Abstract
|
|
|
|
The effects of medium, incubation temperature, incubation period, pH of medium and CO₂ ondition during mycelial growth were investigated to study the factors associated with the formation of oidia in Flammulina velutipes. Oidia formation was increased when mycelial growth was poor, while oidia formation was inhibited in optimum condition of mycelial growth. Mating type of oidia was investigated to examine the effect of oidia formation on dikaryotic strain. Di-mon matings between oidia strains and original dikaryotic strain were carried out. Monokaryotic strains derived from oidia showed only one genotype. Seventy percent among Di-mon mating strains showed slow mycelial growth and low yield of fruit-body, but others showed similar or high mycelial growth and yields in comparision with original dikaryon strain. One strain from di-mon mating demonstrated some differences in isozyme band pattern.
