Special Issue Information

Dear Colleagues,

Seed formation is one of the most important biological innovations in plants and has strongly contributed to the evolutionary success and worldwide supremacy of flowering plants. Via regulatory mechanisms such as dormancy and longevity, seeds control the season-dependent growth of plants, thereby fueling adaptation to (agro)ecological niches and climatic changes. Also, plant seeds carry de novo formed embryos generated via sexual reproduction and thus physically represent the ‘germ’ for novel genetic variability upon which natural or artifical selection can act.

Seeds play a central role in agriculture and breeding. During historical crop domestication, several flowering plants were selected and genetically improved for seed yield, quality, and composition, and this has resulted in a broad range of feed, fodder, and fuel crops, including wheat, rice, brassica, and maize. With the endosperm forming a specialized tissue that nurtures the developing embryo, seeds constitute a rich source of starch, oil, vitamins, and trace elements, which are used in both human and animal diets. Moreover, because of their specific developmental features and overal longevity, plant seeds also form an interesting platform for the synthetic production of valuable biochemicals or compounds (i.e., seeds as biotech factories).

In this Special Issue of Agronomy, we will focus on different aspects of seed biology, seed formation, and seed-related processes in flowering crops. Besides novel insights into the (epi)genetic, molecular, and physiological control of different aspects of seed development (i.e., embryogenesis, endosperm development, dormancy, and germination), this issue will also focus on agronomic practices and (bio)technological innovations that improve seed yield, nutritional composition, or value for crop breeding (i.e., apomixis, haploid induction, etc.). We welcome both fundamental and applied research articles, reviews, communications, and short notes and strongly support the submission of novel methodologies, technological innovations, and mechanistic insights.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Piquin pepper (Capsicum annuum var. glabriusculum) is an important species that supports the economy of rural households; it is part of Mexican gastronomy and it is a highly valuable phytogenetic resource. There has been recent interest in domesticating and exploiting piquin pepper commercially, which has been limited until now due to the low germination rate, and this work had the purpose of promoting germination and determining the physiological capacity of genotypes. Ten piquin pepper genotypes from different geographical origins in Mexico were submitted to 11 pre-germination treatments. A completely randomized experimental design was carried out with arrangement in split-plot. The large plot had the treatments and the small plot had the genotypes. The results showed differences (p < 0.01) among treatments, genotypes, and treatment–genotype interaction. On one hand, treatments gibberellic acid (GA) and mechanical scarification + gibberellic acid (MSGA) increased the physiological potential of genotypes, reaching the highest values of germination speed (GS), germination index (IG) and germination percentage (GP); as well as the lowest values of dead seeds (DS) and hard Seeds (HS). In turn, the genotypes that presented the same condition were G8, G7, and G10. Regarding the interaction, each variable had a different condition. In conclusion, we can increase the physiological potential and solve the dormancy of piquin pepper seed by applying gibberellic acid. Likewise, the best genotypes were G8 and G10. Full article
