From: Development of a new heat tolerance assay system for rice spikelet sterility
The flow of the assay system of high temperature-induced spikelet sterility. a Rice seedlings two weeks after sowing. One seedling was transplanted to a particular pot and grown at 26 °C (13 h light)/22 °C (11 h dark). b Rice plants one month after transplantation. c Rice plants under heat treatment. The panicle height of rice was fixed 70 cm from the water surface of the artificial rice paddy on heading day. d Rice plants after heat treatment. e Insertion of a thermocouple into flowering cultivars under heat treatment. f Completion of attachment of a thermocouple with a closed flower. g Panicles at 40 days after heading day under normal conditions. h Panicles at 40 days after high temperature treatment
