Observation of reproductive organs of Sarraceniaceae with SEM LV model

Abstract

The High Vacuum (HV) model of Scanning Electron Microscope (SEM) is commonly used to observe specimens coated with metal or carbon. To simplify the procedure and reduce the cost, we used the Low Vacuum (LV) model of Joel SEM to directly observe anthers, pollen, and seeds of Sarracenia, Darlingtonia, and Heliamphora. For the first time, these reproductive organs are recorded with SEM. We also compared their morphological similarities to test their inter-general affinities.
