<論文・報告>シイタケ（Lentinus edodes）の微細構造

Abstract

Ultrastructure of stalk and cap in Lentinus edodes were observed under a light microscope, and scanning and transmission electron microscopes. The stalk was composed of highly oriented hyphae having a diameter of 2 to 7 micron meters. Vacuole was well developed in almost all of hyphae. The cap was composed of hyphae that were not highly oriented. The gills were also composed of hyphae oriented perpendicular to the surface of gills. Cell organelle such as nucleus, mitochondrion and rough-endoplasmic reticulum, were filled in the hyphae.

シイタケ（Lentinusedodes）の柄と傘の微細構造を光学顕微鏡、走査電子顕微鏡、透過電子顕微鏡で観察した。柄では直径は2〜7μmの菌糸が柄の長軸方向に配向していた。ほとんどの菌糸では、液胞が発達していた。傘では柄と同様な菌糸が観察されたが、柄ほど配向はよくなかった。ひだでは、菌糸はひだ表面に対し垂直に配向しており、細胞は液胞の発達が見られず、核やミトコンドリア、リボソーム、粗面小胞体などの細胞小器官が観察された。
