Using The Unispec To Test The Difference In Reflectance Of The Yellow Petals Of Encelia Californica, Encelia Farinosa, And Spartium Junceum, Mariam E. Fam, Valerie E. Espinoza
Using The Unispec To Test The Difference In Reflectance Of The Yellow Petals Of Encelia Californica, Encelia Farinosa, And Spartium Junceum, Mariam E. Fam, Valerie E. Espinoza
Featured Research
The reflectance spectrum of three yellow flowered species (Encelia californica, Encelia farinosa, and Spartium junceum), all grown on the coast of California, was tested to determine if reflectance among the yellow flowers was significantly different. It was hypothesized that there would be a significant difference in reflectance in the 400-700 nm wavebands for the three different species of flowers which all possess yellow petals. Using a Unispec Spectral Analysis System to obtain reflectance spectra for 12 yellow petals of three flowered species, a custom index was created in order to observe differences in the yellow color of the petals, which …
A Comparison Of Brittlebush (Encelia Farinosa) Productivity And Health During Drought And Post Rainfall, Gabi Diciolli, Karre Lawson, Anders Reimer
A Comparison Of Brittlebush (Encelia Farinosa) Productivity And Health During Drought And Post Rainfall, Gabi Diciolli, Karre Lawson, Anders Reimer
Featured Research
Encelia farinosa is well adapted for drought tolerance as its leaves transform color based on water availability. We were puzzled by a question that any desert botanist must consider. How does the photosynthetic efficiency of E. farinosa fluctuate as it transitions from a state of drought to a state of soil saturation within a 72 hour period? In this experiment we looked at the effects of irrigation on the health and quantum yield of the brittlebush by looking at photosynthetic rates using the portable photosynthesis system LI-COR 6400 when applied to two leaves on a given plant and water potential …
