Multivariate analysis in Wheat (Triticum aestivum L.)
The goal of the current study was to use eighty-four genotypes for multivariate analysis in wheat. These genotypes might be divided into eleven clusters based on the degree of genetic difference. Cluster VI, Cluster V, and Cluster III had the largest intra-cluster distances based on maximal diversity, indicating that these genotypes may be easily able to manipulate traits to enhance wheat. Because cluster I had a single genotype cluster, it had the lowest intra-cluster distance (0.00). Between clusters II & V, II & VI, and V & VI, the greatest inter-cluster distance was discovered. Low cluster means for the genotypes KRL-35, KRL-99, and LBRIL-102 showed that these genotypes differ genetically from the other genotypes, especially with regard to yield and attributes associated to yield. As a result, this genotype may be recognized as a reliable and beneficial donor for raising wheat grain production. UP-2938, UP-2903, HPW-368, HPW-360, DBW-328, PBW-821, PBW-752, UP-3043, WH-1270, VL-3021, GW-509, HD-3343, MP-1358, DBW-332, VL-3022, HPW-373, NW-2036 & NW-1076, on the other hand, may result in better heterotic response and recovery of better segregants in the early generations for an increase in wheat yield via these component traits. In terms of cluster mean, cluster distance, and the percentage contribution of each trait, genotypes from clusters II, III, V, VI, VII, and IX would be promising to employ as hybridization programme breeding material.
Study of urban trees characteristics in the Northeast of Algeria in the face of climate change
Climate change is having a significant impact on urban trees in the Northeast region of Algeria. As temperatures rise and precipitation patterns shift, trees are facing new challenges that require careful study and management. One key characteristic of urban trees in the face of climate change is their ability to adapt to changing conditions. Some tree species are more resilient to heat and drought, while others may struggle to survive in a changing climate. Understanding which species are best suited to the local environment is crucial for ensuring the long-term health and survival of urban trees. Another important characteristic is the role of urban trees in mitigating the effects of climate change. Our work aims to show whether the structure of trees is influenced by environmental factors, focusing on the main phenological phases of trees in urban areas. The methodology involves taking dendrometric measurements for different trees and shrubs in five locations where three plots are in urban state and two plots are in two different garden in the Mediterranean urban area, as well as monitoring the main phenological phases for certain species. Statistical analysis of the data showed a significant difference in dendrometric measurements, which varied from one location to another. The health status of the trees also varied from one location to another, illustrating the effect of local conditions on vegetation development. Climate change, particularly the increase in temperatures in January and February and snowfall in March, causes vegetation to behave differently than before.
Effect of Garlic Aqueous Extract On Lead Acetate- Induced Developmental Neurotoxicity in Zebrafish Model
The toxic heavy metal lead is non-biodegradable and accumulates through the food chain which can cause hazardous effects to livestock and human health. The zebrafish that has recently attained a pre-eminent position in biomedical research is considered an ideal model for assessing the developmental toxicity. Garlic, Allium sativum L. has been used widely for treating various diseases. Hence in this study, the effect of garlic aqueous extract on lead acetate induced developmental toxicity in zebrafish embryos/larvae was assessed. Normally dividing 5 hpf (hours post-fertilization) embryos were allotted into different groups, in six well plates. Two control groups were used one with plain embryo water and the other with garlic aqueous extract. Lead acetate (LA) was exposed at three dose levels 0.1, 0.5 and 1 ppm to the next three groups. The other three groups were exposed to lead acetate at the above mentioned three levels along with 1 µg garlic aqueous extract (GAE). Hatchability and aberration percentage were estimated. Apoptosis and histopathological study were done. Lead induces dose dependent developmental toxicity in zebrafish embryos/larvae. GAE has a limited protective effect on lead acetate treated embryos. The protective effect of GAE was better in the 0.1 ppm lead acetate exposed group followed by 0.5 and 1.0 ppm lead acetate treated groups respectively.

Physio-biochemical response of wheat to various treatments of nanoparticles under moisture stress (Drought) conditions
The study titled "Physio-biochemical response of wheat to different nanoparticle treatments under moisture stress (drought) conditions" was carried out during the Rabi season of 2022-23 and 2023-24 at the student instructional farm (SIF) of Acharya Narendra Deva University of Agriculture and Technology, located in Kumarganj, Ayodhya- 224229 (U.P.). The experiment was carried out using a randomized block design, with three replications and ten treatments, using the wheat variety HD 2967. The treatments consisted of the following: T1: control (foliar spray of distilled water), T2: Ca3PO4 (40ppm), T3: TiO2 (40ppm), T4: TiO2 (40ppm) + Ca3PO4 (40ppm), T5: TiO2 (50ppm). T6: TiO2 (50ppm) + Ca3PO4 (40ppm), T7: ZnO (40ppm), T8: ZnO (40ppm) + Ca3PO4 (40ppm), T9: ZnO (50ppm), T10: ZnO (50ppm) + Ca3PO4 (40ppm). The application of foliar spray occurred 45 days after sowing (DAS). The physio-biochemical parameters were measured at 60, 75, and 90 days after sowing (DAS), whereas the yield data was recorded at harvest time. The application of foliar spray containing both ZnO and TiO2 nanoparticles, as well as Ca3PO4, was found to be highly successful in reducing moisture stress compared to the control group. The addition of Nano ZnO at a concentration of 50ppm, combined with Ca3PO4 at a concentration of 40ppm (T10), was shown to be the most efficient in increasing both the total chlorophyll content and total soluble sugar content under conditions of moisture stress. This treatment was followed by treatment T9. However, when considering additional characteristics such as membrane stability index (MSI), relative water content (RWC), grain yield, and biological yield, treatment T9 showed significantly greater values than the control treatment for the crop. Treatment T4 also showed higher values, although to a lesser extent. The current study concludes that nanoparticles effectively reduce moisture stress in wheat. Specifically, ZnO (50ppm) followed by TiO2 (40ppm) in combination with Ca3PO4 (40ppm) are recommended treatments to alleviate the negative impacts of moisture stress on wheat crops.
Phytochemical and microbiological evaluation of Buxus dioica from the Bougtob region, Elbayadh Province Algeria
Traditional medicine has always held a significant place in Algerian medication traditions. This thesis contributes to the study of the biological activities of Buxus dioica. The preparation of various extracts was followed by phytochemical screening. Subsequently, an evaluation of antioxidant activity (total capacity and DPPH scavenging) and antimicrobial activity (solid medium diffusion) was conducted. Three extracts were prepared: methanolic, ethanolic (macerated), and aqueous (infused) extracts. The results showed that the aqueous extract had the highest yield at 9.3% among the studied extracts. Phytochemical screening revealed the presence of various secondary metabolites (tannins, flavonoids, saponins, and starch). The evaluation of antioxidant activity revealed that this plant has excellent antioxidant properties, with a percentage of 92% and an IC50 of approximately 2.01 mg/ml. Microorganism sensitivity tests showed that Candida albicans ATCC 10231 A14 was the most sensitive to the methanolic extract (22 mm) by the solid medium diffusion method.
