High night temperature-induced accelerated maturation of rice panicles can be detected by chlorophyll fluorescence
Original language description
Rice panicle maturation is considered to be highly sensitive to environmental conditions. Since one of the factors accompanying global climate change is increases in minimum night temperatures more pronounced than those in maximum day temperatures, the effect of high night temperature (HNT) on rice panicle maturation was investigated. Two rice genotypes with contrasting HNT responses, N22 (highly tolerant) and Gharib (susceptible), were exposed to control temperatures (ca 23°C) and HNTs (ca 29°C) from flowering until maturity. Loss of photosynthetic activity and/or pigments during rice panicle maturation were evaluated temporally by measuring (i) effective quantum yield of photosystem II efficiency (?II), and (ii) steady-state chlorophyll fluorescencelevel (FS). To prove the accuracy of the new approach presented in this study, several vegetative indices were calculated from reflectance measurements and correlated with fluorescence parameters. It has been observed that ?II tracks the
