This experimtient was conducted to study the effect of cementing dust that was rising from the cement plant and accumulated on the leaves of pistachio trees at Muslimyah village and compared with similar trees in the Naqarin village. The results showed that the average of evapotranspiration decreased as temperature rise in August to €.179 mg/g/h in Muslimyah village versus 0.203 mg/grh in Naqarin, while the average of evapotranspiration in May does not exceed 0.465 mg/gr/h for trees of both Muslimyah and Naqarin.

The results also showed tow leaf growth at the cement dust potiuted area as compared with tree leaves at Nagarin area Full leaf area is 170 cm² versus 81cm² of Muslimyah tree leaves. Dust wad affected Chlorophyll concentration, which decreased to one-third chlorophyll Concentration in the Muslimiyati vihage as compared with the Naqarin village. The overall negative influence of some physiological events reflected on the trees growth, at which shoots length has been affected, in addition to the number of the remaining buds in the dust polluted fietas decreased to 16% versus 44% of the remaining buds of the Naqarin fields and this in tum had a negative impact on the tree productivity and fruit quality. The results showed some difficulties

when the DNA extraction did from polluted leaves as compared with unpolluted leaves that where collected from other places.

Key words; pistachio, cementing dust, evapotranspiration, chlorophyll, DNA extraction.
