The Economics of Human Exploration and Migration Somewhere between insatiable curiosity and voracious appetite for the accumulation of wealth lies the motivation for human travel. These two goalposts through which every explorer, merchant and conquistador to roam this planet sailed do not paint the idealized portrait of natural human character, but they nonetheless do accurately depict the aims of those ambitious enough to change the world and therefore merit a place in the halls of history
Evaluation of Fungicide Control of Sclerotinia Stem Rot on Canola (SSR) Yin Chen Description of disease affecting crop Sclerotinia stem rot (SSR) is caused by fungus named sclerotinia sclerotiorum (Lib.) de Bary. It is a common disease in oilseed rape (Brassica napus) field. In Sweden, S. sclerotiorum can cause 60% yield reduction in infected fields (Nordin, 1992). SSR is a major disease of canola in North Dakota. The incidence ranged from 7-19% in North Dakota from 1991 to 1993. ( Lamey, 1995). It occurs
authority(Heywood, 1978; Keil & Walters, 1988). The classification scheme for broccoli and indeed all of the other brassicas is clear and straightforward until one reaches the species level. At that point the addition of numerous subspecies, varieties, and cultivars results in a rather complex and confusing arrangement of-the taxa in question. For example, the scientific name for broccoli, Brassica oleracea (L.), is also shared by cabbage, Chinese cabbage, cauliflower, collards, brussels sprouts, kale, kohlrabi
The Effects of CO2 on Brassica rapa Growth Introduction Brassica rapa is a mustard plant that can be found throughout North America, and is common in areas undergoing extreme change, such as changes in climate. There is an important relationship between the ecological and genetic factors that influence the growth of Brassica rapa (Mitchell-Olds 1996). So, the environmental elements, as well as the genetic information, are essential to the growth rate and survival of Brassica rapa. This plant is capable
The plants of the genus Brassica include species very important for research and agricultural purposes including vital vegetable and oilseed crops (Augustine 2013). Research for these plants typically aim to increase their nutritional value and develop traits such as herbicide tolerance, sterility, and disease and pest resistance (Gupta 2012). One plant that can be used for research is Brassica rapa, in the form of Wisconsin Fast Plants, which are a rapid cycling variety that can be used for genetics
Mustard (Brassica) is a rotational cover or winter annual crop i.e., mostly used in vegetable and as well as production of raw crop. Mustard crop mostly have the potential to prevent suppress weeds, erosion, alleviate soil compaction, soil-borne pests and scavenge nutrients (Clark, 2007). Mustard crop has fastest fall growth, high production of biomass, and nutrient scavenging capability following for high insert of cash crops. Field mustard that can be grown as a cover crop alone or in a mix with
DISCUSSION The purpose of our experiment was to test whether or not the Wisconsin Fast Plants, or Brassica rapa, followed the Mendelian genetics and its law of inheritance. First, after we crossed the heterozygous F1 generation, we created an F2 generation which we used to analyze. After analyzing our results, we conducted a chi-square test for for both the F1 and F2 generations to test their “goodness of fit”. For the F1 generation we calculated an x2 value of 6.97, which was greater than the
We used Brassica rapa, a fast plant the rapidly reproduces, in an experiment that we performed a monohybrid cross and a dihybrid cross. We hypothesized that in the monohybrid cross, the F2 generation of Brassica rapa will follow Mendelian inheritance patterns and show a phenotypic ratio of 3 anthocyanin positive to 1 anthocyanin negative. If the F2 generation follows Mendelian inheritance patterns, then out of 1105 plants, 828.75 will be anthocyanin positive and 276.25 will be anthocyanin negative
Health Benefits of Turnip Turnip, scientifically known as Brassica rapa. It is a cruciferous root vegetable from the cruciferae family like collards, brussels, kale, cabbage, broccoli, sprout etc. Turnip is used in various diet. The baby turnips are the young ones that are harvested early. They are very sweet but delicate. Turnips can be used in making stew and soup, can be diced or pickled. The baby turnips can be used in making salad and are usually consumed raw.The leaves of the turnip are called
The Effect of Gibberellic Acid on Wild Type and Rosette Brassica rapa Plants Intro This experiment was performed to test two hypotheses concerning the plant hormone gibberellic acid and a mutant rosette shaped phenotype of the plant Brassica rapa. This experiment was done in order to test the effects o gibberellic acid on plants and its effect on rosette shaped complexes. The two hypotheses in this experiment are as follows: Hypothesis number one states that Gibberellic acid allows for stem elongation
Fertilizer is the most important component that the plant uses in its growth and development. A natural fertility of the soil takes a hundred years before it produces. Some decayed plants and animals are sources of organic fertilizer. By definition, organic fertilizers are derived from animal or vegetable matter, (e.g. compost manure). In contrast, the majority of fertilizer is extracted from minerals (e.g. phosphate rock) or produced industrially (e.g. ammonia). Naturally occurring organic matter/organic
Brassica oleraceae var. Italica becomes favorable due to the health-promoting compound which benefits to the consumer. Despite various benefit from broccoli consumption, this plant is sensitive to heat where nutrient easily loss. World Healthiest Foods, WHFoods recommended quick steaming method with only 4 minutes total steaming time in order to enjoy broccoli without a significant nutrient loss since broccoli is clearly sensitive to total steaming time.

