摘要

Matriconditioning, controlled seed hydration by moistened carriers with high water adsorptive matric forces, has been proven to improve seed viability and vigor, plant growth and yield of various crops. Bioprotectants and/or chemical pesticides can be used in combination with matriconditioning, the process being biomatriconditioning. Biomatriconditioning with the biofungicide clove oil 0.06% or 0,1% were effective seed treatments to improve the vigor and relative speed of germination while reducing percent of Colletotrichum capsici, a seedborne pathogen causing anthracnose disease in hot pepper seeds. Biomatriconditioning with clove leaf powder was better than matriconditioning plus fungicide in reducing infection level of C. capsici-infected hot pepper seeds, and improving seed viability and vigor for up to 24 weeks storage at ambient temperatures. In an experiment using bio-agents, the most effective seed treatment in reducing C. capsici contamination was biomatriconditioning with Trichoderma harzianum (83.7% reduction) followed by biomatriconditioning with T. pseudokoningii (82.3%), Bacillus sp. (79.8%), Gliocladium sp. (79.7%), and Pseudomonas fluorescens (78.3%). However, biopriming was better than biomatriconditioning in improving germination percentage and vigor index. In the field, biopriming with a mixture of Bacillus polymixa BG25 or P. fluorescens PG01 reduced anthracnose disease incidence from 81% in untreated infected seeds down to 9%, and improved plant growth, fruit yield, and seed quality of harvested seeds.
