| 摘 要： | 探讨9种食用色素对满天星的染色效应。结果表明：满天星对日落黄、胭脂红适应性较好,其次为鸡蛋黄、苋菜红,对混合色素C、果绿、亮蓝、混合色素B、混合色素A适应性较差。不同食用色素适宜的染色浓度和染色时间分别为日落黄（9g/L、2h）、胭脂红（9g/L、3h）、鸡蛋黄（12g/L、3h）、苋菜红（12g/L、4h）、混合色素C（15g/L、4h）、果绿（15g/L、6h）、亮蓝（15g/L、6h）、混合色素B（15g/L、6h）、混合色素A（15g/L、8h）,适宜的pH值分别为8.0,9.9,8.3,9.2,8.0,7.6,6.6,8.9,8.5。切花开放程度大时染色速度快,花枝去叶与否对染色效果影响不明显。染色后的满天星瓶插寿命显著缩短,但能达到切花所要求的4-5d的观赏期。

| Abstract: | In this paper effects of edible pigments on dyeing of cut Gypsophila paniculata were studied.The results showed that Suitable density of those Sunset Yellow,Ponceau 4R,Egg Yolk color,Amaranth,Mixed pigmentsC,Apple Green,Brilliant Blue,Mixed pigments B and Mixed pigments A were 9g/L,9g/L,12g/L,12g/L,15g/L,15g/L,15g/L,15g/L,and18g/L.Suitable time were 2h,3h,3h,4h,4h,6h,6h,6h and 8h.respectively.The dyeing speed was fast when cut Gypsophila paniculata opened in a great degree.Flower stems with more or less leaves were not significant different.The Vase life became shorter after dyeing but still had a period of 4-5 days for ornament. |
