Despite the stomatal limitation of photosynthesis, the maximum photochemical efficiency of PSII ([F.sub.V]/[F.sub.m]) was not affected by the water deficit, i.e., no significant difference was observed between control plants and those subjected to water deficit (Figure 2).
The decline of qP and ETR show that the portion and efficiency of the PSII antenna pigments capturing light energy for photochemical electron transfer were decreased.
The chlorophyll fluorescence parameter [F.sub.v]/[F.sub.m] is broadly used to estimate the maximum quantum yield of PSII photochemistry.
The galled tissues had a higher minimal fluorescence of PSII in the dark-adapted state ([F.sub.0]) than the non-galled tissues (AV = 389.5 [+ or -] SE = 20.9 and AV = 313.9 [+ or -] SE = 12.7, respectively).
It seems that thermal stress alone did not lead to a formation of triplet chlorophyll in PSII, the starting point for 1[O.sub.2] production (Lesser, 2006), most likely because of the low light intensity of the experimental treatment, which limited the amount of excess energy.

In the light reaction phase of photosynthesis, most of the excitation energy from the photosystem II (PSII) is converted into chemical energy through the linear electron transport.
Salt stress also affects the cell organelles like chloroplast and it is the site for most of photosynthetic processes (PSI and PSII) and generation of reactive oxygen species (ROS) (Nusrat et al., 2014).
Bentazon promotes a safening effect over ALS herbicides due to bentazon to actuate on the photosystem II (PSII) decreasing the ratio of photo assimilates production and translocation, thus, lowering the absorption rate and transportation of the ALS herbicides in the plant's phloem (BAUER et al., 1995b).
Decreased photosynthesis under flooded conditions may be associated with disturbances of photochemical and/or biochemical processes and PSII (photosystem II) is very sensitive to water stress, perhaps due to damage to the oxygen-evolving complex (Wright et al., 2009) or the PSII reaction centers (Slabbert and Kruger, 2011).
DLC films can be produced by a variety of methods [11], which include plasma source ion implantation (PSII) [12, 13].
