Analysis of the Comparative Study on Flower Pigments with Phenylalanine Ammonia-Lyase Activity in Orchid Plants | Chapter 5 | Challenging Issues on Environment and Earth Science Vol. 3

 Plants in the Orchidaceae family have long been one of the most significant commercial products in the agricultural industry. The flower petals can be used as cut flowers as well as potted flowers because they have eye-catching pigments.

The main pigments found in orchid flower petals, as well as their relationships with phenylalanine ammonia-lyase (PAL) activity, were investigated.

The total anthocyanin content of six separate orchid petals was measured using spectrophotometry, and the values ranged from 0 mg/g (in Dendrobium Shavin white) to 2.128 mg/g (in Dendrobium Shavin red) (in Mokara Aranda). The petals with vibrant colours have a lot of anthocyanin, while those with pale colours have a lot of chlorophyll. When compared to -carotene and chlorophyll content, total anthocyanin content was found to be the highest. In a correlation study, PAL behaviour was found to be significantly positive correlated with anthocyanin material.

Conclusion: The findings suggest that the PAL enzyme may be used as a biomarker for orchid flower colour.
