Abstract:
Background: Natural plant toxins can cause food poisoning upon intentional or unintentional consumption of wild plants. Some toxic wild plants can be mistaken for edible species because of their morphological resemblance. This study examined a poisoning case report of schoolchildren who consumed a steamed tuberous root of wild Ipomoea, misidentified as I. mauritiana, and experienced gastrointestinal toxicity. Objectives: This study aimed to identify the tuberous root of wild Ipomoea using the internal transcribed spacer (ITS) region as a DNA barcode and characterize compounds obtained using gas chromatography-mass spectrometry (GC-MS). Materials and methods: DNA was extracted from fresh and cooked samples of the storage root. PCR amplification and DNA sequencing of the entire ITS region were performed. FastTree and maximum likelihood analyses were used to obtain phylogenetic trees of the Ipomoea species. Root extracts were prepared for GC-MS analysis, and potentially harmful phytochemicals responsible for poisonous plant exposure were predicted based on a well-established plant toxin database. Results: ITS phylogeny showed a close relationship between wild toxic Ipomoea and edible I. mauritiana. The chemometric profile obtained from GC-MS analysis of the root extracts revealed the presence of 31 phytochemicals. Among them, two putatively toxic compounds identified were β-amyrin and coumarin. Conclusion: Misidentification of the wild poisonous plant reported herein resulted in toxic plant ingestion. Although most poisonous plant exposures are not life threatening, measures should be taken to ensure the safety of the general public.

Abstract:
Abstract Drinking water (DW) can serve as a route for disease transmission if not properly managed. The study assessed the effect of different factors on Escherichia coli quantities in DW in household water storage containers in suburban and rural villages in Laos and Thailand. Higher E. coli concentrations in DW were found in Laos compared to Thailand, especially in households without toilets (in Laos) and in rural rather than in suburban villages. In suburban Laos, house material, storage container types and lack of toilets were significantly associated with E. coli contamination of DW, whereas in rural Laos, corresponding significant factors were rain-fed water, containers with lids and lack of toilets. In suburban Thailand, rain-fed water, storage container types and container cleaning frequency were significantly associated with DW contamination, while house materials, manually collected rainwater and container cleaning frequency were associated with contamination in rural Thailand. Socio-demographic characteristics were less associated with E. coli contamination of DW in this study. Treatment of household stored water (e.g. boiling), regular cleaning of rain jars as well as the provision of household toilets, especially in Laos, can provide barriers against E. coli contamination of DW.

Abstract:
Seasonal flooded forest is one of the most important wetlands in northeastern Thailand, not only for its abundant biodiversity, but also as a source of carbon sequestration. Organic carbon plays an specially important role in the soil carbon cycle. To reinforce comprehension on soil organic carbon, five profiles in a northeast plateau were observed and determined. The most common trees were Albizzia Odoratissima, Combretum quadrangulare Kurz, and Streblusasper Lour. The contents of Soil Organic Carbon (SOC) varied from 3.52 g/kgto 5.90 g/kg in top soil and varied from 4.01 g/kg to 4.60 g/kg in sub soil. There was a close relationship between SOC content and basic soil properties, especially the bulk density of both top soil layer and sub soil layer. The distribution of SOC content was harmonized with distribution of plants. In comparative analysis, the flooded forest that composted with a high percentage of vegetation coverage (Khud Tew, Khud Chi Tao) had a significantly higher SOC content. The SOC storage varied from 2.65 kg/m2 to 4.18 kg/m2. Khud Chi Tao contained the maximum amount of SOC storage, whereas Kwo Chi Yai had the minimum. Limitation of flooded forest survival concerned over landscape change, particularly plant disappearance and waterlogged shortage. Therefore, vegetation and hydrology management have to be implemented practically to retain the existing organic carbon in wetlands and allow the soil to sequester additional carbon.

Abstract:
SummarySeeds can deteriorate rapidly under high heat and humidity, making it challenging and potentially costly to store orthodox seeds effectively in the tropics, thereby affecting agriculture development. This work explores the effectiveness of novel, low-cost technologies for storing seeds in warm, humid, resource-constrained environments, focusing on maintaining the viability of seeds already dry prior to storage. Seeds of okra (Abelmoschus esculentus (L.) Moench), sorghum (Sorghum bicolor (L.) Moench), and velvet bean (Mucuna pruriens (L.) DC) were kept for 12 months under roofed, outdoor screened porches. Seed moisture content prior to treatment was 6, 9, and 12% for okra, sorghum, and velvet bean, respectively. Treatments, replicated four times at each of two locations (USA [Florida] and Thailand), were technology suites involving vacuum drawn on glass jars with a modified bicycle pump, vacuum drawn on polyethylene bags with an electric vacuum sealing machine, desiccant (calcium oxide powder or zeolite Drying Beads® at a 2:1 ratio, by weight, of seeds to desiccant) in glass jars, and nontreated seeds in paper bags. Ambient temperature and humidity were variable and high, reaching over 35 °C and 83%, respectively, at both locations. Under these conditions, okra and sorghum germination percentages (across locations) without treatment declined from over 90% initially to 30 and 0%, respectively, by month 12. Both vacuum treatments and calcium oxide maintained high germination of okra (≈ 80%) and velvet bean seeds (nearly 100%) across locations. Glass, however, was superior to polyethylene in maintaining vacuum and stabilizing the moisture content of okra and sorghum seeds. Only zeolite reduced seed moisture below initial values, drying seeds to ultradry levels of <5%. With zeolite, sorghum germination stayed near 70% over time, while okra and velvet bean germination fell to <40 and <20%, respectively, by month 12, suggesting that, with the beads kept with dry seeds in storage rather than removing the beads after reaching a target level of seed moisture, the 2:1 ratio of seed-to-bead weight was too high for seeds that are sensitive to ultralow moisture. Findings have practical implications for inexpensive household- or community-level seed storage to deliver development impact.

