PD withdrawal rate under different relative humidities. (A) Comparison of the withdrawal rates of isolated PDs and PDs on ovules under laboratory conditions; (B) withdrawal rate under 50% and 100% relative humidity (red arrow, isolated PDs did not withdraw after 20 days under 100% relative humidity); (C) withdrawal rate under 50% and 100% relative humidity.
