In the present study, the differences between the chemical compositions of the essential oils obtained from the leaves and flowers of two cultivars of M. cajuputi collected from Moc Hoa district, Long An province. By using Gas Chromatography-Mass Spectrometry, a total of 105 components have been identified in the essential oils of four samples of two M. cajuputi cultivars such as “Tràm gió” leaves, “Tràm gió” flowers, “Tràm cừ” leaves and “Tràm cừ” flowers. The Agglomerative Hierarchical Cluster (AHC) and Principal Component Analysis (PCA) were performed to show the similarities/dissimilarities in chemical compositions among the four studied samples. As a result, the components of the essential oils of four studied samples were divided into two clusters. Cluster I included two samples such as “Tràm gió” leaf and “Tràm gió” flower with high presence of 1,8-cineole (35.12 and 17.69%), linalool (3.31 and 5.03%), (R)-α-terpinyl acetate (9.17 and 8.1%). Cluster II comprised “Tràm cừ” leaf and “Tràm cừ” flower with the high concentration of α-pinene (9.87 and 12.19%), γ-terpinene (10.48 and 11.3%), p-mentha-2,4(8)-diene (8.8 and 12.7%).

Rooftop vegetable productions are becoming an important part of the recent rejuvenation of urban agriculture particularly in densely populated urban areas. However, due to weight limits often associated with rooftop growing systems, rooftop plant growing media including soil, may not contain optimal fertility levels required to maximize plant growth and productivity. Therefore, the success of rooftop vegetable production often depends on proper fertility management schemes to create optimal plant growing conditions. Therefore, an experiment was conducted to investigate combine impacts of composted poultry manure (CPM) and inorganic fertilizers on growth and yield of tomato under rooftop growing conditions. The experiment was arranged in a completely randomized design (CRD) with eight treatments and three replications. The treatments included T1: Control (no CPM and no NPK), T2: 4 ton CPM ha-1, T3: N55P15K50 kg ha-1, T4: N110P30K100 kg ha-1, T5: N165P45K150 kg ha-1, T6: 4 ton CPM ha-1+ N55P15K50 kg ha-1, T7: 4 ton CPM ha-1+ N110P30K100 kg ha-1, and T8: 4 ton CPM ha-1+N165P45K150 kg ha-1. The results showed that NPK fertilizers alone and CPM combined with NPK fertilizers greatly improved tomato plant growth and fruit yield. However, maximum plant growth and tomato yields (68 t ha-1) and economic benefits (benefit: cost ratio 6.9) were achieved with 4 t ha-1 CPM amendment and 100% recommended doses of NPK fertilizers. Control treatment (T1: -CPM, -NPK) had the lowest tomato yield (6.2 t ha-1). Composted poultry manure alone contributed for around 15.0 t ha-1 tomato yield and supplemented for around 30 kg ha-1 N fertilizer. Combine application of 4 t ha-1 CPM and 100% RDF of NPK fertilizers indicated as the agreeable combination in this study for optimal tomato plant growth and yield under rooftop growing conditions.

