Studies on Analyzing Meteorological Elements Related with Yield of Tricholoma matsutake (S. Ito et Imai) Singer.

This study was carried out to obtain basic information elucidating relationship meteorological elements and yield of Tricholoma matsutake. The yields of pine mushroom in seven areas including Yangyang-gun more than 30,000 kg. Pine mushrooms were generally distributed in the red pine (Pinus densiflora) forests of East-Coast Region, Sobaek and Taebaek-Mountainous Regions, Yeongnam-Central Region and North-Central Region of Korea. Yields of pine mushroom were significant correlation with precipitation during April-October in last years, average minima temperature during July-September, rainy days during Aug. 21-Sep. 10 and precipitation during Sep. 11-30, etc. Air and soil temperature during pine mushroom yield period were 15-25 and , respectively. The first collection date of pine mushroom could be predicted by measuring the soil temperature at 5 cm depth.
