Unflooded and flooded 12-wk-old seedlings were maintained for 8 wk in a growth chamber, then exposed to 0, 0.5, 1 or 1.5 micro lSO2/litre for 48 h and grown in the greenhouse for a further 6 wk. Flooding with stagnant water decreased the rate of height growth, needle initiation and expansion and dry wt. increment of leaves and roots but not stems. Flooding of unfumigated seedlings for an additional 6 wk also significantly reduced dry wt. increment of stems.
