Anatomical and morphological features of a leaf Rosa rugosa Thunb. in different climatic conditions

The aim of the study was to assess the ability to adapt R. rugosa to different climatic conditions and to identify the most informative xeromorphic features that can be used in the selective work. The objectives of the study were to conduct morpho-anatomical analysis of adaxial and abaxial epidermis of the leaf, to study water regime and to determine the degree of drought re-sistance of plants and their ability to be adapted. The studies were carried out in phenological stage of “fruit formation” in Belgorod in 2009, and in Bryansk and Saint-Petersburg in 2014. The material was selected according to conventional method taking into account the age of plants and morphological address, the study of the epidermis and its structures was carried out using CM Levenhuk 320, video camera Levenhuk C310 NG, eyepiece micrometer MOB-1-15×U4,2, SEM Quanta 200 3D, calculating hereby the coefficient of tortuosity of anticlinal walls. The technique of Nikitsky Botanical gar-den was used to study water regime of plants...
