구기자혹응애(Eriophyes kuko KISHIDA)의 침입기에 의하여 구기자나무(Lycium chineens MILL.)외 잎형성된 혹(mite gall)의 생화학적 성질을 구명할 목으로 몇 가지 효소의 활성도, 화학성분의 함량 및 호량 등에 관하여 실험한 바 다음과 같은 결과를 얻었다. Catalase와 peroxidase 활성도는 건전한 잎의 직보다 혹 조직에서 높았으며 혹이 점차로 커짐에 따라 활성도도 높아졌다. 2. 조효소의 phosphorylase 활성도는 큰 혹(matured gall) 조직과 건전한 잎의 조직에 있어서 차이가 없었으나 활성 측정에 미치는 다른 효소의 영향을 고려하면 건전한 잎의 조직이 높은 것 같으며, phosphomonoesterase의 활성도는 건전한 잎의 조직보다 큰 혹 조직이 5배 가까이 높았으며 와 invertase 등의 활성도는 큰 혹 조직이 2배 가까이 높았다. 3. 조단백질 함량은 혹의 발생 형성초기인 작은 혹일때는 정도 건전한 잎의 조직보다 증가하였으나 혹이 점차 커 짐에 따라 감소하는 경향을 나타내었으며, 환원당은 자은 측일 에는 약간 감소하는 경향이었으나 혹이 점차 커짐에 따라 증가하였다. 인과 tannin의 함량도 혹이 점차커짐에 따라 증가하여를 혹이 건전한 잎보다 2배정도 많았다. 4, 호흡에 있어서 는 혹 조직이 건전한 잎보다 높았으나, 는 반대로 건전한 잎이 높았으며, RQ는 혹 조직이 낮았다.

This study was focused on the relationship between horticultural preference and parenting attitude of parents having elementary school students. Because a human’s preference of plant was inhered an image of one’s life. This study carried out to define the variables related to horticultural preference and parenting attitude, for promotion in horticultural activity program of parent. For this study, the data was collected from 193 parents having elementary school child from May to July, 2015 at Seoul, and Jeonju city. The major variables related to parenting attitude were grade of children, dialogue hour with their children, understanding of their children, intimate, number of breakfast, occupation, family income, growing activity. And the relationship between parenting attitude and horticultural preference were marked statistical difference at plant classification into need a supporting stick, foodstuff, life time of plant, individual or community growth, cook and industrial arts or ornamental plants. Especially it was concerned in achievement, rationality, affection of parenting attitude.

Background : This study analyzes changes in DPPH radical scavenging activity, total polyphenol contents, and total flavonoid contents of six different kinds of Kenaf (Hibiscus cannabinus L.) leaves which are identified as herbaceous plants, and are living in the subtropics. The data of changes in polyphenol, flavonoid contents and DPPH radical scavenging activities were analyzed, based on two different lengths of growth period.. Methods and Results : The six different kinds of cultivars ; Jangdae in Korea, and El-1, R, G-1, Ef-1, Ef-2 in the State of Israel were collected on the 43th and 62nd day from when they have planted. The collected cultivars were dried at 70℃, and 80% of methanol concentration was applied to each ground specimen. Extraction was made by immersion and filtering process at room temperature. Samples were classified into two groups, one for cultivars that were collected on the 43th day, and the other for the collection of the 62nd day. We measured the rate of DPPH radical scavenging activity, total polyphenol contents, and total flavonoid contents for every Samples. For the group of the 43th day collection, Jangdae showed the highest rate of radical scavenging activity as well as the highest polyphenol contents, and El-1had the highest flavonoid contents. For the group ofthe 62nd day collection, R demonstrated not only the highest contents of polyphenol and flavonoid, but alsothe highest rate of antioxidant activity. When we compared each cultivar from another regardless its date of collection, R resulted biggest increase in all of functional components. Conclusion : Based on the test results, useful components and antioxidant activity of kenaf leaves increase in proportion to longer growing period. Particularly, the study indicates that R can be utilized as a cosmetic ingredient crop, as the rate of increase in polyphenol and flavonoid contents were highest among the six cultivars.
