(Giza 15 - G15 and Dorado - Dor) under two salinity levels (100 mM and 200 mM NaCl). Results revealed that salinity reduced various growth criteria, including insoluble and total carbohydrates, photosynthetic pigments, protein, total phenols, and reduced glutathione, while soluble carbohydrates (sucrose and trehalose) were influenced. Salinity also affected free amino acids (proline and glycine betaine), malondialdehyde, and ascorbic acid. The activity of amylase decreased, while antioxidant enzymes (catalase, peroxidase, superoxide dismutase, ascorbic acid oxidase, and glutathione peroxidase) increased. Additionally, concentrations of K+, Ca++, and Mg++ were reduced, while Na+ accumulated. Application of Callistemon extract improved plant growth under stressed or normal growth conditions. The aqueous leaf extract (0.09%) of Callissstemon sp., with its enriched phenolic allelochemicals, mitigated the impact of salinity by enhancing photosynthesis, osmoregulation, and the antioxidant defense system of sorghum plants. Furthermore, results indicated that Sorghum cultivar G15 exhibited more resistance than Dor, with this resistance correlating with the activity of the antioxidant system.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140962253","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 field study was laid out in split plot design with three replications. Three rice cultivars (Giza 177, Giza 179 and Sakha 108) were randomly distributed in main plots, while weed control treatments included four herbicides at recommended doses (penoxsulam 2.5% OD, bispyribac-sodium 2% SL, cyhalofop-butyl 10% EC and fenoxaprop-p-ethyl 7.5% EW) as compared to hand weeding were devoted in sub plots.

The research work entitled “Effect of Bacillus pumilus strains on heavy metal accumulation in lettuce grown on contaminated soil” focuses on functional role of Bacillus pumilus strains inoculated with lettuce seed in mitigating heavy metal present in chromite mining soil. This experiment was conducted at ornamental horticulture nursery, the University of Agriculture Peshawar. In this experiment, factor A was three Bacillus pumilus strains (sequence C-2PMW-8, C-1 SSK-8 and C-1 PWK-7) while soil used for this experiment was collected from Prang Ghar mining site and lettuce seeds were grown in three levels of chromite mining soil (2.27, 4.65 and 7.14 %).The experimental design used during this research was randomized complete block design with two factors and was replicated thrice. The collected data related to effect of chromite mining soil and Bacillus pumilus strains indicated that these both factors have significant influence on growth parameters. For mining soil minimum days to germinate (14 days) was noted in lettuce grown on garden soil inoculated with sequence. Maximum germination percentage noted was (100%) for C-1 SSK-8 grown on garden soil, dry weight of lettuce leaf (5.0 g) for lettuce inoculated with C-1 SSK-8 and C-1 PWK-7 strains, survival percentage (77.9%) for C-1 SSK-8 treated lettuce for sequence C-2 PMW-8. Maximum germination percentage noted was (88%) for garden soil, fresh leaf weight (17.3g), dry leaf weight (6.5g), number of leaf per plant (16), leaf area (49.0 cm2) were noted in garden soil with no chromite mining soil. Results related to heavy metals accumulation showed that minimum chromium was (2.3 mg kg-1) in lettuce and (1.9 mg kg-1) in soil for all three sequences. It can be concluded that chromite mining soil significantly reduced the growth and survival of lettuce, but when lettuce was inoculated with Bacillus.pumilus strains it enhances the growth and survival. Similarly, minimum heavy metal accumulation in plant and soil, regardless of type of B. pumilus used, all three sequences has same mitigating effect on heavy metal in both soil and lettuce. All the three Bacillus pumilus strains ensured reduction in heavy metals content (Cr) in lettuce, below the maximum permissible limits of WHO/FAO 2011.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140716771","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}

Thus, instead of sticking to their long-standing diets of ordinary cereals and basic foods, individuals are starting to choose more intelligent and nutrient-dense dietary choices. Because they are gluten-free, have no added sugar, and are somewhat higher in nutrients than typical cereals, pseudocereals—particularly quinoa and amaranth—are significant substitutes. Both Amaranthaceae crops are hardy, low-input plants that can withstand salt, stress, and drought. Therefore, these crops might be advantageous to emerging nations with limited agricultural resources and subsistence agriculture. But these are neglected orphan crops, and for a very long time, there has been no attempt to enhance them by lowering their saponin content. These crops also have a great degree of variety, but their genetic development towards high-yielding genotypes is sluggish. This is because traditional cereals are facing problems, and crop diversification is the preferred solution to address climate change.

Despite its importance, potato production in Kenya is still low due to abiotic and biotic constraints. Traditional breeding and improvement have been difficult due to the narrow genetic diversity of the crop owed to the complex tetrasomic inheritance patterns. Induced mutation has been used to generate genetic variations in potato from which desired putative mutants are selected. In most cases the level of genetic variability is not known. The objective of this study was to determine the genetic variability of potato mutants using SSR markers.\u0000Study Design: The study involved three potato varieties; Asante, Kenya Mpya and Kenya Sherekea which are high yielding and commercially grown varieties in Kenya.\u0000Place and Duration of Study: Sample: They were irradiated at different dose rates of gamma rays at Co60 source at FAO/IAEA laboratories, Seiberdorf Austria in 2014. A total of 163 mutants were advanced to M1V4 generation at the University of Eldoret between 2015 and 2018.\u0000Methodology: Genomic DNA was extracted to assess the diversity with 20 SSRs markers.\u0000Results: All the 20 SSR primers were polymorphic with 6-19 bands amplified per primer and marker STM5127 showed the highest allele number (19) using PowerMarker software. The STRUCTURE analysis suggested that the potato mutants were clustered into six sub-populations based on the unweighted pair-group method of arithmetic averages (UPGMA) thus, the accessions were divided into three major clusters. Analysis of molecular variance (AMOVA) indicated that 8.6% of total molecular variance was attributed to diversity among sub-populations, while 91.4% of variance was associated with differences within sub-populations.\u0000Conclusion: This study highlights the most comprehensive investigation of the genetic diversity and population structure of potato mutants, and provides valuable information for genetic improvement, and systematic utilization.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140363351","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}
