Abstract

Ferns are a potential source of biostimulant compounds due to their rich content of bioactive secondary metabolites. This study aimed to evaluate different solvents for extracting bioactive compounds from Davallia denticulata and to identify the optimal extract formulation for enhancing the growth and yield of Kopay chili. This research was conducted from February to May 2024 at the Plant Physiology Research Laboratory and Greenhouse, Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Andalas, Padang. A completely randomized design with 16 treatment combinations involving four solvents (A1 = aquadest, A2 = methanol, A3 = ethanol, A4 = butanol) and four extract concentrations (B0 = 0 mg L-1, B1 = 25 mg L-1, B2 = 50 mg L-1, and B3 = 100 mg L-1) was employed. Plant growth parameters responded differently to various combinations of extract concentration and solvent type. Methanol extract at 100 mg L-1 significantly increased plant height, ethanol at 50 mg L-1 improved shoot dry weight and root biomass, butanol at 100 mg L-1 increased chlorophyll b and total chlorophyll, and methanol at 25 mg L-1 resulted in higher fruit weight. These results indicate that Davallia denticulata extract, when properly formulated, holds strong potential as a natural biostimulant to improve growth and productivity in chili cultivation.

Abstract

Maize (Zea mays L.) is one of the major cereal commodities with a strategic role in various sectors of societal needs. The application of plant-derived biostimulants has emerged as an alternative approach for enhancing plant physiological performance, including the use of leaf extract from Cnidoscolus aconitifolius (chaya). This study aimed to evaluate the effects of different solvent types and extract concentrations of C. aconitifolius leaves on the chlorophyll content of maize plants. A two-factor Completely Randomized Design (CRD) was used, consisting of: (a) solvent types (aqueous, ethanol, methanol, and butanol) and (b) extract concentrations (control, 25 mg/L, 50 mg/L, and 100 mg/L). The results indicated that neither solvent type nor extract concentration had a significant effect on any chlorophyll parameter. However, the aqueous-based extract at 25 mg/L tended to produce the highest chlorophyll a and total chlorophyll content, while the highest chlorophyll b content was observed in the 25 mg/L butanol extract treatment. In contrast, the 100 mg/L ethanol extract treatment showed a tendency toward the lowest chlorophyll content. These findings suggest that the effectiveness of C. aconitifolius extract as a photosynthetic biostimulant in Z. mays remains limited and is likely influenced by the solubility of its bioactive compounds in the solvents used.
