Abstract

A phenological study with the aim to elucidate flower and fruit development stages in species of Uncaria gambir was conducted in field trial of agricultural faculty of Andalas University-West Sumatra. Observation during flower and fruit organ development was done in eleven inflorescences. Quantitative and descriptive data were collected during one season of flowering time. Phenology of flower and fruit development could be classified in five stages, namely F0 (flower initiation), F1 (small bud scale), F2 (large bud scale), F3 (anthesis, flower opening) and F4 (fruit development). All these events had average completing time in 112 days, and could be detailed as follows: flower initiation stage (F0) took place in 20 days, small scale bud stage (F1) occurred in 27 days, and large scale bud and anthesis stage (F0 and F3) each took place in 5 days, meanwhile fruit development stage (F4=S0) would complete in 53 days. This result should be useful information especially for creating breeding programme in Uncaria gambir species.Key words: Uncaria gambir, phenology, flower development, fruit development.

Abstract. Nguyen TV, Kasim M, Anggraini T, Doan LN, Duong NV. 2025. Resilience of wild and cultivated bitter melon (Momordica charantia) under deficit irrigation in Vietnam. Biodiversitas 26: 5248-5257. Water scarcity increasingly constrains vegetable production in tropical regions, requiring adaptive strategies such as deficit irrigation and the use of resilient genetic resources. This study evaluated the physiological and agronomic responses of two Momordica charantia accessions—designated as the wild type (TCCS VP-BT08/16) and the cultivated type (TCCS VP-BT01/14)—under three irrigation regimes (80 %, 65 %, and 50 % of field capacity, FC) in a split-plot field experiment conducted during the 2024–2025 dry season in Vietnam. Growth traits, SPAD chlorophyll values, and cumulative dry fruit yield were assessed using ANOVA and Duncan's multiple range test (P < 0.05). Irrigation significantly influenced all measured traits (P ? 0.001). The cultivated type showed strong early vigor under full irrigation but declined rapidly after ~90 days under water stress, whereas the wild type maintained stable growth, branching, leaf production, and SPAD values across irrigation levels through 120 days. Dry fruit yield was sustained at 65% FC in both accessions (~185 g plant-¹ wild, ~178 g plant-1 cultivated) without significant reduction from full irrigation, while severe deficit (50% FC) caused moderate yield decline in the wild (~22%) and substantial losses in the cultivated type (~50%). These findings indicate that maintaining soil moisture at 65% FC can sustain bitter melon yield under dry-season conditions and highlight the superior drought resilience of the wild bitter melon as a valuable genetic resource for breeding climate-resilient cultivars.

Abstract. Nguyen TV, Kasim M, Anggraini T, Doan LN, Duong NV, Vo TCT, Do ST. 2026. Biochemical responses of a wild and a cultivated accession of Momordica charantia under contrasting soil moisture regimes. Biodiversitas 27 (4): d270403. https://doi.org/10.13057/biodiv/d270403. Water deficit is a major abiotic constraint affecting plant growth, functional traits, and genotype-level variation under field conditions. This study evaluated growth performance and antioxidant-related biochemical traits of a wild and a cultivated accession of bitter melon (Momordica charantia) under three soil moisture regimes (80%, 65%, and 50% field capacity) using a split-plot field design. Total Phenolic Content (TPC), Total Flavonoid Content (TFC), antioxidant activity (DPPH radical scavenging), and biomass-related traits were quantified in leaves at defined crop ages and in fruits at commercial maturity, and yield-based biochemical indices were calculated to integrate concentration and dry matter accumulation. Moderate moisture deficit (65% field capacity) was associated with increased TPC, TFC, and antioxidant activity in several instances, while severe deficit (50% field capacity) reduced biomass stability and biochemical performance, particularly in the cultivated accession. Fruits accumulated greater absolute biochemical yields per plant, whereas leaves exhibited stronger concentration-based responsiveness to moisture variation. The wild accession generally showed greater biochemical plasticity and higher yield-integrated metabolite production than the cultivated accession under moisture stress. These findings demonstrate a clear trade-off between metabolite concentration and biomass accumulation under drought conditions, with moderate stress generally supporting higher biochemical performance. The results highlight the importance of genotype selection and irrigation management in maximizing functional traits and support the use of wild germplasm in breeding strategies for improved drought adaptation in bitter melon.
