FUNGI ASSOCIATED WITH PISTACIA VERA
ZAKIA BILGRAMI AND ABDUL GHAFFAR
Abstract
Using ISTA techniques, 9 genera and 22 species of fungi viz., Alternaria alternata, A. tenuissima, Aspergillus candidus, A. clavatus, A. jlavus, A. fumigatus, A. niger, A. sulphureus, A. terreus, A. wentii, Aspergillus spp., Chaetomium spp., Cladosporium sp, D. state of Cochliobolus spiciJer, Fusarium equiseti, F. oxysporum, Fusarium spp., Penicillium camemberti, P. decumbens, Penicillium spp., Rhizopus sp., and Trichodenna harzianum were isolated from different parts of pistachio nuts collected from different parts of Pakistan. Of these, A. jlavus and A. niger were found predominant. The cotyledons were infected by greater number of fungi with less infection in shell, seed coat and axis (radicle and plumule). Less number of fungi were isolated by deep freezing method as compared to agar plate and blotter methods. Sterilization of seeds with 1% Ca(OCI)2 reduced the infection of Aspergillus species only.
