Hydrogen peroxide (H2O2) and malondialdehyde (MDA) content was reduced in Cd+SS (50 µM CdCl2 primed followed by 200 mM NaCl treatment) tissues as compared to salt stressed (SS) tissues. The activities of superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), and guaicol peroxidase (GPX) were increased in Cd+SS tissues as compared to SS tissues. Moreover, the concentrations of ascorbic acid (ASC) and proline were also increased in Cd+SS tissues as compared to SS tissues. Thus, a low dose Cd priming provided tolerance to pigeon pea seedlings by activating the antioxidant machinery.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117332554","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}

On the other hand, Local cultivars bloom earlier when planted later than the advised date. Due to the heat, it cannot be grown throughout the summer. Pushing the somatic cells to divide and create a new polarity is necessary for the induction of tissues in the lab and the creation of somatic embryos. It was shown that several auxins play a crucial role in the development of these embryos, particularly 2, 4-D (2,4-dichlorophenoxyacetic acid). This experiment was carried out to investigate the effect of five procedures in a tissue culture laboratory using two concentrations of 2, 4-D at a concentration of 2.5 and 5 mg/l for indirect somatic embryos induction from sexual embryos produced from culturing carrot  (Daucus carota) seeds of Carrot cv. Kuroda (an heirloom variety). The results confirmed by scanning electron microscopy showed that it is crucial to compare the various processes used to create somatic Embryogenesis to assess their effectiveness. The four stages of somatic embryos, globular, heart, torpedo, and cotyledon form, were observed on the formed callus. The highest amounts of callus fresh weight, the number of globular-shaped stage embryos, the number of heart-shaped stage embryos, the number of torpedo-shaped stage embryos, the number of cotyledon-shaped stage embryos, and the number of seedlings had been recorded in the media supplemented with 2, 4-D at a concentration of 5 mg. This study was able to produce somatic embryos of the foreign carrot cv.

Nuclear technology has emerged as a valuable tool for enhancing agricultural productivity. Despite the common association of nuclear technology with energy and weaponry, its use in Horticulture is diverse and multifaceted. Physical mutagens such as nuclear radiation, including gamma rays, X-rays, and UV light, as well as particle radiation, can be employed to induce chromosomal breakages, cross-linking of DNA strands, nucleotide deletion, and substitution. UV rays can be used to irradiate cell suspensions and pollen grains in the early or late uninucleate phases. Through the application of nuclear technology, agricultural productivity can be improved by increasing crop yields, controlling pests and diseases, and enhancing water quality. Food preservation can also be achieved through food irradiation, where ionizing radiation is applied to target pathogens to break their DNA bonds. Nuclear technology can also be utilized to induce beneficial mutations in crops through genetic modification, sterilization-based pest control, and water usage management. In conclusion, nuclear technology presents an innovative and effective solution for addressing challenges in Horticulture, thus contributing significantly to global food security.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125486135","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 experimental results showed that breadfruit root cuttings in the filter media were better for shoot height, number of leaves, leaf area and root volume compared to sawdust and rice husk media. A low concentration of 2.4 D (1.0 mL.L-1 water) showed better growth of shoot height and number of leaves than higher concentrations. The interaction of filter cake media and low concentration of 2.4 D (1.0 mL.L-1 water) had a significant effect on the sprouting rate of breadfruit root cuttings.

These plants are resilient to various environmental challenges; they are also one of the most efficient terrestrial and coastal ecosystem for carbon fixation and storage. In recent years, mangrove reforestation has attracted much attention as a strategy to reduce the effects of climate change. In Egypt, there are two types of mangroves, Rhizophora mucronata and Avicennia marina, between 30°N and 30°S of the equator. Mangrove management presents a difficult task, particularly when it comes to managing molecular mangroves for long-term sustainability. With the impact of human activity on mangrove ecosystems increasing each year, molecular research on mangrove correlates remains to be conducted. For this reason, using DNA barcoding technology to quickly identify species, mangrove ecosystems may be protected. \u0000Methodology: In this work, the two Egyptian mangrove species were assessed through morphological, cytological, and molecular approaches. Two universal DNA barcodes, rbcL and ITS, were examined to identify their efficacy for Egyptian mangrove species identification and phylogenetic reconstruction. \u0000Results: According to pairwise alignments, the rbcL region had the highest level of variability (73.2%), whereas the ITS region was the least variable (11.96%). The selected Egyptian mangrove species can potentially be distinguished by barcoding loci rbcL and ITS due to the existence of distinctive variable sites.","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129496694","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 experimental design was a randomized complete block containing seven treatments with three replicates. Seeds of peas were sown in the 2nd week of September during the two winter growing seasons. \u0000The results showed that, the most estimated parameters were significantly affected with all tested treatments as foliar applications; the superiority effect of the treatments was recorded by using kaolin (Aluminum silicate) followed by selenium element and green miracle which led to obtain the highest significant increase in all the previous studied traits i.e. the vegetative growth, green pods yield, dry seed yield and its components as well as seed quality under high temperature stress conditions. The superior treatment; kaolin at the rate of 20 g/ L increased green pod yield by 36.8 and 33.6 % and enhanced dry seed yield /fed by 34.2 and 32.3 % over the control treatment (the untreated plants) in the two winter seasons, respectively. ","PeriodicalId":298912,"journal":{"name":"Asian Journal of Agricultural and Horticultural Research","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127585328","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}
