  Determination of climate predictor variables effecting on annual cone harvest and seed yield of Korean pine (Pinus koraiensis Siebold & Zucc.) seed orchards
  Author(s): Kim YY*, Ku JJ, Kim JH, Lim HI and Han J
  
  Background: Korean pine (Pinus koraiensis Siebold & Zucc.) is a native pine species of Korea. The relationship between climate conditions and seed production of Korean pine has not been clearly revealed yet compared to other pines. This study was conducted to identify climate variables that are significantly related to cone and seed production in three seed orchards of Korean pine. Methods: Regression model for cone harvest and seed yield was built using climate elements such as monthly mean temperature, monthly total precipitation, and monthly hours of sunshine as predictor variables. Results and Discussion: The seed yield model had higher predictive precision than the cone harvest. For the seed yield model, seven climate variables were associated with seven major phenological periods in the three-year reprodu.. View More»
