Abstract

Rice varieties react to different environments, especially the phytochemical in the seeds. This experiment aims to study the amount of ferulic acid and its antioxidant capacity in landrace rice varieties when grown in different environments. A randomized complete block design (RCBD) with three replication was used. The treatment was designated as five varieties of landrace rice. Rice was grown in three different provinces: Bangkok, Trat and Sakon Nakhon. Data was collected for grain yield per plot, ferulic acid content and antioxidant capacity. The results of combine analysis found that locations were significantly different (P<0.01) for grain yield and ferulic acid content. Rice variety was significantly different (P<0.01) for all traits. Landrace rice with a relatively high average yield in all environments was Klam Feuang. Varieties with high ferulic acid content was Kum Luem Pua whereas Tubtim Chumphae was a variety which highest for antioxidant capacity followed by Kum Luem Pua, respectively. Moreover, no relationship between grain yield, ferulic acid content and antioxidant capacity.
