Study of the vitality and growth of three woody species in flood spreading areas

The utilization of flood and its spreading on flat plains is a reclamation approach for natural resources in most countries such as Iran. But existance of information about moisture condition in the different parts of spreading area and its impact on tree species is necessary. Therfore، this project was performed in Qarecharian spreading station (Zanjan province) during five years (2005-2009). Four seedlings from each tree species of Elaeagnus angustifolia، Amygdalus communis and Robinia pseudoacacia were planted at four locations considering moisture condition at the three spreading canals first، third and fifth in three replications for each. The vitality of each seedlings were noted after flooding and drought periods. The height and diameteric growth were also noted. The results showed، the third canal with the vitality of 63، third location with 72، and E. angustifolia with 91 seedlings were the best.
