A Comparative Study on the Relationship between Tree Form and Volume in Stands of Pinus koraiensis and Larix leptolepis 잣나무와 낙엽송림에 있어서 수형과 재적간의 관계 비교 <한국임학회지 74:82-87 Jour. Kor. For. Soc. 74:82-87 1986> Corresponding author kimjh@kangwon.ac.kr
Noticed that large number of the Korean white pine (Pinus koraiensis S. et Z.) has lost typical excurrent tree from by removal of apical shoot in the process of cone harvesting, the investigation and analysis for the species were made on the basis of the relationship among DBH, total height, merchantable height, and merchantable volume, compared with normally grown Japanese larch (Larix leptolepis Gordon). One hundred sample trees for each species were selected in the same aged stands for the study. Results have indicated that the pine has shown abnormal height growth pattern mainly by the disturbance of external artificial force. The pine's forked and/or crooked stems by the reason have led the result of less merchantable volume in the same DBH classes. Consequently, the pine would have undesirable tree form in terms of timber production, unless free from apical shoot disturbances. Considered to the merit of the Korean white pine that can produce timber and pine nuts, management alternatives for the pine stand were suggested to achieve maximum rate of return for the silvicultural investment. For the around 15-year-old Korean white pine plantation, the whole stand may be designated as timber production or pine nut production forest. The height growth should be restrained and forked branches induced as extremely as possible for the stand or trees, so as to maximize cone formation and minimize timber production. We would prevent trees from damage of apical shoot and bring up straight hole as extremely as possible for the stand or trees, so as to maximize high quality timber production and minimize pine nut harvesting.
Key words: tree from, merchantable volume, pine nut production, Pinus koraiensis, Larix leptolepis
대다수의 잣나무가 잣을 수확하는 과정에서 수간 정단부의 인위적인 손상으로 말미암아 전형적인 잣나무 수형을 잃게 되는 점에 착안하여, 정상적으로 생육한 낙엽송과 비교하여 임목 제형질들의 관계를 조사 연구하였다. 동령급의 두 수종을 비교한 결과, 잣나무는 정단부의 절단으로 인하여 정상적인 수고생장을 못하고 있음을 알 수 있으며, 또한 심하게 분간되거나 굴곡된 수간은 이용재적 값을 낮추는 결과를 초래하여 목재생산의 측면에서는 바람직한 수형을 갖지 못하고 있었다. 그러나 잣을 수확할 수 있고 용재를 생산할 수 있는 잣나무의 특성을 감안하여, 조림투자에 대한 회수율을 최대화하기 위한 잣나무 식재림에 대한 경영적 대안을 제시하였다.