colonizing and invading disturbed areas in the Inland Empire, San Bernardino Mountains, San Gabriel Mountains, Mojave Desert and Colorado Desert. The two main mustard species that are invading Southern California are Black Mustard (Brassica nigra) and Sahara Mustard (Brassica tournefortii). Black Mustard is most commonly found in the Inland Empire and surrounding mountains, while Sahara Mustard is found at the lower elevations in the Colorado Desert and San Diego County. The mustard plants grow extremely
Evolution is the heart of life. Without it, life could not be sustainable. When the environment changes and the species within the environment fails to adapt or change, then all living organisms would perish over time. Charles Darwin, a biologist and naturalist, is known worldwide for his contributions to science for the extensive research and experiments conducted to help support the theory of evolution and how it worked. One basic mechanism that can be used to understand evolution is natural selection
internode elongation because it prompts cell division and expansion in any light condition. Therefore, plants treated with gibberellic acid should grow taller than those treated without it (Gupta and Chakrabarty, 2013). Wisconsin Fast Plants, or Brassica rapa, are model organisms which have been bred for over thirty years. They are closely related to broccoli, cabbage, and turnips. This plant has a life
P1 (Semi Complete; Spell check)Growth is defined as a positive change over a period of time, it is increasing. Growth is defined in terms of size, weight, height it is an irreversible change. The definition does not just apply to heterotrophs it also applies to autotrophs. Heterotrophs gain the energy to grow through ingestion of food and Autotrophs use sunlight. There are two different types of growth in living organism. Determinate growth animals have it growth stops certain point. Indeterminate
vegetable from the brassica family. It is hardy, cooler seasoned plant that grows best in the spring, autumn and winter months (March, April, May, June, July) as it can tolerate frosty weather conditions. Kale produces erect stems with large leaves that are rich in minerals as well as the vitamins A and C. Kale is popular in salads and other healthy food mixes because of its rich content. Although kale is a healthy product, it is not a popular plant to grow unlike other brassicas such as broccoli and
I got involved with the Brueggeman fellowship because I wanted to have an opportunity to investigate on ending child marriage, a subject that has impacted many young girls and women all over the world. Being accepted to the Brueggeman fellowship program is very competitive, so much so that during my year (2015-2016), there were only six students accepted into the program. Therefore, getting involved in the Brueggeman fellowship was a way for me to challenge myself and prove that a young girl from
Introduction Many scientists in the past, such as Aristotle and Plato, believed that there were no changes in populations; however, other scientists, such as Darwin and Wallace, arose and argued that species inherit heritable traits from common ancestors and environmental forces drives out certain heritable traits that makes the species better suited to survive or be more “fit” for that environment. Therefore, species do change over a period of time and they were able to support their theory by
over the span of twenty-eight days. The objective is to observe how plants grow and use their resources throughout the span of their life. In our lab we observed the Brassica rapa, a herbaceous plant in the mustard family which has a short cycle which makes it a perfect plant to observe in this experiment. Like other plants the Brassica rapa must use the resources in the environment to create energy to complete itʻs life cycle and reproduce. By observing the plant it is easy to see in what organ or
