Abstract

This research was conducted with the aim of obtaining the optimal dose of humic acid (HA) and liquid organic fertilizer (LOF) from seaweed extract that can enhance the growth and total flavonoid content of Brassica juncea L. The method used in this study was experimental with a randomized complete block design with two factors. The first factor was HA, consisting of 4 dose levels: 0, 4, 8, and 12 g/kg, while the second factor was LOF from seaweed extract, consisting of 4 dose levels: 0, 1, 2, and 3 mL/L. Each treatment was replicated four times. Parameters were observed on the 42nd day, including plant height, leaf number, leaf area, dry weight, and total flavonoids. Data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan's Multiple Range Test with a confidence level of 95%. The results showed that the dose of 4 g/kg HA and 2 mL/L LOF was the best dose for enhancing growth and total flavonoid content, producing an average plant height of 19.25 cm, a leaf number of 5.75, a total leaf area of 179.8 cm2, a dry weight of 0.57 grams, and a total flavonoid content of 0.106 mg QE/g sample.

Abstract

Bidens pilosa is a plant known for its secondary metabolites with therapeutic properties. This study aimed to examine the effects of different light intensities on the morphology, anatomy, chlorophyll content, and secondary metabolite production of B. pilosa in the Arboretum of Universitas Padjadjaran. The shaded and unshaded area had light intensities of 5828 and 32768 lux, respectively. Leaf samples were collected from three different individuals in each area, with three leaves taken per plant. Morphological and anatomical traits such as leaf thickness, leaf area, stomatal density, and chlorophyll content were observed, along with secondary metabolite content. Results showed that plants in the shaded area had thinner leaves (0,19 mm) and lower stomatal density (275,16 cells/mm2) but a larger leaf area (4 cm2) and higher chlorophyll content (29,33 CCI) compared to leaves in the unshaded area, which had thicker leaves (0,213 mm), higher stomatal density (310,83 cells/mm2), a smaller leaf area (2,33 cm2), and lower chlorophyll content (27,27 CCI). Alkaloids, flavonoids, tannins, and saponins were detected in both conditions, with a higher level of alkaloid and tannin in unshaded plants. These findings enhance our understanding of the relationship between light intensity influences plant morphology, photosynthesis, and secondary metabolite production, with potential applications in cultivation and medicinal use.
