Abnormal Shoot and Leaf Formation in Some Native Pine Species

18478

In many tree species, when abnormal shoot formation after fire, insect attack and grazing is being observed, this formation is not common in pine species and not well-known. This study was performed to investigate the formation and types of these abnormal shoots in Turkish red pine (Pinus brutia Ten.), Stone pine (Pinus pinea L.), Anatolian black pine (Pinus nigra Arn.) and Aleppo pine (Pinus halepensis Mill.). As results three types of abnormal shoot formations were illustrated. These are (1) Clustered short shoot formation in Anatolian black pine after grazing, (2) Rejuvenated shoot in Stone pine after forest fires, in Anatolian Black pine after grazing and in Aleppo pine after insect attack, and (3) Short shoot formation with three (-four) needle in Turkish red pine after grazing.
