%X Santoso BB, Budianto A, Aryana IGPM. 2012. Seed viability of Jatropha curcas in different fruit maturity stages after storage. Nusantara Bioscience 4: 113-117. The effect of fruit maturity stages and seed storage period to seed viability were investigated. Seed samples of West Lombok, West Nusa Tenggara genotype of Jatropha curcas were collected from standing two year old trees at experimental field. The seed samples obtained were in four different stages of fruit maturity involving early maturity (green fruit), physiological maturity (yellow fruit), over maturity (brownies fruit), and senescence (black-dry fruit). The results showed that fruit maturity had an influence as well storage period on the seed viability of Jatropha curcas. The best fruit maturity stage for seed viability including seed oil content was yellow fruit and brownies fruit. For germination to be maintained or preserved, seeds could be stored in the ambient room storage for at least five months. For the purpose of oil extraction, seed should preferably be stored maximum not more than four months under ambient room conditions.
