Abstract: 

Mulberry is used for planting development. This tree is one of the important species that planted in the Mobarakeh Steel Complex. This tree dieback has been a main managerial problem in recent years in the company. Environmental stress is one of the most important factors that influencing on species dieback. Absorption of heavy metals as an environmental pollutants, nutrient absorption, plant pigment and proline can determine the impact of stress on the occurrence of this phenomenon. The 2000 m2 plot was built in each area that planted by this species. Leaves complex sample of 5 trees were collected of healthy and unhealthy trees to compare of elements concentration. The results showed that the uptake of heavy metals including lead, mercury, cadmium and nickel in the leaves of unhealthy trees was higher than healthy trees, but the amounts of these elements were not toxicity in unhealthy trees. Absorption of macro and micro nutrients such as calcium, potassium, nitrogen, manganese, magnesium, iron, copper and zinc in the leaves of healthy trees was more than unhealthy leaves, but the amount of sodium and chlorine in the leaves of unhealthy trees were rather than healthy trees. This condition was indicative of salinity stress in the habitat. Water sources also indicate this phenomenon. Lack of soil fertility also created many problems for power plants. Soil fertility stresses was extended dieback of trees.
