Morpho-histologic studies on three herbaceous species of railway track

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Changes in the morpholohy and leaf histology ofEuphorbia hirta L. (Euphorbiaceae),Boerhavia diffusa L. (Nyctaginaceae), andCleome viscosa L. (Cleomaceae) growing along a particular railway track have been studied in comparison with those individuals of these species growing well away from railway track to evaluate the effects of pollution and physical disturbances created by running of trains. In general, plants growing along the railway track showed a decrease in the size of whole plant, flowers and fruits, root-shoot ratio, length of root-system, stem diameter, fruit setting, and seed output. Also, leaf stomatal frequency, veinislet number and veinlet termination number increased while the palisade ratio decreased.
