera jamesonii ‘Hongyan’ via vase treatments with NC alone and NC plus sucrose were investigated. The results showed that: compared with deionized water (control), the 1, 3 and 5 mg/L NC treatment had no positive fresh-keeping effects on cut gerberas. However, the various concentrations of NC plus 3% sucrose could effectively delay and alleviate the disorders in flower wilting and stem bending in different degrees. Among them, the treatments of 1 and 3 mg/L NC plus 3% sucrose had the most beneficial effects, which could significantly prolong the vase life of cut gerberas, and their fresh weight, and the water uptake and water balance value of cut gerberas were significantly higher than those of the control and NC alone during the whole vase period. In conclusion, appropriate concentration of NC and sucrose combination solution had beneficial fresh-keeping effect on cut gerberas ‘Hongyan’.
