  1. Introduction to Fast Plants Georgia Davis Feb. 2006

  2. Development • Dr. Paul H. Williams at the University of Wisconsin-Madison developed fast plants. • Originally developed for research in disease resistance. • Extended the material for classroom use. Williams PH and C Hill. 1986. Rapid-cycling populations of Brassicas. Science 232: 1385-1389.

  3. More development • 6 month life cycle reduced to 5 weeks by 20 years of breeding. • More than 30 years of breeding to date. • Other improvements: • Uniform flowering time • Uniform size • Optimized growing conditions

  4. From: www.fastplants.org/intro.lifecycle.php

  5. More than 150 traits identified in the material. • Original population was Brassica rapa. • Also developed populations for six related species. • Seeds can be stored up to 10 years.

  6. Standard Purple Stem, Hairy Non-Purple Stem Yellow-Green Leaf Non-Purple Stem, Yellow-Green Leaf Rosette dwarf (Gibberellin deficient) Tall Plant (Gibberellin Overexpression) Petite Plant (Gibberellin deficient) Variegated Types of Fast Plants

  7. Fast Plants • Rapid-cycling Brassicas • Crucifers • Cabbage • Turnips • Broccoli • Cauliflower • Mustards • Canola

  8. Relationship among Brassicas B. nigra (Bbb) b = 8 B. juncea (ABaabb) ab = 18 B. carinata (Bcbbcc) bc = 17 Raphanobrassica (Rrrcc) rc = 18 B. napus (ACaacc) ac = 19 B. oleracea (Ccc) c = 9 R. sativus (Rrr) r = 9 B. rapa (Aaa) a = 10 From: Around the World with Brassicas.

  9. Growth Requirements • Continuous fluorescent light • Continous Water (Tray with water that each pot sets in) • Continous Fertilizer (Pellets) • Peat/Vermiculite Potting Mix

  10. Manuals That Are Available At the High School Level • Spiraling Through Life With Fast Plants • Bottle Biology • Use recyclable materials for growing Fast Plants. • Wisconsin Fast Plants Manual • Using Fast Plants and Bottle Biology in the Classroom

  11. Types of Laboratories • Germination • Growth and Development • Life Cycle • Physiology • Reproduction • Ecology, environment, biotic and abiotic factors • Variation, heredity, evolution • Energy and nutrient cycling

  12. Types of Laboratories • Germination • Growth and Development • Life Cycle • Physiology • Reproduction • Ecology, environment, biotic and abiotic factors • Variation, heredity, evolution • Energy and nutrient cycling
