Structural features of leaf mesophyll in Festuca pratensis (Poaceae)

摘要

Structural features of the leaf mesophyll in a typical mesophytic grass Festuca pratensis (Poaceae) were studied. Usually the mesophyll of festucoid grasses has been described as homogenous. However, two types of cells were observed in the mesophyllof Festuca pratensis: elongated cells located under the epidermis and rounded cells in the central part of the mesophyll. These types of cells differ from each other by their size and the number of chloroplasts.
