Dual role of KHCO₃ priming: reduces seed-borne pathogens on sorghum seeds and promotes seed germination.

ABSTRACT:

Background

Seed-borne diseases have seriously affected the sustainability of sorghum cultivation in China as the demand for organic products in the winemaking industry has limited the use of chemical fungicides.

Results

This study conducted a comprehensive analysis of fungal diversity in sorghum seeds from three major growing regions in Guizhou Province. Using a combination of traditional tissue separation and high-throughput sequencing, we identified Colletotrichum, Fusarium, Cladosporium, and Alternaria as dominant fungi. Pathogenicity tests revealed that strains GD202206, GD202219, and GD202242 were pathogenic and were identified as C. sublineola through morphological and multi-locus phylogeny analysis (ITS、CAPDH、ACT、CHS-1 and TUB2). 16 fungicides for seed priming experim
