Physiological functioning of Lagerstroemia speciosa L. under heavy roadside traffic: an approach to screen potential species for abatement of urban air pollution.

摘要: The mitigation potential of avenue tree species needs a sound understanding, especially for landscape planning or planting on roadside, in city limits where there is huge traffic due to more number vehicles. A preliminary study was conducted investigate the impact heavy movement and pollution thereof physiological functioning Lagerstroemia speciosa trees planted roadside terms carbon absorption, adaptive behavior. Trees exhibited reduced assimilation (36.7 ± 2.4%) transpiration rate (42.14 ± 2.9%), decreased stomatal conductance (66.85 ± 3.87%), increased resistance (212.2 ± 11.25%), leaf thickness (40.54 ± 3.25) water use efficiency (9.4 ± 0.87%), changes lead (179.31 ± 10.24%) proline (15.61 ± 1.92%) concentration tissues when compared less area (FRI campus). impacts were also witnessed form enhanced vapour pressure deficit air (63.18 ± 4.94%) (45.72 ± 3.25%), temperature (3.2 ± 0.16%) (9.0 ± 0.82%) along trees. It inferred that movements interrupt alteration surrounding environment as non-traffic areas. present provides baseline information further explore identify having significant improving urban environment.
