  • The present study was undertaken to classify and describe the oak (Quercus spp). forests on Mts. Kaya, Bisul, Unmun and Kaji in southern Kyongpook Province, Korea by using a reciprocal averaging method (RA ordination) and the methodology of the ZM school of phytosociology. A temporary vegetation table was prepared by the RA ordination. The diagnostic species of the Quercus forests derived from the ordination were compared with the characteristic and differential species of the existing phytosociological vegetation units of the other mountainous areas of Korea. As a result, the forest vegetation was classified into the next vegetation units: Fagetea crenatae Miyawaki et al. 1968; Acero-Quercetalia mongolicae Song 1988; Rhododendro-Qurcion mongolicae Song 1988, 1. Stephanandra incisa-Quercus mongolica community 1-1 Sasa borealis subcommunity, 1-2 Disporum smilacinum subcommunity; Lespedezo-Quercion serratae Takeda et al. 1994, 2. Spodiopogon sibiricus-Quercus serrata community. The Rhododendro-Qurcion mongolicae and the Lespedezo-Quercion serratae correspond to the cool-temperate forests of the northern type and the southen type (Honda 1922), respectively, in the Korean Peninsula. Also some phytosociological problems in Korea were discussed here in detail from the floristic viewpoint in the present study.

  • Habenaria iyoensis Ohwi (Orchidaceae), previously known only from southern Japan and Taiwan, was found in the lowland of Jeju-do. This species is distinguished from the related taxa of Korean Habenaria by 3-nerved sepals, short-cylindrical spurs, and rosette leaves. The local name Ae-gi-bang-ul-nan-cho implies a smaller plant than H. flagellifera. The morphological characters and illustrations of the species are provided with photographs at the habitat.

  • Platanthera brevicalcarata Hayata (Orchidaceae), previously known to be distributed from Taiwan to southern Japan, was found in the Jeju-do, Korea. This species is distinguished from the related taxon Platanthera chlorantha by its small plant size, white sepal with distinct one green vein, and short-cylindrical spur. The local name Young-ju-je-bi-ran is originated from the local name of Mt. Halla. The morphological characters and illustration of the species are provided with line drawing and photograph from the natural habitat.

  • In order to investigate the variations on the seed hardness of Pisum sativum distributed in southern area of Korean peninsula, 10 local strains (Choonseong. Ganghwa, Pocheon, Hadong, Haman, Geumneung, Yeongyang, Boseong, Gochang, Namweon), which located from $34^{\circ}26"N$ to $38^{\circ}11"N$, were selected according to their latitudes and geographical distances. The seeds of these strains were collected and their contents of mannose and galactose were analyzed. Mannose contents in the seeds were variable in the range between the highest 10.351 mg/g (Ganghwa) and the lowest 5.962 mg/g (Yeongyang). The contents of galactose were also represented remarkable differences from 7.050 mg/g (Yeongyang) to 19.314 mg/g (Hadong). The local strains were classified into 3 variation types such as the south central type (Namweon, Yeongyang, Geumneung, Gochang), the central type (Choonseong. Ganghwa, Pocheon) and the southern type (Haman, Hadong) and 1 strange strains (Boseong) according to the geographical climatic type, isopleth of warmth index and the ratio of mannose to galactose, which indicate the hardness of seeds in Leguminosae, ranged from 0.46 to 0.94. The variation types are very significant genecologically as an evidence for microevolution related to natual and artificial selection in cultivated plants.

  • This study was carried out to determine the effect of sowing time on the flowering, growth and yield of Schizonepeta tenutfozia Briquet. Emergence and flowering dates in the sowing time from March 30 to April 30 were earlier than those of the other sowing times. In the sowing time from March 30 to April 30, length and diameter of main stem, number of node per main stem, number of branch per plant and fresh and dry weight of stem were greater than those of the other sowing times. Yield components such as ear length, main stem length and diameter, branches per plant, number of node and ears per plant, yield of stem in fresh and dry were the highest at the sowing time from March 30 to April 30. Optimum sowing time of Schizonepeta tenuifolia Briquet were from March 30 to April 30 in southern areas of Korea.

  • To determine the optimal planting density of wanggol in southern areas of Korea, Gangsan early local, the highest yielding variety was grown under four different plant density. Yield components such as stem length, number of tiller, stem diameter were highest at the plots with 18 cm row spacing and 18 cm plant spacing. Dry cortex and medulla yield were highest at the plots of 18 cm row spacing and 18 cm plant spacing. Judging from the results reported above, at optimum planting density of wanggol seemed to be 18 cm row spacing and 18 cm plant spacing.