Thirty-seven pearl millet genotypes were evaluated for morphometric traits and disease incidence and severity during summer and kharif, 2022. Pooled ANOVA revealed significant variation were present in all genotypes across different season. Association studies identified high positive correlations between grain yield and traits such as single earhead weight, single ear head threshed weight, and test weight, with direct and indirect effects on grain yield through key characters. E2 (kharif – 2022) showed favourable conducive weather parameters for disease infection throughout the growing season compared to E1. The higher PCV relative to GCV for disease incidence underscores the environmental influence in disease resistance programs. Negative correlations between disease metrics and yield traits highlight blast disease’s detrimental effect on grain yield. Disease severity indirectly suggests environmental factors may enhance its impact. Disease incidence exhibited a direct negative impact on yield, supported by negative genotypic correlations. The line, PT 6679, exhibit both high yield and highly resistant to blast. Restorer lines (PT 6029, PT 6067, PT 6300, PT 6707, PT 7068) and B lines (ICMB 01666, ICMB 02777) showed promising yield attributes with high to moderate disease resistant for future breeding programs. In D2 analysis, five clusters revealed distinct genetic diversity with Clusters II and V indicating strong hybrid vigor, while Clusters IV (PT 6946, ICMB 06111) and V (ICMB 93111, ICMB 95444) excelled in disease resistance. Clusters I (PT 6029, PT 7068) and II (GMR 58) exhibited superior grain yield, particularly Cluster I, had potential restorer lines for future breeding. Clear differentiation between B and R lines underscored genetic distinctions in trait expression, validating the use of morphological data for assessing genetic diversity.
在 2022 年夏季和秋季，对 37 个珍珠粟基因型的形态特征、病害发生率和严重程度进行了评估。汇总方差分析显示，所有基因型在不同季节都存在显著差异。关联研究发现，谷物产量与单穗重、单穗脱粒重和测试重等性状之间存在高度正相关，主要性状对谷物产量有直接或间接的影响。与 E1 相比，E2（喀里多尼亚-2022 年）在整个生长季节都表现出有利于病害感染的天气参数。病害发生率的 PCV 相对于 GCV 较高，凸显了环境对抗病计划的影响。病害指标与产量性状之间的负相关突出表明了稻瘟病对谷物产量的不利影响。病害严重程度间接表明环境因素可能会增强其影响。病害发生率对产量有直接的负面影响，并得到基因型负相关的支持。PT 6679 这个品系既高产又高度抗病。恢复系（PT 6029、PT 6067、PT 6300、PT 6707、PT 7068）和 B 系（ICMB 01666、ICMB 02777）表现出高至中等抗病的产量属性，有望用于未来的育种计划。在 D2 分析中，五个聚类显示出明显的遗传多样性，聚类 II 和聚类 V 显示出较强的杂交活力，而聚类 IV（PT 6946、ICMB 06111）和聚类 V（ICMB 93111、ICMB 95444）则在抗病性方面表现突出。第 I 组（PT 6029、PT 7068）和第 II 组（GMR 58）表现出优异的谷物产量，尤其是第 I 组，有可能成为未来育种的恢复系。B 品系和 R 品系之间的明显区分突出了性状表达的遗传差异，验证了利用形态学数据评估遗传多样性的有效性。

Rhynchostylis retusa (Orchidaceae) is an important ethnomedicinal herb in Indian systems of medicine. Tribal healers commonly employ the roots of this epiphytic orchid to treat various ailments. In the present study, the shade-dried root powder of R. retusa was subjected to cold extraction with four solvents, such as n-hexane, acetone, ethyl acetate, and methanol. The crude root extracts were then taken for qualitative phytochemical screening. Furthermore, GC-MS analysis of ethyl acetate and methanol root extracts was carried out. The methanol root extract of R. retusa showed a positive result for all the phytochemicals tested except for saponins. GC-MS analysis of R. retusa methanol root extract revealed the presence of 16 phytoconstituents. Major phytoconstituents such as 9-Hexadecenoic acid, methyl ester, [Z] Heptadecanoic acid, 16-methyl-, methyl ester, Ethanone,1-[4-(4-morpholyl benzylidene amino)phenyl]-, are recorded in the methanol root extract. In the present study, both methanol and ethyl acetate root extracts showed the presence of9-Hexadecenoic acid, methyl ester, [Z] as the major phytocompound. The phytocompounds identified in methanol and ethyl acetate root extracts exhibit various biological activities, including anti-inflammatory, antibacterial, antifungal, antioxidant, and anticancer properties. Based on the findings of the current study, it can be inferred that the roots of R. retusa contain diverse bioactive compounds with medicinal properties. Further investigation of these R. retusa root extracts holds the potential for the discovery and development of innovative pharmaceuticals.

Polygonum tinctorium has long been employed in the medical and dye industries in many nations, particularly in Korea and Japan, for traditional fabric staining as a source of blue color. The plant tissue culture method has proven to be a rapid and sustainable approach for the regeneration of various plant species, particularly those with medicinal or ornamental value. In this study, we explored the in vitro root regeneration and growth of P. tinctorium in response to different growth media and gelling agents. Among the tested media, Schenk and Hildebrandt medium (SH medium) demonstrated superior performance, resulting in the highest number and length of roots per explant. SH media produced about 53 and 18% higher root per explant and a 40% and 14% increase in root length compared to B5 and MS media, respectively. Half strength of SH medium proved to be the optimal condition for both root number (7.46 roots per explant) and root length (3.81 mm). Among the gelling agents, 2 g/L of Gelrite medium was most effective in promoting the highest and tallest roots. These findings have the potential to enhance rooting abilities in various crops, particularly in the case of medicinal and ornamental plants, and may offer valuable insights for future industrial-scale root production of P. tinctorium.

