The present study was carried out in the lab. of plant tissue culture at King Abdulaziz University to investigate morphological characterization of four Pandanus species of different genetic background. The used Pandanus species were Pandanus odoratissimus naturally grown in different regions of Saudi Arabia and Pandanus dubius, Pandanus tectorius var ‘Variegata’ and Pandanus tectorius var ‘Utilis’ collected from the agriculture market of Jeddah, Saudi Arabia. About 15 seedling of each species were organized in Randomized Complete Block (CRD) using 5 replicates. Morphological characterization was carried out using leaves of different ages of Pandanus species. The results showed that Pandanus tectorius var ‘Variegata’ revealed highest leaf breadth, leaf thickness and leaf contents of P (%). Pandanus odoratissimus illustrated highest Ch a and Ch b contents (mg/100g). Pandanus dubius recorded highest leaf length (cm). leaves of medium ages of Pandanus (leaves found in the meddle layers of plant crown) revealed highest values of leaf length (cm), leaf breadth (cm), leaf thickness (mm), leaf fresh and dry weight (g), and Ch a and Ch b (mg/100g). The new young leaves (found in the first internal layers of plant crown) revealed highest contents of N (%) and P (%). Length, breadth and thickness of the meddle leaves were successfully utilized for morphological identification of Pandanus odoratissimus, Pandanus dubius, Pandanus tectorius var ‘Variegata’ and Pandanus tectorius var ‘Utilis’.
