How long does it take for Brassica rapa to grow?
The plants are relatively compact and need very little inputs or maintenance to complete the life cycle (seed to seed) in ~56-60 days.
How tall does Brassica rapa grow?
1 to 3
Plants grow 1 to 3 (or 4) ft tall from a sometimes fleshy, enlarged taproot, with a many-branched stem. The foliage is generally hairless and sometimes covered with a whitish film. Lower leaves can reach 12 inches long, have a large central lobe, and usually one to four pairs of smaller side lobes.
How long is the life cycle of Brassica rapa?
Fast Plants, rapid-cycling Brassica rapa, have a short 35-40 day life cycle from the day the seeds are planted to the day the seeds are harvested. The radicle (embryonic root) emerges. Seedlings emerge from the soil. Two cotyledons (seed leaves) appear and the hypocotyl (embryonic stem) extends upward.
How much water do Brassica rapa need?
4 mL per day
The amount of water given to Brassica rapa will not affect how fast it progresses through its life cycle. Our goal was to find the least amount of water needed for Brassica rapa to complete a full life cycle. Our research suggests that this amount is 4 mL per day per plant.
Why are Wisconsin plants so fast?
The Wisconsin Fast Plants are relatives of cabbage and broccoli that progress from seed to plant to flower in just 14 days, then on to seed by 40 days. Introduced by plant pathologist Paul Williams in 1987, the plants allow students to explore the effects of cross-breeding.
What is rapid cycling Brassica rapa?
Rapid cycling Brassica rapa (RCBr), more commonly known as Wisconsin Fast Plants, is a widely used organism in science education. They are used at both K-12 and college levels as a model system for topics including growth and development, ecology, physiology, reproduction, and genetics.
What is the benefit of Brassica rapa as a model organism?
rapa can be used as a relevant model organism for teaching human genetics because they share two important features with humans: 1) they do not self-pollinate, and 2) they are genetically diverse.
How fast do Wisconsin fast plants grow?
Characteristics of Fast Plants Fast plants reach a height of about 15 cm, flower after about 14 days and have a standard seed to seed growth cycle of about 35 to 40 days, with no seed dormancy period. Fast plants are very easy to grow in a standard potting mix under uninterrupted fluorescent lighting.
What are some types of Brassica plants?
Species Brassica balearica: Mallorca cabbage Brassica carinata: Abyssinian mustard or Abyssinian cabbage, used to produce biodiesel Brassica elongata: elongated mustard Brassica fruticulosa: Mediterranean cabbage Brassica hilarionis: St. Brassica juncea: Indian mustard, brown and leaf mustards, Sarepta mustard
What is the Brassica rapa life cycle’?
Brassica rapa of the rapid cycling group (RCBr) possess an average life cycle of approximately 35 to 40 days when grown under continuous cool white fluorescent light. They were developed from brassicas with a normal 6 to 12 month life cycle by continuous genetic selection.
What are plants in the brassica family?
What does Brassica rapa mean?
Brassica rapa. A plant species cultivated for the seed used as animal feed and as a source of canola cooking oil.
