Lab 2: FastPlant Set-up and Experimental Design Flashcards
(23 cards)
each group will grow Brassica rapa seedlings in a quad of – cells
16 (4 units of 4 cells each)
3 treatments: –, salt stress, and plant competition
high vs low nutrients
monitor plants and complete two harvests to measure – and growth related traits
biomass
break up quad to randomize the placement of the plants across the two light benches to help control for – that could affect growth
microclimate differences
a single treatment is made up of – units of – cells
2 units of 4 cells
In week 3, thin to the – plant in each cell (except in the plant competition treatments)
largest
plants require nitrogen, –, and potassium
phosphorus
T/F: different plant species may require higher or lower concentrations and proportions of nutrients
true
some plants have adapted to grow in nutrient poor environments such as –, on rocks or as epiphytes
high elevation soils
saline soils can be a challenge to “normal” plant growth because of the ionic effects of Na+ induce water deficits, –, and nutritional disorders
oxidative stress
plants more sensitive to salt-effects
glycophytes
plants that tolerate higher salt levels
halophytes
T/F: although halophytes can tolerate saline soils, high salt levels may still affect their growth and dev
true
many crop species are – which present a major challenge to farmers in coastal regions and areas with poor drainage
glycophytes
differences in growth rate may result from evolutionary responses to environmental conditions, or – in response to a changing environment or a combination
plastic changes
find at least – papers in scientific journals
3
all plant rely on the same basic resources to grow and survive
water, light, nutrients
other factors like – may affect how well a plant can access and utilize water, light, and nutrients
plant density
add 3 fertilizer pellets to each cell except
low nutrient (only 1 fertilizer pellet)
plant 3 seeds per cell except
high plant density (6) and low plant density (2)
high salt: spray plants with – or 35g/L NaCl in water 1x per week every week after the first harvest until final harvest Lab 8
ocean H2O
no salt: spray plant with – 1x per week every week after the first harvest until final harvest lab 8
dH2O
two harvests to measure biomass and growth related traits
