Title: Study the Preservative Effect of Sodium Benzoate on the Cut Flowers
Abstract: In order to study the effects on the preservative with sodium benzoate or silver ion of the Gerbera jamesonii yellow flower and the Dendranthema morifolium yellow flower,more formulations containing cane sugar,silver nitrate,potassium aluminum sulphate,chlormequat,Vc with different concentrations and various combinations were treated with sodium benzoate solution or silver ion solution.In order to study the changes in morphology and in starch grains in cells of cut flowers,they were treated with preservative solutions,and the distilled water as a control.The results showed that the preservative effect with sodium benzoate is equal to the silver ion.The Dendranthema morifolium yellow flower treated with preservative was about fourteen days longer than that of the distilled water,and the Gerbera jamesonii yellow flower treated with preservative was about ten days longer than that of the distilled water,and the time of withering was much prolonged and the flower color was more fresh.The decomposition rate of cells in parenchyma tissue was delayed and the tissue in corolla was with a more clear vascular bundles and complete structure,the number of starch grain in cells was more,the content of soluble sugar in corolla was much higher and the decline speed slowed in comparison with the controls.This preservative with sodium benzoate could be a substitution of that containing silver ion. And effective surmounted the neck-bending phenomena in Gerbera jamesonii.
