Shehata %J Journal of Engineering and Applied Sciences %D 2012 %I Asian Research Publishing Network (ARPN) %X In the present work, morphological and ecological characteristics of three Egyptian Cyanophyceae genera; Oscillatoria (five species), Lyngbya (three species) and Anabaena (three species) were analyzed using numerical taxonomic system of multivariate statistical program. Data were analyzed by clustering method and similarity coefficients using NTSYSpc version 2.02i. Three different phenograms were produced for the studied genera and the relationships between the species were discussed. %K soil cyanophyceae %K Oscillatoria %K Lyngbya %K Anabaena %K numerical analysis %K cluster method %K species relationships %K Egypt. %U http://www.arpnjournals.com/jabs/research_papers/rp_2012/jabs_0412_389.pdf
