中国におけるコケ類の利用 : 2. 五倍子の生産に欠くことのできないコケ類

抄録

Galinuts, an important source of tannic acid, are produced on leaves of Rhus javanica which have been parasitized by the aphid Schlechtendalia sp. The production of gallnuts is associated with the growth of mosses, especially Mnium (s. lat.) species, because gall aphids over-winter in cocoons that they make on the mosses. The industrial management of Mnium plants for increasing gallnut production is well developed in China, where gall-making aphids are artificially raised on Mnium plants cultivated indoors under controlled conditions.
