Storage of desiccation-tolerant seeds is one of the most effective germplasm conservation strategies; however, several species of tropical and subtropical humid forests have seeds that are sensitive to desiccation, and recalcitrant seeds, making conservation a challenge. Recalcitrant seeds deteriorate during storage due to high respiration rates and metabolic activity, and protocols employing osmoprotective solutions aim to minimize those effects to maintain seed viability for a more extended period. Hancornia speciosa, a fruit tree considered a priority for research in Brazil, is a desiccation-sensitive species. Thus, this study aimed to assess the physiological parameters of viability, vigor, and enzymatic activity of H. speciosa seeds stored in an osmoprotective solution. Germination percentage, water content, electrical conductivity, shoot, root, seedling length, peroxidase activity, and heat-resistant protein concentration were determined for seeds collected during summer and winter harvests. In addition, gene sequences were explored through gene ontology using Blast analysis to identify the biological and molecular processes associated with enzymatic action during storage. Summer-collected seeds performed better in viability and vigor and are recommended for storage in the osmoprotective solution. After being stored in the solution, seeds collected in the winter improved germination and vigor. H. speciosa seeds harvested in the summer or winter and stored in the osmoprotective solution remain viable for up to 90 days. Peroxidase and heat-resistant proteins are active; these enzymes' expression regulation should be investigated in future studies.

“…Benih kakao termasuk benih rekalsitran (Umarani, Kanthaiya Aadhavan, & Mohamed Faisal, 2015), yang harus dikecambahkan segera setelah panen (Lahay, Misrun, & Sipayung, 2018). Benih rekalsitran memiliki sifat sensitif terhadap desikasi (desiccation-sensitive), cepat berkecambah setelah buah matang, menghendaki kelembaban dan suhu tertentu, sensitif terhadap kadar air tinggi dan rendah, serta tidak tahan disimpan lama (Barbedo, Centeno, & Ribeiro, 2013;Berjak & Pammenter, 2013;Pammenter & Berjak, 2014;Umarani et al, 2015;Viana et al, 2020). Terdapat tiga aspek penting yang menyebabkan kerusakan benih rekalsitran selama penyimpanan, yaitu kandungan air biji, tingkat pengeringan, dan suhu penyimpanan (Umarani et al, 2015).…”

<em>During the storage period, cocoa seeds undergo various processes that will affect the content of their food reserves and will have an impact on germination capacity and seeds vigor. The objective of this study is to investigate the changes of biochemical and vigor of cocoa seeds after storage for a maximum of 4 weeks with an interval of 1 week. The experiment was conducted at the Integrated Laboratory and Greenhouse of Balittri, Sukabumi, West Java, from October to December 2019. The completely randomized design with five treatments of seeds storage duration: (a) seeds unstored, (b) seeds stored for 1 week, (c) seeds stored for 2 weeks, (d) seeds stored for 3 weeks, and (e) seeds stored for 4 weeks, and five replications were used in this study. Parameters observed during seed storage were the biochemistry change of seeds and the percentage of germinated seeds, while during seed germination is an indicator of seed vigor. The results showed that storing cocoa seeds for 1-4 weeks decreased the fat content of the seeds, while the free fatty acids, protein, and percentage of germinated seeds increased. Until the 21<sup>st</sup> day after sowing, seed storage increases electrical conductivity but decreases growth rate, maximum growth potential, viability, and hypocotyl length. Seeds stored for one week still good in their vigor (viability of 80%), while seeds stored for 2-4 weeks have decreased their vigor (maximum viability of 54.4%).</em>
