Physiological responses of oil palm (Elaeis quineensis Jaq.) seedlings to sulphur dioxide fumigation.

A fumigation experiment was designed to determine the effects of varying concentrations and durations exposure to SO2 on one year old of oil palm seedlings. Plants were exposed to 0.005,0.1,0.1,0.5,1.0 and 3.0 ppm of SO2 for 1,2 and 3h in a controlled environment chamber. The control and fumigated p...
