From observations of 5000 zoosporangia and sporangiophores, isolates showed different proportions of the oval form, zoosporangia size, and sporangiophores dimension (Table 3).
There was no relationship between morphology of zoosporangia and sporangiophores (Table 3) and virulent (Table 1) and aggressiveness characteristics (Table 2) for the races used in our study.
After 13 days of infection of the sunflower inbred line 'FU', the zoosporangia and
sporangiophores suspensions for 20 single zoosporangium 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).
Lycopersicon Non speptate mycelia Mucor Sp esculentum with branching
sporangiophores; columella pyriform, ellipsoidal, pointed conical Lycopersicon Micro-conidia, ovoid to Fusarium esculentum ellipsoidal in shape are oxysporum borne on simple phialides.
Sporangia borne on
sporangiophores: 0 = absent; 1 = present.
