摘要
运用8种植物色素对马蹄莲鲜切花进行染色。结果表明,8种植物色素均能对其进行染色,其中以辣椒红素、柠檬黄和茶黄素最适宜,胭脂红、葡萄紫和靛蓝次之,胡萝卜素与南瓜花黄素较差。适宜的浓度、染色时间及pH值分别为辣椒红素(6g/L、4h、8.7)、柠檬黄(10g/L、5h、9.7)、茶黄素(9g/L、5h、10.4)、胭脂红(15g/L、8h、10.7)、葡萄紫(15g/L、9h、9.4)、靛蓝(20g/L、9h、6.6)、胡萝卜素(15g/L、11h、7.5)、南瓜花黄素(12g/L、12h、7.5)。温度高、湿度小时染色速度快,但分布不均匀,多呈斑形;花梗长度对染色效果影响不明显;瓶插花枝染色较浸泡花朵染色效果好;染色后瓶插寿命均明显缩短。
Eight plant pigments are used to dye of fresh cut Zantedeschia aethiopica, The study proves that they can all dye fresh cut Zantedeschia aethiopica, Pepper Red pigment, Tartrazine and Tea Yellow pigment are the most suitable pigments, followed by Ponceau, Grape Violet and Brilliant Blue. Carotene and Yellow pigment of Cucurbita Moschata Duch-Blossom are not suitable for frest cut Zantedeschia aethiopica. The suitable dyeing density, time and PH for different plant pigment are Pepper Red pigment (6g/L, 4h,8.7), Tartrazine (10g/L, Sh,9.7), Tea Yellow pigment (9g/L,Sh, 10.4), Ponceau (15g/L,8h,10.7), Grape Violet (15g/L,9h,9.4), Brilliant Blue (20g/L,9h,6.6), Carotene (15g/L, 11h,7.5), Yellow pigment of Cucurbita Moschata Duch-Blossom (12g/L, 12h,7.5). It dyes fast, but is not even, appears stain in the condition of high temperature and low humidity. The dyeing effects are not significant for the length of stem. The vast effects are better than the immerse effects. The vast life becomes shorter after dyeing.