SH media produced about 53 and 18% higher root per explant and a 40% and 14% increase in root length compared to B5 and MS media, respectively. Half strength of SH medium proved to be the optimal condition for both root number (7.46 roots per explant) and root length (3.81 mm). Among the gelling agents, 2 g/L of Gelrite medium was most effective in promoting the highest and tallest roots. These findings have the potential to enhance rooting abilities in various crops, particularly in the case of medicinal and ornamental plants, and may offer valuable insights for future industrial-scale root production of P. tinctorium.

Ecosystems have been affected by climate change. Both agriculture and environmental changes are correlated with various features since climate change is the main cause of abiotic and biotic stress, which affects crop plants. Climate change and its severe impact on plant productivity showed great intensity due to the effects of abiotic stress. In the present investigation, we selected two quinoa varieties to study the response to future climatic factors such as eCO2, enhanced UVB radiation, and UVB+eCO2 combined effects in open-top chambers in the hot climate of the UAE. The treatments were administered for 90 days in the hot UAE weather conditions and the experiment was carried out in a transparent OTC facility. The response of the studied quinoa varieties was measured by analyzing their non-enzymatic antioxidant and antioxidant enzyme activities. Our findings showed that quinoa varieties are suitable as industrial crops for their levels of antioxidants under stimulating climatic conditions because the quantity and quality of their yield have not been affected. Based on the results obtained in the present investigation, further study is warranted for screening more varieties with the addition of climate change factors such as temperature and humidity to find more tolerant varieties of quinoa suitable for future climatic conditions.

Urtica hyperborea Jacquem. ex Wedd., a perennial plant of Urticaceae family is considered as a wild vegetable in the mountainous region of Ladakh. Due to its application in many forms of traditional culinary in every household during the harsh winter season, the plant ensures the food security. However, the nutritional composition and phytochemical analysis of U. hyperborea responsible for these beneficial features have not been explored widely. The present study aims to determine the nutritional composition (e.g., macromolecules, pigments, minerals, phenolics and flavonoid contents), antioxidant activity and the phytochemical analysis of this plant species present in Ladakh, India. The radical scavenging and antioxidant potential of the plant were evaluated by assays like 2,2‒diphenyl‒1‒picrylhydrazyl (DPPH), hydrogen peroxide (H2O2), hydroxyl (ºOH), and ferric ion reducing antioxidant power (FRAP) for different extracts prepared in water, methanol, ethyl acetate, and petroleum ether. Macromolecules such as protein, carbohydrate, total phenolic and flavonoid contents in U. hyperborea were found to be 62.28±6.67, 170.80±3.98, 24.47±0.39 and 5.43±0.97 mg g-1, respectively. Similarly, dried powder of U. hyperborea was found to be rich in different mineral contents such as potassium, magnesium, sodium, manganese, zinc and iron. Among the various solvents used for exploring scavenging and antioxidant potential, aqueous extracts showed highest activity with 79.2% in DPPH assay as compared to other extracts. Similar trend was observed for other assays where aqueous extracts exhibited higher activity followed by methanolic, ethyl acetate and petroleum ether extracts. Significant positive linear correlations were observed between the radical scavenging/antioxidant activity of aqueous extracts and their content of phenolic/flavonoid compounds. The identification of phenolic compounds such as coumarin, quercetin, and ferulic acid confirm the antioxidative nature of the plant. Overall, rich macromolecule and mineral contents, as well as higher radical scavenging/antioxidant activities in aqueous extracts of U. hyperborea revealed that the plant has significant potential to be utilized as a phytofood source in harsh environmental conditions.

The application of leaf extract to synthesize nanoparticles has been taken as a green method. In this study, the potential for synthesizing zinc oxide nanoparticles (ZnO NPs) from Clausena anisata Hook.f. ex Benth. leaf extract was investigated. The source of zinc was zinc nitrate hexahydrate (Zn(NO3)2.6H2O). The characterization study was done by Ultraviolet–visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), Transmission electron microscope (TEM) and atomic force microscopy (AFM). The crystalline shape of nanoparticles is disclosed inside the XRD result, morphology is confirmed through SEM effects, and consequently, the ZnO NPs scale was predicted. ZnO NPs were synthesized to work against Sitophilus zeamais adults. A mortality count was carried out in 14 days and all the 3 dosages (0.2 g, 0.4 g and 0.6 g) were effective in killing S. zeamais. F1 progeny emergence was highly reduced in comparison to untreated control. Maize seeds were successfully germinated after treatment application with ZnO NPs.
