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...
Introdouction: Variations in root canal morphology pose a challenge for successful endodontic treatment. The root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). The occurrence of two palatal canals in one palatal root is quite rare. This report represents the case of a maxillary first molar...
Knowledge about the root system structure and the uptake efficiency of root orders is critical to understand the adaptive plasticity of plants towards salt stress. Thus, this study describes the phenological and physiological plasticity of Citrus volkameriana rootstocks under severe NaCl stress on the level of root orders. Phenotypic root traits known to influence uptake processes, for example ...
