    FFECT OF RNA RELATED COMPOUNDS ON FRUCTIFICATION OF TRICHOLOMA MATSUTAKE

    Abstract: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.

    摘 要:施用核糖核酸和5'-核苷酸試驗,其對生長于林間的松茸子實體的活化作用.在形成子實體之前將RNA關(guān)聯(lián)物的水溶液直接灑入帶有菌絲群落的松樹林地表層.為了估計處于生長和形成子實體時期菌絲的狀況對高菌根含量根中核苷、麥角固醇和磷脂的含量進(jìn)行分析.與對照相比,RNA關(guān)聯(lián)物的水溶液對提高核苷、麥角固醇和磷脂含量有作用,施用RNA關(guān)聯(lián)物后9天磷脂含量迅速增加,RNA關(guān)聯(lián)物有助于形成密集的菌絲群落.試驗最后結(jié)果表明在形成子實體的兩周時間內(nèi)關(guān)聯(lián)物使松茸子實體的產(chǎn)量和數(shù)量顯著增加.
