After 13 days of infection of the sunflower inbred line 'FU', the zoosporangia and
sporangiophores suspensions for 50 isolates were obtained by grouping all sporulated cotyledons in a small container and adding 1 ml of physiological water for each cotyledon (9g NaCl + 1L sterilized water).
The
sporangiophores are unbranched; arise singly or in groups with well-developed rhizoids at the base.
The
sporangiophores or stalks may be lacking and a lamina or leafy component may or may not be present.
Isolated fungi were examined by using 10 x and 40 x magnifications on the microscope to identify hyphae, sporangia,
sporangiophores, conidia, conidiophores and some other morphological characters including growth pattern, colony texture and growth rate of the colonies onPDA(Promputthaetal., 2005).
elegans closely resembles Absidia species in producing pyriform, apophyseal, multispored sporangia on
sporangiophores which arise on stolons but typically not opposite rhizoids (Fig.
The axis or peduncle upon which the ovules are borne was originally dichotomized into uni-ovulate
sporangiophores.
Infected leaves from mature 7042(S) and HB 3 plants growing in the downy mildew field nursery at ICRISAT-Patancheru were detached, wiped clean of existing
sporangiophores using moist cotton wool and incubated in darkness in plastic boxes for 8 h at 20[degrees]C and 100% relative humidity.
