Abstract:

Rice endophytes can produce enzymes such as cellulase which improve quality, increase yield, enhance nitrogen fixing capacity and improve resistance. This study aimed to improve the antioxidant capacity of black rice by spraying rice with endophytes at the heading stage. The results indicated that there were significant differences in the effects of different endophytes on the antioxidant capacity of black rice and the effects of endophytes on antioxidant capacity varied amongst different rice varieties. Eight endophytes were found to significantly improve the total antioxidant capacity (T-AOC) of the black rice variety "1C902". The highest increase in antioxidant capacity was 6.3 times, with an increase of 832.838 IU g-1. Six strains were found to significantly improve hydroxyl radical-scavenging capacity (SFRC) of black rice "1C902". The highest increase in SFRC was 1.3 times, with an increased amount of 1855.348 IU g-1. Three strains were found to significantly increase T-AOC in black rice "1C903". The highest increase in T-AOC was 1.1 times, with an increased amount of 946.455 IU g-1. Four strains were found to significantly increase SFRC of black rice "1C903". The highest increase in SFRC was 82.1%, with an increased amount of 848.189 IU g-1.
