Non-destructive root oxygen use measurement III : cucumber propagation in rockwool in a climate chamber, July-August 2001

Cucumbers were propagated in rockwool cubes in a climate cell for four weeks. The complete root system of each cucumber was enclosed in an airtight box. Each box was connected to an air bag, which acted as an air reservoir. A peristaltic pump ensured air circulation in the system. The goal of this experiment was to measure the critical oxygen sypply rate for normal production. Additional goals were to characterise plant and root growth affected bij low oxygen availabilit
