Effect of C.C.C. [2-(chloroethyl)] trimethyl ammonium chloride on growth and sporulation in Fusarium oxysporum f. udum (butl.) Sn. et H.
In Fusarium oxysporum f. udum sporulation of macroconidia was completely inhibited due to the influence of C.C.C. [2-(Chloroethyl)] trimethyl ammonium chloride). Microconidial proliferation, on the other hand, was adversely affected and with increase in concentration of this compound a parallel and proportional decrease in the amount of microconidia was found. Size of microconidia, too, showed a concomitant decline. Although the size of the chlamydospores was also reduced, a tremendous increase in its population was evident, showing a positive response in favour of C.C.C. addition. Fungal mat accumulation, another important aspect of growth, did not evince any inhibitory pattern, compared to the progressive increase in C.C.C. amoung in younger cultures. In older cultures (15-day old), an initial depressing shock of C.C.C. addition could be seen. However, after stepwise and gradual adjustment to the new environment the same positive response of mycelial growth was discernible, although in a less degree than that of the young cultures.
