The pollen morphology of nine species and one variety of Korean Salix was investigated by means of light and scanning electron microscopy. Pollen grains are tricolpate or tricolporate varying from subprolate or prolate. Based on aperture and sculpture patterns, the pollen morphology of the investigated Korean Salix appeared to exhibit three different types.

This study was on investigation of cuttings after 24 hrs. treatment of IBA 20ppm solution of 10 stage pH level, in order to promote rooting of cuttings of Thuja occidentalis L. The results are summarized as follows; 1. Different pH values of auxin solution for rooting promotion of cuttings were significantly influential in rooting. 2. In the cutting collected from 8-years old Thuja occidentalis L., very good results were obtained from the pH 6.0-6.5 level of 20 ppm IBA solution, good results from the pH 5.5 and pH 7 level, and poor results from the pH level near strong acid. 3. In the development of rooting system, average rooting numbers, rooted lengths and rooted weights were developed in proportion to the rooting ratio. 4. Rooting portions were observed with the naked eye to develop in formed callus and epidermis tissue, in epidermis tissue above formed callus, and in epidermis tissue above portion without formed callus. Color of callus portion was reddish-brown.

The response of callus formation and the growth rates of sectioned Gingko hypocotyl to upper, middle and lower section cultured with several methods on white's basic medium are summarised as follow; 1. Organ culture sectioned hypocotyl to upper, middle and lower sections is most flourished at the lower section and followed middle and upper. 2. Sectioned hypocotyl which had attached same ranks of endosperm in embryo are better developed than isolated one. 3. When the upper section of sectioned hypocotyl transfer to lower endosperm and lower one to upper none accelerated effect are given on the endosperm. 4. Shoot without root have developed on lower hypocotyl section attached endosperm.

새마을 所得增進을 위한 리기다 소나무 間伐材의 松脂採取와 經濟性分析
洪性玉,위흡,高大植 全北大學校 1981 論文集 Vol.23 No.-
리기다소나무는 우리나라의 방대한 面積에 植栽되어 最近 多量 生産되고 있으며 앞으로도 그의 生産이 繼續될 趨勢에 있으나 木材的 特性 때문에 利用範圍가 극히 制限되어 있는 實情이다. 이러한 리기다소나무의 間伐材에 대하여 그의 活用方案을 媒索하고자 本 硏究에서는 松脂를 효율적으로 採取할 수 있는 方法 및 그의 經濟性 分析, 組成分의 質的 分析, pulp用材로 利用하기 爲한 處理方法 등에 대하여 硏究하였던 바 그 結果는 다음과 같이 要約될 수 있다. 1. 伐採하기 前 間伐材에서 松脂를 採取할 수 있는 時期는 5月부터 10月까지이며 地域에 따라서 또는 海拔高에 따라서 약간의 差異는 있으나 松脂流出의 最盛期는 7月中임을 알 수 있었다. 2. 松脂는 樹幹의 胸高 部位의 南向에서 採取하는 것이 量的으로 가장 有利함을 알 수 있었다. 3. 採脂溝數를 3개로 하는 것이 1本 1回 實施할 경우 가장 理想的이었으므로 斜溝式採取方法 (Japanese saw method)에 있어서 切傷距離를 약간 크게 하는 것이 좋지 않을까 생각된다. 4. 採脂量은 樹幹의 크기에 따라 크게 影響되며 小徑木에 있어서 Mason方法에 의한 이들 關係를 回歸式으로 나타내면 Y^=1099.24X-3197.60이었다 (단 X=DBH, Y^=採脂量) 5. 松脂의 流出速度는 切傷後 9時間 以內에 總流出量의 約 65% 程度가 流出되었다. 6. 리기다소나무의 松脂에 含有된 monoterpene의 組成은 含量別로 볼 때 α-pinene, β-pinene, β-phellandrene, camphene, Δ-3-carene順으로 되어 있으며 이들중 특히 α-pinene의 含量으로 볼 때에 時期別 樹幹部位別 및 方位別로 큰 差異 없이 대체로 40% 以上이었으므로 리기다소나무의 松脂의 質은 良質의 것임이 判明되었다. 7. 리기다소나무에서 松脂를 採取하므로서 樹幹內에 松脂含量이 減少되거나 材質의 變化는 없었으며 間伐材의 松脂量 減少는 3個月 내지 6個月 동안 野積하므로서 成就할 수 있음을 究明하였다. 8. 리기다소나무의 松脂採取는 大徑木일 때에는 收益性이 대단히 크나 小徑木에서의 採脂는 收益性이 없었다. 다만 遊體勞動力이나 年少者에 의한다면 農山材의 所得增大에 寄與하리라 생각된다. Our country has planted Pinus rigida seedlings in a large scale every year for the last three decades and now they are old enough to be cut for thinning. Actually the thinned timbers are massproduced recently, however, the market value is very low and the utilization of the timber is limited because of its high level of resin content in wood and its twisted wood grains. As an effective utilization of this species the present study investigated possible ways of collection of pine resin (naval store) from the trees before they are cut for thinning, analysed qualitative properties of resin and economical profitability from the resin collection and suggested a pretreatment method to decrease resin content in wood to be used for pulping. The obtained results are as follows: 1) It was found that resin can be collected from May to October and the maximum yield of resin can be obtained in July, though it varied a little with location and elevation. 2) Tapping on the stem southward in breast height resulted in the highest yield of resin. 3) The optimum number of streaks for tapping is thought to be three in every 20㎝ stem length. 4) The resin yield was considerable affected by the size of stem diameter and a regression equation between DBH(X) and resin exudation amount(Y) by Mason's method was calculated as follows; Y=1099.24 X-3197.60. 5) About 65% of total amount of resin yield were exuded within 9 hours after the start of tapping. 6) Components of monoterpene in oleoresin of this species were α-pinene, β-pinene, β-phellandrene, camphene and Δ-3-carene in order from the most to the least. Quality of oleoresin was found to be good in view of its high content of α-pinene (more than 40%) regardless of season, stem part or orientation. 7) Resin content in wood was not decreased, nor wood density changed after resin collection from the stem. A method of decreasing resin in wood was found to pile the thinned timbers in the field for three to six months before they are used for pulping. 8) A good profitability was shown when resin was collected from the trees having large stem but it was not when collected from small stemmed trees. However, if resin is collected by young idle labour in mountain it may be profitable to collect resin even from the small size trees.

In order to the basic researches of alcohol production with using wood meals of Pinus rigida Miller and Alnus japonica Gordon, chemical compositions were analyzed and conditions of acid hydrolysis were established. The results were summarized as follows. 1 . In acid hydrolysis by wood materials, the high yields of reducing sugars were shown from 1.0% to 2.0% of hydrochloric acid and sulfuric acid. The highest yield was Produced 23.4% at wood meals of Alnus japonica. 2. The effect of raising the hydrolysis was good at 1.5kg/cm2, 30 times(acid/wood meal), and 45 min. in treating hydrochloric acid and 30 min. sulfuric acid. 3. The pretreatment were effective for 50% of sulfuric acid and optimal temperature of heat treatment were at 190℃. 4 . Sugar composition of acid hydroiyzates were chiefly assayed glucose and arabinose.
