Conidial germination of Botryosphaeria
dothidea (anamorph: Fusicoccum) in sterile
distilled water and 1% sterile dextrose solution
was evaluated at 4, 6, 12, 24 and 36 h after
incubation. Also, it was described the anatomical
changes on pitahaya stems induced by this
fungus, collected in the field and artificially
inoculated in the laboratory. Conidial germination
was less than 30% in water and it was improved
when 1% dextrose was added to the water.
In 1% dextrose solution the germination was
90% after 4h of incubation and 100% at 6 h.
Pathogen germ tubes had entered through
wounds and sometimes through stomata and
hyphae colonized intra and intercellularly in
the parenchyma-chlorenchyma tissues. On
naturally and artificially diseased stems the
main alterations were: destruction of cuticle,
hyperplasia of epidermal and collenchymatous
hypodermal cells and conform the advance
of the pathogen a layer of lignified periderm
was formed surrounding the damaged tissues;
however, it couldn't stop the advance of the
pathogen and the cells that surrounded the
lesion suffered necrosis. Se evaluó la germinación de conidios de Botryosphaeria dothidea (anamorfo: Fusicoccum) en agua destilada estéril y en una solución de dextrosa 1% a las 4, 6, 12, 24 y 36 h de incubación. También, se describieron los cambios anatómicos en tallos de pitahaya inducidos por este hongo, tanto aquellos naturalmente infectados en campo como inoculados artificialmente en laboratorio. La germinación de conidios en agua estéril solo alcanzó el 30%, mientras que la adición de dextrosa al 1% mejoró la germinación. En una solución de dextrosa al 1% la germinación a las 4 h fue de 90% y del 100% a las 6 h. Los tubos germinativos del hongo penetraron a través de las heridas y algunas veces a través de los estomas y se multiplicaron inter e intracelularmente en los tejidos del parénquima-clorénquima. En tallos enfermos natural y artificialmente, las principales alteraciones fueron: destrucción de la cutícula, hiperplasia de las células epidermales e hipodermales colenquimatosas. Conforme el avance del patógeno se formó una capa de peridermis lignificada que rodeó el tejido dañado; sin embargo, no se detuvo el avance del patógeno y las células que rodeaban la lesión se necrosaron. |

Conidial germination of Botryosphaeria
dothidea (anamorph: Fusicoccum) in sterile
distilled water and 1% sterile dextrose solution
was evaluated at 4, 6, 12, 24 and 36 h after
incubation. Also, it was described the anatomical
changes on pitahaya stems induced by this
fungus, collected in the field and artificially
inoculated in the laboratory. Conidial germination
was less than 30% in water and it was improved
when 1% dextrose was added to the water.
In 1% dextrose solution the germination was
90% after 4h of incubation and 100% at 6 h.
