Abstract
The impacts of a-tocopherol, glycine betaine (GB) and salicylic acid (SA) applications on higher plants havebeen the subject of many studies, with special emphasis on oxidative stress tolerance under adverse conditions.However, little work has been carried out on rice responses to a-tocopherol, GB or SA under non-stressconditions, in which yield could potentially increased. This study determined the effects of a-tocopherol (2.3 kgha-1), GB (2.0 kg ha-1) or SA (12.9 g ha-1) application on rice morphology, phenology and physiology undernon-stress conditions. The applications did not affect production of tillers, biomass, phenology, or pollengermination; however, plant height, leaf characteristics and physiology, spikelet fertility (SF), panicle and graincharacteristics and yield were affected. Plants treated with ?-tocopherol, GB or SA showed 6%, 13% and 13.5%increases in grain yield as a result of decreased respiration and increased membrane integrity and SF.
