Brassica rapa

characterise Brassica oleracea accessions. Among the 136 reproducible fragments generated, 25 (18.4%) fragments were common for all Brassica, 27 (19.9%) were unique and 84 (61.7%) were phylogenetically informative. Flannery et al. (2006) assessed polymorphisms in Brassica, Arabidopsis, Camelina, Raphanus and Sinapis using 10 plastid SSR primer sets. Eight loci were polymorphic, and separated the individuals of Brassicaceae into taxon-specific groups (Arabidopsis, Camelina, Sinapis and Brassica…

In an experiment conducted by students attending Michigan State University, they found that plants with a larger caffeine to water ratio grew less than the ones with more water than caffeine added. They used Wisconsin Fast Plants (Brassica Rapa) and gave them different concentrations of caffeine in order to see the effects. They hypothesized that adding significant amounts of caffeine to the plants would be detrimental to the growth of the plants. In the end, not only did their hypothesis prove…

gradient of oil contaminant, the superior root structure characteristic of an invasive plant species, Brassica rapa, will allow it to display a less significant decline in plant fitness in comparison to a native plant species, Tagetes patula (marigold). This rationale supports the following predictions: that, in the presence of an increasing concentration gradient of gasoline contaminant, Brassica rapa will display a greater increase in plant height, dry biomass and rate of leaf growth in…

From the experimental results, we have concluded watering rapid-cycling brassica rapa with Gatorade negatively affects growth. The growth difference was very obvious as seen in the results, as the tallest plant water with Gatorade grew only a fifth of what the smallest plant watered with water. However, it is unknown if the Gatorade directly affected the plant or had more affect on the soil. The soil was obviously affected by Gatorade, as the soil became tough and more rock like. The Gatorade…

Effect of Acid Rain on Wisconsin Fast Plants Introduction Acid rain has become a large environmental problem around the world. This chemically potent precipitation is incredibly common in large metropolitan cities where pollution and smog are prevalent. Acid rain has been known to diminish plant growth or completely kill off populations within the contracted areas of these large cities. In addition to effecting plants, it has also been determined that the pollutants in acid rain, such as heavy…

Mendel is often called the father of modern genetics. Mendel developed the theory of inheritance several decades before the observance of chromosomes via microscope. In Biology lab the past two weeks I completed a series of tests using fast plants, Brassica rapa. The objective of this experiment was to study the Mendelian laws of genetics as they applied to monohybrid and dihybrid crosses. I came up with two hypotheses said tests. The first being, the genetic trait of stem color is due to…

How will acid rain affect the growth of seed development of Brassica rapa (mustard plant)? If we pour acid rain on a plant then it won’t grow and there will be the same amount of seeds because the acid poisons the plant and kills it. Based off of the results I recieved after doing the experiment, my hypothesis rejects the data and is the complete opposite. I made this hypothesis based off of all the harsh effects that acid has on things, but in this case I was proved wrong. During this…

uniform, short flowering time (14 days) and grow well under in a small indoor space, with little soil, under artificial lights”(The Story of Fast Plants). Wisconsin fast plant are plants that grow at a very high speed rate. Their scientific name is Brassica rapa. Plants have enzymes, enzymes are special proteins that are essential for living organisms. Enzymes have preferred environments. “If an environment is too acidic (low pH) or alkaline (high pH) an enzyme won't function,…

from the oilseed brassicas. Since, the oilseed brassicas are more prone to the fungal attack and thereby, resulting in reduced productivity of the oilseed. Therefore, the present investigation focuses on the studying the features such as morphological, pathological and molecular variability of Alternaria brassicae. The characteristic features of the fungal pathogen Alternaria brassicae is deeply analyzed in this part of chapter and then breeding of fungal resistant oilseed brassicas could be…

Introduction Every seed and plant contain plant hormones; signal molecules produced inside of a plant in extremely low concentrations. Phytohormones, as plant hormones and growth hormones are sometimes referred to as, are chemicals that can regulate and alter plant growth and development. Hormones such as cytokinin have the ability to shape the development of plants from seed germination, to root and shoot growth, to the timing of flowering and growing the plant itself. There are many…
