Germination

each treatment group. Using sterile technique with a pasteur pipette, 1 seed per agar plate grid-line was inoculated for a total of 7 seeds per treatment. The agar plates were sealed, labeled, and incubated at room temperature for 2 weeks. Then, germination frequency and the quality of seedling development was determined in both groups. To control for possible growth disturbances, the root length (mm) was assessed in the four roots closest to the left side of each agar plate using a standard…

My hypothesis is that the presence of broccoli will have a positive effect on germination of plant seeds. In my results, I saw that the hypothesis was in my favor because the stems of experimental groups were much longer then the stems of control group. Other works that have been done by scientist which relate to my experiment include Alleleopathy. Alleleopathy is “any direct or indirect harmful or beneficial effect of one plant… on another through prediction of chemical compounds that escape…

to Auxin, cytokinins also help with modifying apical dominance, but instead of promoting main stem growth it promotes lateral bud growth. Since cytokinins are such important growth hormones, the also play a part in beginning and continuing seed germination. Cytokinins also delay leaf senescence, the final stage of leaf development. Leaf senescence is when the leaves turn a different color, and transport all of their essential molecules back into the plant in preparation to fall. Cytokinins slow…

“the fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant.” (Dictionary.com) Seeds go through a process, called germination, to grow. The seed first has its roots break out and grab hold of the soil. After the roots have a hold of the soil a small plant will sprout from the ground. All plants go through the germination process. (How do Seeds Sprout?) The hypothesis is: If the weight of a seed affects the rate the plant grows, then a heavier seed will grow…

Effect of Water Availability on Germination of Acacia rubida and Swainsona formosa Seeds Question The aim of this experiment is to investigate whether water availability prior germination affects Acacia rubida and Swainsona formosa seed germination. We will control the water availability by pre-soaking time. Hypotheses Null hypotheses • Seed germination speed will not differ between long and short soaking time. • Change in soaking time will have same effect on A. rubida and S. formosa seeds.…

Number of accumulated germinations of poppy for each concentration of Gibberellic acid (group data) Graph 3. Number of accumulated germinations of radish for each concentration of Gibberellic acid (class data) Notice that the trend are similar for all . Graph 4. Number of accumulated germinations of poppy for each concentration of Gibberellic acid (class data) Discussion Regarding to graph 1 for radish…

Phytohormones, as plant hormones and growth hormones are sometimes referred to as, are chemicals that can regulate and alter plant growth and development. Hormones such as cytokinin have the ability to shape the development of plants from seed germination, to root and shoot growth, to the timing of flowering and growing the plant itself. There are many different Phytohormones that work together in a plant, cytokinin is one of them. Although the five are usually working together, they can also…

any effect on crop seed germination: germination time and number of germinated seeds. We did this by watering our seeds different concentrations of hydrogen peroxide. My partner and I tested on three different types of seeds; corn, bean, and pea. I hypothesized that the higher the concentration of hydrogen peroxide added, the higher percentage of seeds will grow in that solution. I also believed that higher concentrations of hydrogen peroxide would quicken seed germination among seed types. My…

In the beginning, the tiny seed was planted in the rich, dark soil of my mind. My mother taught me how to be a nurturing and caring mother by her example. She showed me that I was important by always being present in my life. She worked sometimes, but she never let her work become the priority and most of my life I felt that she was a stay at home mom, even though she worked part-time at the library and taught art classes. She taught me about Jesus, the importance of having a relationship with…

Finally, in order to find a response to the research question, the concentration of the solution that yields the highest average germination rate can be determined through graphical interpolation. Sample Calculation 1: Calculations performed in order to find the mean germination rate of the seeds for each concentration of gibberellic acid. In this experiment, the germination rate is the average time taken for the seeds to germinate, from the time of sowing. This calculation needs to be…
