NOTES: [Brassica Plants growth conditions]

Ideal Growing Conditions	Probable Consequenses of Variying the Condition
40 watt cool white flourescent light	Other types of lights are too hot and can scorch the leaves.
Continous supply of water	Too little water leads to wilting and death of the plants.
Temperature between 70 & 80 degrees	If the temperature is between 60 & 70 degrees F, the growth cycle slows by several days. When the temperature is below 60 degrees F, the seeds fail to germinate.
24 hours of continuous light	When the plants have any less than continuous light, the life cycle sows down and the plants are skinnier and produce less flowers and seeds.
3 fertilizer pellets per cell	Underfertilization produces stunted plants, pale leaf color, delayed flowering and fewer seeds. Overfertilization results in increased flower, pod, and seed production, dark leaf color, delayed flowering, and stress due to the high levels of salts (fertilizer) in the soil.
1 plant per cell	The competition for water, light, air, and nutrients results in weakeer plants and yields fewer seeds.
Cross pollination	Unless flowers (blossoms) are cross-pollinated no viable seeds will be produced.

THE TOP TEN Brassic Plant Comments! (soon)...
1	Sydney L: "I had so much fun."
2	Sydney G: "I had so much fun getting the seeds to stick in the dirt."
3	Joe: "How are we going to get the dead bees?"
4	Miranda: "I look forward to watching our test plants grow."
5	Pearl: "I liked getting messy to plant the seeds."
6	Casey: "What happens if the plant doesn't grow?"
7	Donquis: "It's interesting to see how small the seeds are."
8	Sheliagh: "It's like we have our own mini-greenhouse at school."
9	James: "I can't wait to see what the fertilizer does to the test plants."
10	Mr. P: "Our class did a great job setting up reliable tests."

Experimenting with Brassica Plants!

[aka Wisconsin Fast Plants]…

The purpose of this study is to allow students an opportunity to learn about constructing a fair, controlled, and accurate scientific test.

The objectives of the experience will give the research (student) a chance to:

Ø Develop a good plan and follow through with it…

Ø Select a topic that is interesting and worth doing…

Ø Gather information that’s pertinent to the topic by reading, researching, and talking to experts…

Ø Observe results carefully over a period of time…

Ø Keep records accurately, honestly, and regularly…

Ø Measure and quantify…

Ø Make a conclusion(s) after gathering results…

Ø Communicate results…

The Wisconsin Fast plant is a genetically altered plant that was developed by Dr. Paul Williams at the University of Wisconsin. The plant pathologist through his study of Brassica Plants found that about 10% of the plants from each cycle grew faster. After years of selective breading a “new” special Brassica plant was developed. The “Wisconsin Fast Plant” (named for the University) emerged as a very good plant on which to perform scientific tests.

The qualities that make Wisconsin Fast Plants so desirable for testing are:

Ø The plants are compact and hardy…

Ø The plants thrive in a crowd…

Ø The plants produce abundant pollen thus producing lots of seeds…

Ø The plant use continuous 24 hour a day fluorescent light…

Ø The plants grow at a constant room temperature…

Ø The plants do not require a dormancy period before the seeds can germinate…

Ø The entire life span (from seed to seed) is only 36 days…

The variables that can be tested from the control plant are:

Ø Lighting

Ø Pollination

Ø Temperature

Ø Spacing

Ø Fertilization

Ø Watering
