Abstract

Chrysanthemum morifolium contains flavonoids which have antioxidant properties and was useful in treating various diseases. The production of flavonoids from plants can be done in vitro through callus culture. Auxin 2,4-D growth regulators and organic compounds such as coconut water added to the media can affect the success of callus formation and secondary metabolite synthesis. The purpose of this study was to obtain the best treatment of 2,4-D concentration and coconut water that can increase the growth and total flavonoid levels of C. morifolium callus cultures. The method used in this research was the experimental method completely randomized design (CRD) with 8 treatments, namely 1 ppm 2,4-D + 10% coconut water (CW); 2 ppm 2,4-D + 10% CW; 3 ppm 2,4-D + 10% CW ; 4 ppm 2,4-D + 10% CW; 1 ppm 2,4-D; 2 ppm 2,4-D; 3 ppm 2,4-D; 4 ppm 2,4-D in 4 replication. The results showed that the treatment of 4 ppm 2,4-D and 10% CW was the best treatment combination, resulting in an average callus size (1.4 cm), fresh weight (0.19 grams), dry weight (0.16 gram) and total flavonoid content (1.873 mgQE/g)

Abstract

Salt affects plant growth due to increased soil osmotic pressure and plant nutrients disturbance. Most plants are susceptible to high salinity which can cause physiological and biochemical interference. This research was conducted to obtain a possible salinity level for mustard greens (Brassica juncea L.) to grow well and the best humic acid dosage to reduce salinity damages and to gain high total flavonoid content. This research used Randomized Block Design method with two factors and four replications. The factors are salinity levels (control, 50, 75, and 100 mM) and humic acid dosage (control, 2, 4, and 8 g/kg). In the parameters which had interactions between the two treatments, the highest results were obtained with a combination of 100 mM salinity and 12 g humic acid, such as plant height (33.35 cm), leaf area (379.66 cm2), fresh weight (22.41 g) and dry weight (1.54 g). The highest results on leaf number (8.5 leaves) and total flavonoid content (0.074 mgQE/g sample) were obtained with 100 mM salinity. Humic acid dose of 12 g gave the highest result on leaf number (8.69 leaves) and total flavonoid content (0.095 mgQE/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.
