Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole

Abstract

The potato processing industry in Indonesia continues to face high market demand, while domestic production remains insufficient (reaching only 1.22 million tons in 2023), resulting in dependence on imported raw materials. The expansion of industrial potato cultivation in medium-altitude regions offers considerable potential due to land availability; however, it is constrained by high-temperature stress, requiring varieties that are both tolerant and high yielding. This study aimed to evaluate the growth response and yield performance of three industrial potato varieties Ventury Agrihorti (local), Atlantik (introduced), and Bliss/Chitra (introduced) under two contrasting altitude conditions: medium altitude (600 masl) and high altitude (1500 masl). The experiment employed a Split Plot Design, with observations covering growth parameters, yield components, and tuber quality indicators, including tuber specific gravity (SG). The results revealed a significant interaction between altitude and variety on several parameters, such as plant height, specific leaf weight, number of tubers, and tuber weight per plant. At medium altitude (600 masl), the Atlantik variety demonstrated the best performance, achieving a productivity of 40.39 t/ha with the highest tuber weight. However, Atlantik produced a high proportion of oversize tubers (41.97%), which does not meet industry grading standards. Conversely, at high altitude (1500 masl), Bliss/Chitra showed superior yield performance with a productivity of 42.96 t/ha, followed by Ventury at 38.46 t/ha. Ventury and Bliss/Chitra also excelled in tuber size distribution, producing the majority of tubers (approximately 94–95%) within the Normal category (Ø 4.5–9 cm), which aligns with industrial processing requirements in both altitude conditions. The specific gravity (SG) values of all three varieties ranged from 1.08 to 1.09, indicating compliance with the minimum quality threshold for potato processing industries (>1.08).

Abstract

Sunflowers have excellent prospects for future development in Indonesia. This commodity offers a variety of uses, from food and medicine to industrial use and even as a beauty product. Currently, development is focused on marginal land, particularly sandy soil. However, such land is known to have various limitations, necessitating innovations to enable its use as cultivation. One such approach is the application of fertilization technology using maggot compost and chicken manure. The purpose of this study was to evaluate the effectiveness of maggot compost and chicken manure on sunflowers in sandy soil. This study was conducted in Pasir Putih, Padang City, from June to September 2025. The design used in this study was a randomized block design with two factors and three replications. The first factor was the dose of maggot compost and the second was the dose of chicken manure. The results showed that the application of chicken manure and maggot compost at various doses resulted in increased growth and yield of sunflowers in sandy soil with each dose increase. Maggot compost at a dose of 20 g/plant and chicken manure at a dose of 30 g/plant had an interaction on plant height. Meanwhile, at a dose of 20 g/plant of chicken manure fertilizer and 15 g/plant of maggot compost, there was an interaction on the number of sunflower seeds.

Abstract

Weeds are a significant constraint to crop production as they compete for vital resources and release allelochemicals that may hinder the growth of surrounding plants. This study investigated the allelopathic effects of plant litter from Kyllinga brevifolia, Eleusine indica, and Sphagneticola trilobata on the germination and early development of Lactuca sativa. Two bioassays were conducted: a sandwich method in the laboratory and a pot experiment in a greenhouse. Dried weed residues were applied at concentrations of 1%, 2%, 3%, and 4% to evaluate their impact on seed germination, root and shoot elongation, and biomass accumulation in lettuce. The results showed that all three species inhibited seed germination and seedling growth in a concentration-dependent manner. In the sandwich assay, germination rates at 4% residue concentration declined to 58.89% (K. brevifolia), 76.67% (E. indica), and 46.67% (S. trilobata), compared to 96.67% in the control. The strongest inhibition of radicle growth was observed in K. brevifolia (91.60%). In the pot experiment, both K. brevifolia and S. trilobata consistently reduced all measured growth parameters. At 4%, shoot length declined to 9.18 mm and 5.42 mm, and dry shoot weight decreased to 2.90 mg and 3.09 mg, respectively. In contrast, E. indica slightly increased shoot biomass at moderate concentrations, suggesting a potential stimulatory effect. These findings demonstrate that residues from these weeds possess strong allelopathic potential and could be explored as natural agents for environmentally friendly weed management.

Abstract

Cuscuta australis (commonly known as Tali Putri) is a parasitic weed that extracts water, minerals, and nutrients from its host plants to sustain its life cycle. Among its shared hosts, Asystasia gangetica (Israel grass) is highly susceptible due to its soft stem structure, which facilitates haustorial penetration and efficient nutrient transfer. Although generally regarded as a harmful weed, C. australis has demonstrated pharmacological potential owing to its secondary metabolites and antioxidant properties, both of which are relevant in disease treatment. This study investigated the effect of altitude on the phytochemical profile, antioxidant activity, moisture content, and ash content of C. australis and its host plant. A survey method was applied across three altitudinal zones (lowland, midland, and highland) with seven replications per site. Laboratory analyses were performed at the Plant Physiology Laboratory, Faculty of Agriculture, Andalas University, and the Higher Education Service Institution (LLDIKTI) Laboratory. Data were analyzed using analysis of variance (ANOVA) with the F-test, and significant differences (p < 0.05) were further evaluated using Duncan's New Multiple Range Test (DNMRT). The results showed that C. australis grown at high altitude exhibited the highest antioxidant activity (173.35 µg/ml), moisture content (9.06%), and ash content (5.16%). Similarly, A. gangetica collected from highland sites demonstrated superior antioxidant activity (64.39 µg/ml), moisture content (8.82%), and ash content (7.07%). By contrast, altitude had no detectable effect on the phytochemical composition of either species, both of which consistently contained flavonoids, alkaloids, phenolics, terpenoids, and triterpenoids. These findings indicate that highland populations of C. australis and A. gangetica possess enhanced bioactive properties, suggesting that high-altitude habitats may provide the most suitable raw material sources for pharmaceutical applications.

Abstract

The titan arum (Amorphophallus titanum (Becc.)), an endangered and endemic flora from the island of Sumatra, faces a significant risk of extinction. Conservation efforts for the titan arum were undertaken, including in vitro conservation through tissue culture. The study aimed to determine the optimal concentration of the growth regulator Benzyl Amino Purine (BAP) for inducing shoot formation in titan arum and to observe cellular changes during the shoot stage through histological test. This research was conducted from November 2023 to March 2024 at the Tissue Culture Laboratory, Andalas University. The experiment was arranged in a Completely Randomized Design (CRD) with five treatment levels: 2, 3, 4, 5, and 6 ppm.  Data analysis was performed using an F-test at a 5% significance level. If the F-test showed significant differences, further testing was carried out using Duncan's Multiple Range Test (DMRT) at a 5% significance level. Meanwhile, data on explant rooting percentage and root count were presented as means and standard deviations. Results indicated that various concentrations of BAP could induce shoots formation of Amorphophallus titanum Becc., with the percentage of explants forming shoots reaching 80–95%.  The concentration of 5.0 ppm BAP was the most effective, yielding the highest average number of shoots at 7.80. Histological test revealed cell enlargement at the shoot tips. This research is pivotal for the conservation of titan arum and promotes further studies in in vitro culture techniques.
