| Summary: | Eldar pine introduction toIrandates back to many centuries ago. It has been severely changed in morphology in Khaf region and two different forms emerged. This study aims at using anatomical traits to differentiate Conical and Ball-shaped pines which are two new mutant forms of Eldar pine. The results of anatomical comparison showed that Conical-shaped pine is distinguished from two other pines in some valuable taxonomical traits, such as cross sectional form of needle, number of stomata on ventral face per unit area, number and position of resin ducts. Also the difference in characteristics like cuticle thickness, stomatal interval space in row, number of stomata per needle unit area, needle perimeter and length imply increasing the adaptation potential to aridity in Conical-shaped pine spec. nova in comparison with Eldar and Ball-shaped pines. |
