  • SummaryThe turgor pressure of growing pollen tubes of the lily (Lilium longiflorum Thunb.) has been recorded using a turgor pressure probe. Insertion of the probe's micropipette was routinely accomplished, providing recording periods of 20 to 30 min. Probe insertion did not affect tube growth. The stable turgor values ranged between 0.1 and 0.4 MPa, the mean value being 0.209 ± 0.064 MPa (n=106). A brief increase in turgor, generated by injection of oil through the pressure probe, caused the… CONTINUE READING
