Wheat rust is a common disease, caused by parasitic fungus and reduces crop yield up to 30 to 40 percent by effecting leaf and stem of plant. The wheat seed having fungus are the carrier of rust infection for the plant. The infected seed and rust fungus not only reduce food quantity but effect its quality. In our experimental research, the wheat leaf sample of day 10, 27, 35 and 45 were analyzed. The rust appears after day 24 on leaf, and rusted leaf has higher surface roughness than the normal one. We analyzed shape, surface structure of normal and rusted wheat leaf surface with AFM. The leaf protein and structure with high-resolution AFM imaging under controlled environmental conditions. The results revealed the morphological details of normal and viral infected proteins of wheat leaf with high-resolution in vivo study. The findings provide the basis for AFM as a useful tool for investigating microbial-surface structures and properties at an early stage of rust. We can visualize the starch granule surface at different stages of maturity reveals information regarding the development of granule architecture. The changes in infected leaf compared to normal can be seen at starch granule interior throughout the growth. Leaf surface shows depressions on the granule surface and changes in protein for the infected, and we can manage the disease at an early stage of rust development. These results will be used for an early stage detection of wheat rust and can be extended to other crops diseases detection using AFM and laser-scanning microscopy.","PeriodicalId":268857,"journal":{"name":"Open Access Journal of Environmental and Soil Sciences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123592570","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 San Justo Training and Demonstration Center is a complex of plots containing a great diversity of vegetables and management methods in the same site, allowing a joint analysis on the effect of different management practices on plant communities. In this sense, the objectives of this work were: 1) To analyze the weed communities in the areas adjacent to the plots destined to different uses in Buenos Aires and 2) To evaluate the degree of maturity of the vegetal communities and different uses in urban horticulture garden. Surveys were carried out in three sectors of the site coinciding with the edges of the plots of the demonstration center. The variables measured were frequency, floristic diversity or richness, coverage of each species and total community coverage in relation to each use (semi-covered fallow, weeding, intensive horticulture and artificial trees). The plot with semi-covered fallow presented a higher frequency of appearance of Lolium multiflorum and Trifolium Repens. In horticultural use a high frequency of Oxalis latifolia and Taraxacum officinale is observed, both species are fertile soil indicators. Lolium multiflorum were found as dominant (in number of individuals) in almost all the samplings. When the disturbances are reduced or are practically zero, the appearance of perennial species is observed, demonstrating a greater advance in the succession process.","PeriodicalId":268857,"journal":{"name":"Open Access Journal of Environmental and Soil Sciences","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122744223","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}

Characterized by the process of sowing perennial legume grasses, improving the nutritional regime of the soil, activating nitrification, microbiological processes and preventing soil erosion. The â€œgreenhouse effectâ€ is a natural phenomenon in which certain gases in the lower atmosphere prevent some of the heat energy radiated from the Earth from escaping. The human-caused emissions of greenhouse gases (CO2, methane, nitrous oxide, and some industrial gases) have over the last few centuries added to this effect, making global temperatures warmer than they would otherwise be and affecting global weather patterns. â€¢ The hole in the ozone layer is a separate phenomenon, but there are a few linkages with the greenhouse effect. For example, some gases which deplete ozone in the upper atmosphere (CFCs) also act as greenhouse gases in the lower atmosphere, and the trapping of heat in the lower atmosphere by the greenhouse effect leads to a cooler upper atmosphere and a slower recovery time for the ozone layer.","PeriodicalId":268857,"journal":{"name":"Open Access Journal of Environmental and Soil Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126744108","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}
