Abstract
Jernang rattan is a resin known as “dragon’s blood” and belongs to e family arecaceae. Its uses vary, including being a source of supply for the ceramics, jewelry, glass, textile, and pharmaceutical industries. This study is to determine the germination response of rattan jernang seeds (Daemonorops didymophylla Becc.) in various treatments of dormancy of rattan jernang seeds. The research was conducted in Silangit, Siborongborong District, North Tapanuli Regency, starting from April 2023 to July 2023. The study used a non-factorial Randomized Block Design (RBD). The treatment factors are: P0 (seeds without treatment / control), P1 (soaking seeds with ordinary water 24 hours), P2 (scarification of seeds / sanding), P3 (soaking seeds with KNO3 0.5% 24 hours) and P4 (soaking seeds with coconut water 24 hours). The parameters observed are growth potential, germination test includes the percentage of normal sprouts and the percentage of dead sprouts. The conclusions were obtained soaking treatment of rattan jernang seeds in 0.5% KNO3 solution for 24 hours had a very real effect on on the percentage of germination, the percentage of normal sprouts and the percentage of dead sprouts.
