“…It was also reported that the best treatment to seed of muskmelon for germination and emergence at low temperature was 2.5% KNO 3 for 16 h in dark [33]. Demir et al [34] reported that GA 3 and KNO 3 treatments influenced on eggplant seed germination and rate of germination respect comparing that of the control. In addition, Brocklehurst et al [35] stated that PEG gave suitable results for different vegetable species such as onion, leek, and celery and KH 2 PO 4 had effect of reducing in percentage germination and emergence in leek and celery.…”

The effects of different priming treatments and priming durations on germination percentage at different temperatures in parsley seeds were studied. The seeds were treated for 2, 4, 6 and 8 days with the PEG 6000 (–0.5 MPa, –1.0 MPa and –1.5 MPa), KNO3 (0.30 mol/L and 0.35 mol/L), Mannitol (0.50 mol/L and 0.60 mol/L) and hydropriming (12h, 24h, 36h and 48h) and unprimed (control). Germination studies were made at 5, 10, 15, 20 and 25°C. Percentage of germination at different temperatures was significantly affected by priming treatments. Hydropriming (12h, 24h and 36 h) and mannitol 0.60 mol/L at 2 day generally had the highest germination percentages. In general, the highest germination percentage with priming was determined at 10°C. It may be said that seed priming treatments increased seed germination percentage at both low and high temperatures. The highest germination percentages were observed in both hydropriming and mannitol treatments as compared with PEG and KNO3 treatments. The PEG and KNO3 (2 and 4 days) treatments were better than unprimed treatment in all of the temperatures

“…GAs are plant growth hormones and have positive effects on seed germination, stem elongation, flowering initiation, and flower and fruit development [ 66 , 67 ]. GAs regulate plant growth and development during the entire life cycle of plants [ 68 ]. Demir et al [ 68 ] reported that the application of GA 3 significantly increased the germination speed of eggplant ( Solanum melongena ) seeds.…”

Plants are often exposed to abiotic stresses such as drought, salinity, heat, cold, and heavy metals that induce complex responses, which result in reduced growth as well as crop yield. Phytohormones are well known for their regulatory role in plant growth and development, and they serve as important chemical messengers, allowing plants to function during exposure to various stresses. Seed priming is a physiological technique involving seed hydration and drying to improve metabolic processes prior to germination, thereby increasing the percentage and rate of germination and improving seedling growth and crop yield under normal and various biotic and abiotic stresses. Seed priming allows plants to obtain an enhanced capacity for rapidly and effectively combating different stresses. Thus, seed priming with phytohormones has emerged as an important tool for mitigating the effects of abiotic stress. Therefore, this review discusses the potential role of priming with phytohormones to mitigate the harmful effects of abiotic stresses, possible mechanisms for how mitigation is accomplished, and roles of priming on the enhancement of crop production.

“…Seed vigor and germination profiles are among the standardized descriptors used to recommend genotypes for breeding ( Taher et al, 2017 ). Dormancy, low seed germination rate and uniformity, documented in eggplant CWRs ( Demir et al, 1994 ; Adebola and Afolayan, 2006 ; Taab and Andersson, 2009 ), strongly delay or prevent their exploitation in breeding programs or their use as rootstocks. Low-cost, pre-sowing treatments (“seed priming”) can be used to improve germination.…”

“…To date, there are reports describing the benefits and drawbacks of this technology applied to eggplant ( Demir et al, 1994 ; Gomes et al, 2012 ; Gonzales, 2015 ; Neto et al, 2017 ; Ali et al, 2019 ) and its CWRs, S. torvum Swartz 1788 (turkey berry) ( Ranil et al, 2015 ; Cutti and Kulckzynski, 2016 ; Ozden and Demit, 2016 ; Sarathkumar et al, 2017 ), S. macrocarpon , S. aethiopicum , and S. incanum ( Gisbert et al, 2011 ). However, much more studies are still necessary to cover the huge biodiversity of this horticultural crop and its wild relatives.…”

Hydropriming Applied on Fast Germinating Solanum villosum Miller Seeds: Impact on Pre-germinative Metabolism

et al. 2021

Seed priming can circumvent poor germination rate and uniformity, frequently reported in eggplant (Solanum melongena L.) and its crop wild relatives (CWRs). However, there is still a gap of knowledge on how these treatments impact the pre-germinative metabolism in a genotype- and/or species-dependent manner. The CWR Solanum villosum Miller (hairy nightshade) investigated in this study showed a quite unique profile of fast germination. Although this accelerated germination profile would not apparently require further improvement, we wanted to test whether priming would still be able to impact the pre-germinative metabolism, eventually disclosing the predominant contribution of specific antioxidant components. Hydropriming followed by dry-back resulted in synchronized germination, as revealed by the lowest MGR (Mean Germination Rate) and U (Uncertainty) values, compared to unprimed seeds. No significant changes in ROS (reactive oxygen species) were observed throughout the treatment. Increased tocopherols levels were detected at 2 h of hydropriming whereas, overall, a low lipid peroxidation was evidenced by the malondialdehyde (MDA) assay. Hydropriming resulted in enhanced accumulation of the naturally occurring antioxidant phenolic compounds chlorogenic acid and iso-orientin, found in the dry seeds and ex novo accumulation of rutin. The dynamic changes of the pre-germinative metabolism induced by hydropriming are discussed in view of future applications that might boost the use of eggplant CWRs for breeding, upon upgrade mediated by seed technology.
