Foliar epidermis morphology in Quercus (subgenus Quercus, section Quercus) in Iran

Abstract

-The foliar morphology of trichomes, epicuticular waxes and stomata in Quercus cedrorum, Q. infectoria subsp. boissieri, Q. komarovii, Q. longipes, Q. macranthera, Q. petraea subsp. iberica and Q. robur subsp. pedunculiflora were studied by scanning electron microscopy. The trichomes are mainly present on abaxial leaf surface in most species, but rarely they appear on adaxial surface. Five trichome types are identified as simple uniseriate, bulbous, solitary, fasciculate and stellate. The stomata of all studied species are of the anomocytic type, raised on the epidermis. The stomata rim may or may not be covered with epicuticular. The epicuticular waxes are mostly of the crystalloid type but smooth layer wax is observed in Q. robur subsp. pedunculiflora. Statistical analysis revealed foliar micromorphological features as been diagnostic characters in Quercus.

Leaf epidermal features ofQuercussubgenusCyclobalanopsis(Fagaceae) and their systematic significance

“…These works established a terminology of leaf epidermal features of Fagaceae. Subsequently, the leaf epidermal features of a large number of oaks from Europe and Asia have been reported, especially from the Mediterranean region (Llamas et al ., ; Zhou, Wilkinson & Wu, ; Bussotti & Grossoni, ; Uzunova, Palamarev & Ehrendorfer, ; Luo & Zhou, ; Karioti et al ., ; Panahi et al ., ), Tschan & Denk, ). All these studies form a solid foundation for comparative analysis of the leaf epidermal features of this large genus.…”

Rapid and economical protocols for genomic and metagenomic DNA extraction from oak (Quercus brantii Lindl.)

“…This genus provides important economic benefits and high sociocultural value, and its role in water and soil protection in different regions of the world, such as Europe (e.g., UK, Slovakia, Czech Republic, Hungary, Austria, Germany, Italy, France, Ukraine, Belarus, and Moldova), North and Central America (e.g., USA, Mexico, Belize, Canada, Colombia, Guatemala, and El Salvador), and Asia (e.g., Iran and Indonesia), led to increasing attention to this genus (Nixon 2006;Heydari et al 2016). Quercus is the most frequent genus of the Fagaceae family in forests of Iran (Panahi et al 2012), and several species of oaks grow abundantly in Zagros forests in the west region of Iran. The most important species of the region exhibiting remarkable morphological variation are Quercus brantii Lindl., Quercus libani Oliv., and Quercus infectoria Oliv.…”

The taxonomic implication of leaf micromorphological characteristics in the genus Aruncus (Rosaceae)

“…These works established a terminology of leaf epidermal features of Fagaceae. Subsequently, the leaf epidermal features of a large number of oaks from Europe and Asia have been reported, especially from the Mediterranean region (Llamas et al, 1995;Zhou, Wilkinson & Wu, 1995;Bussotti & Grossoni, 1997;Uzunova, Palamarev & Ehrendorfer, 1997;Luo & Zhou, 2001;Karioti et al, 2011;Panahi et al, 2012), Tschan & Denk, 2012). All these studies form a solid foundation for comparative analysis of the leaf epidermal features of this large genus.…”
