Selection of Least Leaf Density of Brassica rapa in an Artificial Selection Experiment Abstract: We investigated Brassica rapa leaf density trait by conducting an negative artificial selection experiment. In our experiment‚ we planted two population of 98 Brassica rapa: one for negative selection treatment‚ and another for control treatment. After the plants grew up‚ we measured the leaf density of both treatments. We then randomly selected 10 parents in control treatment‚ and also selected 10

Brassica rapa var rapa (Man Jing Turnip) is an important biennial‚ outcrossing‚ mesopolyploid herbaceous plant in the family Brassicaceae‚ native throughout Europe‚ Russia‚ Central Asia and the Near East (Prakash & Hinata 1980 ) with Europe proposed as one centre of origin.. In the alpine regions of the Qinghai-Tibetan Plateau it was widely used as a food source‚ when other crop production was limited approximately 2000 B.C. These highlands range in altitude between 3000-4000 m and are characterized

growth of Brassica rapa. The common name for Brassica rapa is field mustard and a type of plant is a cabbage. The plant was grown in solutions of pH 3 and 5.6 and the control was a solution of pH 7. This was done over 3 weeks and the plants were measured every day at the same time. The results of growth from day 4 to day 10 were recorded and they show that the plant grew the most in the pH of 5.6 at first but by the 10th day‚ the plant in the solution of pH 7 had grown the most and the plant in the

Borgognone Department of Biology‚ Fairfield University‚ Fairfield‚ Connecticut General Biology II Laboratory‚ Independent Plant Study of Brassica Rapa Introduction In the experiment we will be analyze the effects of UV-C radiation on Brassica Rapa. Brassica Rapa commonly known as field mustard because of its close relationship to mustard and cabbage.(1) this plant has proved to be a great plant for scientific research due to its fast and successful

BSC111L H002 2 November 2015 Introduction Brassica rapa vegetables perform a largely substantial role in not only the production but also the consumption of vegetables throughout the world. A few examples of Brassica rapa vegetables include Brussels sprouts‚ turnips‚ cabbage‚ broccoli‚ and cauliflower‚ and each of these are packed with minerals‚ vitamins‚ and fiber (Francisco‚ Soengas‚ and Velasco 2011). Because of the significance of these Brassica plants‚ knowing which environmental conditions are

cycle of the “Fast Plant” Brassica rapa. Another purpose of this experiment was to develop a better understanding of growth in plants. Meanwhile getting a closer look at their growth‚ students in the botany laboratory class looked at some genetic crosses and learned about the different traits passed on from one plant to another. Methods and materials The first lab students attended was August 26‚ 2009. In that lab‚ each one of them gathered the materials to plant the Fast Plants. The seeds were

One of the main steps in the scientific method is forming a hypothesis. Increasing fertilizer is expected to increase rate of growth and increase number of leaves.

Period 2. 03/05/17 Introduction: To have a successful germination‚ the plant seed needs a sufficient amount of water and oxygen present. Other conditions include room temperature‚ and the amount of light intake. Hydration of a seed‚ is an essential step for seed germination (Martínez-Andújar‚ 2014). Plants tend to germinate better in freshwater rather than salt

Fast Plants Lab Background Gregor Mendel is an Australian monk‚ who worked in a garden at a monastery. He experimented with pea plants‚ and soon became known as the father of genetics. The reason he studied pea plants was because they grow quickly‚ the traits can be easily observed‚ and the plant is easy to pollinate. Mendel’s method was to control the pollination of the pea plants and create offspring’s of the two plants that were pollinated together. Using self-pollination and cross pollination
