“…Similar results were observed in hydroprimed and KNO 3 -primed sunflower (Helianthus annuus L.) under saline and drought conditions (Kaya et al, 2006). Polyethelene glycol 8000 (PEG8000)-primed soybean (Glycine max L.) showed enhanced seed germination and growth under chilling conditions (Li et al, 2010). However, excess priming may interrupt enzyme activity, resulting in poor germination and abnormal growth (Ajouri et al, 2004;Farooq et al, 2006).…”

Glycinebetaine (GB) seed priming enhances stress tolerance in various plants during the germination and seedling growth stage; however, information regarding turfgrass is limited. In this study, GB at 5 to 50 mm was used to prime seeds of six turfgrass species to evaluate the potential of GB priming in enhancing tolerance to drought, salinity, and sub-optimal temperature during germination. Stress tolerance was determined as relative final germination percentage (FGP) and daily germination percentage (DGP), expressed as percentage of germination under stress conditions compared with the control treatment (i.e., unprimed seeds germinated under non-stress condition) for each species. Daily germination percentage was more sensitive to stress than FGP. Perennial ryegrass (Lolium perenne L.) showed high tolerance to drought, salinity, and chilling temperatures (5 and 10 °C below optimal germination temperature) followed by tall fescue (Festuca arundinacea Schreb.) and creeping bentgrass (Agrostis palustris L.), whereas kentucky bluegrass (Poa pratensis L.), bermudagrass [Cynodon dactylon var. dactylon (L.) Pers.], and zoysiagrass (Zoysia japonica Steud.) were stress-sensitive. Kentucky bluegrass and bermudagrass showed higher germination at 10 mm GB under temperature stress and drought and temperature stresses, respectively; however, other grasses showed limited responses to seed priming. Our results showed that the efficacy of GB priming is plant-, GB concentration-, and stressor-dependent.

“…Moreover, seed priming promoted the ATP and energy levels in rice seeds (Corbineau et al, 1999). Li et al (2010) reported that seed priming increased the stability of the respiratory F I G U R E 7 The malate dehydrogenase activity of Se-primed, SA-primed, and unprimed seeds and seedlings under control temperature and chilling stress.

“…On the aspects of respiration, our previous researches have indicated that seed priming enhanced the respiration rate in rice seeds and seedlings under chilling stress (Hussain et al., 2016; Wang et al., 2016). Meanwhile, the regulating effects of seed priming on energy levels, glycolysis pathways, and the mitochondria development have been reported in peas, soybeans, onions, and tomato (Benamar, Tallon, & Macherel, 2003; Corbineau, Ozbingol, Vinel, & Come, 1999; Li, Yang, Zhang, & Wang, 2010; Sun, Li, Wang, Wu, & Wang, 2011). However, under chilling stress, the influence of seed priming on the respiratory metabolism of rice during seed germination has rarely been explored.…”

“…Priming enhanced germination performance may be considered a result of advanced germination metabolism processes ( Soeda et al, 2005 ) involving more efficient respiratory pathways ( Li et al, 2010 ; Sun et al, 2011 ), enhanced antioxidant activity ( Bailly et al, 1998 , 2000 ; Posmyk et al, 2001 ; Chen and Arora, 2011 ; Yacoubi et al, 2011 ), initiated repairing processes ( Balestrazzi et al, 2011 ; Kibinza et al, 2011 ), and altered phytohormonal balance ( El-Araby et al, 2006 ). Higher expressions of genes and proteins involved in water transport, cell wall modification, cytoskeletal organization, and cell division and increases in protein synthesis potential, post-translational processing capacity, and targeted proteolysis have been linked to the advanced germination of primed seeds ( Gao et al, 1999 ; Gallardo et al, 2001 ; Chen and Arora, 2013 ; Kubala et al, 2015a ).…”

Different Modes of Hydrogen Peroxide Action During Seed Germination

Hydrogen peroxide was initially recognized as a toxic molecule that causes damage at different levels of cell organization and thus losses in cell viability. From the 1990s, the role of hydrogen peroxide as a signaling molecule in plants has also been discussed. The beneficial role of H2O2 as a central hub integrating signaling network in response to biotic and abiotic stress and during developmental processes is now well established. Seed germination is the most pivotal phase of the plant life cycle, affecting plant growth and productivity. The function of hydrogen peroxide in seed germination and seed aging has been illustrated in numerous studies; however, the exact role of this molecule remains unknown. This review evaluates evidence that shows that H2O2 functions as a signaling molecule in seed physiology in accordance with the known biology and biochemistry of H2O2. The importance of crosstalk between hydrogen peroxide and a number of signaling molecules, including plant phytohormones such as abscisic acid, gibberellins, and ethylene, and reactive molecules such as nitric oxide and hydrogen sulfide acting on cell communication and signaling during seed germination, is highlighted. The current study also focuses on the detrimental effects of H2O2 on seed biology, i.e., seed aging that leads to a loss of germination efficiency. The dual nature of hydrogen peroxide as a toxic molecule on one hand and as a signal molecule on the other is made possible through the precise spatial and temporal control of its production and degradation. Levels of hydrogen peroxide in germinating seeds and young seedlings can be modulated via pre-sowing seed priming/conditioning. This rather simple method is shown to be a valuable tool for improving seed quality and for enhancing seed stress tolerance during post-priming germination. In this review, we outline how seed priming/conditioning affects the integrative role of hydrogen peroxide in seed germination and aging.
