Rillig, M. C. 2004. Arbuscular mycorrhizae, glomalin, and soil aggregation. Can. J. Soil Sci. 84: 355–363. Arbuscular mycorrhizae are important factors of soil quality through their effects on host plant physiology, soil ecological interactions, and their contributions to maintaining soil structure. The symbiosis is faced with numerous challenges in agroecosystems; in order to inform sustainabl...
در خاک های آهکی فسفر معمولا به صورت ترکیباتی نامحلول با کلسیم همراه بوده و گیاه غالبا از نظر جذب فسفر در این خاک ها دچار مشکل می باشد. به نظر می رسد برخی از ریز جانداران خاک نظیر باکتری های حل کننده فسفات (psb) و قارچ های میکوریزی آربوسکولار (am) قادر باشند با استفاده از مکانیزم های مختلف، فسفر را از شکل غیر قابل استفاده به شکل محلول و قابل استفاده تبدیل کنند. به منظور بررسی نقش باکتری های حل ک...
Effects of the mycorrhizal fungus Glomus intraradices on establishment of subterranean clover (Trifolium subterraneum L.) seedlings in saline conditions were studied in a glasshouse experiment. Growth and nutrient uptake were determined 10, 20 and 30 days after transplanting of mycorrhizal and nonmycorrhizal matched seedlings into soils with five different levels of salinity. Mycorrhizal plants...
Mycorrhiza is a mutualistic association between zone surrounding the root [2]. Although a lack in growth fungi and higher plants [1]. Different types of mycorrhizae response to VA-fungi inoculation in unsterilized soil was occur, distinguished by their morphology and to a also recorded, this result has been attributed to the fact certain extent, in their physiology. These include the that nativ...
In surveys in the Hawaiian Islands, mycorrhizae occurred frequently in epiphytic, nonorchidaceous angiosperms and pteridophytes. Both vesicular-arbuscular (VA) and ericoid mycorrhizae were present in epiphytes growing 1-3 m above the forest floor on dead and living tree trunks and on living tree ferns in montane wet forest sites. All eight angiosperm species were mycorrhizal, and 13 of 22 pteri...
Creating sustainable bioeconomies for the 21st century relies on optimizing the use of biological resources to improve agricultural productivity and create new products. Arbuscular mycorrhizae (phylum Glomeromycota) form symbiotic relationships with over 80% of vascular plants. In return for carbon, these fungi improve plant health and tolerance to environmental stress. This symbiosis is over 4...
