Title: Leaf epidermal and gross morphological adaptations in salix nigra marsh (salicaceae) in relation to environmental pollution

Abstract

Eleven populations of Salix nigra Marsh. (black willow) in the mid-southern part of the United States were analyzed to determine the relationship between environmental contamination and variation in leaf epidermal and leaf morphological patterns. Plant populations of polluted habitats exhibited a decrease in leaf length and leaf width. Furthermore, stomatal frequency values, size of the largest stoma, and the epidermal wall undulations were reduced in these plant populations. Subsidiary cell complex remained unaffected by environmental pollution. 17 refs., 1 fig., 4 tabs.
