The transpiration stream is the uninterrupted passage of water from the soil to the air in plants. ... The next stage in the transpiration stream is water passing to the xylem vessels. The water either goes through the cortex cells (between the root cells and the xylem vessels) or it bypasses them – going through their...

Some radioactive material was transported upwards in the transpiration stream but the labelled compounds were not representative of the labelled compounds either in the wood or in the vacuum-extracted sap.

The method is entirely destructive but it should produce transpiration-stream fluid with only limited contamination from live cells. There was no difference between the levels of ammonium in this sap and that in excreta from insects feeding on the same plants immediately before excision (data not shown).
