The goal of each root canal therapy is cleaning and obturating the entire root canal system. A thorough knowledge of root and root canal morphology and a good anticipation of their possible morphologic variations are essential and will help to reduce endodontic failure caused by incomplete root canal preparation and obturation. In this study, one case of maxillary molar with two palatal roots ...
Root depth is one of the main parameters affecting soil moisture availability held within the plant root zone. This study was conducted to evaluate the trend of corn root development during the growing season in different irrigation methods with two water qualities, and distribution of roots in soil profile. The experiment was a split plot design with three main treatments (subsurface drip(SSD)...
Abstract In order to investigate the effects of nano silver and multi wall carbon nanotube levels on some morphological and physiological traits of faba bean the present study was done. This factorial experiment was conducted in a completely randomized design with three replications and two treatments with four concentrations (0,100,200 and 300 mgl-1). The results showed the total number o...
شناسائی وتعیین دامنه میزبانی عامل فیتوفترائی پوسیدگی ریشه وطوقه گوجه فرنگی با استفاده از روشهای ملکولی ومرفولوژیکی در استان فارس از گیاهان گوجه فرنگی (lycopersion esculentum mill) در استان فارس که دارای پوسیدگی و نکروز وسیع روی ریشه و طوقه ، و در قسمتهای هوائی علائم زردی و پژمردگی داشتند به طور مکرر یک گونه فیتوفترای هتروتالیک از ریشه اصلی روی محیط کشت اختصاصی parp)) جداسازی گردید. بااستفاده ...
Root system growth and development is highly plastic and is influenced by the surrounding environment. Roots frequently grow in heterogeneous environments that include interactions from neighboring plants and physical impediments in the rhizosphere. To investigate how planting density and physical objects affect root system growth, we grew rice in a transparent gel system in close proximity wit...
understanding of wheat root system is important in dryland conditions. root development, important factor in wheat production under water limiting conditions, can be affected by environmental factors especially nitrogen fertilizer. a field experiment was carried out to study the nitrogen rates and application times on root morphology of three rainfed wheat genotypes, using a split-splitplot bas...
