| Abstract | High temperature in the reproductive stages is an important factor to determine grain yields because the florets are sterile. In this research, Jao Hom Nin mutant lines No. 7988 and 7766 that showed high and low seed set, respectively and wild type were used to observe in greenhouseat 40-45 oC for 6 hours/day from booting stage until harvesting. The pollen viability, pollengermination, seed set and Heat-shock genes expression including, OsHsfA7, OsHsfA9, OsHsfA2eand OsHsfA4d in flag leaf and young flower were evaluated. The result showed that pollen germination and seed set under normal condition were higher than under high temperature condition, but pollen viability not different. To evaluate HSPs genes expression, OsHsfA7,OsHsfA2e and OsHsfA4d showed high expression both of tissues in high temperature condition. Thus, HSPs genes will express at high level when rice plant is treated with high temperature stress. |
