Summary
While tube elongation of growing pollen ofCamellia japonica was stopped by treatment with 50–100 ppm of myrmicacin, protoplasmic movement in the pollen tube still continued. However, higher concentration (200 ppm) of the inhibitor arrested the movement. The vesicles containing membrane substances disappeared at the tip of the tube of the growth-inhibited pollen. Removal of the inhibitor resulted in the reappearance of the vesicles at the tip region and tube elongation was restored.
