“…Compared with stressed plants, AMF-inoculated plants maintained higher contents of chlorophyll pigments. Our results of enhanced chlorophyll contents in AMF-colonized plants are in support of the findings of Hajiboland et al (2010) for Solanum lycopersicum L. and Aroca et al (2013) for lettuce. In pepper, Kaya et al (2009) demonstrated that inoculation of AMF increased chlorophyll content under normal as well as salt-stressed conditions.…”

Present experiments were conducted to assess the response of Panicum turgidum to salinity and possible role of arbuscular mycorrhizal fungi (AMF) in enhancing the salt tolerance. The activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), glutathione reductase (GR) and compatible solutes were increased by salt stress and were further enhanced by AMF inoculation. Hydrogen peroxide and malonaldehyde content increased in salt-stressed plants while a reduction was observed due to AMF inoculation. Salt-stressed plants showed higher activities of pyruvate orthophosphate dikinase (PPDK), phosphoenolpyruvate carboxylase (PEPC) and malate dehydrogenase as compared to control and AMF-inoculated plants. Salt stress caused significant decrease in phosphorous, potassium and calcium uptake but an increase in sodium uptake was observed. AMF alleviate salinityinduced negative impact on the plant growth and nutrient uptake by reducing the oxidative damage through strengthening of the antioxidant system.

, "Using remotely sensed spectral reflectance to indicate leaf photosynthetic efficiency derived from active fluorescence measurements," J. Appl. Remote Sens. 11(2), 026034 (2017), doi: 10.1117/1.JRS.11.026034. Abstract. Chlorophyll fluorescence (ChlF) is an important signature of photosynthesis to evaluate plant response to the environment. We explored an approach to estimate an important leaf ChlF-derived parameter, the intrinsic efficiency of photosystem II photochemistry (F v ∕F m ), using spectral indices calculated from leaf reflectance measured by a hyperspectral radiometer. It is observed that leaf chlorophyll content closely related to F v ∕F m in nonstressed leaves, thus the indices developed for chlorophyll estimation were successfully used to estimate F v ∕F m . For leaves under short-term stress, F v ∕F m dropped dramatically while leaf chlorophyll content remained almost the same. Compared to leaf chlorophyll content, reflectance was more sensitive to F v ∕F m variations. As F v ∕F m decreased, the slope of reflectance in the spectrum range of 700 to 900 nm obviously increased, and the first derivative reflectance in the red edge and infrared (NIR) regions was highly correlated with F v ∕F m . The indices using longwave red edge and NIR reflectance (NDRE 740 and CI 740 ) worked well for F v ∕F m retrieval in both stressed and nonstressed leaves with the coefficients of determination (R 2 ) above 0.72 and normalized root-meansquare errors below 0.16. Note that the relationships NDRE 740 and CI 740 versus F v ∕F m were significantly different between nonstressed and stressed leaves, which may give a good implication to detect short-term stress occurrence.

“…Reduction in morphological parameters may be due to the inhibition of cell division and reduced rate of cell elongation exerted by the high salinity levels (Aroca et al, 2013;Ahanger et al, 2014;Wu et al, 2014). Inoculation of AMF enhanced the growth parameters and also mitigated the reduction induced by salinity to some extent.…”

“…AMF colonization brings morphological, nutritional and physiological changes and has also been reported to enhance resistance of plants to abiotic stresses (Hameed et al, 2014). AMF modifies root architecture so that roots explore much water and nutrients (Aroca et al, 2013;Ahanger et al, 2014;Wu et al, 2014). Mycorrhizal inoculation not only affects root morphology but also physiological status in host plants (Alqarawi et al, 2014a;Hashem et al, 2014a).…”

The aim of present study was to examine the effect of arbuscular mycorrhizal fungi (AMF) on the growth, lipid peroxidation, antioxidant enzyme activity and some key physio-biochemical attributes in cowpea (Vigna unguiculata [L.] Walp.) subjected to salt stress. Salt stress (200 mM NaCl) reduced growth, biomass, relative water content and chlorophyll pigment content in cowpea leaves. AMF ameliorated the negative impact of salinity on the growth parameters studied. The activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), peroxidase (POD) and glutathione reductase (GR) enhanced under salt stress and AMF inoculation further enhanced their activity, thus strengthening the plant's defense system. Proline content increased in salt stressed plants as well as AMF-inoculated plants providing efficient protection against salt stress. Besides this AMF also increased uptake of mineral elements which have direct impact on the osmoregulation of the plants. The present study shows that AMF possesses the potential to enhance salt tolerance of cowpea.
