Abstract
According to Yoshihisa Kuroki's report that the total amount of carotenoid was more in the susceptible to pine bark beetle, than in the resistant ones, carotenoids were extracted from needle leaves of one year old seedlings of Pinus thunbergii, Pinus desiflora, Pinus rigida, Pinus koraiensis, Pinus rigitaeda and Pinus taeda which are all important pines in Korea, to find their resistant ratio to the insect. The carotenoids were analyzed and compared using the spectra of them by spectrophotometer. The results were as follows: 1. The visible absorption spectra of carotenoids in those pine trees were proved to be very similar. 2. The total amount of carotenoids in needles differed with the tree species and the contents were arranged in decreasing order P. koraiensis>P. rigida>P. thunbergii>P. rigitaeda>P. taeda, it seemed that there was corelation between the cartenoid content and the extent of harm caused by the pine bark beetles except P. koraiensis. 3. But carotenoids were contained in Robinia pseudoacacia, Castanea crenata, Chamaecyparis obtusa and Cedrus deodra leaves too. 4. The total amounts of carotenoids in these pines of 9 species were arranged in decreasing order Robinia pseudoacacia>Pinus koraiensis>Pinus rigida>Pinus thunbergii>Castanea crenata>Pinus rigitaeda>Pinus taeda>Chamaecyparis obtusa>Cedrus deodara. Therefore, it was proved that there was no correlation between carotenoid cotent and extent of resistance to the insect. 5. In the thin-layer chromatography of these carotenoids, 13 kinds of components in P. densiftora, P. koraiensis and P. rigida and 12 kinds of spots in other pines, were detected respectively, under ultra-violet fluorescent lamp
소나무좀에 감수성(感受性)인 소나무류(類) 잎에는 carotenoid의 함량(含量)이 많고 저항성(抵抗性)인 소나무류(類) 잎에는 그 함량(含量)이 적다는 흑목등(黑木等)의 보고(報告)에 따라 소나무 곰슬 리기다소나무 잣나무 리기테-다소나무 태-다소나무의 소나무좀에 대한 저항성정도(抵抗性程度)를 밝히기 위하여 이들 소나무류(類)의 일년생(一年生) 묘목(苗木)의 침엽(針葉)으로부터 Carotenoid를 추출분석(抽出分析)하여 얻어진 결과(結果)를 다음과 같이 요약(要約)할 수 있다. 이들 소나무류(類)에 함유(含有)되어 있는 carotenoid의 가시부(可視部) 흡수(吸收)spectrum은 매우 비슷하였다. 이들 일정침엽량(一定針葉量)에 함유(含有)된 carotenoid의 량(量)은 잣나무>리기다소나무>곰솔>리기테-다소나무>테-다소나무의 순(順)이였다. Carotenoid는 아가시아 밤나무 편백 희마라야시-다 잎에도 함유(含有)되어 있었고 이들 9수종(樹種)의 carotenoid의 총함량비교(總含量比較)는 아가시아>리기다소나무>곰솔>밤나무>리기테-다소나무>테-다소나무>편백>희마라야시-다 순(順)으로 나타나 이것은 carotenoid의 함량(含量)과 소나무좀에 대한 저항성정도(抵抗性程度)를 직결(直結)시켜서 설명(說明)하는데에는 난점(難點)이 있다고 생각되었다. carotenoid의 thin layer chromatography에 의하면 소나무 잣나무 리기다소나무에서는 13개(個)의 spot기외(其外)의 소나무류(類)에서는 12개(個)의 spot가 자외선형광등(紫外線螢光燈)
