Fusanolide, Pollen, Growth Regulator
Fusanolides A (1) and B (2) were isolated from cultures of the fungusFusarium sp. as pollen growth regulators and their structures were established by spectroscopic evidence.1 completely inhibited pine pollen germination and tea pollen tube growth at a concentration of 300 mg/l, but2showed no inhibitory effect on them at the same concentration.
