Introduction:
There are many defining characteristics of the family Brassicaceae (Cruciferae). Some characteristics are lobed leaves, non-reproductive parts consist of four sepals, four petals in a cruciform arrangement. The stamens are tetradynamous meaning they have four long stamens and two short (Distinguishing characteristics of plant families). The floral structure of the family Brassicaceae is very different from other families because they’re fruits.
Brassicaceae (Cruciferae) are economically important because they provide food for animals and humans, such as broccoli, cabbage, kale, cauliflower, radish, and turnips. The Brassicaceae family is important medicinally as well. They contain factors that may prevent different types of cancers, the leaves are used for rheumatism and toothaches, the seeds are used for headache and tonic. Though, some mustard oils can cause skin irritation and ulcers from both consumption and external application (Manohar et. al 2012).
According to Brian 1959, the characteristic effects of gibberellin on shoot growth are increased inter-node extension, increased leaf-growth, and enhanced apical dormancy. Gibberellins, as growth hormones, speed up the rate of cellular metabolic pathways such as respiration and protein synthesis. Gibberellins are important in metabolizing lipids to glucose and then to sucrose through the gluconeogenesis process. Gibberellins are also known for their effect on membrane changes through the fast turnover of lipids (Plant Hormones-Gibberellins).
When gibberellins are applied to wild type plants there are other effects other than growth. According to a study conducted (Rood et. al 1988), the application of gibberellin directly to the shoot tip of the rosette r...

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
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
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
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
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
In ancient Egypt, the Egyptians would trade with the Mediterranean so the Egyptians would learn from their ideas and methods. The culture is all about eternity and the afterlife. It was believed that the pharaohs also ruled with gods which made the Egyptians where they would ensure the pharaohs afterlife with all the great things he had while alive. The Egyptians would bury the Pharaohs belongings with him and would even go to the extreme where they killed servants and family members to be buried
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
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
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
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
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
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
