Investigation of leaf morphological characteristics of Quercus infectoria Oliv. (Aleppo Oak) in Kurdestan forests

In this study, leaf morphological attributes of Q. infectoria Oliv. (Aleppo oak) in Kurdestan forests were investigated due to obvious differences in leaf forms (Heterophylly) aimed at finding different appearances of leaf quantitative and qualitative attributes. Thus selecting 26 focal points (16 society in Bane and 10 society in Marivan areas), 390 leaf samples were collected and 13 morphological characteristics including 6 quantitative and 7 qualitative attributes were defined. Finally, observed data entered as inputs in a Nested Completely Randomized Design (CRD), for processing in Mstatc, Minitab and Genstat. The leaf quantitative resultes description show that leaf area and nerve number were the most and less variable attributes with ranges of 5.5- 60 cm and 6- 15 pairs and CV = 37% and 15%, respectively. Also, the qualitative results show that this species leaves have stellate tomentum or without hairs, which 90% of the samples were tomentose below and 55% were non- tomentose over. Blade was observed in 3 forms: obovate (96%), ovate and oblong. Margins forms were lobed (95%), siuate or entire. Leaf base was rounded, subcordate and attenuate, from which 63% had rounded base. Leaf apex forms were obtuse (%55) and rounded, also margine teeth apex forms were acute (73%) or rounded.
