The present study aimed to characterize Fusarium species isolated from three different regions of cucumber fields in Babylon province, Iraq and identify them based on morphological features and phylogenetic analyses. This study showed the presence of Fusarium incarnatum, F. solani and F. oxysporum in cucumber roots. Fusarium species were phylogenetically analyzed based on internal transcribed spacer (ITS) regions. All Fusarium isolates were pathogenic to cucumber cultivars but varied significantly in their growth and pathogenicity toward cucumber seeds during the experiment.  F. solani-2 was greater in growth and pathogenicity than all other Fusarium species. In contrast, F. solani-1 was the lowest. The data obtained from morphological and molecular studies sufficiently supported each other, and the phylogenetic trees based on ITS were distinguished. Closely related species and distinctly separated all morphological taxa. These findings are reported for the first time for the cucumber plant in Babylon province. All these ITS sequences showed homologous to those of Fusarium species isolates in the GenBank database with a similarity percentage of 99%. To the best of present knowledge, this is the first molecular record of F. incarnatum on the cucumber plants in Iraq. The study concluded that F. incarnatum was reported for the first time in Iraq and worldwide as a causal agent of wilt disease in cucumber plants. The three species of Fusarium have different pathogenic abilities, highlighting their disease incidence, growth, and pathogenicity. \u0000 ","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":" 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140388189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This results in changes in land cover from vegetation to artificial material. As a result, much of the land surface reflects the sun's energy. Consequently, this increases the surface temperature of the land. An increase in land surface temperature (LST) will increase the intensity of rainfall. Therefore, the present study aimed to investigate the relationship between the increase in LST and rainfall intensity. Changes in land cover can be detected by normalized difference vegetation index (NDVI) and normalized difference built-up index (NDBI) parameters. Landsat satellite imagery was used to detect NDVI, NDBI, and LST. Image processing was done for imageries scanned in 1995, 2015, 2017, and 2021. Two areas in the East Java Province of Indonesia, namely Malang City and Pasuruan Area, were selected. The daily rainfall intensity data were collected from related rainfall stations in the same year. The Mononobe method was applied to analyze hourly and minute rainfall intensity. IDF curves were drawn from the analyzed results. The relationship between both parameters was analyzed by comparing the LST and hourly rainfall intensity from the IDF curve. The studied results showed that the maximum temperature increase from 1995 to 2021 for the Malang City and Pasuruan Area was 2.60 C and 7.60 C, respectively. For rain, the maximum rainfall intensity increased by 58 mm for Malang City and 18 mm for the Pasuruan Area. LST and rainfall intensity change trends of the two areas had a positive coefficient of regression. The findings can be used to predict the rainfall intensity and floods based on the LST data.\u0000 ","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":" 46","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140388482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanization of cotton harvest is increasing, but a substantial amount of foliage that remains on the plant even at maturity is the major barrier for mechanical harvest. Properly completing mechanical and manual harvests requires artificial leaf detachment through defoliants. Still there is no proper defoliant concentration, application times and mechanism of action available. Therefore, the present study aimed to find an effective defoliant and application time to enhance mechanical harvest efficiency, along with a clear description of the mechanism of actions in cotton CO17 (Gossypium hirsutum). The field experiment was conducted during the year 2019-20 and used five concentrations of Thidiazuron defoliant (100, 150, 200, 250 and 300ppm) and Ethephon@0.5% (T2) in cotton variety CO17 to study the physiological, biochemical and hormonal responses at 120, 127 and 134 days after sowing. As a result, the concentrations of plant growth hormones, indole-3 acetic acid (4.9 fold), zeatin (32.7%) and gibberellic acid (7 fold) reduced. In contrast, abscisic acid (48.6%), jasmonic acid (34.9%), salicylic acid (2.15 fold) increased in the T7- Thidiazuron + Diuron (300 ppm) treatment followed by T5-Thidiazuron + Diuron (200 ppm). Additionally, the antioxidant enzymes ascorbate peroxidase, peroxidase, catalase, superoxide dismutase, cellulase in leaves, petiole and bolls were decreased due to defoliant T5- Thidiazuron + Diuron (200 ppm) followed by T7-Thidiazuron + Diuron (300 ppm), indicating that the hormone concentration, antioxidative and hydrolytic enzymes are ruled out and forces the defoliation process.