Research Information

Research Question
DOES THE ENVIRONMENT (High or Low food concentration) HAVE ANY INFLUENCE ON THE NUMBER OF TRICHROMES PRESENT ON THE FIRST TRUE LEAVES OF WISCONSIN FASTPLANTS?

Research Predictions
The plants that have more nutrients, will have more trichromes than the plants that are not as nourished

Experimental Design
We set up a high fertilizer concentration (4 pellets/ plant) and a low fertilizer concentration (1 pellet / plant).
There were 6 seeds planted into the high fertilizer environment and 6 seeds planted into the low fertilizer environment.
Water, light, and temperature were kept constant throughout the experiment.
All available phenotypic data was collected as the plants were growing (plant height, stem color, leaf color, and trichrome numbers on the first true leaf)

Research Conclusions
In conclusion the reason for these results could be caused by experimental errors like, incorrectly counting the tricromes, the plant being sick and or having fertilizer burn. In the t-test the results show that there was no significance difference in the tricrome count between the 2 class periods. In the second data table it shows that 2 years ago there was a significance tricrome count compared to this year.

	October 31, 2011 \| 8:51 AM \| drummajor (Team Member) the second data table In the second data table it shows the comparison of the plants from this year and 2 years ago. It shows that 2 years ago that there was a significant difference in the tricrome counts, compared to this year how there was no significance difference.


	October 31, 2011 \| 8:42 AM \| drummajor (Team Member) data table results Thank you. In the 1st data table uploaded shows that there is no significance difference in our low and high fertilizer concentrate for the 2 class periods.


	October 29, 2011 \| 2:23 PM \| Jeremy Rentsch (Scientist/Mentor) Interesting results and I enjoy your pictures. I am surprised that your low fertilizer treatment might have fertilizer burn, but your high fertilizer treatment does not. The plant could be sick for another reason. It would take more space, but it's usually most effective to set up replicates of each experiment. That would allow you perform statistics between treatments and also help account for random plant damage, like you are seeing now.


	October 27, 2011 \| 8:58 AM \| drummajor (Team Member) Tricrome Count Our high fertilizer conentrate has 27 tricromes and our low fertilizer conentrate has 10 tricromes


	October 27, 2011 \| 8:50 AM \| drummajor (Team Member) Fertilizer Burn Our low fertilizer plant has fertilizerr burn is there any way to fix it?


	October 7, 2011 \| 4:12 PM \| Jeremy Rentsch (Scientist/Mentor) Good question! It is certainly possible to over fertilize plants. Do a little research on fertilizer burn. That might have been a problem. Good luck!


	October 7, 2011 \| 9:40 AM \| redneck (Team Member) Question Why does the Low Fretilizer Conentrate(12 pellets) have more plants than the High Concentrate(24 pellets)?


	October 5, 2011 \| 9:55 AM \| redneck (Team Member) Welcoming Hello! this is team 2 from Wichita North high school we are seniors and juniors. The people in our group are Brandon, Luis, Pedro and Jamie. We are very excited to be working with you.


	September 29, 2011 \| 10:47 AM \| Dr. Catrina Adams Welcome! I am happy to welcome you to this community of plant researchers. Your team has the opportunity to be mentored by a scientist to help you develop and perform your own research project. The mentor's role is to encourage and guide you through the scientific process of discovery. The more you share your ideas and research information online, the more your mentor can help. Your scientist mentor for this project will be Doctoral Candidate Jeremy Rentsch from University of Georgia. Please introduce yourself and post some possible research topic ideas to get a conversation rolling. These resources are available to help you get started: Thinking Like a Scientist / Working Like a Scientist Designing Experiments Guide to Using A Spreadsheet Best wishes as you start this scientific journey. We are all pleased to share this experience with you. Have fun! Sincerely, The PlantingScience team
