Dyah Priandini, Muhamad Rahmad Suhartanto, Abdul Qadir


Development of papaya fruit production is influenced by the availability of seed quality. High seed quality is maintained during seed storage. Estimation of vigor in relation to storability can be detected by accelerated aging test. This research aims to develop physicall accelerated aging test by, 1)determine the impact of physical accelerated aging on vigor and viability parameters on papaya seed variety Callina and Sukma, 2) determine the levels of seed moisture content and effective period of physicall accelerated aging to predict vigor of papaya seed. This research was conducted at the Laboratory of Seed Science and Technology and Green House Leuwikopo, Department of Agronomy and Horticulture, IPB in January-May 2016 using a randomized complete block design with three replications. Seeds aged by the aging equipment MPC IPB 77-1 MMM. The results showed that the aging time decreased germination value in papaya seed variety Callina and Sukma with equation y=-0.1389x3+3.3333x2–25.25x+81.5 and y=0.0171x3+0.2028x2-9.9956x+81.095. Effective imbibition is 96 hour with moisture content 63-70% in both varieties. The effective of aging time treatment at 0x4, 1x4, 2x4, 3x4, dan 4x4 minutes.

Keywords:imbibition, moisture content, viability, vigor