Abstract:
Fragrance, which plays an important role in determining the economic value of rice to growers and consumers, is known to be controlled by the Badh2 gene. This study evaluated the grain quality characteristics and allelic variation of the Badh2 gene in 22 fragrant rice landraces from Thailand. The rice seed samples from farmers’ storage facilities in northern, northeastern and southern Thailand, plus two advanced breeding lines and three check varieties, were evaluated for seed morphology and grain quality, and their Badh2 genes covering intron 4 to intron 8 were re-sequenced. Almost all of the landraces were classified as large grain types, with medium to high gelatinization temperatures. The variation in the Badh2 gene by haplotype analysis correlated with grain aroma by sensory evaluation. The badh2-E7 was found in haplotype 1 with a strong aroma in KH, NDLP, and PLD, as in KDML105 and the moderately aromatic BNM-CMU, BNM4, and SKH, along with PTT1. Three haplotypes had different positions of SNP on the Badh2 gene with varying results in the sensory test. The present results suggest that some rice varieties could be potentially introduced as genetic resources for fragrant rice breeding programs or could be developed to highly palatable cultivars with geographical indications to increase the income of highland farmers.

Abstract:
Abstract. This study has developed optimal hedging policies for the multi-purpose Ubonratana Reservoir in northeastern Thailand based on its existing rule curves. The hedging policy was applied whenever the reservoir storage falls below a critical level for each month of the year. The decision variables, i.e. the set of monthly storages defining the critical rule curve that triggers rationing and the rationing ratio, were optimized by genetic algorithm (GA). Both single stage (i.e. with one critical rule curve and one rationing ratio) and two-stage (with two critical rule curves and ratios) of the hedging policy were considered in the optimization. To test the effect of the optimized hedging policies on reservoir performance, simulations were carried out, forced alternatively with the existing rule curves (i.e. without hedging) and the two optimized hedging policies. Performance was summarized in terms of reliability (time- and volume-based) and vulnerability. The results showed that the vulnerability was significantly reduced by using the optimized hedging rules. However, the number of water shortages increased with the optimized rules, causing the time-based reliability to worsen significantly. This should not be of concern since, although the number of shortages increased, the associated shortage quantities on most of these additional occasions were small, leaving the volumetric reliability largely unchanged.

Abstract:
Human activity negatively affects the sustainability of forest ecosystems globally. Disturbed forests may or may not recover by themselves in a certain period of time. However, it is still unclear as to what parameters can be used to reasonably predict the potential for self-recovery of human-disturbed forests. Here, we combined seed rain, soil seed bank, and seed emergence experiments to evaluate the potential for self-recovery of a highly disturbed, tropical, mixed deciduous forest in northeastern Thailand. Our results show a limited potential for self-recovery of this forest due to low seedling input and storage and an extremely high mortality rate during the drought period. There were 15 tree species of seedlings present during the regeneration period in comparison with a total number of 56 tree species in current standing vegetation. During the dry season, only four tree seedling species survived, and the highest mortality rate reached 83.87%. We also found that the correspondence between the combined number of species and composition of plant communities obtained from seed rain, soil seed bank, and seedling emergence experiments and the standing vegetation was poor. We clearly show the temporal dynamics of the seed rain and seedling communities, which are driven by different plant reproductive phenology and dispersal mechanisms, and drought coupled with mortality. We conclude that this highly disturbed forest needs a management plan and could not recover by itself in a short period of time. We recommend the use of external seed and seedling supplies and the maintenance of soil water content (i.e., shading) during periods of drought in order to help increase seedling abundances and species richness, and to reduce the mortality rate.

Abstract:
The purpose of the present study was to investigate the effect of paclobutrazol (PBZ) application time on growth, yield and starch content of cassava under rainfed conditions. A split-plots design was set up with four replications. The main-plot consists of two cassava cultivars (CMR and RY-7) and three PBZ application times (90, 135 DAP and two combined 90 and 135 DAP) in comparison with no paclobutrazol application (control) assigned as sub-plots. The study showed that all PBZ application times reduced plant height. PBZ single application at 135 DAP or two combined application at 90 and 135 DAP increased leaf number per plant and leaf area index. The maximum storage root yield was obtained when PBZ applied at 135 DAP over without PBZ application (control) by 46% in the present study. PBZ application at 90 DAP combined with 135 DAP produced the highest starch content of the storage roots. In the present experiment, two cassava cultivars did not show a significant difference on growth, yield and starch content in storage root.
