全尙根 경희대학교 부설 식량자원개발연구소 1988 硏究論文集 Vol.9 No.-

Average height, diameter and seed weight of twenty two mother trees, and height and diameter growth of progeny families from the mother trees were examined, and the variations depending upon family and block for five years (from 5-year-old to 9-year-old seedlings), as well as relationships among surveyed characters were analysed in Korean white pine. The results obtained from the above were as follows; 1. Mean height and diameter of the mother trees were 18.78 ± 0.37m and 28.30 ± 0.89 ㎝respectively, and the coefficients of variation were 9.21% for the height and 14.7% for the diameter. 2. Average seed weight over the whole families was 610.9±11.9㎎, but it varied with mother tree and seed production year. The F-11 mother tree produced the heavest average seed weight of 847.2±45.0㎎ and A-15 showed the lightest average seed weight of 448.3±18.7㎎. 3. The average height and diameter of progeny families from 5-year-old to 9-year-old seedlings, and the coefficients of variation of the two characters were as following table. 표 원문을 참조하세요 4. The height and diameter growth were affected by family and block, and showed the change of exponential curve with the increase in seedling age, and the estimated growth formulas of height and diameter were Y=4.450e^(0.243)x and Y=0.249e^(0.410)x 5. The effect of family on the variance in height and diameter decreased but that of block increased linearlly with the increase in tree age. 6. No. relationships between height and diameter were found in mother trees and progeny seedlings. But relationships between height and diameter in mother trees, progeny seedlings, and among seedling ages, were significant.

全尙根,申萬鏞 慶熙大學校 1985 論文集 Vol.14 No.-

Variation and heritability of leaf length and number of serration were investigated for 3-year-old seedlings from 75 mother tree in Korean white pine (Pinus koraiensis S. et Z.) The range of leaf length was from 2.1㎝ to 12.8㎝ and 7.37±0.18㎝ in average. Number of serration was ranged from 6.7 to 20.7 and the average was 12.91±0.50. Significant differences among families for the above two traits were recognized. Estimates of single tree and family heritability by variance analysis were h^2_I=0.15 and h^2_F=0.21 for leaf length, and h^2_I=0.38 and h^2_F=0.55 for number of serration respectively.

The variations and heritabilities according to the planting regions and the families from open- pollinated trees aged 7 years were investigated in Pinus koraiensis. Experimental forests were established with 18 families in 3 different regions. The growth of height and diameter varied significantly with the families and the planting regions. The family of number 8 showed the best growth in 90.17cm of height and 15.98mm of diameter, and Ka-pyong area showed the highest growth in height and diameter and the highest estimate of heritabdity . Estimates of individual tree and family heritability were h^2_I = 0.44 and h^2_F = 0.83 in tree height and h^2_I = 0.21 and h^2_F = 0.69 in diameter, respectively. Positive coefficients of correlationship between diameter and height were found in 3 different regions.

In the seedling grown under different light internsities for two years at seed bed, length of needle, density of serration, number of stomata and stomatal zone, and number of endodermal call in needle varied with relative light intensity except number of secretory cell. And the leaf characters were influenced by the light intensity in contribution rates from 18.4% to 34.3%. Positive correlation between the growth and weight of seedlings and the leaf characters were recognized. But there were no significant correlations between the growth of seedling and number of serration, and between the weight of seedling and density of stomata and serration.

This study was carried out to estimate effect of slope site as a factor of environments on variance of height and diameter growth by family in half-sib progeny of Korean White Pine. Data were collected from 7-, 12-, and 17-year-old trees by family in the progeny test forest established in Kyung Hee university forest loca-ted at Youngdong-Gun, Chungchongbuk-do province. Average heights and diameters were 59.1±0.6cm(cv=30.4%) and 10.1±0.lmm(cv=25.1%) in 7-year-old, 198.7±1.7cm(cv=23.5%) and 39.2±0.4mm(cv=26.5%) in 12-year-old, and 443.5± 2.6㎝(cv=16.5%) and 81.2±0.6mm(cv=22.1%) in 17- year-old, respectively. No. 20 family showed excellent growth of 79.1±2.8cm and 12.9±0.3mm in 7-year- old, 236.2±6.5cm and 46.7±1.3mm in 12-year-old, and 502.0±9.6cm and 90.4±2.5mm in 17year-old in mean height and diameter. No. 21 family showed worst growth of 46.7±1.7cm and 8.8±0.2mm in 7-year-old, 168.8±4.6cm and 33.8±l..1mm in 17-year-old in mean height and diameter. Height and diameter growth variance was influenced by slope site with family. Family source more affected on variance of height and diameter growth than slope site did. On the whole, growth variances due to slope site decreased and cleared with tree age increase but showed differently in height and diameter. Between slope distance from down to up and height and diameter growth minus correlation was found and varied with family, significant correlation coefficient appeared in only 6 of all 16 families in height growth but only one family in diameter growth on 7-, 12-, and 17-year-old trees.

Variations, heritabilities and genetic gains for height and diameter growth of 14-year-old progenies of 20 Korean white pine(Pinus koraiensis) families were investigated in Youngdong site. Family, Block, and Family×Block interaction were significant sources of variance for height and diameter growth of the progenies. The average height and diameter were 271.5±1.9㎝, 54.8±0.4㎜, respectively. Variance components ratio of family to total variance components in diameter was higher than that in height. Heritability estimates of height growth were higher than those of diameter growth. Estimates of family and individual tree heritability were 0.64, 0.37 in height growth, and 0.55, 0.21 in diameter one, respectively. When the top 10% of individuals or families were selected, the expected genetic gains for tree height and diameter were 37㎝(13.6% of the average height) and 4.7㎜(8.6% of the average diameter) in the mass selection, 24.4㎝(9.0%) and 1.2㎜(2.2%) in the family selection, 27.7㎝(10.2%) and 15.4㎜(28.1) in the within family selection, 52.1㎝(19.2%) and 16.6㎝(30.3%) in the combined selection, respectively.

全尙根 慶熙大學校 1991 論文集 Vol.20 No.-

The variation and heritability for field germination were investigated in Korean white pine. Open pollinated seeds were collected from 131 individual trees grown at 7(A∼G)different stands. The results were as follows: 1. Field germinations ranged from 2.08±0.86%(in D6 family)to 77.13±7.30%(in A7 family)with mean 37.91±0.86%. The high variance of field germination showed with 52.15% of CV value. 2. Family was a significant source of variance(1% level)for the field germination. The effect of family source on the field germination variance was 82.24% in the contribution rate. 3. Field germination was effected by the site of mother tree stand. Average field germination of seeds from trees of stand A showed the lowest value of 21.80±2.23%, however, stand B did the highest value of 38.58±4.71%. The effect of site source on the field germination variance was 6.25% in contribution rate. 4. The broad­sence heritability estimated for fieid germination was h^2=0.825.
