Effect of GA4+7 treatment on the capsaicinoid content of chilli (Capsicum annuum L. var. Kulai)
The effect of GA4+7 treatment on the capsaicinoid content of chilli was studied in chilli fruit grown under glasshouse and field conditions. The major capsaicinoids – capsaicin (CAP), nordihyrocapsaicin (NDHC) and dihydrocapsaicin (DHC) were separated and quantified by HPLC and their identity furthe...

| description | The effect of GA4+7 treatment on the capsaicinoid content of chilli was studied in chilli fruit grown under glasshouse and field conditions. The major capsaicinoids – capsaicin (CAP), nordihyrocapsaicin (NDHC) and dihydrocapsaicin (DHC) were separated and quantified by HPLC and their identity further confirmed by GCMS. Higher total capsaicinoid content was obtained with GA4+7 treatment compared with the untreated control. More pronounced effect of GA4+7 was observed on NDHC and DHC. The capsaicin content was significantly increased by GA4+7 treatment at peak flowering (PF) and with double application at early flowering and peak flowering (EF + PF) only. The difference between glasshouse and field treated fruit was not significant. |
