Effect of Periods and Media Storage on Viability of Cananga Seed (Cananga odorata (Lam.) Hook.f. & Thomson forma genuina)

Abstract

The suitable seed storage method is important to maintain seed viability. This study aimed to examine the effect of periods and media storage on the viability of cananga seed (Cananga odorata (Lam.) Hook.f. & Thomson forma genuina). The treatments used in the seed viability test were 0, 2, 4, and 6 weeks as period storage and cocopeat, ash, and charcoal as media storage. The seeds were stored in the plastic at room temperature (± 25°C). The variables observed in this study were seed moisture content, percentage of germination, maximum growth potential, average days of germination, T50, germination value, and the number of seeds that germinate during storage. The percentage of C. odorata seeds germination without storage is 54%. The seed storage for 2 – 6 weeks in ash and charcoal hush caused their viability was drop. The seeds storage of C. odorata up to 6 weeks in cocopeat could maintain seeds viability with a percentage of germination that has no significant difference compared to control. In general, cocopeat can be used as one of the storage media in the seed storage of C. odorata before sowing.Keywords: Cananga odorata, cocopeat, germination percentage, seed, viability
