“…Cu application caused a significant decrease in soluble protein level which is in accordance with the results of Qi et al (2006) and Yadav & Mohanpuria (2009). This reduction might be attributable to either reduced protein synthesis (Guzel & Terzi, 2013), enhanced protein hydrolysis (Kasim, 2005),or inhibition of nitrate reductase in the cytoplasm and nitrite reductase in the plastids (Lin et al, 2008 andAgami, 2016).…”

T HE EFFECT of CuSO 4 stress on some growth parameters and some metabolites in 14-dayold Vicia faba seedlings was studied. Irrigation with 150 mM CuSO 4 resulted in remarkable reduction in root length, shoot height, fresh and dry weights of root and shoot, leaf area and photosynthetic pigments (Chl a, Chl b and carotenoids), while it raised Chl a/b ratio. Total soluble carbohydrates and protein contents were significantly depleted under Cu treatment. The ameliorative role of seed priming with different concentrations of yeast extract (25, 50, or 100 %), IAA (0.1, 0.3, 0.5 mM), or the green-synthesized Nano zinc oxide with average size 61 (nm) prepared from leaf extract of Coriandrum sativum (10, 50, 100 ppm) for different periods (6 and10h for yeast and IAA, 3 and 6h for Nano ZnO were studied. Results revealed that seed priming with 50% yeast or 0.1 mM IAA for 10h showed a remarkable increase in the measured growth criteria, chla, chl b, soluble carbohydrates and proteins but diminished chl a/b ratio compared with the Cu stress treatment. Seed priming with 100 ppm Nano ZnO for 6 h exhibited the most effective treatment in mitigating the harmful effects of Cu stress on growth criteria, Chla, Chl b, soluble carbohydrates and proteins.

“…Then, when cooled, the volume in the tube was completed with ultrapure water up to 25 mL, and readings were done in a flame photometer. Proline concentration was determined through the methodology by Bates et al (1973), as described by Guzel & Terzi (2013). The lipid peroxidation level was determined by estimating malondialdehyde (MDA) content according to Cakmak & Hosrt (1991).…”

This study aimed to investigate the effect of salinity on growth parameters and oxidative stress markers in leaves and roots of two sweet corn genotypes: BR 427III, obtained from Embrapa Milho e Sorgo, and Tropical Plus®, a commercial hybrid. The genotypes were kept in 15-L pots with typical dystrophic red latosol soil, and irrigated with NaCl solution (0, 25, 50, 100, 150 and 300 mM). At 105 days after planting, the samples were collected, immediately frozen in liquid nitrogen, and stored at -80 ºC for posterior analyses. After this period, it was verified that, while NaCl concentration increased, there was a decrease in leaf and root fresh and dry masses as well as in shot and root lengths of both evaluated genotypes. A decrease in the stem diameter of BR427III genotype plants and in the chlorophyll index of both genotypes was observed. Sodium accumulation in the root and leaves increased according to the stress severity; however, potassium content reduced in both roots and leaves. Proline content increased significantly in the leaves of both evaluated genotypes when exposed to higher concentrations of NaCl. On the other hand, malondialdehyde content decreased in leaves and root of Tropical Plus genotype, where an increase in electrolyte overflow from membrane damage caused by stress severity was observed.

“…The soluble sugar content of the root bleeding sap was determined with the anthrone-sulfuric acid method described by Quan et al [38]. The soluble protein content was measured with the Coomassie Brilliant Blue G-250 method described by Guzel and Terzi [39]. The free amino acid content was determined using the ninhydrin colorimetry method according to Sun et al [40].…”

Root function plays a vital role in maintaining crop production. However, the role of deep roots in yield production and their effects on photosynthetic performance in sorghum remain unclear. This study aimed to provide theoretical supports for establishing highly efficient root systems of sorghum to achieve more yield under certain conditions. In this study, two sorghum (Sorghum bicolor L. Moench) cultivars, Jiza127 and Jiza305, were cultivated in soil columns as experimental materials. Three treatments (no roots removed, CK; roots removed at 30 cm underground, R30; roots removed at 60 cm underground, R60) were carried out under drought conditions during the filling stage. The root bleeding intensity, endogenous substances in the root bleeding sap, photosynthetic characteristics, dry matter accumulation, and yield were measured. The results showed that R30 and R60 significantly reduced yield in both sorghum cultivars, and the effect of R30 on yield was greater than that of R60. The contributions of roots below 30 cm to the yield of both sorghum hybrids were notably higher than those below 60 cm. R30 significantly reduced the dry matter weights (DMWs) of leaves, stems, sheaths, and panicles. R60 significantly reduced the DMW of panicles but had no significant effect on the DMWs of leaves and stems. R30 significantly reduced the photosynthetic level and PSII reaction center activity; however, the effect of R60 was not significant. Although both R30 and R60 significantly reduced root activity and the soluble sugar, amino acid, gibberellin (GA3), and abscisic acid (ABA) contents of the root bleeding sap, some of the above indicators in R60 were significantly higher than those in R30 during the filling stage, indicating that the deeper roots (below 30 cm) had a critical regulatory effect on the physiological processes of the aerial parts in sorghum, which resulted in a stronger effect on yield, especially under drought conditions. In brief, the deep roots of sorghum played a key role in yield production, but the roots in different soil depths regulated yield production in different ways. Our results indicate that deep roots of sorghum deserve consideration as a potential trait for yield improvement especially under drought conditions.
