“…Although fungal attack causes an increase in mortality, its presence is a factor that can positively influence the germination process, since it leads to deterioration of the coating/integument. It was not measured in this experiment, but have already been observed between Alternaria, Aspergillus fungi and Astragalus utahensis seed (Long et al, 2012;Eldredge et al, 2016) and between corn and Fusarium subglutinans (Rheeder et al, 1990).…”

This study evaluated the presence of integument dormancy in Melanoxylon brauna seeds by testing the influence of nine pre-germination treatments on seed germination compared to a control (no pregermination) treatment. Pre-germination treatments include; immersion in sulfuric acid for 5 min, 10 min, 15 min and 30 min, hot water at 80°C without soaking, hot water at 80°C with soaking for 30 min, 90 min, 24 h, and mechanical scarification. The experiment consisted of a completely randomized design, with four replicates and 25 seeds per experimental unit. Percentage germination, germination speed, number of normal and abnormal seedlings, and mortality rate were evaluated. Seeds began to germinate at four days, and germination varied from 33 to 89%, with the highest percentage found in hot water with or without soaking for 30 min, which not differed statistically from control. Immersion in sulfuric acid for longer than 10 min reduced seed germination and increased mortality rate. We conclude that M. brauna seeds do not undergo seed dormancy, and there is no need to apply pregerminating treatments to its seeds.

“…Treatment with PGPF, particularly of the genus Aspergillus, Alternaria, Trichoderma, Penicillium, Fusarium, Sphaerodes and Phoma has been reported to improve seed germination and seedling vigor in different agronomic and horticultural crops ( Table 2). Scarified seeds inoculated with spores from Aspergillus and Alternaria had significant increases in germination of Utah milkvetch (Astragalus utahensis) in vitro, and in greenhouse and fall-seeded plots near Fountain Green and Nephi [55]. The Aspergillus-treated seeds performed out seeds inoculated with Alternaria.…”

Plant growth-promoting fungi (PGPF) constitute diverse genera of nonpathogenic fungi that provide a variety of benefits to their host plants. PGPF show an effective role in sustainable agriculture. Meeting increasing demand for crop production without damage to the environment is the biggest challenge nowadays. The use of PGPF has been recognized as an environmentally friendly way of increasing crop production. These fungi have proven to increase crop yields by improving germination, seedling vigor, plant growth, root morphogenesis, photosynthesis, and flowering through either a direct or indirect mechanism. The mechanisms of PGPF involve solubilizing and mineralizing nutrients for easy uptake by plants, regulating hormonal balance, producing volatile organic compounds and microbial enzyme, suppressing plant pathogens and ameliorating abiotic stresses. Successful colonization is an intrinsic factor for most PGPF to exert their beneficial effects on plants. A certain level of specificity exists in the interactions between plant species and PGPF for root colonization and growth promoting effects. There is a gap between the number of reported efficacious PGPF and the number of PGPF as biofertilizer. Efforts should be strengthened to improve the efficacy and commercialization of PGPF. Hence, this chapter summarizes valuable information regarding the application and mechanisms of PGPF in sustainable agriculture.
