The present study effects of pollutant particles from Bartm Cement
Factory on development of seeds and leaves of Taurus Cedar (Cedrus
libani Rich.) which in plantation area around the factory were examined.
For this purpose, seeds were collected from sampling trees located 200m,
400m, 600m, 800m and 1000m (control) and zermination percentage of
seeds, and total chlorophyll content of seedlings were determined.
Moreover, in the present study, the air movement around Bartin Cement
Factory and level of pollutants in sampling areas were also determined.
The directions of the prevailing winds around the cement factory were
North, and Northwest. From the aspect of pollutant material level, the
array of sampling areas was SP1>SP2>SP3>SP4>C. On the other hand,
evaluating the results of mean seed germination percentages, a
significant difference (P<0.01) was noted between control and seeds of
Taurus Cedar at various distances from are pollutant source. From the
aspect of the power of seeds collected with 3 repetitions from Taurus
Cedars located at various distances, it a significant difference
(P<0.01) was found between the control and experimental groups.
Accordingly, from both the aspects of mean germination percentage and
seed power, an apparent increase was observed from 400 m distance. On
the other hand, as the distance from cement factory increased, total
chlorophyll content in Taurus Cedar seedlings increases significantly.
Results of bilateral regression analysis evaluated exponential
relationship at level 97\% between these 2 variables
