Investigating And Potential Growth Of The Hormones Auxin And Gibberellin

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

The evidence that supports my research question provides some basis as well as stability for my conclusions. Attempting to engage in active research for the first time, and equipped with a question that has been explored to different degrees by reputable educators, it is easy for one to be daunted by the challenge. Yet one can take heart from the wealth of information available, and be encouraged to engage in

At the start of this experiment we were required to obtain a set of four Wisconsin Fast Plants, which are genetically, known as Brassica rapa. These plants have been, “originally selected under continuous fluorescent light to grow and reproduce quickly for research purposes, these petite, fast-growing plants have been used for teaching biology concepts” (Wisconsin Fast Plants). These four pots that contain our plants will be under our watch for the next 16 weeks where we will show our results at the end of the semester.

The tobacco plant like many plants contain a cell callus. A cell callus contains somatic undifferentiated cells and can be used to differentiate into specialized tissues of the tobacco plant, or any plant used, by being induced with the addition of different types of hormones, such as cytokinin and auxin. Cytokinin and auxin are mostly used in plant tissue culture simultaneously to provoke the formation of a plantlet or callus. There is a common use of Kinetin in plant tissue culture since when added it will promote cell division to initiate shoot tissues from calluses of the plant. Kinetin is a type of cytokinin hormone. In regards to auxin related hormones, Indole-3-acetic acid (IAA) is also commonly used since it promotes the initiation of roots for the root tissue of the plant. In this

The research done helped me understand how people can come together to understand a theory and to replicate those theories with experimentation and

If the terminal bud is removes, lateral axillary buds grow and produces new branches and the plants become bushier

Plants produce a wide variety of hormones. The nine main plant hormones are: Auxins, Gibberellins, Abscisic acid, Cytokinins, Ethylene, Brassinosteroids, Salicylic acid, Jasmonic acid and Strigolactone. Abscisic acid (ABA) was the one of the main focuses of this journal article. ABA is involved in the regulation of many aspects of plant growth and development including, embryo maturation, leaf senescence, stomatal aperture and adaptation to environmental stresses. Although it inhibits germination.

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects.

Records show that the practice of grafting is an ancient one, dating back well before the time of Christ It was once believed that any plant could be grafted on any other. This probably arose from observations made in tropical areas where seeds sometimes lodged in the cleft of a tree where seeds germinated and grew in the organic matter that had accumulated there. However, today, we know that only very closely related plants are capable of being grafted. Many forms of grafting are practiced, and the technique known as budding is widely used in the production of fruit trees, roses, and ornamental trees and shrubs. Without the practice of grafting many of the popular varieties we know today, such as the Delicious Apple or the Peace Rose, could not have been maintained. Wrong was the man who wrote in 1889: We doubt if there is a greater nuisance in the whole practice of gardening than the art of grafting. It is very clever, it is very interesting, but it will be no great loss if it is abolished altogether. While the technique of budding generally works best during June, July and August, many other forms of grafting are done just before plants begin new growth and are still dormant. Three terms are important in any discussion of grafting: stock, scion, and cambium. The stock is the rooted lower portion of a plant on which the graft is to be made. The scion is the shoot, bud or piece of twig to be fastened on the stock. Most important of all is the cambium, a thin layer of pale

height, stem diameter, leaf number, yield, pollen amount, pollen viability, pollen germination and parthenocarpic fruiting of genotypes were determined. GA3 levels were investigated in the samples collected from five different stages, ranging from the small bud to the small fruit. The responses of the genotypes were found significantly different for vegetative growth, pollen viability and fertility under low temperature conditions. The results showed that there was no relationship on vegetative and generative parameters and GA3 levels between parthenocarpic and non parthenocarpic eggplant genotypes (Boyaci et al., 2009a,b; Boyaci et al., 2011a). It was understood in this study that the parthenocarpy feature in eggplant is strongly influenced
