“…Para sementes sensíveis à dessecação, a utilização de inibidores endógenos, como ABA, a regulação da mobilização da água na semente com soluções osmóticas e os estresses hídricos também se mostraram favoráveis para a conservação. Outra opção seria a desidratação parcial, ou seja, a secagem até atingir o menor grau de umidade suportável para a semente (Andréo et al 2006, Bonjovani & Barbedo 2008, Chandra et al 2019.…”

RESUMO O elevado metabolismo de sementes sensíveis à dessecação (recalcitrantes) de Inga vera Willd. subsp. affinis (DC.) T.D.Pennington é um dos principais fatores que dificultam a manutenção da viabilidade fisiológica das sementes durante o armazenamento. Devido à falta de informações sobre o metabolismo respiratório dessas sementes em diferentes condições de estresse, este estudo teve como objetivo determinar as taxas de respiração de embriões com diferentes conteúdos de água e em diferentes temperaturas após a aplicação dos tratamentos com ABA e PEG. Os resultados mostraram altos níveis de respiração e presença de reações oxidativas. O ABA mostrou poucos efeitos, mas a respiração e os processos oxidativos foram diminuídos pela secagem leve e pelo tratamento com PEG. Portanto, a redução da temperatura de armazenamento é eficiente na redução do metabolismo, permitindo ampliar o armazenamento, mas a escolha do estádio de maturação é decisiva para melhor conservar os embriões de Inga vera.

“…Berjak et al, 1989). However, under these conditions, recalcitrant seeds still initiate germination-associated events, culminating in seed death (Berjak et al, 1989;Pammenter et al, 1994;Chandra et al, 2019). Storage at temperatures lower than ambient has been shown to postpone the onset of germination in recalcitrant seeds by slowing down the metabolic rate (e.g.…”

Access to plant genetic resources is fundamental to the development of more resilient and nutritious crops. The efficient and effective conservation of plant genetic resources is therefore key to ensuring global food security. There are more than 1750 genebanks around the world, storing various types of plant germplasm including tissue cultures, seeds, embryos and pollen. This chapter describes some of the recent applications of science and technology to improve the management of genebank collections of orthodox seeds, not least through the introduction of automation. In addition, the chapter looks at how routine cryopreservation procedures are now possible for many species, and how storage procedures for recalcitrant-seeded and vegetatively propagated species continue to evolve given the challenges they present in terms of long term ex situ germplasm conservation.

“…Hasil analisis regresi menunjukkan bahwa semakin lama periode penyimpanan benih, maka semakin tinggi daya hantar listrik (18,64 us/g/minggu), sebaliknya semakin menurun kecepatan tumbuh (0,89%/etmal/minggu), potensi tumbuh maksimum (9,46%/minggu), viabilitas (12,18%/minggu), dan panjang hipokotil (0,34cm/minggu) (Gambar 7). Meningkatnya daya hantar listrik, dan menurunnya kecepatan tumbuh, potensi tumbuh maksimum, dan viabilitas benih yang sejalan dengan semakin lamanya penyimpanan benih, sejalan dengan hasil penelitian lain yang dilakukan pada berbagai jenis benih rekalsitran seperti benih kakao, pinus Brasil, jabon putih, kacang gude, guanandi, kapas, tengkawang, kedelai, beberapa benih tanaman hutan tropis, trema, dan benih tanaman pupuk hijau "tare" (Baharudin, Ilyas, Suhartanto, & Purwantara, 2010;Araldi & Coelho, 2015;Yuniarti & Nurhasybi, 2015;Manjunatha, Vasudevan, Umesha, & Sravani, 2016;Nery, Prudente, Alvarenga, Paiva, & Nery, 2016;Oliveira et al, 2016;Rohandi & Widyani, 2016;Shibata & Coelho, 2016;Becerra-Vázquez, Sánchez-Nieto, Coates, Flores-Ortiz, & Orozco-Segovia, 2018;Yuniarti, Syamsuwida, & Kurniaty, 2018;Chandra, Sershen, Varghese, & Keshavkant, 2019;Mokhtari & Kizilsimsek, 2019).…”

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 21st 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%).
