FFECT OF RNA RELATED COMPOUNDS ON FRUCTIFICATION OF TRICHOLOMA MATSUTAKE
RNA复合物对松茸子实体的作用

Ribonucleic acid and 5-nucleotide were tested for fructification of Tricholoma matsutake in the field. Water solutions of RNAs were directly added to the mycelial colony of pine forest floor prior to fructification stage. Content of glucosamine, ergosterol and phospholipid of mycorrhizal fine roots were measured for estimation of mycelial status during growth and fructification stages. Phospholipid content was rapidly increased after RNAs addition. RNA solutions affected to make higher level of the mycelial components than control. As the final results, yield and number of T. matsutake fruit body were dramatically increased by the addition of RNAs during fructification period. This procedure was repeatedly done on the same plots three times in every fructification season, and resulted to all positive effect for RNAs supplement.