\u0000 ","PeriodicalId":14996,"journal":{"name":"Journal of Applied and Natural Science","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140388970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to examine the divergence, correlation and path analysis across 55 okra (Abelmoschus esculentus (L.) germplasms for 17 traits during the summer season (March- July) of 2022. The experiment utilized randomized complete block design with three replications conducted in Phagwara, Punjab.  Analysis of variance suggested a sufficient amount of genetic variation was found among all genotypes. Using Mahalanobis D2 analysis, the samples were classified into seven clusters, the largest being cluster I, composing 34 germplasm. Only one germplasm was found in Clusters II, IV, V, VI, and VII. The inter-cluster distance was highest between clusters II and VII, whereas the intra-cluster distance was greatest in Cluster III. The number of fruits per plant had the highest percent contribution to the divergence, accounting for 49.63%. At both phenotypic and genotypic levels, there was a strong positive correlation (+) observed between fruit yield and various characteristics, including plant height, fruit length, number of fruits per plant, number of marketable fruits per plant, average fruit weight, and the number of pickings. Genotypic path analysis revealed that characteristics such as the first flowering node, days to first flowering, days to 50% flowering, plant height, inter-nodal length, number of nodes per plant, number of fruits per plant, marketable fruits per plant, and average fruit weight exhibited a positive and direct effect on fruit yield. When selecting this trait to improve yield in okra through breeding, it is essential to focus on specific characteristics that directly contribute to higher production.

This study focuses on the molecular identification and phylogenetic analysis of the Alternaria perpunctulata strain GVKNSV7, which is responsible for leaf spot disease on A. philoxeroides. Diseased plant leaves were collected from Kakumanu Mandal, Guntur, and local vegetable markets of Visakhapatnam, Andhra Pradesh, India, in December 2021, revealing symptomatic samples with pink to reddish spots on A. philoxeroides leaves. Employing a comprehensive approach that included morphological assessment, pathogenicity testing, and ITS region sequencing, the isolated fungus was conclusively identified as A. perpunctulata with a high sequence similarity of 98.54%. Molecular comparison with sequences in the NCBI database further validated this identification. The resulting genetic sequence, formally catalogued as \"Alternaria perpunctulata GVKNSV7,\" with the GenBank accession number OQ073752, has been successfully submitted to the NCBI database. This study emphasized the utility of ITS sequencing and molecular analyses for accurately identifying and documenting emerging pathogens. Such documentation provides essential insights for developing future bioherbicides and effective weed management strategies. Furthermore, it highlights the potential use of A. philoxeroides as a leafy vegetable, contributing to food security and agricultural sustainability.

Contamination is initiated in explants excised from soil-borne tissues or adult trees. Several sterilizing agents (Tween 20, chlorine water, silver nitrate, mercuric chloride, etc.) or a wash in antibiotic solution are recommended to reduce this. . Establishing in vitro cultures of Acacia nilotica old tree nodal explants was a serious problem. The present study was undertaken to create a suitable protocol for in vitro micropropagation of nodal explants of Acacia nilotica subsp. indica. Contamination was controlled by sterilizing the explants by washing in polysan (5%, v/v along with 500mg/l PVP), thorough washing under tap water, 70% alcohol treatment and 0.1% HgCl2 treatment. Plant tissues release phenolic substances through their cut ends, which turn the media dark brown and toxic. Addition of various antioxidants or/and transfer of explants to fresh medium twice or thrice, at a few days’ intervals may overcome the problem.  Collection of explants in antioxidant solution and a wash in antioxidant solution prior to inoculation was helpful in reducing the phenolic exudation in the present investigations.  The addition of antioxidant (citric acid) to the medium also checked browning to some extent. The rate of infection and browning of explants varied in different seasons, the maximum being during winters and the minimum during summers of 2019.
