Hexavalnet Chromium Case Study

1083 Words5 Pages

The present investigation was carried out with effect of hexavalnet chromium on seed germination, growth, yield, biochemical constituents, mineral contents and RAPD analysis of Tagetes erecta. In addition recompense on hexavalent chromium polluted soil by using suitable soil amendment of VAM(Arbuscular mycorrhiza) treatment was followed and their correspondent results have been given above mentioned parameters.
Germination percentage
The germination percentage, vigour index, tolerance index, toxicity level and percentage of phytotoxicity values of Cosmos bipinnatus, Tagetes erecta, Celosia cristata, and Gomphrena globosa were tabulated in table no. 1, 2, 3 and 4. The table. no 1,2,3, and 4 shows results of the germination percentage, vigour index, tolerance index, toxicity level and percentage of phytotoxicity revealed Tagetes erecta were found to be more potential against the effect of hexavalent chromium with treatment of VAM when compared to other three ornamental plant species. …show more content…

The without treatment of VAM considered as control plant, it gives very low germination percentage, vigour index, tolerance index, toxicity level and percentage of phytotoxicity compare than higher concentration of 25 gm/ kg of VAM and other respective concentration such as 5,10, and 15 gm/ kg-1 VAM of Hexavalent chromium polluted

    In this lab, the oxidation of a secondary alcohol was performed and analyzed. An environmentally friendly reagent, sodium hypochlorite, was used to oxidize the alcohol, and an IR spectrum was obtained in order to identify the starting compound and final product. The starting compound could have been one of four alcohols, cyclopentanol, cyclohexanol, 3-heptanol, or 2-heptanol. Since these were the only four initial compounds, the ketone obtained at the end of the experiment could only be one of four products, cyclopentanone, cyclohexanone, 3-heptanone, or 2-heptanone. In order to retrieve one of these ketones, first 1.75g of unknown D was obtained.

    As a result, plants have adapted ways to protect themselves against their natural predators by implementing “defense mechanisms”. Such adaptations may be structural or chemical, where structural mechanisms are simply parts of plant structural arrangement, such as thorns. Chemical defense mechanisms are more complex, and involve production of retarding chemical compounds and toxins. These volatile compounds are often released when the plant is damaged, and have physical effects on the predator.

    rapa our class planted Brassica Rapa seeds at high densities and low densities, the low density, with two seeds, and a high density with ten seeds into pots that were 400 mL. We added a conservative amount of water by sprinkling it, as well as fertilizer and then placed the pots on a rack under 40 watt lights. After 5 weeks, we harvested the plants and measured height and survivorship. We compared the height and survivorship between the high and low densities using an unpaired T-test in JMP. Results

    If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle

    Marigolds that have been exposed to high amounts of Cobalt 60 have been shown to grow with severe defects. The problem did not start with the flower’s blossoming, with its nourishment, or even with the surfacing of the first sprout. Before it was even planted, it was corrupted. The very seeds of the American Dream were sewn with prejudice, and yet we ask ourselves how its malformation came to be. The American Dream burgeoned in a time of xenophobia and sexism, and thus, its petals are laced with bias and corruption.
