Effects of Some Meteorological Factors on Number of Cone Formation in Pinus koraiensis <Jour. Kor. For. Soc. 57:45-51 1982> Senior author Sang-Keun Chon
 
The environmental influence on cone crop of Pinus koraiensis. has been studied by means of correlation and regression analysis of number of 1-year-old cone and meterological data. A positive effect on cone crop is brought about by low air temperature during the year of flower bud differentiation (possibly June in Korea) and much sunshine duration for the year and the winter before flower bud differentiation. The weather of June before flower bud differentiation is very important for cone production.
Key words: Pinus koraiensis, cone crop, meterological factors
