The Pollen Morphological Characteristics Pollen Super Red Dragon Fruit (Hylocereus Costaricensis) with A Scanning Electron Microscopy as Biology Learning Source of Senior High School

Abstract

The study palinologi important to prove especially in plant taxonomy. Technological progress with the scanning electron microscopy (SEM) can support in the field of knowledge palinologi because of the world of more than a light microscope. The purpose of this research is described morphological structure pollen Hylocereus costaricensis (super red dragon fruit) use SEM, and use it as biology learning source of senior high school. This research is a descriptive qualitative study that describes the results of observations of pollen Hylocereus costaricensis based on relevant literature. The sample is pollen Hylocereus costaricensis. The object of study that observed is a unit of pollen, the form of pollen, size, aperture and ornamentation eksin. The result showed that Hylocereus costaricensis are categorized in the unit of a monad, the form of subsferodial, the size of magna, the aperture of tricolpate and the ornamentation of spinulose. This research result can be used as biology learning source of senior high school.
