Abstract

This work was designed to evaluate morphologic and micromorphological properties of leaf, cone and seed of some Juniperus species from Turkey: Juniperus drupacea (Caryocedrus section), Juniperus communis var. communis, Juniperus communis var. saxatilis, Juniperus oxycedrus subsp. oxycedrus, Juniperus oxycedrus subsp. macrocarpa (Juniperus section). Features of Juniperus species of leaf, cone and seed are investigated by Leica S8 Apo digital photomicrograph system and Jeol JSM 6490LV scanning electron microscope. The leaves usually carry double stomatal band on the inner surface except that J. communis subspecies. The resin pits number on the seed surface is varied 1-11. This resin pits on the seed surface was not observed in J. drupacea

Highlights

  • The genus Juniperus L. (Cupressaceae) is composed of evergreen shrubs or trees which form extremely different genera with taxa found from sea level to above the timberline

  • J. communis var. communis and J. communis var. saxatilis leaves have a single stomatal band on the inner surface

  • J. communis var. communis leaves are acute or acuminate at apex, J. communis var. saxatilis leaves are acute at apex

Summary

Introduction

The genus Juniperus L. (Cupressaceae) is composed of evergreen shrubs or trees which form extremely different genera with taxa found from sea level to above the timberline. The genus is monophyletic, consists of 75 species and is divided into three sections according to the relationship of leaf form, female flower features and cone scale to the seed bud The basic morphological features of leaves, cones and seeds in three populations of J. oxycedrus subsp. Alpina (Suter) Čelak and J. deltoides Adams) from Balkan Peninsula They showed that the anatomical features of leaves and stems of Juniperus genus have taxonomic importance at the species and infraspecies levels. The morphological properties of leaves, cones, seeds of some Juniperus species native to Turkey. We analysed the morphological properties of leaves, cones and seeds of Juniperus naturally growing in Turkey in the Juniperus and Caryocedrus sections and determined morphological differences between the Juniperus species
