Monoterpenes, phenolic substances, growth substances and total nitrogen from normal needles and infested needles attacked by Thecodiplosis japonensis were compared for Pinus densiflora, Pinus thunbergii and Pinus rigida. The results obtained in this study were as follows: 1. Major monoterpene components in P. densiflora needles were β-phellandrene, α-pinene and those in P. rigida needles were β-pinene and α-pinene. In P. rigida resistant to this insect, infested needles showed higher α-pinene, β-pinene and myrcene but lower camphene, limonene and β-phellandrene than normal needles. 2. Orcinol, catechol ferulic acid, salicylic acid and five unknowns were detected in P. rigida needles whereas orcinol, catechol, ferulic acid and four unknowns in P. densiflora needles. 3. Tryptophan, a precursor of IAA, was detected in larvae and also in gall tissues of both P. densiflora and P. thunbergii needles. This fact shows that growth substances may involve in gall formation by Thecodiplosis japonensis. 4. Total nitrogen contents per unit needle weight were neither significantly different between P. densiflora and P. rigida, nor between normal and infested needles.

Age-age correlation for height growth of open-pollinated progenies of pinus koraiensis in relation to their cone and seed characteristics

한상억(Sang Urk Han),이재선(Jae Seon Yi) 한국육종학회 1996 한국육종학회지 Vol.28 No.1

Korean white pine(Pinus koraiensis S. et Z.) is one of the important timber species as well as a pine nut producer in Korea. This study was carried out to obtain genetic information including genetic parameters and correlation coefficients. Open-pollinated cones and seeds from 50 plus trees were examined; seedling height was measured at ages 1 to 4 in the nursery; and tree height was measured at ages 5 to 10 in three plantations. The negative correlation was found between the number of seeds per cone and the other seed characteristics, and between the number of cones and all the other characteristics except the number of seeds per cone and cone weight. Seed weight showed highly positive correlation with other seed characteristics, e. g., length, width, and thickness, and some cone characteristics like diameter and weight. The seedling height in the nursery showed highly positive correlation with cone diameter and weight and seed length, weight, width, and thickness. The height in the test plantations showed negative correlation with the number of cones and the number of seeds per cone, but highly positive correlation with seed length, thickness, and weight. The height in the test plantations showed low correlation with the 1st-year height, but highly positive one with the 2nd- to 4th-year height in the nursery. The genetic correlation coefficient was 0.8364~1.0000; and the phenotypic correlation coefficient was 0.4495~0.8935.

This study was conducted in an attempt to quantify some traits that may be involved in the reproductive process of Pinus thunbergii. During the past 6 years (1995-2000), we surveyed flowering patterns of 60 P. thunbergii clones in a seed orchard which was established in Anmyon-do, 1979. From this survey, we estimated clonal contributions of male and female flowers and sexual asymmetry. Among 60 clones, 18 clones (30%) accounted for 0.37 (1999)-0.46 (1995) of clonal contribution in female flowers and 0.44 (1999)-0.57 (1995) of clonal contribution in male flowers. As compared with the previous reports in other pine species, more clones made contributions to reproductive process in P. thunbergh seed orchard. The relative effective population numbers for females (v_♀) varied from 0.59 (1995) to 0.91 (1999) and those for males (v_♀) were between 0.56 (1995) and 0.83 (1998) at gamete level. This showed that the female gametes effectively contribute to the reproductive process more than did the male gametes. The relative effective population numbers at clonal level (v_♀) were in the range of 0.72 (1995) and 0.93 (1999). More than 73% of the total clones showed values of 0.4-0.6 (0.5±0.1) in maleness index. The values averaged over all the clones were temporally variable with the range of 73% in 1996 and 100% in 2000. The degree of sexual asymmetry (A_s) ranged from 0.09 to 0.26. These values were relatively low when compared with those of other trees, suggesting that P. thunbergii seed orchard remains a high level of homogeneity in the number of male and female. All of the various types of effective population numbers were positively correlated with each other while they were negatively correlated with the degree of sexual asymmetry.

Open-pollinated progeny test was established with 58 families of Pinus densiflora plus trees. Heights of 1,2,5,6,8,11,13, and 14 years after planting were measured and analyzed statistically. Heritability was 0.72 at age 1 but gradually decreased to 0.15 at age 14. Genetic and phenotypic correlation based on the log of the ratio of the two ages (LAR) was expressed as simple regression with statistical significance (r²=0.8617, 0.8573). Genetic age-age correlation was bit lower than phenotypic age-age correlation. When the mature age of P. densiflora was assumed as 30 years best efficient selection age was 11 years after planting with efficiency (E) of 1.23.

