  13. Impact of Ambient Ozone on Plant Productivity on LI: Reduction in Clover Biomass Estimated Based on Comparing Sensitive and Tolerant Clones

  14. Clover System for Assessing Ozone Impact Ozone-sensitive and ozone-tolerant clones. 10 plants of each grown outdoors in pots. Foliage removed, dried, and weighed every 28 days.

  15. Clover Project Activity Dates

  16. Reduction in Biomass Produced by Sensitive Clover Clone
