Inspection of dry seeds revealed that the seed samples contained apparently healthy se eds, discolored seeds and
shriveled and malformed seeds. The germination percentage was recorded higher in Changeable rose (88.50%)
and lower in Margosa tree (41.00%) in blotter method. Germination percentage was recorded higher in blotter
method than pot soil test. Fungi were detected by blotter method both with and without pre -treatment of seeds.
Hgcl
(0.01%) solution was used for pre-treatment. Seven fungal species viz. Alternaria tenuis, Aspergillus flavus,
Aspergillus niger, Curvularia lunata, Fusarium oxysporum, Penicillium sp and Rhizopus stolonifer were recorded from
without pre-treated seeds while only three species of fungi viz. Alternaria tenuis, Curvularia lunata and Fusarium
oxysporum, were recorded from pretreated seeds. All these fungi are new records for seeds of medicinal plants in
Bangladesh.
