Despite the importance of sulfur (S) for plant nutrition, the role of the arbuscular mycorrhizal (AM) symbiosis in S uptake has received little attention. To address this issue, 35S-labeling experiments were performed on mycorrhizas of transformed carrot (Daucus carota) roots and Glomus intraradices grown monoxenically on bicompartmental petri dishes. The uptake and transfer of 35SO4(2-) by the...

Indonesia is a tropical country that has natural forests and suitable for orchid species habitat, leading to more than 5,000 of orchids grow. The area the main distribution centre epiphytic orchids, one which Dendrobium, grows 1,000 throughout world. Orchid seeds are very small do not have an endosperm, making germination difficult in their habitat. Mycorrhizal association with plays role survi...

nitrogen and phosphorus are two of the essential nutrients that promote plants' growth and yield. deficiency of these nutrients in soil is usually compensated through application of chemical fertilizers. chemical fertilizers on the other hand have detrimental effects on environment in addition to decreasing quality of agricultural products. the present study was conducted to evaluate the e...

One benefit of incorporating poultry wastes and arbuscular mycorrhizal fungus (AMF) into soils is an increase in crop yield. However, experimental results vary depend on the kind wastes, setup, characteristics soil. Thus, underlying causes have not yet been fully understood. In other circumstances, inoculation amendment with may clear impact or negative impacts soil microbes plant growth. The e...

A common feature of mycorrhizal observation is the growth of the infection on the plant root as a percent of the infected root or root tip length. Often, this is measured as a logistic curve with an eventual, though usually transient, plateau. It is shown in this paper that the periods of stable percent infection in the mycorrhizal growth cycle correspond to periods where both the plant and myc...

The arbuscular mycorrhizal (AM) fungi, in concert with other soil dwelling microorganisms such as the so-called “plant growth promoting rhizobacteria”, play a pivotal role for natural soil fertility and stability, hence, for sustainable crop production. Appropriate management of the AM fungal community is crucial, especially in the tropics where the cultivated soils are notoriously fragile and ...

the common root rot of wheat caused by bipolaris sorokiniana is considered as an important disease of world wide distribution including iran. biological control of b. sorokiniana can be an effective method for control of this disease. for this purpose, the biocontrol potential of mycorrhiza glomus fasciculatum, pseudomonas fluorescens sh4 and a mixture of the two was evaluated for the common ro...
