ABSTRACT
This study was conducted to reveal the effect of some meterological factors on the weight of cone and seed per cone in Korean white pine (Pinus koraiensis SIEB. et ZUCC.). The weight of cone and seed per cone for 7 years from 1992 to 1998 on 45(1992) year-old trees and some meterological factors for 9 years from 1990 to 1998 were surveyed in Hongcheon-Gun region, Gangweon-Do. Simple correlations and multiple regression between weight of cone and seed per cone and some meterological factors were analyzed. The results obtained from the above experiments were as follows: 1. Positive correlations were found between weight of cone and monthly mean temperature of February in flower bud differentiation year. number of annual hoarfrost days of the cone production year monthly mean temperature of may in the cone production year, as July respectively. There were negative correlations between weight of cone and monthly mean temperature of august in the flowering year, wind speed of April in the flower bud differentiation year, number of clear days of december in the flowering year, number of annual cloudy days of the flowering year, number of precipitation days of june in the flowering year, number of annual precipitation days of the flowering year, number of annual cloudy days of March in the cone production year. number of annual cloudy days from march to October in the flowering year as well as number of precipitation from march to october in the flowering year. 2. Positive correlation between weight of seed per cone and number of hours with sunshine duration of June in the flowering year, the percentage of sunshine duration of June in the flowering year, number of clear days of June in the flowering year. monthly mean temperature of may in the cone production year. as well as monthly mean temperature of July in the cone production year were found. Negative correlations were recognized between weight of seed per cone and monthly mean temperature of January in the flowering year, monthly mean temperature of august in the flowering year, wind speed of april in the flower bud differentiation year, number of annual cloudy days of the flowering year, number of precipitation days of June in the flowering year, number of annual cloudy days from March to October in the flowering year as well as number of precipitation from march to October in the flowering year.

강원도 홍천국 북방면 북방리에 있는 45년생(조사착수 당시) 잣나무 인공식재지에서 1992년부터 1998년까지 7개년간의 구과무게 및 구과당종자 무게와 1990년부터 1998까지 9개년간 이 지방의 기상인자를 조사하여 이들 간의 관계를 조사하였다. 화아분화년 2월과 결과년 5, 7월의 기온이 높고, 개화년 8월 기온이 낮으면 구과무게가 무거우며, 구과당 종자무게는 개화년 1월, 8월의 기온이 낮고 결과년 7월 기온이 높으면 무겁게 나타났다. 개화년 6월의 일조시간이 많으면 구과당 종자무게가 무겁고, 개화년 6월 일조율이 높고 결과년 9월이 낮으면 무게가 가벼움을 알 수 있었다. 화아분화년 4월의 월평균풍속이 강하면 구과무게 및 구과당 종자무게는 각기 적음을 알 수 있었다. 개화년 12월의 맑은날수가 많고, 3월과 년간 총 흐린날수, 3월부터 10까지의 총 흐린날수가 적으면, 구과무게가 무거우며, 개화년 6월의 맑은날수가 많고 년간 총 흐린날수와 화아분화후 11월에서 수분전 5월까지의 총 흐린날수가 적으면 구과당종자 무게가 무겁고 개화년 12월 맑은날수가 많으면 가벼움을 알 수 있었다. 개화년의 6월과 년간 총 강수인수, 3월부터 10월의 강수일수가 많으면 구과무게는 적고, 개화년 6월의 강수일수와 결과년의 총 서리일수가 적으면 구과당 종자뚜게도 적음을 알 수 있었다.
