Abstract:

In Chuxiong Prefecture, Baoshan City and Diqing Prefecture of Southwest China′s Yunnan Province, three study sites were selected and designated to observe and monitor the fruiting pattern of Tricholoma matsutake, and at the same time record the associated meteorological factors such as temperature, precipitation, humidity and soil temperature by installing wireless Vantage Pro 2 weather stations. It was found that the starting dates and peaks of fruiting varied across the study sites. In Yeri Village of Diqing Prefecture, the fruiting started earlier and showed a single condensed peak. In Haitang Village of Baoshan City and Qingcaitang village of Chuxiong Prefecture, however, the fruiting was scattered over a longer period of time and presented 3 fruiting peaks. The growth function (the pileus diameter, stipe diameter and height) of the fruiting bodies followed nonlinear regression models respectively. By analyzing the differences of the meteorological factors in three study sites and the effects of meteorological factors on matsutake fruiting and growth, it was found that high temperatures shortened the survival duration of the fruiting bodies whereas in contrast, the opposite effect was found for humidity. Furthermore, soil temperature may be the most important factor for fruiting initiation.
