به منظور شناسایی قارچ های همزیست ریشه گیاهان زینتی، از ریشه و خاک 7 گیاه زینتی اسپاتیفیلوم، برگ انجیری، سینگونیوم، پوتوس، سنسوریا، مارچوبه و یوکا از 3 گلخانه استان گلستان نمونه برداری صورت گرفت. برای استخراج و جداسازی هاگ قارچ های میکوریز آربوسکولار از روش الک تراستفاده شد و سپس هاگهای جداسازی شده شناسایی شدند.پس از رنگ آمیزی ریشه ها، درصد ریشه های میکوریزایی، جمعیت هاگ ها و تنوع (تعداد)آنها ان...
The aim of this study was to assess the feasibility of using temporal temperature gradient electrophoresis (TTGE) of PCR-amplified 18S rDNA fragments of different Glomus species for their detection and characterization. Screening of Glomus clarum, Glomus constrictum, Glomus coronatum, Glomus intraradices, Glomus mosseae and Glomus viscosum by PCR-TGGE revealed that the NS31-AM1 region of the 18...
An increasing demand for organic produce, coupled with the need to reduce reliance on diminishing resource of rock phosphate, has bolstered interest in use arbuscular mycorrhizae (AMF) as a biofertilizer. AMF are symbiotic fungi that colonize roots most crops and transfer nutrients from soil their hosts exchange carbon. While past studies have shown mixed communities grown field can increase yi...
This study was conducted to evaluate the population of the arbuscular mycorrhizal fungi (AMF) in the semi-rid agro-ecosystem of North Jordan and to evaluate the effect of the biotic and abiotic factors on AMF population. Soil samples were collected from 12 locations where several soil samples were collected from each location. The collected soil samples were analysed for chemical and physical p...
UNLABELLED Although only recently described, Colletotrichum boninense is well established in literature as an anthracnose pathogen or endophyte of a diverse range of host plants worldwide. It is especially prominent on members of Amaryllidaceae, Orchidaceae, Proteaceae and Solanaceae. Reports from literature and preliminary studies using ITS sequence data indicated that C. boninense represents ...
The aim of the study was to determine effect a combination mycorrhizal fungi and watering intervals on kayu kuku (Pericopsis mooniana) grown gold tailings media. This research conducted at green house Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi branch for 4 months (March-July 2019). used factorial randomized block design (CRD) with two factors being tested, first including no AM...
میکوریزا از همزیستی بین ریشه ﮔیاه و ریسه قارﭺ بوجود می ﭐید. همزیستی میکوریزا تحمل ﮔیاه را در برابر عوامل ﺁسیب رسان به ﮔیاه, مانند تنش خشکی و شوری افزایش می دهد, افزایش زیتوده را باعث می شود و در نتیجه در توسعه ﮔیاهان در بیشتر اکوسیستم ها ﻣﺆثر می باشد. ﭘارک ملی تندوره با مساحت 73435 هکتار در ناحیه خشک شمال خراسان واقع شده است. خصوصیات طبیعی و تفاوتهای اقلیمی بین نقاط ﭘست و مرتفع اینﭘارک باعث تنو...
Phytoextraction involves use of plants to remove toxic metals from soil. We examined the effects of phytoextraction practices with three plant species (Silene vulgaris, Thlaspi caerulescens, and Zea mays) and a factorial variation of soil amendments (either an ammonium or nitrate source of nitrogen and the presence or absence of an elemental sulfur supplement) on arbuscular mycorrhizal (AM) fun...
The effect of arbuscular mycorrhizal fungi (AMF) on industrial tomato (Lycopersicon esculentum Mill. cv. Isma F1) cultivated in North-Eastern Algeria was evaluated under greenhouse and field conditions in a vertisol soil intended for the cultivation of industrial tomato. In the greenhouse, a commercial AMF inoculum and native fungal isolates consisting of Funneliformis mosseae and Septoglomus c...
