Abstract:
Twenty wheat seed samples collected from south western region of
Bangladesh were tested for seed borne fungi, germination and seedling
vigor, following different methods namely blotter method, rolled paper
towel method and deep freezing blotter method. Water agar test tube
seedling symptom test were also done. Seed borne fungi viz Bipolaris
sorokiniana , Aspergillus flavus, Aspergillus niger, Alternaria tenuis,
Fusarium moniliforme, Penicillium spp., Curvularia lunata and
Pyricularia grisea were isolated from three wheat varieties Shatabdi,
Prodip and Sonalika. Incidence of seed borne fungi were recorded and
compared to different seed health testing methods. Incidence of different
seed yielding fungi ranged from 0.33 to 26.33% and 0.67 to 30.00% in
blotter paper and deep freezing blotter method, respectively. Seed
germination percent ranged from 2.73 to 66.40% and 60 to 81% for rolled
paper towel method and seedling symptom test respectively. Percent
normal seedling ranged from 480.0 to 1964 for Shotabdi, 1450 to 1844 for Prodip and 1130
to 1796 for Sonalika variety .
