Abstract

Rosela (Hibiscus sabdariffa L.) is a medicinal plant. Rosela has a chemical compound that can provide many benefits. Efficacy of rosella to prevent disease, treat disorders of various diseases with gossiptin anthocyanin content and gluciside hibiscin contained in it. This research was conducted at the Laboratory of College of Agricultural Sciences of Labuhan Batu University Foundation, North Sumatera Province. This research was started in March 2017. This research used Non-Factorial Randomized Block Design (RAK) with the harvesting period (P) P0: Control, P1: 1, Clock P2: 2 Hours, P3: 3 Hours P4: 4 Hours P5: 5 Hours P6: 6 Hours P: 7 Hours. The highest rate of germination was found in P7 treatment of 3.22 days. The highest normal germination percentage was found in P5 and P7 treatment of 66.67%. Than highest abnormal germination percentege was found in P3, P4 and P6 treatment of 33.33 %. Keywords : Rosela, Old Immersion

Abstract

The propagation plants coffee is carried out in generative manner and needs be optimized with treating gibberellin hormone and water temperature in germination stage of coffee seeds. This research aimed to know the effects of changes in the physical condition of coffee seeds with concentration of gibberellin hormone (GA3) and different water temperatures. This research conducted at the Seed Technology Laboratory Faculty Agiculture, Andalas University from July to September 2020. The method used was Randomized Complete Design with 3 replications. The parameters observed were seed weight early (g), seed weight after treatment (g), seed moisture content early (%), moisture content seed after treatment (%) and membrane leakage (μmhos). Results showed that 200 ppm of gibberellin hormone concentration can increase weight of seed after treatment with 4.28 g. The best seed moisture content was at 90°C water immersion temperature with 48.28%.
