Improve Seed Germination

Background Melatonin (MEL) is a signaling molecule in plants that affects developmental processes during vegetative and reproductive growth. Investigations have proved that exogenously applied MEL also has the potential to improve seed germination and plant development. Methods In the present study, seeds of stevia, a species with a very low germination rate, were germinated on an agar gel (AG) containing MEL at various concentrations (5, 20, 100, and 500 µM) in light. Seeds germinated on AG without MEL were used as controls. For the first 24 or 48 h of germination, the seeds were maintained in darkness as a pre-incubation step. Some seeds were not exposed to this pre-incubation step. Results At concentrations of 20 and 5 µM, MEL significantly improved germination, but only in seeds pre-incubated in darkness for 24 h (p < 0.001). At concentrations of 100 and 500 µM, MEL had an inhibitory effect on germination, regardless of the pre-incubation time. Melatonin also affected plantlet properties. At a concentration of 20 µM, MEL increased plantlet fresh weight and leaf numbers. At a concentration of 5 µM, it promoted plantlet height. Regarding root development, the most favorable MEL concentration was 500 µM. Biochemical analysis revealed that MEL promoted higher pigment concentrations but hampered superoxide dismutase activity. On the other hand, the concentrations of sugars and phenolics, as well as the activities of catalase and peroxidase, increased at a MEL concentration of 500 µM. Discussion The results suggest that MEL can improve germination of positively photoblastic stevia seeds and that it can play a role in plantlet development. However, the effects observed in the present study depended on the quantity of MEL that was applied.

Hypercholesterolemia is a state of increased levels of LDL (Low Density Lipoprotein) and total cholesterol in the plasma. Stevia leaves have benefits to overcome hypercholesterolemia. The aimed of this study was to obtain ethanol extracts of Stevia rebaudiana Bertoni leaves which have activity to reduce total cholesterol levels in patients with hypercholesterolemia with effective doses. The method that will be carried out to achieve this goal was to make extracts by maceration of Stevia rebaudiana Bertoni leaf powder using a water solvent for 5 days. Testing antihypercholesterolemia activity by giving treatment to 20 male white rats. Rats were divided into 5 treatment groups. Group I was negative control, II was simvastatin control, III extract was 30 mg / 200 g BW, IV extract was 60 mg / 200 g BW, V extract was 120 mg / 200 g BW. The mice were induced by propylthiouracil 12.5 mg / day and high-fat feed for 21 days, after which the rats were given the test for 14 days. Cholesterol levels were measured on days 0, 21st and 28th. The method of determining cholesterol levels uses the Easy Touch tool. On the 35th day, a total cholesterol level was examined and data analysis was performed. The results showed that the ethanol extract of stevia leaves had antihypercholesterolemia activity, extract dose of 30 mg / 200 g BW had antihypercholesterolemia activity which was equivalent to simvastatin.
