In order to compare adaptability and growth of Pinus elliottii and P. radiata, the trial was conducted in 1995 at Chamestan-Noor Forest and Rangeland Experimental station (Caspian Sea of Iran). The seedlings oftwo species were planted in separate groups. Each stand area was 7500m2. In addition, determination of survival and measurements of quantity accomplished (for five years). After 10 years, parameters such as survival, quantity and quality are determined. Finally, data with T-test method in SPSS are analyzed. Species comparisons showed that P. elliottii survival (75%) is more than P. radiata survival (57%) in the studied area. The mean diameter at breast height (D.B.H) of Slash pine and Monterey pine were 15/4 and 15.5 centimeters, respectively. Also mean height of Slash pine and Monterey pine were 11.1 and 9.5 meters, respectively. Analysis of mean height and diameter demonstrated that there were no significant difference for diameter growth between P. elliottii and P. radiata. However, there was significant difference for height growth between two species. Furthermore, volume per ha for P. elliottii 190 sylve and for P. radiata 91 sylve were determined. Comparison of two pines revealed that Slash pine (P. elliottii) grows faster and is more resistant than Monterey pine (P. radiata) in theChamestan region. Thus, Slash pine for plantation with aim of wood production and using of fast growing species is proposed.
