1

each group will grow Brassica rapa seedlings in a quad of -- cells

16 (4 units of 4 cells each)

2

3 treatments: --, salt stress, and plant competition

high vs low nutrients

3

monitor plants and complete two harvests to measure -- and growth related traits

biomass

4

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

5

a single treatment is made up of -- units of -- cells

2 units of 4 cells

6

In week 3, thin to the -- plant in each cell (except in the plant competition treatments)

largest

7

plants require nitrogen, --, and potassium

phosphorus

8

T/F: different plant species may require higher or lower concentrations and proportions of nutrients

true

9

some plants have adapted to grow in nutrient poor environments such as --, on rocks or as epiphytes

high elevation soils

10

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

11

plants more sensitive to salt-effects

glycophytes

12

plants that tolerate higher salt levels

halophytes

13

T/F: although halophytes can tolerate saline soils, high salt levels may still affect their growth and dev

true

14

many crop species are -- which present a major challenge to farmers in coastal regions and areas with poor drainage

glycophytes

15

differences in growth rate may result from evolutionary responses to environmental conditions, or -- in response to a changing environment or a combination

plastic changes

16

find at least -- papers in scientific journals

3

17

all plant rely on the same basic resources to grow and survive

water, light, nutrients

18

other factors like -- may affect how well a plant can access and utilize water, light, and nutrients

plant density

19

add 3 fertilizer pellets to each cell except

low nutrient (only 1 fertilizer pellet)

20

plant 3 seeds per cell except

high plant density (6) and low plant density (2)

21

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

22

no salt: spray plant with -- 1x per week every week after the first harvest until final harvest lab 8

dH2O

23

two harvests to measure biomass and growth related traits

lab 4 and 7
