The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Past Methods (No longer in use)
- Growing clones
Two clones of white (Ladino) clover, originally isolated at North Carolina State University for their tolerance and sensitivity to ozone, were grown in pots of greenhouse soil under standard greenhouse cultural conditions. During the summer months multiple pots of each clone were placed outside at the Proctor Maple Research Center (PMRC) or used in ozone fumigation experiments at UVM.
Experimental exposures consisted of 3 daily 6 hr exposures of both clones to 100-150 ppb ozone; there were no control (non-ozone) treatments.
- Measurements of response
Measures of response (foliar chlorosis, necrosis and chlorophyll concentration and shoot and root biomass) were evaluated 10 days after treatments.
