Abstract

Watermelon (Citrullus lanatus (Thunb.)) is a horticultural crop with high economic value with a water content of up to 92% and is rich in vitamins A, E, and antioxidants. Watermelon is highly dependent on environmental conditions to grow well. Good environmental conditions certainly affect watermelon productivity. In order to develop watermelon cultivation efforts, it is necessary to conduct biological studies of watermelon, one of which is regarding the phenology of watermelon (Citrullus lanatus (Thunb.)) under different environmental conditions. This study was conducted from November 2025 to February 2026 in two locations, namely Bayang District, Pesisir Selatan Regency and Sangir District, Solok Selatan Regency with observation samples at each location of 20 replications. The parameters observed included flower emergence time, flowering duration, fruit emergence time, and fruiting duration at each location. Data were analyzed using a t-test with a significance level of 5%. The results of the study showed that there were differences in watermelon phenology from all aspects of observation, namely flower emergence time, flowering duration, fruit emergence time, and fruiting duration in the two research locations, where in Bayang District the average flower emergence time was 28.7 days after planting (DAP), flowering duration was 16.35 days, fruit emergence time was 45.05 DAP, fruiting duration was 39.5 days. In Sangir District the average flower emergence time was 19.2 DAP, flowering duration was 19.2 days, fruit emergence time was 35.3 days, and fruiting duration was 32.65 days.

Abstract

The mahkota dewa plant (Phaleria macrocarpa (Scheff.) Boerl.) plant is a medicinal plant with high economic and pharmacological value, so effective propagation techniques are needed to increase its production. One method used is grafting, the success of which is influenced by the planting medium. Based on this, a study was conducted on the effect of sawdust and cocopeat growing media on leaf growth in grafting crown of the gods plant. The study was conducted in January 2026 in the Lubuk Minturun area of ​​Padang City. This study used a Completely Randomized Design (CRD) with three treatments: soil (P0), sawdust (P1), and cocopeat (P2), each with six replications, resulting in 18 experimental units. Observed parameters included leaf number and leaf dry weight. Data were analyzed using analysis of variance (ANOVA). The results showed that the planting medium used had no significant effect on leaf number or dry weight.

Abstract

Samawuang (Pangium edule Reinw.) is a tree that has economic value and potential as a food source, but its existence is decreasing due to lack of cultivation and changes in environmental conditions. Environmental factors such as altitude, temperature, humidity, rainfall, and soil conditions are known to affect plant growth, especially in leaf organs that are sensitive to environmental changes. Based on this, a study was conducted to investigate the morphological response of samawuang leaves under different environmental conditions. The study was conducted from December 2025 to January 2026 in two locations, namely Dharmasraya (131 mdpl) and Solok (409–467 mdpl). The method used was descriptive research with a quantitative approach by taking 20 leaf samples at each location which were analyzed using a t-test at a significance level of 5%. Parameters observed included leaf length, leaf width, leaf stalk length, and number of leaf veins. The results showed that there were significant differences in leaf length and width between the two locations. The average leaf length in Dharmasraya was higher at 41.20 cm compared to Solok at 30.20 cm, while the average leaf width in Dharmasraya was 34.05 cm higher than Solok at 25.71 cm. Meanwhile, the length of the leaf stalk and the number of leaf veins did not show significant differences. This study shows that Pangium edule R. has significant variations in leaf morphology adaptation to different environmental conditions.

Abstract

Mangrove forests are important coastal ecosystems that function as shoreline protectors, carbon sinks, and habitats for many aquatic organisms. In Teluk Buo, Bungus, Padang City, mangrove stands have experienced pressure from land conversion and human activities, so information on natural regeneration is needed to support management efforts. This study aimed to determine the natural regeneration status of mangroves in Teluk Buo based on species density values. The study used a descriptive quantitative method with a plot sampling approach at three observation stations, each consisting of three plots selected by purposive sampling. Observation plots of 10 x 10 m were used for trees, 5 x 5 m for saplings, and 2 x 2 m for seedlings. Data were analyzed using species density and regeneration status criteria according to Shankar (2001). The results showed that two mangrove species were found, namely Rhizophora apiculata and Bruguiera gymnorrhiza. Station 1 had a seedling density of 75, sapling density of 12, and tree density of 26.33, indicating a sufficient regeneration status. Station 2 had a seedling density of 144, sapling density of 24, and tree density of 5.67, while Station 3 had a seedling density of 122, sapling density of 17.33, and tree density of 8.33; both stations indicated good regeneration status. Rhizophora apiculata was the dominant species at all growth levels, whereas Bruguiera gymnorrhiza showed limited regeneration. In general, natural regeneration of mangroves in Teluk Buo was classified as good to sufficient, with regeneration being more strongly supported by Rhizophora apiculata.
