Abstract
Delphinidin-derived anthocyanins are flavonoids that are responsible for the blue color of flowers.
The delphinidin pathway is of interest for genetic engineering for spathe color in anthurium.
One of the requirements for the production of blue flowers is a vacuolar pH >5.0. The association between spathe pH and color for anthurium hybrids was determined to identify potential candidates for engineering of blue-colored spathes.
A total of 50 hybrid selections and cultivars were examined.
Variation in pH between cultivars within each color category was observed, with purple having a pH range of 5.20 to 6.30; green, 6.07 to 6.25; white, 5.67 to 6.13; pink, 5.38 to 6.10; coral, 5.20 to 6.05; orange, 5.12 to 5.70; and red, 5.35 to 5.51. Hybrid selections and cultivars with higher pH values in each of the color categories have the potential for color engineering.
