在日本,肉桂Cinnamomum sieboldii 以前栽培于和歌山、高知、鹿儿岛等温暖地带,据说在战前的最盛期,年产量达100吨左右,但现在产量极少。即温度越高,到发芽的时间越短。肉桂的果肉中似乎存在抑制发芽的物质,除去果肉并呈绿色的种子,发芽率较高。种子采收后不要马上播,必须到翌年春天再播。大量贮藏种子时,其贮藏法以贮 In Japan, cinnamon Cinnamomum sieboldii was previously cultivated in warm areas such as Wakayama, Kochi, and Kagoshima. It is said that at the pre-war period, the annual output reached about 100 tons, but production is now very small. That is, the higher the temperature, the shorter the time to germination. In the pulp of cinnamon, there appears to be a substance that inhibits germination. The removal of pulp and the appearance of green seeds has a higher germination rate. Do not sow seeds immediately after they have been harvested. They must be broadcast again in the spring of the following year. When large quantities of seeds are stored, their storage methods are stored
