Abstract:
We studied the fitness and abortion levels in five species of genus Cestrum L. (Solanaceae) present in a cloud forest of Parque Nacional Henri Pittier, Venezuela. The seed set is variable and the abortion is higher at flowers-fruits and ovule levels, while the S/O ratio is low. We discuss the possible causes of abortion and seed set in these species.
