Studies on Storage and Viability of Jamun Seeds (Syzygium cuminii Skeels)

摘要

An experiment was conducted during 2015-2016 to study the storage and viability of jamun seeds (Syzygium cuminii Skeels). Studies revealed that the seeds possessed short viability due to recalcitrant. This could be overcome by finding a suitable storage temperature and container for storage of jamun seeds. This study showed significant differences among the various storage and treatments. The seeds stored at refrigerated (5p C) gave higher germination per cent at zero, 15, 30, 45, 60, 75 and 90 daysafter extraction (DAE)(78.56%, 73.52%, 43.33%, 60.41%, 60.09%, 53.76% and 54.36% respectively) compared to seed of other storage conditions. Seeds treated with Poly bag + Trichoderma harzianum (86.68%, 66.29%, 22.64%, 35.13%, 33.21%, 28.78% and 30.75% respectivelyjat zero, 15, 30, 45, 60, 75 and 90 days after extraction (DAE) gave higher germination followed by seeds kept in poly bag and seeds treated with Poly bag + Charcoal powder. Seeds stored at room temperature are not recommended for jamun seed storage because seed deterioration rate under such condition is higher within 15 days of extraction. The use of bio-control agents and moisture holding media are therefore recommended as an approach for extending the viability and potential to increase thegermination of jamun seeds.
