Abstract |
: |
The science of classification is used to identify and name plants, know their chemical properties, and genetically classify plants. Species is the primary category in classification and it could be descried as a group of individuals that naturally reproduce among themselves and reproduce intuitively or do not reproduce with individuals of other types of one origin. Differences between individuals of the same species may appear as a result of environmental conditions. Morphology, anatomy, phytochemistry, palynology and molecular are different tools in taxonomy. All of them require doing lots of analysis and tests in laboratory. The aim of the current study was to test and use the remote sensing and Hyperspectral data as a taxonomy tool to elucidate the intraspecific relationship in the genus Prosopis julifora in relation to the environmental conditions. The Spectro-radiometer technology was used as a method in this research to measure the effect of different optical spectra on Prosopis juliflora leaves. The spectrophotometer helped identify these species in the study area. The Spectro-radiometer technology was applied to a sample of multiples of 10 trees in one sites, and was measured in the presence of strong sunlight, from 10:00 am to 12:00 pm during the different seasons of the year. The first collection was in Feb. 2019, the second in Sep. 2019, the third in Nov. 2019 and the fourth and last was in Feb. 2020. The results showed that there are differences between Prosopis juliflora taxa examined. When exposed to different spectrum wavelengths that show the spectral signature behavior of these types, samples 4 and 5 represented similar groups while samples 2, 8, and 10 represented another group in the different times examined. Therefore, it could be said that the hyperspectral radiometer technology is effective in indicating differences between taxa. Even though, there is a need for more research in this field. |
