چکیده
Dust from cement factories and sand crushers can cause stress by depositing on the leaves. Accordingly, in areas that are often exposed to such problems, it is important to investigate its effect on plant growth and physiology. This experiment was simulated to investigate dust deposition on soybean leaves and their physiological characteristics. The experiment was carried out on soybean [Glycine max (L.) Merr. Var. Hobbit] via factorial in the form of randomized complete block design (RCBD) with three replications in ۲۰۱۶ and ۲۰۱۷. The factors included the type of dust (cement, clay, and sand), each of them ۲۰ g m-۲ at different stages of soybean growth (V۳ (third-node), R۱ (beginning bloom), R۳ (beginning pod) and R۵ (beginning seed)). Plant traits measurements included chlorophyll content, stomatal conductance, catalase activity, soluble sugar, chlorophyll fluorescence (Fv/Fm), and seed yield. The results proved that dust deposition had significant effects on reducing stomatal conductance, photosynthetic pigments, Fv/Fm, and soybean yield. Finally, the use of cement dust from stage V۳ led to a significant reduction in some traits. In this treatment, the amount of damage was higher with the increase of dust deposition period.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
