Alstonia scholaris - Opis:
- Air pollution arises mainly from automobiles and industries is well known fact. Monitoring and detection by instrument cannot be possible everywhere however, indication from plant species by their alterations in leaf morphology and anatomy may be a suitable easy screening measurement. The present study aims to detect morphological features with special reference to gall quantification and anatomy of leaves of Alstonia scholaris R. Br., found in eastern Indian urban and suburban area that are exposed to vehicular emission. The results indicated alterations of leaf morphology along with length (L), breadth (B), L/B ratio and significantly increased (P < 0.001, 0.01 and 0.05) Air Pollution Index (API). It is concluded that vehicular emission can be monitored as an early indication through increased API in A. scholaris. Further research would be needed in relation to secondary metabolites alteration, biochemical and genetic parameters to know pollutant susceptibility as an indicator. In addition, anatomical abnormalities in gall formation as well as numbers were also pronounced in leaves exposed to various load of air pollution.