Korean white pine(Pinus koraiensis S.et Z.) is one of the important silvicultural species due to its quality timber in addition to edible pine - nut production. Selective breeding method is under progress to improve growth and nut production for this species. This study was carried out to obtain genetic information necessary for establishing advanced generation seed orchard, such as genetic parameters and efficiency of early selection. Open - pollinated cones were collected from 50 plus trees. In the spring of 1986, test plantations were established at 3 different sites with 4 - year - old seedlings. Seedling height was measured from age 5 to 10 in plantations. Genetic and phenotypic correlations based on the log of the ratio of two ages (LAK) were expressed as simple regression with statistical significance(r²=0.7862 and 0.8256, respectively). If 20 years is presumed to mature, the most efficient age for early selection is 3 years after planting with efficiency of 1.96.

송정호,박문한,한상억,이위영,박완근,이재선,Song, Jeong-Ho,Park, Mun-Han,Han, Sang-Urk,Lee, Wi-Young,Park, Wan-Geun,Yi, Jae-Seon 한국산림과학회 2001 한국산림과학회지 Vol.90 No.4

굴참나무 동아의 형태적 변이를 연구하기 위하여 위도, 경도, 해발고 및 지리적 특성을 고려하여 16개 천연집단을 선발하였다. 각 집단별로 30개체를 대상으로 개체목당 수관 1/3 하단부에서 정아와 측아를 30개씩 고르게 채집하여 정아와 측아의 길이 및 폭에 대한 변이를 조사한 결과는 다음과 같다. 1. 정아길이, 정아폭, 측아길이 및 측아폭은 각각 6.9~11.3cm, 3.0~3.7cm, 6.1~8.9cm 및 2.5~3.1cm로 나타났으며, 모든 특성에서 약 20% 내외의 변이폭을 보였다. 2. 동아특성에 대한 변이는 집단간 및 집단내의 개체간에 고도의 유의적인 차이를 보였으며 특히, 분산기여도는 집단간보다 집단내의 개체간에 큰 것으로 나타났다. 3. 상관분석한 결과 정아길이는 측아걸이 및 폭과, 측아폭은 정아폭 및 측아길이와 정의 상관을 나타내었으며, 또한 지리적 변이에 있어 위도는 정아폭과, 경도는 정아길이 및 측아길이와 정의 상관을 나타내었다. 4. 군집분석한 결과는 거리지수 3.4에서 2개의 그룹 즉, I그룹(Pop. 8)과 II그룹(Pop. 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16)으로 나뉘었으며, 거리지수 1.5에서는 II그룹이 다시 Pop. 1, 2, 7, 9, 및 11의 군집(II-1그룹)과 Pop. 3, 4, 5, 6, 10, 12, 13, 14, 15 및 16의 군집(II-2그룹)으로 나뉘어 거리지수 1.2 이상에서 총 III그룹으로 분리되었다. For the study of morphological variation in winter buds of Q. variabilis $B_L$. natural populations in Korea, 16 populations were selected through the country in consideration of latitude, longitude, altitude, and geographical characters. Thirty trees were randomly selected from each population and 30 terminal and 30 lateral buds were sampled below 1/3 crown length of each tree. Four morphological characters including length and width of terminal and lateral buds were measured. 1. Length and width of terminal and lateral buds were in the ranges 6.9~11.3cm, 3.0~3.7cm, 6.1~8.9cm, and 2.5~3.1cm, respectively. The coefficient of variation were in about 20% in all the characters investigated. 2. All the characters were significantly different among populations as well as among individuals within populations. The degree of contribution of variance among individuals within populations was higher than that among populations. 3. Length of terminal bud showed positive correlation with length and width of lateral bud; and width of lateral bud with width of terminal bud and length of lateral bud. Also, positive correlations were observed between longitude and width of terminal bud, between latitude and length of terminal and lateral bud. 4. Cluster analysis using complete linkage method for winter bud characters showed two groups to Euclidean distance 3.4. They were group I of population 8 and group II of populations 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, and 16. However, group II was divided into two at Euclidean distance 1.5 that are a group including populations 1, 2, 7, 9, and 11(groupII-1) and the other group including populations 3, 4, 5, 6, 10, 12, 13, 14, 15, and 16(groupII-2).
