Temporal chlorophyll fluorescence signals to track changes in optical properties of maturing rice panicles exposed to high night temperature

Popis výsledku v původním jazyce

High night temperature (HNT) significantly influences rice grain filling dynamics. A novel phenotyping approach using chlorophyll fluorescence was employed to track changes in the optical properties of maturing rice panicles exposed to control and HNT. Two contrasting rice genotypes, Gharib(HNT sensitive) and N22 (highly tolerant), were exposed to control (23 degrees C) and HNT (29 degrees C), from panicle initiation till maturity. Changes in the optical properties of rice panicles throughout maturity were evaluated under field conditions by measuring (i) effective quantum yield of photosystem II efficiency (Phi(II)), (ii) steady-state chlorophyll fluorescence (F-S) and (iii) ratio of emitted chlorophyll fluorescence at 690 and 735 nm, under excitationat 435 nm (F-690/F-735). Numerous vegetative indices (Vis) were correlated with fluorescence measurements to prove the accuracy of the phenotyping method. Phi(II) was selected as the most potent fluorescence parameter (i) to track changi
