The increase of phenylalanine ammonia lyase (PAL), phenolic compounds, anthocyanin content and quality of ‘Mahachanok’ mango fruits

The experimental design was randomized complete block design (RCBD) and was divided into five treatments, with each treatment consisting of six applications (per tree). Methyl jasmonate at four concentrations (20, 40, 80 and 120 mg L^-1) was sprayed at the 90 days after anthesis to compare with the control (0 mg L^-1). After harvest at 110 days after anthesis fruits were stored at 15 and 27°C. Physiochemical characteristics were determined every 3 days.
The results showed that mango fruits sprayed with 80 mg L^-1 methyl jasmonate had more phenylalanine ammonia lyase activity, phenolic compound and total anthocyanin content than the control fruit.
L* and a* values of peel were higher than those of the control.
This application resulted in a higher fruit quality, such as β-carotene, vitamin C, glucose, fructose and sucrose content, compared to the control.
