SEED BORNE MYCOFLORA OF GROUNDNUT SHAZIA RASHEED, SHAHNAZ DAWAR, A. GHAFFAR AND S. SHAHID SHAUKAT
Abstract:
Using blotter, agar plate and deep
freezing method as recommended by ISTA, the seed borne mycoflora of 12
groundnut seed samples collected from different localities of Pakistan
was examined. Of the 14 genera and 28 species of fungi isolated, 18
fungal species viz., Absidia corymbifera (Cohn) Sacc and Trotter,
Alternaria citri Ellis and Pierce apud Pierce, Aspergillus
awamori Nakazawa, A. candidus Link ex Link, A.
japonicus Saito, A.luchuensis Inui, A. panamensis
Raper & Thom, A. penecilloides Spegazzini, A. terricola
Marchal, A. terreus Thom, A. wentii Wehmer,
Chaetomium globosum Kunze ex Steud., C. indicum Corda,
Cladosporium oxysporum Berk. & Curt, Paecilomyces variotii
Bain,Syncephalastrum racemosum Cohn ex Schrot, Trichoderma
hamatum (Bonord) Bain and Tricothecium roseum (Pers) Link
ex Gray do not appear to have been reported from Pakistan on groundnut
seed. Macrophomina phaseolina, Rhizoctonia solani, Fusarium solani,
F. oxysporum, Aspergillus flavus and A. niger were
found predominant. Higher number of fungi were isolated where blotter
method was used as compared to agar plate and deep-freezing method.
Surface sterilization of seeds reduced the incidence of A. flavus
and A. niger.
