Evaluating Air Pollution Tolerance Index (APTI) of Two Plant Species from Industrial Area of Jodhpur

Jodhpur is the second largest district in state of Rajasthan. With growth population numbers vehicles along with industries have increased which affecting air quality Jodhpur. Plants a very close relationship nature and they act as sink for reducing pollution. Impact pollution on two plants namely Tabernaemontana Sesbania (vegetable humming bird tree) from heavy industrial area site (HI) Phase II were evaluated terms tolerance index (APTI) by analysing four biochemical parameters namely, total chlorophyll, ascorbic acid, relative water content (RWC), pH using standard methods. Fresh mature leaves collected every month August 2019 to March 2020 morning hours between 8.00 AM 9.00 number (between 4.00 PM) counted. Average APTI values found be 7.13 5.90 respectively hence both fall sensitive category. showed positive correlation pH, RWC, acid but negative chlorophyll Tabernaemontana, while with, pH. The was maximum October (2.0 1.66). Relative minimum November (RWC 41.79 36.81) (0.4487 0.2682) respectively.
