“…The great increase in water use efficiency in inoculated plants compared to noninoculated under half water supply (Table 1) is a definite prove, that mycorrhizal inoculation increased the ability of the root to increase water uptake from the soil (Ruth et al, 2011). Enhancing the water use efficiency by AM inoculation was also found in sweet pepper (Jezdinsky et al, 2012), and in tomato (Bowles et al, 2016). Moreover the higher leaf water potential in inoculated plants (Fig.…”

An open field trial was established to evaluate production, carotenoids, ascorbic acid, and soluble solids of processing tomato inoculated with arbuscular mycorrhizal fungi either at sowing, and reinoculated at transplanting compared to non-treated plants under different soil moisture conditions. Depending on plant water requirement, all treatments induced to three levels of water supply: Full water supply, half water supply, and no water supply by adjusting the water amount. Regardless of mycorrhizal inoculation time and dosage, plants under no water supply conditions faced severe stress and showed no enhancement in growth, yield, and water use efficiency. Mycorrhizal re-inoculation significantly increased the marketable fruit yield, the total biomass, the water use efficiency, and leaf water potential under water shortage conditions in half water supply compared to at sowing inoculated mycorrhizal plants, and non-treated plants as well, suggesting that field mycorrhizal re-inoculation enhances colonized plant water stress avoidance. A strong negative correlation was observed between yield and soluble solid content. Concisely, mycorrhizal re-inoculation was more effective than inoculation at sowing.

“…Comparing the different water supply regimes, water deficit stress decreased the photosynthetic efficiency of photosystem II only in WS 0 . Mycorrhizal inoculation increased substantially photosynthetic efficiency at all water supply levels (Table 2), leading to plant growth improvement [33], and indicating less damage to the photosynthetic apparatus in inoculated plants under water deficiency conditions [34]. According to other authors [35,36] under drought stress conditions would be related to a higher chlorophyll content in inoculated plants.…”

In a field experiment, processing tomato plants inoculated with arbuscular mycorrhizae (AM) and non-inoculated (Control) were supplied with three levels of watering. The AM inoculation significantly increased tomato root colonization regardless of the water supply levels. Under water deficit conditions, AM inoculation significantly increased the biomass production (from 1,189 to 2,062 g plant-1). AM inoculation increased the phosphorus uptake in water deficit supply (from 0.5 to 1.3 g plant-1) and in optimum water supply (from 0.3 to 0.6 g plant-1). Photosynthesis was not affected by irrigation, but mycorrhizal inoculation enhanced the efficiency of photosystem II at all water levels. Inoculated plants accumulated less proline, potassium, and magnesium in shoots in response to water stress. Less organic and inorganic solutes in shoots of inoculated plants were accompanied by higher water use efficiency, better stomatal conductance, and higher leaf water potential. In conclusion, AM inoculation enabled host plants to alleviate moderate water stress, modulating the physiological status of the plants for better water exploitation.

“…Effect of mycorrhizal inoculation on pepper SPAD values, chlorophyll concentration and photosynthetic activity is a controversial topic. Cekic et al (2012) reported positive effect, Haghighi and Barzegar (2017) found that mycorrhization only improved photosynthetic activity, but not chlorophyll content, while in the works of Kaya et al (2009), Jezdinský et al (2012) and Beltrano et al (2013) no effect of mycorrhization was proved. Moreover, Aissa et al (2016) and Bakr et al (2018) found ambiguous SPAD results.…”

In low-cost, unheated greenhouses and tunnels the use of arbuscular mycorrhizal fungi (AMF) and/or grafting can be a less expensive and sustainable solution to combat the adverse effects of monoculture, instead of costly soilless culture. The aim of the present study was to investigate the effects of a commercially available AMF inoculant and grafting on sweet pepper, under circumstances of modelling commercial low-tech greenhouse production. ‘SV9702PP F1’ sweet pepper hybrid was cultivated for seven months in an unheated greenhouse. Beside the control, three treatments were applied: ungrafted AMF treated plants, plants grafted on ‘Bagi F1’ hybrid and AMF treated plus grafted plants. AMF was applied into the planting holes just before transplanting. AMF treatment had positive effects on relative chlorophyll content of leaves (expressed in SPAD value), on plant stand, on plant mass production, on yield and on root colonization rate, despite the high presence of indigenous populations of AMF in the greenhouse soil. With the applied rootstock/scion combination, grafting did not significantly affect the aforementioned parameters. SPAD values were increased by the AMF treatment during periods when smaller doses of nitrogen (less than 0.8 g N per m-2 week-1) were applied. Significant positive correlation was found between root colonization rate and marketable yield. AMF treatment increased the yield by 18% (from 12.43 to 14.74 kg m-2), mostly due to higher number of fruits. Yield increase was mainly realised during the last third of the harvest period, when the applied nutrient doses were low and temperature conditions were suboptimal. ********* In press - Online First.
