Inhibition of gamete formation by cycloheximide in pollen tubes of Impatients balsamina

Abstract
Cycloheximide (CH) inhibited the division of generative cell in pollen cultures of Impatiens balsamina in concentrations of 1–200 μg/ml without affecting pollen germination or pollen tube growth. This inhibition was reversible up to 3 h in hanging drop cultures and up to 6 h in test tube cultures by replacement of the medium with a CH-free one.
