Effect of Temperature on Flowering of Phalaenopsis Orchids Essay example

Throughout this experiment, we are researching the effect on the growth and survival of Wisconsin Fast Plants using fertilizer pellets to help with the growth of the plants. Wisconsin Fast Plants is a plant member of the crucifer family which is related to other plants (vegetables) such as cabbage, broccoli, turnips, etc. This plants are small and can grow very easily because they go through their cell cycle around 40 days. Wisconsin Fast Plants Fertilizers are different materials used that can provide plants with the nutrients it need to grow. (1) These plants are a good model system to study because they grew very quickly and didn’t need a lot of resources to grow making them the perfect plant to use for studies. (4) By using the fertilizers,

Identify features of flowers of native species of angiosperms that may be adaptations for wind, insect, bird and mammal pollination.

Clausen asks, “Can you imagine a garden without pansies”? This shows that the author has a strong love for pansies. The author provides a single paged photo layout of the natural beauty colors pansies are and their natural beauty. Clausen also provides the reader with bold letters to grab the reader’s attention. The bold letters consist of where to plant pansies, the propagation, and the culture of pansies. In addition, the author provides a graph of common names, botanical name, family, hardiness, conditions, blooming time, height and the best features the pansy has to offer. Clausen offers the information for the audience to be aware of the beauty pansies

Wingstem (Verbesina alternifolia) are an unbranched perennial plant that are primarily located in middle and eastern areas of North America. Wingstem grow in habitats that receive large amounts of sun and areas that are shaded. Wingstem thrive in areas with moist conditions, and receive periodic rainfall. Based on our knowledge of the chemical processes in plants, the Wingstem located in the sunlit areas will have greater reproduction, resulting in increased flowering rather than those in shaded locations. To test our hypothesis, we collected Wingstem in various habitats (sun and shaded). We then calculated the number of flowers, followed by weighing the total vegetation. The results demonstrate a significant difference between the number

The room temperature water rose 7.62 centimeters total over the 3 hour time period. The hot water rose 17.78 centimeters total, over the 3 hours. The water in the stalks without leaves did not rise, and was therefore unsuccessful, while the water in the stalks WITH leaves rose several more centimeters over a shorter time span, showing that respiration is linked in to the

Each plant received equal care and was placed in the same conditions. Soil used for planting was Miracal Grow planting soil. The soil also consisted of peat moss, composted inner bark of hardwoods, and micro nutrients. The pH of the soil was adjusted to 6.5. The plants were kept in greenhouse conditions at Anoka Ramsey Community College. They received equal amount of sun that was provided on a given spring Minnesotan day. Temperatures ranged from 10-27°C. Plants were watered as needed, at least two to three times per week.

In the control it averaged to be better than the experimental group. On November 2nd control 1, 2 and 3 showed a lot of growth ranging from 9.5- 12cm and sadly control 4 dead, throughout this project we could have changed something different to make all the plants grow the same way. However, on the last week Plant # 2 and #3 grew very large and made much more progress. Discussion/Conclusion

In Lab Girl, Hope Jahren describes flowers as being “a platform of petals surrounding the ‘male’ and ‘female’ parts” (202). Indeed, flowers play a fundamental role in plant reproduction and pollination. As an abundantly diverse species, they can be found in various habitats ranging from the Mojave Desert to the Everglades. Overall, a single flower, as beautiful and common as it may be, has the ability to lure insects, produce seeds, and ultimately facilitate new plant life.

ABSTRACT — In the present investigation, it was revealed that treatment with paclobutrazol (PBZ) @ 2.5, 5.0, 10 and 20 µg mL–1 resulted in shoot length and shoot dry weight to decrease significantly under normal condition, but increased significantly in salinity (4 dSm-1 and 8 dSm-1) with respect to control. Treatment with PBZ resulted in significant increase in root length and root dry weight as compared to control under both normal (PBZ) and saline conditions. Total chlorophyll was recorded to increase significantly at vegetative and flowering stages as compared to control. Hydrogen peroxide decreased significantly at vegetative and flowering stages. Treatment with PBZ resulted in significant increase in protein and total sugar content at

Analysis of Results Throughout this experiment the Controlled group height is always ahead of the Experimental Group. Eventually the Controlled Group is more than triple the size of the Experimental Group. On day 35 the average plant height for the Experimental Group was 3.1667 centimeters and the Controlled Group with a 18.25 centimeters. In the Experimental Group, Cell 1 had a height of 3.5 centimeters, Cell 2 never grew, Cell 3 had a height of 7.0, and Cell 4 had a height of 8.0 centimeters.

The flowering of plants is a tightly controlled process and flowering at the wrong time could cause detrimental problems for a plant, especially if it were to flower too early in the season. There are both environment and genetic factors that can influence flowering in Arabidopsis thaliana. In the winter-annual A. thaliana, environmental factors affect the gene expression of Flowering Locus C (FLC) (Michaels, et al., 2006). Environmental factors include the quality and quantity of light and vernalization, which is the promotion of flowering due to cold temperatures (Balasubramanian et al., 2006). Genetic factors include FRIGIDA (FRI), flowering

Ts’ai Yen, an ancient Chinese poetess who is captured by barbarians and gives birth to two children by a chieftain during her twelve years in exile. The music of Barbarians makes Ts’ai feel nostalgic for her lost family. One of her songs passed down is Eighteen Stanzas for a Barbarian Reed Pipe. Kingston revises the legend that better represents the similar experience of Brave Orchid and Kinston. Brave Orchid comes to America with a different culture backfround. Like the exiled poetess, Brave Orchid tells stories about China. Her daughter cannot fully understand her mother’s Chinese dialect and look the words up in the dictionary to figure out the meanings of curses that frighten her. Kingston, as an American-born child, speak another language.

Deceit in orchids have proved advantageous in floral and species diversification. The article,”Orchid diversity; an evolutionary consequence of deception?” was written by Salvatore Cozzollino and Alex Widmer. In this article they discuss two types of deceptions in orchids: food deception and sexual deception. These methods of deception, which are used for pollination, have proved successful where there are pollinator limitations. However, where there are successes there are also consequences. Some factors that orchid deception effects are: mating systems, the evolution of reproductive isolation, and the evolution of speciation. To understand these consequences is to better understand how these deceptive orchids have become successful.

The first of the two essays, Michael Pollan’s “Love and lies”, first published in National Geographic Magazine, explains the pollination process of orchids. Pollan’s paper describes the intricate process by which orchids reproduce, giving the reader an in depth knowledge
