Phytochemical investigation of the sesame dregs of Sesamum indicum was conducted by open column and prep-HPLC chromatography. Two phytosterols (1 and 2) and two lignans (3 and 4) were isolated from the MeOH extracts of sesame dregs, and identified as ${\beta}$-sitosterol (1), daucosterol (2), sesamin (3), and sesamolin (4) by spectral analysis. Although these compounds were already isolated from sesame, it is important that they were still main phytochemical components in the sesame dregs.

An investigation of the freshwater algal flora of Nakdong river estuary, Jinyang Lake and Danjang stream was carried out from May to November in 1993. This paper deals with a total 16 taxa belonging to 5 genera which are recorded for the first time in Korean freshwater algal flora. Among them, the 5 genera Coronastrum Thompson, Echinospaeridium Lemmermann, Dichtomococcus Korsikov, Dicloster Jao et al. and Siderocystopsis Swale are newly added to the freshwater algal flora of Korea.

The author has investigated the plant flora of Baek-Ah Island during the period from August 4 to August 10 1970, and found that the flora consist of the plants of coastal, temperature and warm zones. The present report lists 81 families, 190 genera and 235 species of plants, of which 73 families and 170 species are medicinal plants.

Losses of nitrogenin the gaseous form were determined with closed systems in the filed under different vegetation types. Ammonia volatilization was greatest from the pine stand, and least from the sod stand, and was greatly reduced in all three sites in the rainy season due to the low temperature. There were only insignificant differences in the nitrogen dioxide volatilization from the soil of the three vegetation types. Losses of ammonia and nitrogen dioxide at various soil depth also showed little variation. Evidently the microbial activity responsible for the $NO_2$ loss was relatively unaffected by the changes in temperature and soil moisture content during the investigation.

This investigation was conducted to study the effect of soybean mosaic virus (SMV) on various parameters of nodule formation at different stage of soybean plants. Differences in nodule formation were marked between soybean varieties tested, but nodules were small within soybean varieties infected with SMV. SMV-infection on soybeans were greatly reduced the number, size and weight of nodules, and the earlier the infection of SMV, the greater the reduction of nodules. Maximum reduction(83%) of nodules observed when "Kumkang-Daerip" soybeans were inoculated 2 weeks after seeding, but none occurred 8 weeks or later. Prominent decreases in number of nodules often resulted in an increase in nodu'e sizes in SMV-infected soybean plants.an plants.

This work was carried out to clarify the subaerial diatoms from Yong-neup (swamp) in Mt. Daeam, near DMZ in Korea from May 1968 to Oct. 1969. These subaerial phytoplanktons live in moss, attaching on moss stems and leaves in air. From this investigation, 18 kinds of subaerial diatoms were identified. Among them, 7 species are known for the first time to occur in Korea.

This experiment was carried out the investigation of proper temperature of germination and growth responses of turf grass to different seedling ages. The results were as follows; 1. It was indicated that the proper temperature of germination was 30$^{\circ}C$ of day and 15$^{\circ}C$ of night, and day length was 14/10 hrs. 2. It was observed that 50 days of seedling was excellent with growth components such as number of tiller, length of tillering, number of node and internode length.
