Leaf Stomatal Characteristics of Some Species in Bush Form Used in Kastamonu Urban Landscape

Abstract

Nowadays, the rapidly increasing population has brought along many problems such as concretion, air pollution, and traffic density. It is known that parks and gardens, which are an important element for the urban landscape, not only balance the human-nature relationship in cities, but also improve urban living conditions. Parks and gardens that utilize urban areas from a functional and aesthetic point of view to meet the recreational needs of people, to recover the lost nature and to create healthy living spaces are extremely important. In this study, it was aimed to determine the leaf stomatal characteristics of Buxus microphylla Siebb and Zucc, Prunus laurocerasus L, Ligustrum delavayanum Har., Berberis thunbergii DC., Ilex aquifolium L., Euonymus japonicus var. aureomarginatus Rehder, Cotoneaster lacteus W.W.Sm., Mahonia aquifolium (Pursh) Nutt., Pyracantha coccinea M. Roem. species, one of the species used in the park, garden and central refuge landscaping studies in Kastamonu province. With micromorphological investigations, stomatal characteristics were determined by SEM on the species used in the study. With respect to stomatal density in the unit area on species, it was determined that Pyracantha coccinea species had the maximum stomatal density (81) while Cotoneaster lacteus species had the minimum stomatal density (10). Furthermore, it was determined that Prunus laurocerasus (34.82 µm) had the mean longest stomatal length and Mahoni aquifolium (7.183 µm) had the mean shortest stomatal length.
