“…NO is also able to reduce the effects of seed aging (Pereira et al, 2010) and increase tolerance to various abiotic stresses, such as water stress, salt stress, and stress from heavy metals (Silva et al, 2015;Kaiser et al, 2016;Pires et al, 2016). Oxidative stress, brought about by increase in concentration of superoxide, hydrogen peroxide, and alkyl peroxides, can be combatted by NO, since it has antioxidant properties (Silva et al, 2015;Pires et al, 2016).…”

“…In the presence of transition metals, such as iron, copper, or zinc, the NO can interact to form metal-nitrosyl complexes. These complexes may be related to the regulatory effects of the transcription factors of NO and certain enzymes (Silva et al, 2015). Tolerance is generated by stimulation of the activity of one or more enzymes of the antioxidant system, such as superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase, reducing the action of reactive oxygen species (ROSs) (Pires et al, 2016).…”

The germination response of seeds under artificial stress conditions is a tool for better understanding of the survival and adaptation ability of species under natural stress conditions. The aims of this study were to evaluate the protective effect of nitric oxide during germination as well as seed vigor and seedling development of Eucalyptus urophylla under salt stress conditions. The experimental design was completely randomized, with five replications, in a 3 × 3 + 1 factorial arrangement, with three priming factors [water, sodium nitroprusside (SNP), and potassium nitrate (KNO3)], three germination conditions (distilled water, and the water potentials of -0.6 and -1.2 MPa), and an additional control treatment (unprimed seeds). The following determinations were made: germination count at seven and fourteen days, germination speed index, primary root length, shoot length, and total length. SNP protects seeds, leading to a higher percentage of germination, as well as greater root growth and total seedling size, whereas KNO3 is not effective in protecting seeds that suffer from salt stress, which affects their physiological and morphological characteristics. E. urophylla seeds are sensitive to salt stress, and physiological priming with SNP leads to an increase in the percentage of germination, vigor, and seedling development under salinity conditions.

“…Each treatment was primed in a single Erlenmeyer flask, without replications. The priming solutions used were distilled water (water), 0.2% potassium nitrate solution (KNO 3 ) (Cardoso et al, 2014;Cardoso et al, 2015), 0.5 mmol.L −1 spermidine solution (SPER) (Hussain et al, 2015;Lopes et al, 2018), 50 mg.L −1 pure gibberellin solution (GB) (Batista et al, 2015;Cardoso et al, 2015), and 0.10 mmol.L −1 sodium nitroprusside solution (SNP) (Ataíde et al, 2015;Silva et al, 2015;Faraji et al, 2018). The seeds used as a control were not primed.…”

Protective action of priming agents on Urochloa brizantha seeds under water restriction and salinity conditions

et al. 2021

Analyses of germination of seeds under artificial stress conditions are tools for a better understanding of the survival and adaptation capacity of species under natural stress conditions. Therefore, the aim of this study was to evaluate the effect of priming on seed germination, on breaking of dormancy, and on the length of Urochloa brizantha seedlings under water restriction and salt stress conditions. A completely randomized experimental design was used with four replications in a 3 × 6 factorial arrangement consisting of 3 germination conditions (water, water restriction with PEG, and salinity with NaCl) and 6 treatments [five priming solutions (distilled water, potassium nitrate, spermidine, gibberellin, and sodium nitroprusside) and a control (unprimed seeds)]. The following determinations were made: seed moisture content after priming (before drying) and after drying the seeds, germination test at seven and twenty-one days after sowing, germination speed index, viability by the tetrazolium test of the seeds remaining from the germination test, and seedling length. Priming is effective in minimizing the negative effects of water restriction and salinity. Use of sodium nitroprusside as a priming solution results in a lower percentage of dormant seeds and greater germination, vigor, and plant development.

“…Treatment with (200 µM) Sodium nitroprusside+ (100 µM) sodium ferrocyanide showed an average of 0.96 providing a 14.14% reduction in the qL parameter (quenching related to photosynthesis photoinhibition) when compared to the control treatment (deionized water), which obtained an average of 1.12., As shown in Table 5. ISSN 2166-0379 2020 According to Silva (2015), NO can react quickly with O2.-producing peroxynitrite (ONOO-) (Popova & Tuan, 2010), being able to act in increasing the synthesis and / or activity of antioxidant enzymes, such as ascorbate peroxidases (DEL RIO, 2015), resulting in the activation of defense mechanisms (Saxena & Shekhawa, 2013).…”

The aim of this work was to evaluate the attenuating effect of the nitric oxide donor (sodium nitroprusside-NPS) on the ecophysiological responses of corn plants (Zea mays L.) submitted to copper toxicity. The corn seeds of the K9606 VIP3 variety were soaked for 48 hours in Germitest with solution containing treatment with sodium nitroprusside Na2 [Fe (CN) 5 NO] 2H2O (0, 200 and 300µM), sodium ferrocyanide Na4Fe (CN) 6 ( 300, 100 and 0 µM) respectively and deionized water (control), sown in buckets with 15 kg of soil incubated for 50 days containing copper concentrations CuSO4.5H2O (0, 60 and 200 mg kg-1). The design consisted of randomized blocks with 12 treatments and 4 repetitions, making a total of 48 plants. in ecophysiological variables: height, leaf area and number of leaves, stem diameter increased by 32, 66% and 11.29% in the treatments with 60 mg kg-1 of copper and 200 mg kg-1 of copper, respectively. There was no effect of treatments on the chlorophyll content measured by the SPAD index and gas exchange. The chlorophyll a fluorescence variables indicate that the concentration of 200 mg kg-1 of copper caused damage to the structure of the PS II reaction center complexes and indicate a slightly protective effect of nitric oxide-NO present in sodium nitroprusside and cyanide present in sodium ferrocyanide, reflecting a smooth functioning of the maximum activity of photosystem II and the electron transport chain.
