Figure 6From: Real-time measurement of phloem turgor pressure in Hevea brasiliensis with a modified cell pressure probeTwo typical real-time measurements of phloem turgor pressures subjected to tapping. Tree A is a normal tapping tree, whilst tree B was subjected to 2.5% ethrel stimulation at 54 hours before the tapping. The upward arrows indicate the time of tapping and the downward arrows indicate the stoppage of latex flow.Back to article page
