indirect prediction of surface ozone concentration by plant growth responses in east asia using mini-open top chambers. | we developed small and mobile open top chambers (mini-otc) measuring 0.6 m (w) × 0.6 m (d) × 1.2 m (h) with an air duct of 0.6 m (w) × 0.23 m (d) × 1.2 m (h). the air duct can be filled with activated charcoal to blow charcoal filtered air (cf) into the chamber, as opposed to non-filtered ambient air (nf). ozone sensitive radish raphanus sativus cv. red chime and rosette pakchoi brassica campestris var. rosularis cv. atu171 were exposed to nf and cf in mini-otcs at different locations in east as ... | 2013 | 22752963 |
