Estimation of interrelationships among some quality factors of jute seeds

Abstract

The storage mycoflora associated with seeds of 21 accessions of Corchorus capsularis L.
were isolated and identified. Blotter, Paper towel and Agar plate methods were used to
isolate the fungi associated with seeds. A total of ten species of fungi viz. Aspergillus flavus,
A. fumigatus, A. niger, A. terreus, Curvularia lunata, Colletotrichum corchori, Fusarium
oxysporum, Eurotium sp., Penicillium sp. and Rhizopus stolonifer were isolated from the
selected jute seeds. Aspergillus spp. and Colletotrichum corchori were predominant in most
of the jute accessions. Accession No. A‐3047 showed the highest fungal incidence and
Accession Nos. A‐3361, A‐2734 and A‐877 showed the lowest. Accession No. A‐3361
showed the highest seed germination while Accession No. A‐3309 showed the lowest.
Mortality of seedling showed the highest in Accession No. A‐3309 and the lowest in
Accession No. A‐3361. Physical purity of seed recorded the highest in Accession No. A‐
3361 and the lowest in Accession No. A‐3309. There were negative correlation between
percentage of fungi and percentage of germination and between percentage of fungi and
physical purity of seeds. Positive correlation was observed between percentage of fungi
and seedling mortality and between purity of seed and germination of seed.
