Performance evaluation of selected tree species growing alongside state highway, Himachal Pradesh, India

Author(s): K Haseena, SK Bhardwaj
Abstract: The response of plants to air pollution at physiological and biochemical levels can be understood by analyzing the factors that determine resistance and susceptibility. Thus field study helped in understanding the seasonal variation in the biochemical parameters and evaluating the performance of the common tree species growing around the Nauni-Solan State Highway of Himachal Pradesh. The assessment of the API with respect to the selected plant species was observed to lie in the range poor to excellent. Among the selected species the order of API was: Toona ciliata >Pinus roxburghii = Pistacia integerrima > celtis australis = Jacaranda mimosifolia = Grewia optiva. However, certain plants like Toona ciliata have shown their adaptability to the stress caused by the pollution. Hence, Toona cliata with higher tolerance and anticipated performance index can be suggested for plantations alongside the State Highway so as to intercept the air pollutants which are hazardous to human and other living organisms.
