Abstract
Sacha inchi (Plukenetia volubilis) is a plant originating from South America that can be processed into sacha inchi oil. Sacha inchi oil contains eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) which have positive impacts on human health. This study aimed to determine the effect of seed storage time on sacha inchi seed germination. The study was conducted in the experimental field of the Agrotechnology Study Program, UPN Veteran Yogyakarta from July 1 to August 31, 2024. The design used was a Completely Randomized Block Design with one factor and three replications. The factor was the accessions consisted of 3 accessions: Bogor, Cimahi and Lampung. The results of observations showed that seeds from Cimahi accessions had the highest germination percentage (16%) and germination speed (0.75 %/etmal), while seeds from Lampung accessions had the lowest germination percentage (0%) and germination speed (0%/etmal). The results of the tetrazolium test showed that seeds from Cimahi showed respiration activity in their embryos which was marked by the appearance of a red color, seeds from Bogor showed a red color on almost the entire surface, while seeds from Lampung showed the faintest red color among the others. Sacha inchi seeds are thought to have a dormancy phase of 2 months after being harvested.
