Abstract

This study evaluated the predatory potential and functional responses of the different stages of the yellow netted lady beetle (YNLB), Heteroneda billardieri, against all nymphal instars of the mango leafhopper (MLH) in the laboratory. The 3rd instar larva and the female and male adults of YNLB were offered varying densities of MLH in vials, and the number of consumed MLH was recorded after 24 hours. The prey-consumption data were analyzed using logistic regression to estimate the age-specific functional response to MLH. Results showed that the 3rd instar H. billardieri has the highest predatory capability relative to the adult predators. At the highest prey density, 3rd instar larvae consumed 14.67 and 15.33 of the 2nd and 3rd instar MLH, respectively. It also has the highest attack rate and shortest handling time, with values of 0.089 and 0.71, respectively. All tested stages of H. billardieri exhibit a Type II functional response, characterized by a curvilinear increase in predation rates with increasing prey density. The results imply that the field releases using the 3rd instar H. billardieri can achieve the highest biological control efficiency. However, field studies should be conducted to verify these results.

Abstract

The ability of cycads to grow in harsh environments is thought to be associated with endophytic bacteria in their roots. This study aimed to characterize endophytic bacteria from Cycas rumphii and Dioon spinulosum as stress-tolerant plant growth-promoting bacteria (PGPB). Fine roots of C. rumphii and D. spinulosum were isolated using serial dilution plating and characterized through colony morphological observation, hypersensitivity, antagonistic activity, PGP activity, and abiotic stress tolerance assays. Fourteen isolates were obtained (eight from C. rumphii and six from D. spinulosum), with higher abundance and diversity in D. spinulosum (2.51 × 10¹⁰ CFU/g; H′ = 2.016) than C. rumphii (4.64 × 10⁹ CFU/g; H′ = 1.752). All isolates were non-pathogenic; 92% fixed nitrogen, 92% solubilized phosphate, and one (DS1A) produced IAA (0.200 ppm). Four isolates showed antagonism against Xanthomonas campestris (0.40–0.67 cm inhibition) and tolerance to drought, salinity (5–10%), and moderate heat, with growth at pH 5–6. Molecular identification by 16S rRNA sequencing revealed that CR1A, CR1B, and DS1B belong to Stenotrophomonas maltophilia, whereas DS1A belongs to Bacillus sp. These findings highlight cycads as a source of endophytic PGPB candidates for supporting plant health, particularly when grown in the environmental stress condition areas.

Abstract

Soil salinization is a significant constraint to global food security, with rice (Oryza sativa L.) being particularly prone to salinity stress. As a sustainable mitigation approach, plant growth-promoting rhizobacteria (PGPRs) are potential candidates for improving crop tolerance. This study investigates the performance of PGPR strain Enterobacter cloacae UIA3, noted for producing indole-3-acetic acid and nutrient solubilization, in establishing a symbiotic relationship with rice under salinity conditions. Three rice varieties, Pokkali, MR297, and IR64, under four salinity levels (0, 50, 100, and 150 mM NaCl) were analyzed for physiological response and symbiotic compatibility. A host-specific interaction was observed where the salt-tolerant Pokkali variety showed a strong positive association through enhanced root hair development and significant improvement in the growth of inoculated plants under stress. However, the salt-sensitive varieties of MR297 and IR64 showed severe root damage and exhibited minimal bacterial colonization. This indicates that the performance of E. cloacae UIA3 is effective mainly as bio-inoculation in salt-tolerant rice genotypes. Thus, host specificity is indispensable in the microbial strategy for saline agriculture. Overall, the results highlight avenues for PGPR strain E. cloacae UIA3 as an environmentally friendly bioinoculant under saline environments.

Abstract

Conserving, cultivating, and categorizing the traditional vegetable varieties is crucial for future food security, as they serve as reservoir of biodiversity. Among that, sweet pepper is an important food crop as it is rich in nutrients. Its demand in India is continuously increasing, highlighting the need to characterize and to evaluate its morphological diversity to improve varietal development programs. Characterizing sweet pepper germplasm can improve breeding programs by selecting parents based on morphological attributes. Forty two genotypes of sweet pepper collected and multiplied from PAU, Ludhiana exhibited the distinct variation for majority of the examined phenotypic traits. Flower morphology with white corolla, pale blue anther along with semi-drooping orientation leads to good fruit set. Square-shaped fruits were predominant and had high consumer preference. Principal component analysis revealed that PC1, PC3, PC8, PC9, PC10, PC14, and PC15 were dominating with fruit attributes Whereas, PC2, PC4, PC6, PC7, PC11, PC12, PC13, and PC16 were pronounced for plant traits and PC5 exhibited dominance for floral attributes. Further cluster analysis revealed that genetic diversity prevailed among the genotypes for morphological attributes aiming the selection of elite parents that can be successfully utilized in the breeding programs as well as conservation of the genotypes for the future.

