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.
