Brassinosteroids are the plant hormone reported to alleviate heat stress. This study investigated the response of rice (Oryza sativa L.cv. Pathum Thani 1) to 24-epibrassinolide (EBR) or 7,8-dihydro-8-20-hydroxyecdysone (DHECD) under high temperature by examine photosynthesis performance and yield. The results show that foliar application of 0.01 μM EBR and 0.1 μM DHECD on V7 vegetative growth could increase the photosynthetic efficiency under 40/30 ºC (day/night temperature). In field growth experiment, the application of those brassinosteroids concentrations on V7 growth stage could increase seed setting in all panicle part and number of normal seeds per particle. The results indicated that EBR and DHECD alleviated heat stress of rice ‘Pathum Thani 1’ by...