Abstract

Unlike other crops, soybeans can be produced for both direct human consumption and industrial use. However, soybean production is highly sensitive to drought. This is because drought conditions can reduce photosynthesis and crop yield. This study aimed to investigate drought adaptations in soybean plants, including stomatal control, drought-induced carbon assimilation, and avoidance. The study was conducted in a greenhouse under controlled conditions using a split-plot design with 3 stress levels (100%, 50%, and 30% of field capacity), 4 varieties (Dering-1, Dering-2, Detap-1, and Argomulyo), and 2 stress periods (vegetative and generative). Strong variation in yield was observed across all drought-affected plant growth factors, including photosynthetic rate and grain yield. Under moderate stress conditions (achieving a 0.8 t/ha yield), the Detap-1 variety fully maintained photosynthetic capacity and appropriately modulated stomatal closure and stomatal regulation to achieve the most efficient water control. This leads to the conclusion that Detap-1 is best suited to the dryland conditions of the varieties studied due to its strong physiological adaptability.

Abstract

The development of superior cultivars and the availability of high-quality seedlings require stable in vitro propagation. This study evaluated the effectiveness of different culture media for the in vitro propagation of local West Sumatra cayenne peppers using a Completely Randomized Design with eight treatments and six replications. Further testing used the Duncan Multiple Range Test. This research was conducted in the tissue culture laboratory of Mahaputra Muhammad Yamin University, Solok, West Sumatra. Callus initiation and shoot regeneration were conducted on MS medium with various auxin–cytokinin combinations, while root induction was tested on MS and WPM supplemented with auxins. Explants consisted of the first leaf and epicotyl from 21-day-old chili seedlings. The highest callus induction (100%) was observed on MS medium supplemented with 3 mg/l BAP + 0.5 mg/l IAA and MS medium supplemented with 4 mg/l 2,4-D for both types of explants. The highest embryogenic callus formation (98.45%) was obtained on MS + 3 mg/l BAP + 0.5 mg/l IAA. Optimal shoot regeneration (5.29 shoots) was achieved on MS + 2 mg/l BAP + 1 mg/l NAA, whereas the best root induction occurred on WPM + 1 mg/l NAA.

Abstract

The current land suitability criteria for konjac are incomplete and fail to consider land dimensions and quality, which influence optimal yield. This research aims to develop criteria for konjac land suitability based on the dimensions, quality, and characteristics of selected land. In Gorontalo Province, Indonesia, 131 land units were surveyed to obtain data on the quality and characteristics. Selection of land dimensions, quality, and characteristics using Structural Equation Modeling (SEM) with Partial Least Squares (PLS). Meanwhile, the optimum yield and distinguished land suitability criteria for konjac plants using the boundary line method. The results indicated that intrinsic and extrinsic dimensions determined the new land suitability criteria. In the intrinsic dimension, land quality was assessed based on root conditions, oxygen availability, nutrient availability, nutrient retention, and sodicity. For the extrinsic dimension, land quality only comprised temperature, water availability, land preparation, and erosion hazard. Land characteristics in the intrinsic dimension consisted of soil drainage, texture, bulk density, particle density, porosity, pH, organic C, CEC, base saturation, total N, available P, and exchangeable K. For the extrinsic dimension, land characteristics included slope, soil erosion, surface rocks, and rock outcrops. The highest optimum yield of konjac was 9.17 t/ha, and the lowest was 6.69 t/ha, respectively.

Abstract

Climate change is related to changes of climate patterns that impact unpredictable weather phenomena. These phenomena can include extreme heat, extremely low temperatures, drought, or extremely high rainfall. With high adaptability, sugar palm (Arenga pinnata Merr.) can be one of the conservative plants that have a vital role in mitigating global climate change. Sugar palms have a high ability of carbon dioxide (CO2) sequestration and store it in the form of biomass. The results of the review show that palm trees have an inherent tolerance mechanism, for example under dry conditions, sugar palm produces lignin to strengthen cell walls and increase antioxidant in the form of osmoprotectants. However, the lack of empirical data and detailed studies hinders a deeper understanding of the limits of this tolerance. This article highlights significant research gaps and recommends future studies to investigate in more detail gene-environment interactions, genetic adaptation potential, and the role of specific metabolites in sugar palm. Overall, sugar palm has a fairly high carbon absorption capacity of > 85 t/ha/year. Therefore, this article is expected to not only fill the knowledge gap but also serve as a foundation for conservation efforts and the sustainable use of sugar palm in facing global climate.
