The effects of exhaust pollutants of generator on root and shoot length, root and
shoot weight, number of leaflets and leaf area, leaf and total plant dry weight of
Vinca rosea
and
Ruellia tuberosa
were studied. The treatment of exhaust pollutants produced significant effects
on root, shoot growth, number of leaflet and leaf area of
V. rosea and
R. tuberosa as compared
to control. The exhaust emission treatment decreased seedling dry weight of
V. rosea and
R.
tuberosa. The data showed that the exhaust emission significantly decreased the number of
leaflet and leaf area for both species viz.
V. rosea and
R. tuberosa as compared to control. A
significant decrease in the seedling growth performances of
V. rosea and
R. tuberosa resulted in
decrease in seedling dry weight and showed that the exhaust treatment affects the seedling dry
weight performance as compared to control treatment. It was found that the treatment of
exhaust emission from a portable powered generator fueled negatively affected the seedling
growth of
V. rosea as compared to
R. tuberosa. The findings may be helpful for plantation in
polluted area.
