산채시험장에서 선정한 80종의 자생 산채류 중에서 54종이 보고 되어 있으며 식물종류별로는 더덕에 관한 보고가 61편으로 제일 많았고 17종은 보고 되지 않았다. 분야별 논문편수는 화학분석 분야가 123편으로 제일 많았고 생태를 비롯한 5분야는 미비하였다. 고려엉겅퀴 및 부지깽이는 새로운 에너지원으로서 개발가치가 높을 것으로 사료되며 잔대 및 화살나무는 비타민 C의 함량이 높았다. 잔대 및 산마늘, 개미취, 갈퀴덩굴, 둥글레 등에서 항암물질 추출에 관한 연구가 행해지고 있고 자생향신료 개발을 위한 배초향 및 쥐오줌풀과 같은 식물의 이용가능성이 증대되고 있다. 부가 가치 창출을 위한 가공 및 기능성에 관한 연구가 필요한 것으로 사료된다.

Ginseng has been used as a medicinal herb in the world for more than two thousand years. Inspection of the quality of ginseng was made since many hundred years ago. Ginseng quality has been graded by several methodes, based on saponin contents, number of ginsenosides, shape of root and tissue elaborateness. In present. ginseng products are usually evaluated by saponin contents and number of ginsenosides. On the other hand, fresh and manufactured ginseng roots such as red. white and semi-red ginseng, Taegeuk Sam, are mostly graded by root shape such as root development and skin (epidermis) color, and tissue elaborateness. which is a conventional grading method. However, the root shape grading method has a risk of overlooking real medicinal properties of ginseng. So. both the medicinal ingredients and the conventional grading method should be considered for the proper evaluation of ginseng quality. Therefore, for the establishment of better method in evaluating ginseng quality, the relationships of root shape and useful components are required to be studied.

Rice Quality is considered to the five catagories ; the nutritional value: the characteristics of cooking. eating and processing: grain size, shape and appearance : milling yields: and storage characteristics. Because most rice is processed and consumed in whole-kernel form. the cooking and eating quality is of important and the physical properties of the intact kernel such as size, shape and general appearance are of particular significance in determining marketing quality. Eating Quality which can be directly evaluated by consumer's panel test is so complicate and variable, and thus the objective and simplified method of evaluation is required of using appropriate instruments. Even though many researches have been done to evaluate the eating quality in various aspects such as the texture of cooked rice kernels, amylogram analysis of rice powder, amylose content. gelatinization temperature. moisture absorption of rice kernel, and cooking characteristics, none of them is satisfied for the evaluation of eating quality. The improving eating quality should be also considered to many cultural factors. such as varieties, climatic and soil conditions, cultural method, handling after harvest. milling and storage conditions. In Korea, many researches in grain size. shape and appearance, and eating quality have been done with the varietal improvement mainly by rice breeders, but no effective method of evaluation was established. A few research have been done in the relationship between rice quality and cultural factors. In the future, research in rice quality should emphasize to establish the standard evaluation method in the physicochemical properties of rice kernels for application of varietal selection. and to develop cultural practices for the preserving quality characteristics of the varieties.

Since 1970, herbicides have been widely used in the crop production, especially in paddy field in Korea. In 1978, both preemergence and postemergence type herbicides are applied in the approximately 70% of total paddy field and 15% of upland to control weeds. Most herbicides control annual weeds effectively, but perennials have been problems in the paddy field. Under upland conditions, effectiveness of herbicides varies depending on many environmental conditions (soil moisture, soil physical properties, temperature, etc.) as well as uniform application of appropriate amounts of herbicides. In Korea, many research works have been concentrated on the screening of new herbicides in terms of herbicide effectiveness and yield or phytotoxicity of crops, and especially on the paddy field. However, physiological aspects of herbicidal action in plant and interaction of herbicides with the environments have not been studied approximately. Therefore, researches on the uptake of herbicides and the influence of herbicides on the physiological phenomena such as photosynthesis, respiration, nutrient uptake etc., to control troublesome perennial weeds in the paddy field are needed in future. Also some researches are needed to improve effectiveness of herbicirdes under upland conditions.
