Effective microorganisms (EM) are important beneficial fungi and bacteria mixed culture that is used as an inoculant to improve soil quality and health, enhance plant growth, yield, and quality. This study was conducted to evaluate the effect of inoculating various concentration of EM (50, 100 and 200 mL L -1 ) on growth of wheat (Triticum aestivum L.) seedlings, grown under NaCl regime (6 dS m -1 ), including fresh and dry weight, chlorophyll content, maximum fluorescence yield (Fm), variable fluorescence yield (Fv), optimum photosystem II (PSII) quantum yield (QY) and ratio of fluorescence decline in steady state (RFD). Seedlings subjected to salt treatment exhibited significantly 60% and 30% reduction in both fresh in dry weight; respectively, however, when seedlings under saline condition were treated with EM at both 50 and 100 mL -1 , fresh weight was increased two folds. However, for both dry weight and plant length, EM at 100 mL -1 showed the highest significant values compared to salt treated seedlings (40% and 18%, respectively). Salinity treatment reduced significantly chlorophyll content, Fv/Fm and QY, however, the addition of EM at 200 mL L -1 alleviated the effect of salt stress on photosynthetic parameters. The application of both 100 and 200 mL L -1 alleviated the salt effect resulted in a similar chlorophylls content as the control (36.23 and 34.12 SPAD units) respectively. EM application at 200 mL L -1 significantly lowered electrical conductivity from 14.35 to 10.29 dS m -1 of the media. In conclusion, EM can be used to counter act salt effect in soil and improve growth behavior of wheat plants under salinity conditions.

“…Growth attributes, like fresh and dry weight of wheat shoot and root, shoot and root lengths, chlorophyll, and carotenoids were higher in T. reesei inoculated plants (Figures 4-6). Likewise, the rate of photosynthesis and photosynthetic activities are also affected, when plants are grown under stress condition (Kalaji et al 2016). Our results also demonstrated a decrease in Chla and Chlb in control plants with increase in NaCl concentration, while marginal changes have been observed in T. reesei associated plants.…”

The use of plant endophytes to release salt stress is cheap and quick. In this respect, we have isolated an endophytic fungus (Trichoderma reesei) from Solanum surattense that promoted the wheat growth under salt stress. The results showed that the fungal inoculated wheat plants had higher chlorophyll a and b, carotenoids, reduced glutathione (GSH), ascorbate, peroxidase, catalase, weight of plant, flavonoids, total soluble protein, stomatal conductance, transpiration rate, and relative water contents. Also, T. reesei treated plants showed higher IAA, GA, Ca and K, while lower ABA, H 2 O 2 , phenol, sugar, proline, electrical conductivity, malondialdehyde (MDA), Na + and Cl − . The results concluded that the integrative use of T. reesei might help the wheat plants to stand salt stress.

“…It is well documented that salinity induces a negative effect on the quantum yield of PSII electron transport, the energy available for the reaction centers, and the efficiency of oxygen evolving complex (OEC) [51]. In another report, two weeks of salinity stress resulted in a 76% decrease in quantum efficiency of PSII in Arabidopsis plants [54]. We noted that NaCl stress greatly reduced ABS/RC, ET0/RC, and TR0/RC compared to oat plants under non-stress conditions (Mel+W) or plants exposed to salinity after pretreatment with melatonin (Mel+NaCl; Figure 4D).…”

“…The JIP test converts Chl-a fluorescence data to biophysical parameters that quantify the energy flow through PSII [27,53,54]. In addition to evaluating the damage to the acceptor side of PSII, OJIP analysis also calculates the crucial parameters ABS, TR, ET, and RE [27,50].…”

Recent studies have demonstrated melatonin protects various crops against abiotic stresses. However, the effects of melatonin on the photosynthetic apparatus of stressed plants is poorly characterized. We investigated the effects of melatonin pretreatment on photosynthesis and tolerance to salinity stress in Avena sativa (oat) plants. Oat plants were exposed to four treatments (three replicate pots per treatment): well-watered (WW; control); watered with 300 mM salt solution for 10 days (NaCl); pretreated with 100 µM melatonin solution for 7 days then watered normally for 10 days (Mel+W); or pretreated with 100 µM melatonin for 7 days then 300 mM salt for 10 days (Mel+NaCl). Considerable differences in growth parameters, chlorophyll content, stomatal conductance, proline accumulation, lipid peroxidation, electrolyte leakage, and growth parameters were observed between groups. Genes encoding three major antioxidant enzymes were upregulated in the Mel+NaCl group compared to the other groups. Chlorophyll-a fluorescence kinetic analyses revealed that almost all photosynthetic parameters were improved in Mel+NaCl plants compared to the other treatments. Analysis of genes encoding the major extrinsic proteins of photosystem II (PSII) revealed that PsbA, PsbB, PsbC, and PsbD (but not PsbO) were highly upregulated in Mel+NaCl plants compared to the other groups, indicating melatonin positively influenced photosynthesis under control conditions and salt stress. In addition, melatonin upregulated stress-responsive NAC transcription factor genes in plants exposed to salt stress. These findings suggest melatonin pretreatment improves photosynthesis and enhances salt tolerance in oat plants.
