“…On the other hand, recalcitrant seeds cannot be dried to a MC less than 15% to 30%, depending on species, or stored at subzero temperatures without losing viability. Intermediate seeds can tolerate drying to 7% to 12% MC, but further drying and storage at subzero temperatures; e.g., -20°C, reduces seed longevity (Chen et al, 2008;Hong and Ellis, 1996). On the basis of the tolerance of mature seeds to desiccation and subzero temperatures, seeds of kapok are orthodox seeds (Hong and Ellis, 1996).…”

Kapok (Bombax ceiba) is a deciduous tree that can grow in the dry-hot valley of southwestern China where its natural regeneration by seedlings is difficult. As mature fruit split open and seeds disperse by wind, it is difficult to collect fully mature seeds. The effects of seed moisture content (MC) and storage temperatures on seed germination of dark-brown seeds collected from split fruit and light-brown seeds collected ≈10–15 days earlier than the time of fruit split were studied to determine the effective germplasm preservation via the seeds. Dark-brown mature seeds could tolerate desiccation to less than 5% MC and could tolerate −20 and −80 °C. Seeds of kapok showed orthodox storage behavior. They can be stored at subzero temperatures with low MC for a long time. For light-brown seeds, germination percentage (GP), germination index (GI), seedling fresh weight (SFW), and vigor index (VI) decreased significantly after seed desiccation. Germination percentage of light-brown seeds with different MC increased to a different extent after being stored at different temperatures for 1 year (76% to 99%), compared with the fresh seeds (73%). Storing fresh seeds at 4 °C was most favorable to keep seed viability and seed vigor of light-brown seeds. Seed collection could be done several days earlier than the time of fruit burst to ensure increased quantity of collected seeds.

“…The mode of action of hydrogen peroxide in the promotion of germination is unclear but may involve the scarification of the seedcoat [27] or oxidation of germination inhibitors [29]. Ogawa and Iwabuchi [29] suggested that the second mechanism is responsible for promoting germination of Z. elegans seeds.…”

Abstract:The decrease of seed quality during storage is strongly associated with damage caused by free radicals. Some compounds of natural origin, known due to their antioxidative and antifungal properties, may be potentially used in organic production for seed treatment as an alternative to pesticides. The aim of the experiment was to study an ability of hydrogen peroxide and organic acid to improve germination, vigour and health of non-deteriorated and deteriorated zinnia seeds. Two seed samples, cv. Illumination and Orys, varying in initial infestation with fungi were tested. For deterioration seeds were kept at 30°C and 80% RH for 30 days. Seed quality tests were performed before and after deterioration for controls and seeds soaked in 3.0% hydrogen peroxide solution and in 1.0 and 5.0% solutions of ascorbic and lactic acids for 10, 30 and 60 min. The controls were untreated seeds, seeds soaked in 0.2% solution of Kaptan zawiesinowy 50 WP for 30 min and seeds soaked in distilled water for 10, 30 and 60 min. Treating zinnia seeds with organic acids more significantly affected seed germination and health after deterioration than before, and improvement of germination capacity was usually correlated with decrease of the percentage of abnormal diseased seedlings. Deterioration had no influence on mean germination time, whereas in particular cases treating seeds with hydrogen peroxide and organic acids negatively affected this parameter. After deterioration regardless of treatment increased number of seeds free from fungi. Lactic acid followed by hydrogen peroxide and ascorbic acid effectively limited growth of A. alternata, A. zinnia and Fusarium spp. on zinnia seeds, however at higher concentration negatively affected seed germination and vigour. Moreover, treating seeds with hydrogen peroxide and organic acids many a time increased seeds infestation with B. cinerea.
