Geomorphological landforms play an important role in the establishment of vegetation, especially in drylands. Earth fissures are known as one of the most interesting landforms in drylands. Polygonal hydro-geomorphologic patterns are formed by fissures connections in Yazd-Ardakan plain. This study aimed to compare the Haloxylon aphyllum physiological factors such as sugar, proline, nitrogen, phosphorus, sodium, potassium and Na+/K+ of aerial and underground part of Haloxylon aphyllum that grow in the mouth of fissures as treatment with the same age individuals out of fissures as controls. According to the results, nitrogen, potassium and Na+/K+ content of the trees were significantly different (α= 1%). Results indicated that fissure provide more nutrients for the established species. This study indicated that fissures landforms can be considered as good places for desert reclamation activities.
