[ 1 ] - Effects of Artemisia sieberi extract on growth and nutrients uptake of Peganum harmala
This study was conducted to determine the effects of Artemisia sieberi extract (0.2%, 0.4%, and control) on germination, some morphological characteristics, photosynthesis pigments, and nutrients uptake of Peganum harmala. Results showed that the extract of A. sieberi had a significant effect on seed germination and morphological characteristics of P. harmala. The highest seed germination was c...
[ 2 ] - تأثیر همزیستی قارچهای گلوموس اتونیکاتوم و گلوموس اینترارادیسز بر شاخص کلروفیل برگ سورگوم در شرایط کمبود عناصر کممصرف در سیستم کشت بدون خاک
Beneficial effects of arbuscular mycorrhizal fungi (AMF) on plant growth have been widely reported. But there is a lack of information on the effect of this symbiosis in soil-less culture systems. Therefore, this experiment was aimed to investigate the effect of mycorrhizal symbiosis on leaf chlorophyll index of sorghum plants grown in perlite media under micronutrients deficiency conditions. T...
[ 3 ] - تأثیر کمبود برخی فلزات و اینوکلوم‌های دو گونه قارچ میکوریز آربوسکولار بر ترشح ترکیبات کی‌لیت کننده از ریشه گیاه گوجه‌فرنگی
Arbuscular mycorrhizal fungi (AMF) can affect their host plants growth through nutrient uptake enhancement. Determination of chelators (siderophores and phytosiderophores) in root leachates is of importance in order to account for the effects of AMF on nutrient uptake by plants. In this study, tomato plants were inoculated with either Glomus intraradices or Glomus etunicatum or left un-inoculat...
[ 4 ] - تأثیر دو گونه قارچ میکوریز آربوسکولار در شرایط کمبود عناصر کم مصرف بر pH آبشویه در طول رشد رویشی گیاهان سورگوم و گوجه فرنگی
در اغلب موارد کلنیزاسیون ریشه گیاهان با قارچهای میکوریز باعث افزایش جذب عناصر کممصرف میشود. برای تشخیص مکانیسم جذب عناصر کممصرف توسط قارچهای میکوریز آربوسکولار، اندازهگیری pH آبشویه میکوریز که معیاری از اسیدی یا قلیایی شدن ریشهسپهر و هیفسپهر است، ضروری بهنظر میرسد. این آزمایش بصورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی و در سه تکرار اجرا شد. فاکتور اول شامل قارچ میکوریز آربوسکولا...
[ 5 ] - تأثیر دگرآسیبی عصاره درمنه (Artemisia sieberi) بر خصوصیات سبزشدن و جذب عناصر غذایی کهور ایرانی (Prosopis cineraria)
DOR: 98.1000/2383-1251.1397.5.21.9.1.1578.41 Extended abstract Introduction: Allelopathic effects of plant on one another are one of the most important concerns in reclamation and rehabilitation of rangelands in Iran. Allelopathy refers to the deterrent effects of a plant on growth, development or emergence of another plant. One of the rangeland reclamation methods is planting suitable an...
[ 6 ] - Investigation of Dust Microbial Community and Identification of its Dominance Species in Northern Regions of Sistan and Baluchestan Province
Many studies have been done on various properties of dust and one of the most important characteristics of dust is the ability to carry different microorganisms from the source points. The aim of this study was to investigate the bacterial and fungal community of dust and to identify its dominance species in a single event of intense dust storm, in the northern regions of Sistan and Blauchestan...
