“…Malondialdehyde (MDA) is one of the major secondary products of lipid peroxidation of plasma membranes. Despite changes in the content of MDA and/or electrolyte leakage (EL) level in maize tissues in response to a wide range of abiotic stressors (e.g., drought, salinity, waterlogging, low/high temperature, exposure to heavy metals and xenobiotics) have been widely investigated [24,25,26,27], the impact of insect feeding on these oxidative stress markers was not studied in this context. In our study, aphid-induced elevation in MDA content and EL level in both tested maize cultivars was evident.…”

Prior experiments illustrated reactive oxygen species (ROS) overproduction in maize plants infested with bird-cherry-oat (Rhopalosiphum padi L.) aphids. However, there is no available data unveiling the impact of aphids feeding on oxidative damages of crucial macromolecules in maize tissues. Therefore, the purpose of the current study was to evaluate the scale of oxidative damages of genomic DNA, total RNA and mRNA, proteins, and lipids in seedling leaves of two maize genotypes (Złota Karłowa and Waza cvs—susceptible and relatively resistant to the aphids, respectively). The content of oxidized guanosine residues (8-hydroxy-2′-deoxyguanosine; 8-OHdG) in genomic DNA, 8-hydroxyguanosine (8-OHG) in RNA molecules, protein carbonyl groups, total thiols (T-SH), protein-bound thiols (PB-SH), non-protein thiols (NP-SH), malondialdehyde (MDA) and electrolyte leakage (EL) levels in maze plants were determined. In addition, the electrical penetration graphs (EPG) technique was used to monitor and the aphid stylet positioning and feeding modes in the hosts. Maize seedlings were infested with 0 (control), 30 or 60 R. padi adult apterae per plant. Substantial increases in the levels of RNA, protein and lipid oxidation markers in response to aphid herbivory, but no significant oxidative damages of genomic DNA, were found. Alterations in the studied parameters were dependent on maize genotype, insect abundance and infestation time.

“…Under these conditions the stomatal closure results in a reduction of net photosynthesis which is due to the decrease in stomatal conductance, chlorophyll fluorescence and chlorophyll content of leaves [6]. Excess water causes a decline in grain filling and grain weight of corn leading to decreased yield [7]. However, water stress commonly refers to water deficits not excess water.…”

Physiological Responses of Selected Vegetable Crop Species to Water Stress

The frequency of drought periods influences the yield potential of crops under field conditions. The change in morphology and anatomy of plants has been tested during drought stress under controlled conditions but the change in physiological processes has not been adequately studied in separate studies but needs to be reviewed collectively. This review presents the responses of green peas, snap beans, tomatoes and sweet corn to water stress based on their stomatal behaviour, canopy temperature, chlorophyll fluorescence and the chlorophyll content of leaves. These stress markers can be used for screening the drought tolerance of genotypes, the irrigation schedules or prediction of yield.

“…Waterlogging causes membrane lipid peroxidation and damage to organelles like chloroplasts, ultimately resulting in declined chlorophyll concentrations (Irfan et al, 2010;Ren et al, 2016). Decreased chlorophyll formation and damaged photosynthetic apparatus is directly linked to reduced yields in plants under waterlogging, in addition to poor water and nutrient uptake, anoxia and associated anaerobic fermentation that generates much reduced ATP for biochemical processes (Wang et al, 2017;Tian et al, 2019). Factor analysis of variables in the current study shows a strong negative association between irrigation and chlorophyll concentration.…”

Secondary salinization of arable lands, and declining irrigation water resources are major challenges for crop production. We investigated synergistic effects of salinity and irrigation on Phaseolus vulgaris L. in a 4 × 3 factorial experiment with four salinity levels (0, 4, 8 and 12 ppt) coupled with 3 irrigation regimes that reflected a deficit, normal and excess irrigation for the region. Growth and ecophysiological variables were measured, and data submitted to Analyses of variance, Correlation and Factor analyses in the Minitab Version 17 software. Salinity stress decreased height (35.05 to 31.97 cm) as salinity increased from 0 to 8 ppt. Number of leaves, number of branches, number of flowers and fruits as well as fruit mass and harvest index all decreased as salinity stress increased. Plants in the deficit irrigation regime had higher water use efficiency (1.27g/l) and transpiration use efficiency (29.51 g/l) compared to those under higher irrigation regimes. Salinity and water stress effects on yield and plant water relations would significantly impede production of this crop, with significant yield losses of over 400% in higher salinities. Therefore measures to alleviate soil salinity are necessary for enhanced P. vulgaris production in such saline contaminated areas.
