Colony color ISOLATE PDA CMA MALT Fus-01 Pink White White Fus-02 Light pink White Purple Fus-03 Light pink White White and purple Fus-04 Light pink White Violet TABLE 7--Length, width, number of septa and shape of macro and microconidia, and production of chlamydospores
of Fusarium oxysporum isolates.
Experimental germ tube induction was also a laboratory designed adaptation of the routine microscope slide culture of yeasts for chlamydospore
Though no efforts were performed to study the Fom reduction mechanism in our bacterial strains, Elad and Baker  introduced siderophore production in cucumber with reducing chlamydospore
germination in F.
corn meal agar, corn meal agar with Tween 80, rice extract agar, rice extract agar with Tween 80, etc.) that is observed microscopically for the presence of yeast cells, pseudohyphae and chlamydospores
. (9,10) Since both methods above demand microscopic observation that requires considerable skill and experience, there is a need to develop alternate tests that are equally sensitive and specific, but require less technical expertise, are hence easily interpretable and need shorter incubation time.
moniliforme isolated from different hosts based on the production of microconidia, macroconidia, chlamydospores
, gibberellin and fusaric acid.
On the other hand a surprising result was obtained where 36 strains failed to produce germ-tube and out of these 2 were positive for chlamydospores
coupled with results of carbohydrate assimilation and chromogenic agar these were identified as C.
In some cases infectious source in the form of chlamydospores
can be brought into vigorous trees with side drought by insects-xylophages, flown out of stressed trees.
palmivora produces large chlamydospores
and is easily distinguished from P.
Symptoms: The affected canes produce long, black whip-like and coiled or curved shoots, which are covered with a thin silvery membrane, containing masses of chlamydospores
of the fungus.
However some authors consider it to be polymorphic exhibiting several different morphological forms including budding yeast cells (blastospores, blastoconidia), pseudohyphae (elongatged yeast cells that appear as filamentous cell chains), true hyphae and chlamydospores
