Plant roots interact with a wide variety of rhizospheric microorganisms, including bacteria and the symbiontic arbuscular mycorrhizal (AM) fungi. The mycorrhizal symbiosis represents a series of complex feedbacks between plant and fungus regulated by their physiology and nutrition. Despite the widespread distribution and ecological significance of AM symbiosis, little is known about the potenti...

آگاهی از مراحل فنولوژیکی گونه‌هایی که ترکیب یک جامعه گیاهی را تشکیل می‌دهند، اهمیت قابل ملاحظه‌ای در تعیین مدیریت علوفه، زمان چرا و مدیریت چرای دام برای رسیدن به اهداف تولید پایدار و همچنین برای مدیریت عوامل مطلوب و غیرمطلوب گونه‌ها دارد. مطالعه فنولوژی گیاهی برای پایش، مدیریت و حفاظت اکوسیستم مهم و حیاتی می‌باشد. در این تحقیق فنولوژی دو گونه بوته‌ای Thymuskotschyanusو Artemisiaaucheriدر سایت ...
Abstract This paper presents a quantitative account of vegetation–environmental factor relationships in arid rangelands. Vegetation cover was recorded using Braun-Blanquet combined abundance-cover scale in each quadrat. Within each quadrat, one profile was dug and soil samples being taken at 0-20cm and 20-100cm depths. Under study physical-chemical characteristics included texture, lime, orga...
This study aimed to investigate plant species diversity in the ecological species group in relation to the environmental factors. A study area of 216 ha in the southeast of Baghmalek on which seventy 20×20 m plots were established according to the random-systematic method was selected. Soil properties and physiographic factors were recorded at each plot. Herbaceous species composition was recor...
