چکیده

Carbon nanotubes (CNTs) are known to have many unique physical and chemical properties. Because of this features of CNTs have been used in agriculture to increase the crop yield, mainly in the germination process and growth.in this experiment, okra seedling were treated by 4 multi-walled carbon nanotubes (MWCNTs) ) 0, 50, 100 and 200 mg/lit(.After treatment, we measured effects of multi-walled carbon nanotubes (MWCNTs) on morphological and anatomical tissues (stem, root and leaf) characteristics of okra seedling plants. Results showed that grow parameters were increased under MWCNTs treatments. However these parameters were decreased by increase of MWCNTs concentration. In other hand, results of anatomical study showed that thickness of stem and root were affected by changes of cortex zone. This present study, showed that thickness of mesophylos layer and vascular region have been increased by low concentration of MWCNT, but these parameters have been decreased by high concentration. In this study indicated that moderate and high concentrations of MWCNTs treatments caused increase stomata index and decrease stomata length. Finally, it can be concluded that carbon nanotubes have a positive effect on low and medium treatments and in high concentrations have negative effects on okra seeds

اطلاعات بیشتر در مورد COI

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.
