【摘要】 以非洲菊(Gerberajamesonii)切花为材料,以不同浓度的蔗糖(g/L) +8-HQ(mg/L) +柠檬酸(mg/L) +K2HPO4·3H2O(mg/L)复合液与蒸馏水作对比实验,通过比较可溶性蛋白质和超氧化物歧化酶(SOD)值的变化情况,探讨了非洲菊切花的保鲜效果,结果表明,保鲜剂对非洲菊切花的寿命、花径、观赏品质的影响都有着显著的差异; 保鲜剂能减缓可溶性蛋白质和SOD的下降趋势, 25g/L蔗糖+250mg/L8-HQ+65mg/LK2HPO4·3H2O为适宜的保鲜剂配方。更多还原

【Abstract】 Cutting flowers of African chrysanthemum （Gerbera jamesonii） were kept in compound preservative solutions with different concentrations of sucrose, 8-HQ, citric acid and K₂HPO₄·3H₂O and those kept in distilled water were used as the control. The changes in soluble protein content and in SOD activity were determined. Preservative treatments significantly slowed down the decline in protein content and SOD activity, increased the life-span of the flowers and improved their quality. The optimum formulation for the preservative was sucrose 25 g/L + 8-HQ 250 mg/L + K₂HPO₄·3H₂O 65 mg/L.更多还原
