Axillary Bud Strengths

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.

Two treatment groups were covered with a screen in order to reduce light intensity. Both groups were kept under a controlled light source for fourteen days and plant counts were taken at regular intervals.

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.

might affect the fitness of each variant. In other words which factors might increase plant growth, survival,

The purpose of the experiment is to study the hyphal tip growth, and to observe the effects of a drug on the tip growth and the

Specifically, the authors looked at the effect that the red to far red light ratio had on branching in Arabidopsis. The authors ultimately found that the effect that phytochromes had on branching varied significantly depending on the environment that the plant was in. Through the observations of the authors, this primary literature will be useful in helping me assess the effects that phytochromes have in the development of branches in

Hypothesis: The duckweed will show a small growth increase with very low levels of salinity and then will show a decline in growth rate as the levels of salinity increase.

What water level did you select for plant growth during your first attempt? Describe the observations of your plants at this water level. Based on your data, was the level you picked the best choice for optimum

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

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

We noted if any plants died, how dry the tray looked, and various other observations. Final measurements will be taken on April 12, 2016. Final measurements include: the length of the stem, stem length from the korm, weight of the korm, steam weight without the leaves, and stem weights with the leaves. To find the growth of each treatment, we will divide the final date by the initial data collected. Specifically, our group will divide elephant ear growth by Iris growth. So, we will compare the growths of the EI pots. If the proportional of elephant ear versus iris is bigge than 1, this means that the Elephant ear grew larger than Iris. We can then input the data into the respectable ANOVA tests and Post Hoc tests to further analyze our

The purpose of this lab was to focus on the gene encoding of six traits from the pure bred garden pea (Pisum sativum). The six traits observed were Seed color, Seed texture, Tendrils, Leaflets, Stipules, and Height. The purpose of each experiment was to analyze morphological traits and then Finding the statistical analysis by using the chi-squared test. The chi-squared test is when we collected the data of the garden pea and compared it to see if the variation in the data was due to chance or to a variable that was actually tested. This test helps us determine if our data is significant or non significant.

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

This data shows a strange outcome, in the hypothesis; it says that “If acid is introduced to the seed during germination, then the roots will not grow as long as the seeds that are given water”. This statement proves to be untrue, because the roots grew longer with stronger acid than weaker acid, and in some, cases, grew better with strong acid than it did in water. This may be true because of the acid growth theory. The acid growth theory states that auxins cause the elongation of stem cells by promoting wall loosening. It was determined that this wall loosening is caused by hydrogen ions. This idea and subsequent supporting data gave rise to the acid growth theory, which states that when exposed to auxins, susceptible cells excrete protons into the wall at an enhanced rate, which in turn decreases the pH in the wall. The lowered wall pH then activates the wall loosening process which is essentially doing the same thing as the auxin hormone.
