The phialides produce chains of uninucleate conidia after repeated mitotic division and cytokinesis. |
|
Microscopically, the fungus produces solitary oval to dumbbell-shaped conidia on short, unbranched conidiophores lateral to septate hyphae. |
|
This process terminates in the production of asexual spores, the uninucleate conidia. |
|
Spores or conidia are carried from the soil surface or debris to the plant by wind or splashing rain. |
|
Conidiophores terminally differentiate at the tips to yield multinucleated asexual spores, termed conidia. |
|
In many plant pathogenic fungi, conidia are the infectious propagules responsible for initiating infection as well as disease dissemination. |
|
Fungi of this genus produce characteristic darkly pigmented, septate hyphae or conidia. |
|
Small round conidia were attached to short simple conidiophores, resembling lollipops. |
|
Some fumigants can work as an activator by triggering the development of dormant conidia. |
|
Microscopically, thin branching hyphae with pyriform conidia can be seen. |
|
If conidia are not controlled, they greatly magnify the amount of scab in an orchard in a very short period of time. |
|
Morphological mutants were grouped in a class with yellow conidia and other with pale vinaceous conidia as opposed to the green wild type conidia. |
|
Under natural conditions, M. populorum spreads by ascospore dispersal and wind-borne conidia. |
|
Secondary spread by conidia occurs in rain and wind and, in Côte d'Ivoire, a hemipteran insect, Dysdercus sp. |
|
Usually, the colour of visibly moldy material comes from conidia, ascocarps, pycnidia and, in the case of melanized fungi, the mycelia. |
|
Finally, neither soil texture nor ionic strength affected the infectivity of conidia of both fungal strains to C. capitata puparia. |
|
Few lichen fungi produce conidia, a type of asexual spore common among ascomycetes. |
|
If the pigmentation is in the conidia, it can be removed through vacuuming or brushing the artifact. |
|
The spots rapidly increase in size and number and, under moist conditions, curled pink tendrils of conidia are seen. |
|
Wait 1 to 2 minutes so that the conidia fall down through the tower onto the leaf discs. |
|
|
The disease cycle is quite complex but it is thought that the main means of dissemination is wind dispersal of secondary conidia. |
|
Immersion in a bath of 70 percent alcohol and 30 percent water will kill active mould and dormant conidia. |
|
The small conidia are not infective and do not germinate on artificial media. |
|
Take spores from a cotyledon already covered with conidia and deposit them on a leaf taken from a young plant. |
|
Apple scab is a disease that develops in two phases: primary infections caused by ascospores and secondary infections caused by conidia. |
|
The ascospores and conidia thus formed play an important role in the primary infections. |
|
The conidia are produced in lesions that develop on the leaves and fruit. |
|
The tube was vortexed for 2-3 min to dislodge conidia from the insect and the concentration of conidia was determined using a haemocytometer. |
|
New crops of conidia can be produced every 3 to 14 days. |
|
Production of thermotolerant entomopathogenic fungal conidia on millet grain. |
|
In one area, brown fruiting bodies were present, characterized by a vesicle covered with a layer of sterigmata supporting chains of conidia. |
|
In early spring, bud scales infected the previous year develop and form conidia, which infect the basal portion of young clusters and produce black sporulating lesions. |
|
Similar to M. dearnessii, but the hyaline conidia are less adapted to exposure and thus less likely to be transported by methods other than rain-splash. |
|
Sometimes conidia are extruded through ostioles in whitish cirri. |
|
After heavy summer rain, the fungus may come to the soil surface and form large tawny mycelial mats, 10-20 cm in diameter and 0.6 cm thick, on which conidia are borne. |
|
The species is proposed as new because of DNA sequence differences, yellow-orange pigmentation of the cultures, absence of conidiophore branching, and comparatively long conidia. |
|
It forms brown to black colonies with hyaline or brown phialides, which are slender subcylindrical with a flared collarette and spherical, cylindrical, or allantoid conidia at their apex. |
|
Togawa M Effect of sterilization methods, plant varieties and leaf stages on conidia and perithecia formation in genus Fusarium in CLA-culture. |
|
Perithecia are formed about 3 years after conidia in erumpent, flattened, hard, black stromata which have a thin, white, pruinose surface layer when young and are up to a few millimetres across. |
|
Amounts of conidia formed on leaves decrease after summer has passed. |
|
|
They are characterized by hyaline, ellipsoid, oblong, reniform, allantoid to suballantoid conidia borne on a single locus on monophialidic conidiogenous cells. |
|
Conidia with parallel lateral walls and round borders were considered cylindrical, and those with some thinning at the edges were considered ovoid. |
|
Conidia in washing suspensions were counted using a haemocytometer. |
