This study aims at revealing the relationship between physiological characteristics and growth by family for open-pollinated progeny stand of Korean white pine in Gapyung site, Korea. Average growth performance of total 25 families for 18 years old progeny stand showed 5.9m in mean height, 8.9cm in mean DBH, 12.0§³ in basal area per hectare and 46.5§© in volume per hectare, respectively. By the analysis result of growth performance for all 25 families, family No. 20 showed the most excellent growth; family No. 10 the middle; and family No. 3 the worst growth. The change of seasonal photosynthesis rate by increasing luminous intensity was the same tendency as the growth pattern of all 25 families and showed      the same results in all four seasons. Tn the seasonal analysis, the photosynthesis rate was  increased as the season has changed from winter to summer. Chlorophyll contents also increased from winter to summer. Especially, family No. 20 which is the best in growth performance has more chlorophyll contents than the others. Family No. 20 was also better than    other families in the weight of assimilation tissue(g), length of needle(cm), width of needle(cm), and number of stoma. However, in water utilization rate, family No. 3 which is the  worst in the growth performance showed the best result that is reverse tendency compared with the photosynthesis rate. The changes of water utilization rate represented to be increased as the season has changed from winter to summer.
Key words: Pinus koraiensis, physiological characteristics, growth, water potential, phtosynthetically active radiation, light-photosynthesis curve, pressure-volume curve
