چکیده مقاله:

Fungi associated with sugar beet cyst nematode (Heterodera schachtii Schmidt) in W. Azerbaijan were isolated from different stages during 2002-2004 and studied. Some 300 fungal isolates were obtained. In this paper, 16 species belonging to nine genera are identified. Among them, three species viz. Lecanicillium aphanocladii, Myrothecium verrucaria andPlectosporium tabacinum are as new records to the mycoflora of Iran. Six species viz. Acremonium kiliense, Lecanicillium aphanocladii, Myrothecium verrucaria, Plectosporium tabacinum, Acremonium sclerotigenumand Fusarium sulphureum are isolated and reported on sugar beet cyst nematode for the first time.

evaluation of resistance of some sugar beet genotypes to beet cyst nematode under greenhouse conditions

resistance of 11 genotypes of sugar beet to cyst nematode was evaluated in two separate greenhouse experiments in completely randomized design. in each experiment, 50 seedlings of each genotype were inoculated with 1000 nematode larves in several times. after 9 weeks, the number of cysts on each plant was counted. data were analyzed with sas program. the results showed that the genotypes differ...

evaluation of different sugar beet populations for resistance to beet cyst nematode (heterodera schachtii schmidt(

in this research, 30 sugar beet breeding populations developed by crossing of sugar beet monogerm and multigerm male strile lines with nematode resistant wild sources (w-1009 contaning resistance gene from beta procumbens and w-1010 contaning resistance genes from beta maritima) were compared with resistant and susceptible checks with respect to nematode resistance and yield. the experiments we...

The composition of the cyst wall of the beet cyst-nematode Heterodera schachtii.

1. Cyst walls of the beet cyst-nematode (Heterodera schachtii Schmidt) were obtained by sieving a suspension of crushed cysts; about 15mg of dried cyst walls was obtained from 1000 cysts. 2. The cyst walls contained 68% protein calculated from nitrogen content. Glutamic acid, glycine, proline and hydroxyproline made up about 54% by weight of the amino acids obtained on acid hydrolysis. 3. Minor...

Detecting creeping thistle in sugar beet fields using vegetation indices

In this article, we address the problem of thistle detection in sugar beet fields under natural, outdoor conditions. In our experiments, we used a commercial color camera and extracted vegetation indices from the images. A total of 474 field images of sugar beet and thistles were collected and divided into six different groups based on illumination, scale and age. The feature set was made up of...

construction of vector fields with positive lyapunov exponents

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

studies on disinfection of the depot soil infested with sugar beet cyst nematode by soil solarization and manure

sugar beet cyst nematode (heterodera schachtii schmidt) is transferred to sugar factories along with the sugar beet root and its surrounding soil, so called depot soil. because of high infestation and the possible transfer and distribution of this soil, disinfestations of the depot soil should be taken into considerations. in order to assess the possibility for disinfestations of the depot soil...
