Effect of temperature and some media and biotic factors on the growth of Fusarium oxysporum f.sp. lentis, and its mode of seed transmission (original) (raw)

Erskine, W.; Bayaa, B. and Dholli, M. 109(r, Effer:l of temFera'ure and some medie anC hi:iir fa:tc.rs or the growth of. Fusarium oxysporuml.sp. Ientisanil its mode of sced transmission. Arar. J.Pr. Prot. E(1): 3't 9. This study was conducted to determine the effects oi some r:ictors., namely temperature (10, 15, ':.(.), 25 and 30'C) and media (potato dextrose a}ar, lentit dextrose a}ar anri (Czapek), on the growth in vitro of \-tuarium oxysporufit f.tp. lentis in order to produce sufficient inoculum for the development of a screening technique, ES well as to clarify such aspects of disease epidemiology as mode of seed transmission and association with nematodes and antagonistic bacteria. The optimum temperature for fungal growth was 22"C. Maximum rnycelial growth and sporulation were obtained on ientil dextrose agar . In virro studies revealed an antagonistic effect between the fungus and a Pseudorfionas sp. isolate,i from infected soil. The following nematode ...
