Slow and unreliable infection in the greenhouse has been a barrier to research on Armillaria root disease. The existing infection assay takes 7-18 months for detectable infection, during which time the inoculum often dies, resulting in unequal challenge among plants. Because symptom expression and mortality are rare, presence or absence of infection, determined by culturing, is the only datum d...

abstract introductiion. there are a lot of edentulous patients who need complete dentures in any society. one of the most important problems of edentulous patients is remaining dental lesions. atrophy of maxillary or mandibular bone, infections abcesses, tumors and so on are among some other problems. in this study we tried to evaluate the panoramic radiography in order to detect these problems...

The use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. One of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. This research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...

We examined effects of mist quantity, topophysis (origin of cutting in the crown of 6-year-old trees), maturation state of the donor stock, and time of sticking on rooting and root system quality of cuttings representing five full-sib hybrid larch families obtained with Larix decidua Mill., L. laricina (du Roi) K. Koch, and L. kaempferi (Lamb.) Sarg. (Sieb. and Zucc.) Gord., as parents. Mist fr...

Bahia grass (Paspalum notatum) and industrial sweet potato (Ipomoea batatas) colonized by Glomus deserticola, G. etunicatum, and G. intraradices were grown in aeroponic cultures. After 12 to 14 weeks, all roots were colonized by the inoculated vesicular-arbuscular mycorrhizal fungi. Abundant vesicles and arbuscules formed in the roots, and profuse sporulation was detected intra-and extraradical...
