“…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

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.

“…Seeds obtained from these informal, farmer-saved or 'trader-saved' sources have low germination and field emergence. This phenomenon could be attributed to physiological seed dormancy as observed in Solanum melongena (Yogeesha et al, 2006) and Solanum tovum (Cutti and Kulckzynski, 2016), which are close relatives of S. aethiopicum. It could also be due to harvesting and extracting seeds that are not matured.…”

This work aimed at determining the optimum harvest time of African eggplant (Solanum aethiopicum L.) seeds, cv. Oforiwa and cv. Kpando for maximum physiological seed quality under tropical (TCC) and temperate oceanic climatic (TOC) conditions. Fruit morphological metrics such as fruit weight and size were also related to seed physiological quality. Seeds were harvested at different maturation stages from 20 to 82 days after anthesis (DAA). Seed quality was assessed according to moisture content, dry seed weight, seed length, thousand seed weight, percentage germination and emergence. The results indicated that seeds harvested precociously (20 and 34 days after anthesis), did not germinate or recorded very low percentage germination (0-20%). Considering all the fruit morphological traits and seed quality variables measured, the results indicate that maximum seed quality (that is, germination, emergence, seed weight and mean germination time) are obtained from fruits harvested at 76 DAA. The physiological maturity (PM) (maximum seed dry weight) for cv. Oforiwa was attained at 62 DAA while cv. Kpando took 14 days more to reach physiological maturity but coincided with maximum germination at 76 DAA. The results further showed that fruit characteristics such as weight and size are associated with seed physiological quality in African eggplant. It is thus recommended that fruits of African eggplant cv. Oforiwa and cv. Kpando should be harvested at 70 to 76 DAA for maximum seed germination and emergence.
