摘要
取苯甲酸钠、硝酸钾、蔗糖、硫代硫酸银、硫酸铝、多效唑、8羟基喹啉、柠檬酸、矮壮素等试剂,采用不同试剂、不同用量的方法配置喷雾剂或瓶插液,组成7种不同配方的保鲜剂,对黄花百合切花进行喷雾保鲜研究。以蒸馏水作对照,研究雾型保鲜剂对百合切花形态结构及其花被可溶性糖含量的影响,选出效果最好的保鲜剂。结果表明,由瓶插液为30.000g/L蔗糖,喷施液为0.050g/L硝酸钾、0.075g/L苯甲酸钠、0.075g/L硫酸铝、0.100g/L柠檬酸、0.025g/L矮壮素组成的保鲜剂,对百合切花的保鲜效果最好。经雾型保鲜剂喷施处理过的百合切花比对照组的观赏期长2d,花朵直径增加13.9%,薄壁组织细胞的淀粉粒含量多,分解速度慢,维管束清晰可见,形态结构较完整,花被可溶性糖含量高,下降速度慢。该配方能够替代含银离子的配方用于切花保鲜。
In order to study the effects on the preservative sprayed-solutions of the Huang-hua lily cut flowers, seven formulations containing sodium benzoate, potassium nitrate, cane sugar, silver thiosulfate, aluminium sulphate,aspirin, 8-hydroxy quinoline, citric acid, chlormequat, with different concentrations and various combinations, were used as sprayed-solutions liquid and vase liquid. In order to study the changes in morphology and in starch grains in cells of cut flowers were sprayed with various combinations of plant growth regulators and preservative solutions, and the distilled water as a control. The results showed that the best preservation prescription was the cutting treated with vase liquid： 30. 000g/L cane sugar; sprayed-solutions liquid： 0. 050g/L potassium nitrate,0. 075 g/L sodium benzoate, 0. 075 g/L aluminium sulphate, 0. 100g/L citric acid, 0. 025 g/L chlormequat. The flowering duration was two day longer, and the flower diameter was increased 13.9% than that of the control,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 perianth was with a more clear vascular bundles and complete structure,the number of starch grains in cells was more,the content of soluble sugar in perianth was much higher and the decline speed slowed in comparison with the control. This preservative could be a substitution of that containing silver ion.
