Response of Potato (Solanum Tuberosum L.) Plants to Spraying by Hydrogen Peroxide

Abstract

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.

Boosting Polyamines to Enhance Shoot Regeneration in Potato (Solanum tuberosum L.) Using AgNO3

“…The injurious impact of H 2 O 2 on DNA supports its utilization as a positive control in plant comet assays [61]. In a similar context, Szpunar-Krok et al [62] documented the hazardous effect on chlorophyll content of spaying potato plants with H 2 O 2 . Similarly, the synchronized increase in both H 2 O 2 content and DNA damage manifested by tDNA% was documented in potato plants experiencing salinity stress [63].…”

Effect of Hydrogen Peroxide on the Soil Microbial Community Structure and Growth of Malus hupehensis Rehd. Seedlings under Replant Conditions

“…ARD can lead to stunted tree growth, root rot, reduced fruit production, and then result in tree mortality, ultimately shortening the life span of replanted apple orchards. , The main causes of ARD include increased numbers of harmful fungi and changes in the microbial community structure in the soil under replanting conditions. , This study showed that different concentrations of hydrogen peroxide could promote the replanted seedling growth from the physiological indicators, and both the plant biomass of replanted soil + 3.0% hydrogen peroxide (H2) and replanted soil + 4.5% hydrogen peroxide (H3) treatments were obviously higher than that of CK1. This status was likely due to hydrogen peroxide killing pathogenic fungi in the soil, improving the soil environment for replanting and promoting plant growth . Plant growth cannot be achieved without photosynthesis, and chlorophyll is the main photosensitive pigment for photosynthesis to absorb light energy, which has an important impact on plant growth .…”

Reactive Oxygen, Nitrogen, and Sulfur Species (RONSS) as a Metabolic Cluster for Signaling and Biostimulation of Plants: An Overview

“…In other species, such as Solanum tuberosum , the use of NO donors (SNP, S-nitroso-N-acetylpenicillamine or a mixture of ascorbic acid and NaNO 2 ) demonstrated that NO could protect plants from methylviologen damage produced by herbicides [ 158 ], but could also stimulate phytoalexin accumulation, which can be used as a mechanism of induction of defense against pathogens in plants [ 159 ] or to participate in the wound–healing response of potato leaves by the induction of cell wall glucan callose production [ 160 ]. On the other hand, since H 2 O 2 is relatively stable compared to other ROS molecules such as NO, a recent study demonstrated that foliar spraying of H 2 O 2 at 1% consecutively (7 days) on S. tuberosum caused an increase in the photosynthetic apparatus and antioxidant capacity [ 161 ].…”
