“…Increasing either photosynthetic efficiency or total plant photosynthetic capacity (delaying leaf senescence) results in the enhanced production of photoassimilates (van Camp 2005). It has been established that H 2 O 2 affects the net photosynthetic rate and the related attributes in plants (Fariduddin et al 2014, Khan et al 2015, Hasan et al 2016. Khandaker et al (2012) also noted that exogenous application of H 2 O 2 increased photosynthetic rates and dry matter content of the leaves in wax apple under field conditions.…”

“…It has been shown that presown seed primed with H2O2 improved seed quality, resulting in better germination performance and greater vigour, while moderately abolishing aging effects on seeds (Wojtyla et al 2016). Recently, Hasan et al (2016) reported that foliar application of H 2 O 2 increased growth parameters in Vigna unguiculata. Low concentration of H 2 O 2 positively affected the adventitious root growth of marigold and sweet potato seedlings (Deng et al 2012, Liao et al 2012.…”

“…It plays an important role in plant cell wall reinforcement (cross-linking of cell wall structural proteins, lignification), production of phytoalexin, and resistance augmentation against diverse stresses Tuteja 2010, Ahmad 2014). H2O2 is a key regulator in a broad range of physiological and biological processes such as germination and seedling growth (Wahid et al 2008), photosynthesis (Noctor and Foyer 1998, Fariduddin et al 2014, Khan et al 2015, Hasan et al 2016, stomatal movement, cell growth, and development (Deng et al 2012), antioxidant systems (Khan et al 2015, Hasan et al 2016, and senescence (Peng et al 2005). Therefore, it has been reported that the endogenous content of H 2 O 2 depends on its production rates and utilization by antioxidant systems (Hung et al 2005, Terzi et al 2014.…”

In plants, hydrogen peroxide (H 2 O 2) acts as a signalling molecule that facilitates various biochemical and physiological processes. H 2 O 2 is a versatile molecule, involved in several cellular processes both under stress and stress-free conditions. In regulating plant metabolism under stress conditions, exogenous application of H 2 O 2 also plays a pivotal role which is manifested in improved growth, photosynthetic capacity, and antioxidant protection. Abiotic stress is an inevitable environmental factor that extensively affects and reduces growth, quality, yield, and productivity of plants. Several signalling pathways involved in H 2 O 2-mediated stress and defense responses have been extensively studied and there is ample scope of additional research that could further clarify the mechanism and modulating factors which regulate these pathways. An attempt has been made to dissect the role of H 2 O 2 under low temperature stress and how it affects plant growth and development, photosynthetic capacity, regulation of antioxidant system, and signalling.

“…In the maize grown under water-deficit conditions, after seed pretreatment with H 2 O 2 , enhanced the activity of antioxidant enzymes in seedlings was observed as well. An increase activity of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) after using H 2 O 2 was found in maize [62] and in cowpea [63]. Ahmad et al [58] watched decline in photosynthetic pigments and increase in the concentration of proteins, H 2 O 2 , malondialdehyde (MDA), and ascorbic acid (AsA).…”

The biocidal properties of hydrogen peroxide (H2O2) could be used in plant protection. However, the effects of H2O2 foliar spraying on the performance of the potato photosynthetic apparatus are still unclear. A pot experiment was conducted to investigate the effect of foliar spraying, which was done twice, with various H2O2 concentrations (1, 3, 6, 12, and 18%) on the potato photosynthetic apparatus efficiency and antioxidant capacity. The measurements were taken four times: on the first and seventh day after each application. Foliar spraying with 1% H2O2 concentration was the most stimulating for the course of physiological processes in leaves. Further increased doses of H2O2 enhanced stress in plants which is manifested by a decrease in pigment levels, photosynthetic attributes, antioxidant capacity in leaves, and fresh mass above-ground parts of potato plants. The intensive effect of spraying was particularly observed on the first day after application, while later, the activity of the photosynthetic apparatus and antioxidant capacity increased. The study provides information that foliar spraying with 1% H2O2 can be taken into account in further research on the development of a potato plant protection methods.

“…Among these alternatives, exogenous application of hydrogen peroxide (H 2 O 2 ) has proved promising in the mitigation of effects caused by salt stress on crops (CARVALHO et al, 2011;GONDIM et al, 2013;OLIVEIRA, 2016). In this context, several authors have conducted studies with rice (Oryza sativa) (UCHIDA et al, 2002), corn (Zea mays L.) (AZEVEDO NETO et al, 2005;SILVA et al, 2016), wheat (Triticum) (WAHID et al, 2007), orange (Citrus sinensis L.) (TANOU et al, 2009) and cowpea (Vigna unguiculata) (HASAN et al, 2016) and observed that hydrogen peroxide acts in the acclimation of plants to salt stress. However, for the soursop crop there is no information on the use of hydrogen peroxide for its acclimation to salt stress conditions.…”

The Brazilian Northeast region provides favorable conditions for the exploitation of several crops, but the high salt concentration in irrigation water constitutes a limiting factor for production in most cases. In this context, this study aimed to evaluate the emergence, growth and partition of photoassimilates in soursop seedlings, cv. ‘Morada Nova’, subjected to irrigation with water of increasing salinity levels and to exogenous application of hydrogen peroxide. The study was carried out in plastic bags under greenhouse conditions, using a sandy loam Regolithic Neosol, in the municipality of Campina Grande, PB, Brazil. Treatments were distributed in randomized blocks, in a 5 x 5 factorial arrangement, relative to five levels of irrigation water electrical conductivity - ECw (0.7, 1.4, 2.1, 2.8 and 3.5 dS m-1) and five concentrations of hydrogen peroxide - H2O2 (0, 25, 50, 75 and 100 µM), with four replicates and three plants per plot. Increasing salt concentration compromised all variables analyzed and leaf area was most sensitive. As irrigation water electrical conductivity increased, the deleterious effects of water salinity on the emergence percentage, emergence speed index, stem diameter and leaf area were attenuated by the exogenous application of hydrogen peroxide, with highest efficiency at the concentration of 50 µM. Hydrogen peroxide concentrations above 38 µM inhibited the specific leaf area of soursop, cv. ‘Morada Nova’.
