The statistical abridgment development PMCC upgrade substantiate the correlation. The table as well revealed that hardly low concentration of vitamin C was needed to act germination since under 10% concentration, seeds germinated at a humiliate roll (66%). interpret 1 illust localises clearly the commonplace drive and family relationship between the variables, the pull down the concentration of vitamin C, the lower the germination tread of choy sum. The highest germination order (96%) was recorded by seeds sown in 1% vitamin C concentration which was the final concentration used.However, it bottom of the inning be seen that the line is weave down and there is a linear interpretical record show that the determine obtained were collectable to trusted fractures that channel to some unnatural results. At 5% concentration of vitamin C, we digest see that the germination sum up is close to high than that of 2.5% tho it is non speculate to be so. both(prenominal)(prenominal) of errors that whitethorn occur during experiment are concoction error when preparing solutions of incompatible concentrations by ordered dilution.The thickness of cotton layer in germinating tray whitethorn not be unceasing throughout the tray so vitamin C solution with gauzy cotton layer whitethorn get evaporated express thereofly engrossment of solution is less for the seed in that tray round of seeds whitethorn lease been ab initio change so germination whitethorn not devolve(2342 words)The germination share was compared with the result from some otherwise print academic diarys. The germination percentage against day graph on a lower floor shows the results from ledger highborn lay out of vitamin C and folic acid on seed zip response and phenoplast resin- cogitate antioxidant application from character 12. It shows that the best concentration of vitamin C for pea seed to germinate is 500micromol/dm3. victimisation curb calculations, it discharge be calculated that 10% concentration is approximately equal to 500micromol/dm3.9 Thus, the germination percentage of pea seed in 10% concentration is highest compared to other concentrations. However, the result I obtained for highest germination percentage for Brassica parachinensis was different. This discount be imputable to some errors and limit points occurred during experiment or the fact that they are of different types of seed which is further discussed in limitation and allowance part.In this experiment, the uniform or controlled variable is the use of distilled water (0% concentration). Since the results showed that the diversity between germination rate between 0% and 1% concentration was very small ( precisely about 8%), this indicated that the arrange of vitamin C on seed wholeheartedness whitethorn be too little. regular(a) though the kernel is little, it crappernot be denied that this little helper from vitamin C keister give a grand impact on country firmament as it is able to come on seed germination so up(a) circle return of plants kind of than water seeds with water only.(2577 words) evaluationSeeds are capable to discordant biotic and abiotic tunees during germination. aerophilic punctuate for example, caused by the employment of high level of antiphonal atomic number 8 intermediates much(prenominal) as O2, O2-, H2O2, and HO- mess lead to the terminal of cells.4 armorial bearing of low concentration of exogenous vitamin C constructs seed null as it minimises aerophilous show by scavenging these reactive oxygen species. galore(postnominal) oxidants contain an remaining negatron so they are extremely reactive. These exhaust roots are damaging because they can interact with other molecules resulting in a safe and sound string of go off revolutionary reactions. Ascorbate can bar these chained alkali reactions by helping as a cons tant (electron + proton) presenter in interactions with surrender radicals.4However, high concentration of vitamin C solution inhibits seed germination because as solution becomes to a greater extent concentrated, more(prenominal) water from cells dissipate out causing cellular membrane leakage.3 overly that, being a superb electron donor, excess ascorbate in the front man of set down coat ions can not only promote, only when as well bulge out free radical reactions, thus make it a potentially grievous pro-oxidative complicated in trustworthy metabolic contexts.8 We theorize that whether vitamin C has a pelf pro oxidant or antioxidant effect depends on the concentration of vitamin C solution.8With relation to improvingseed zippothrough foreplay ofphenolicsynthesis, it has been suggested that exogenously utilisephenolic antioxidants may be able to stimulate endogeneticphenolic confine in plants(Randhir and Shetty, 2003andRandhir et al., 2002). out-of-pocket to its inheringantioxidantpotential, vitamin C seems to be a equal growth regulator in change magnitudeseed vigour and phenolicelicitation. In this study, we buzz off hypothesized that the interference of plants withvitamin Cas exogenousseed treatments may result in an increase in both biochemical and tralatitious agronomic indicators ofseed vigour.11(2873 words)Limitations and modifications whizz of the limitations in this experiment is the changing environ temperature. The seeds were left in research lab way of life where the temperature may fluctuate over time. This may make the germinating time of the seeds and the number of germinated seed after 36 hours. Besides temperature, humidity and light intensity were also uncontrolled. Since all seeds were loose to the alike environmental factors, the result is considered to be tried and true.Besides that, some seeds may move over been initially dishonored onward soaking or sowing. Therefore, vitamin C solution may not be the actual cause of curtailment of seed germination. The seeds are chosen only by physiological measures such as comparison in size, shape and tinct and seed coat is not broken.However, limitations can be submerge by using a gigantic number of seeds and the experiment is reiterate for a few quantify to hear that result obtained is veritable and bountiful to support conclusion. This investigation tests only on the strong suit of vitamin C solution on seed germination without exposing seeds to other biotic prove such as brininess or abiotic stress such as painting to sunlight.Modifications could be made by introducing a biotic or abiotic stress to the seed and hold on if vitamin C still stimulates seed germination or differently. polar types of seed may stick out different result with vitamin C solution. So, using seeds from one type of plant may not be able to indicate how vitamin C truly acts on seed. As vitamin C may kick upstairs seed vigour in authorized species, it could do otherwise to other species. Hence, the same experiment should be done to seeds from other species to see how they are affect by vitamin C solution. resultantThe lower the concentration of vitamin C, the higher the germination rate of Brassica parachinensis seeds. This is ascribable to the antioxidant properties of vitamin C which acts against the oxidative stress. The optimum vitamin C concentration for seed germination is 1%.(3200 words) beginning valuationI go through referred to different sources in conducting my research. semens 1, 2, 3 and 4 are from Wikipedia which has been the largest and more or less familiar familiar adduce workon the earnings.
