Regression predicted that 1.5 g of carrot root tissue is lost for every g of chlorotic leaf dry weight caused by ozone injury.

e0“Container-grown plants of carrot ( Daucus carota L.) exposed intermittently to 0.19 or 0.25 ppm ozone throughout their growth increased in plant height and total number of leaves in spite of the development of chlorotic leaves”
e5“predicted that 1.5 g of root tissue is lost for every g of chlorotic leaf dry weight caused by ozone injury”

Other claims from this paper (5)
- Intervention effect Intermittent ozone exposure increased plant height and total leaf number of carrot despite chlorotic leaves.
- Intervention effect Ozone left carrot leaf dry weight unaffected.
- Intervention effect Ozone decreased carrot root dry matter by 32 to 46%.
- Intervention effect Ozone significantly declined the root weight/total dry weight ratio and root/shoot ratio of carrot.
- Association Root dry weight on chlorotic leaf dry weight regression explained 35% of carrot root loss.
