“…10-12), but susceptible variety showed more reduction of all three enzymes than tolerant over control at 6mM aluminum treatment, But AA and SA treatment improved the activity and proved that they alleviate Al toxicity, So both primed varieties performed better and showed less decreased enzyme Invertase, Sucrose synthase and α-Amylase activity at 6mM Aluminum concentration. Similar results were observed in tomato (Simon et al, 1994); barley (Mona, 2008); rice (Muthukumaran and Vijaya, 2014) against aluminum toxicity. Graph.14 Protease activity (µM g-1FW) in RD2052 and RD2552 Barley varieties (unprimed and primed with AA and SA) germinated under different concentrations of Aluminum at pH4…”

“…In effect, decreases in both total chlorophyll (chl) content and photosynthetic rates have been reported for some species (2,6). Both stomatal and non-stomatal factors have been invoked to account for Al-depressed photosynthesis (5,7,8). Moustakas et al (8), for instance, pointed out that Al-stress inhibited photosynthesis as a result of partial inhibition of photosynthetic electron transport in photosystem (PS) II and closure of PSII reaction centers; in addition, chloroplast elemental loss and concurrent 822 PEIXOTO, DA MATTA, AND CAMBRAIA intrathylakoid acidification were also observed.…”

This work focused on the effects of aluminum (Al) stress on photosynthetic apparatus using Al-tolerant and sensitive cultivars of sorghum (Sorghum bicolor (L.) Moench). Plants were grown in Clark's nutrient solution aerated continuously and adjusted daily to pH 4.0 and containing two Al concentrations (0 and 185 mmol m À 3 ) supplied as Al 2 (SO 4 ) 3 Á 18H 2 O. Measurements were performed on recently expanded leaves from the eighth to sixteenth day after imposing Al treatments. In general, chloroplastidic pigment concentration, chlorophyll fluorescence parameters, and photosynthetic rates were initially affected by Al stress to a greater extent in the Al-tolerant cultivar than in the susceptible cultivar. However, the Al-tolerant genotype JOURNAL OF PLANT NUTRITION, 25(4), 821-832 (2002) 821 seemed to cope with high Al via progressive, sustained decreases in initial chlorophyll fluorescence and increases in chlorophyll a=b ratio, photosystem II photochemical efficiency, net carbon assimilation rate, and photosynthetic oxygen evolution. In contrast, the Al-sensitive cultivar did not show any apparent acclimation response to high Al application. The results suggest that the harmful effects of Al on photosynthesis might be partially alleviated through time-dependent mechanisms, particularly in the Al-tolerant sorghum cultivar.

“…Al inhibits root growth and elongation by different mechanisms, including Al interactions within symplast, plasma membrane and cell wall (Kochian 1995, Pineros and Kochian 2001, Yang et al 2008. Several studies revealed that Al stress decreased net photosynthetic rate (PN) and chlorophyll (Chl) content in tomato (Simon et al 1994), maize (Lidon et al 1999, Mihailovic et al 2008, Citrus spp. , Chen et al 2005a, and soybean ).…”

The effect of aluminum and chromium on two barley genotypes differing in Al tolerance was studied in a hydroponic experiment. Al stress decreased plant growth, biomass production, chlorophyll content and photosynthetic efficiency determined as variable to maximum chlorophyll fluorescence ratio (F v /F m ), net photosynthetic rate (P N ), intercellular CO 2 concentration (c i ), stomatal conductance (g s ) and transpiration rate (E) less in an Al-tolerant genotype Gebeina than in an Al-sensitive genotype Shang 70-119. Cr stress also caused marked reduction in growth and photosynthetic traits in barley plants. Higher reduction was observed at pH 4.0 as compared to pH 6.5. Combined stress of Cr and Al, caused further reduction in growth and photosynthetic parameters.
