We at CRRI are using hand-held chlorophyll fluorescence meter to predict the vitality of photosynthetic apparatus damages due to submergence.
Besides, they constitute important UV absorbing compounds which prevent DNA and photosynthetic apparatus damage (Mattoo, 1999; Wink, 2003; Hartmann, 2007; Wallace, 2007).
In addition, both the maximal efficiency of PSII photochemistry (FV/Fm) and the performance index (PIABS) decreased significantly in K. striatum at 23 °C, indicating that the photosynthetic apparatus was damaged at 23 °C.
In our study, the decrease of the photosynthetic O2 evolution rate under heat stress was associated with electron transport capacity, which showed that the PSII of the photosynthetic apparatus was damaged.
The lubricating behavior of BSG is evaluated by a specifically designed apparatus without damaging its natural structure.
For example, the coral's bleaching response is thought to be triggered by its symbionts, whose photosynthetic apparatus becomes increasingly damaged under thermal stress both in photosystem II (PSII) [15], and in the dark reactions of photosynthesis [16].
Due to this accumulation, the photosynthetic apparatus may be damaged by Na+ and the photosynthesis will significantly decrease.
Moreover, the cell wall can be considered, in conditions where the photosynthetic apparatus might be damaged or not properly working, as a temporary source of carbohydrates.
Under moderate to mild drought where the photosynthetic apparatus is not damaged (Cornic and Briantais, 1991), carbon assimilation is first reduced by stomatal closure (and thus reduced ci).
Turkey is a bridge between the East and the West, and the threat of Turkey becoming a gateway of terrorism to Europe has to be considered, particularly as a NATO country with a crippled and severely damaged counterterrorism apparatus without an experienced and trained counterterrorism police and military force.
Chilling reduced RGR and damaged the photosynthetic apparatus in both varieties, however NM94 seedlings can sustain the maximum photochemical efficiency of PSII and DPPH scavenging activity better than VC1973A under chilling.
