- 摘要:
- 以‘冰山’和‘萨曼莎’月季为试材，采用不同pH缓冲液（1、3、5、7、9、11）处理月季切花和花瓣花青素提取物，利用植物比色卡对比其颜色变化，研究了不同pH缓冲液对白色和红色月季花瓣颜色及花青素提取物的影响。结果表明：不同pH缓冲液处理对白色月季‘冰山’花瓣颜色影响差异不大，但对红色月季‘萨曼莎’的花瓣颜色影响差异较大，在pH 1缓冲液处理中比色值由53C变为53A，而在pH 9和 pH 11缓冲液处理下，比色值由53C变为61B；不同pH缓冲液对白色月季‘冰山’花青素提取物影响不明显，而对红色月季‘萨曼莎’影响较大。随着pH缓冲液浓度的增加，月季‘萨曼莎’花青素溶液的颜色从深红色、红色向棕红、红褐色转变，颜色逐渐变深、变暗。
- Abstract:
- Rosa hybrid in white variety ‘Iceberg’ and red variety ‘Samantha’ were taken as materials,the effects of different pH buffer treatments(1,3,5,7,9,11) on the petals color of both cut flower and petal extract were studied,and assessed by colored cards.The results showed that there was little difference in the effects of different pH treatments on the petals color of white variety ‘Iceberg’,for red variety ‘Samantha’,there was large difference on the petals color.The colorimetric value changed from 53C to 53A when exposed to pH 1,while changed from 53C to 61B when exposed between pH 9 and pH 11.There was little difference in the effects of different pH treatments on the petal extracts of white variety ‘Iceberg’.For red variety ‘Samantha’,there was large difference on the petal extracts.
