This study was conducted to determine feasibility of production system of Perilla frutescens leaf-stem by fertilizing of Sta-Green in pots. Germination rate of Perilla frutescens seeds collected in 2002 was $7\%$, also germination rate of seeds collected in 2003 was $62\%$, while germination rate of seeds collected in 2004 was above $93\%$. Seed germination rate of Perilla frutescens collected in 2004 were higher than seed gathering in 2002. Especially, plant growth and yield of Perilla frutescens grown in pot(The pots was filled with soil mixtures of Sta-Green and Peat Moss mixed with 40:60 ratio.) was the highest. These results indicate that leaf and stem production of Perilla frutescens can be improved by fertilizing of Sta-Green in pots.

This experiment was carried out to analyze the essential oils from different parts of Perilla frutescens spp. And to know change of the oil content by a diffenent leaf picking time. The analysis of the essential oils was done with gas chromatography(GC),and the results are as follows. Perilla frutescens spp. contained essential oils mostly in their leaves and stems, although their roots also contained the oils. It was suggested that the optimum leaf-picking time of perilla frutescens var. viridis Mak. on the basis of total essential oils was their flowering period around Aug. 24, and that of Perilla frutescens var. for acuta Kudo was Sep. 14. On the basis of perillaldegyde the optium leaf-picking time of Perilla frutescens var. viridis Mak. and Perilla frutescens var. acuta Kudo was Aug. 24. and Aug. 4. respectively.

Leaf quality and fatty acid compositions of collected perilla related genus and species germplasms such as Perilla frutescens var. japonica Hara, Perilla frutescens var. acuta Kudo, Perilla frutescens var. crispa Decaisne, Perilla frutescens var. for viridis Makino, Mosla punctulata Nakai, Mosla japonica Maxim, Mosla dianthera Maxim were analysized. The number of leaves per tiller and leaf size of perilla germplasms were more and bigger than those of mosla germplasms. Aroma degree of mosla germplasms was higher than aroma degree of perilla germplasms. Mosla germplasms could be utilized in the breeding for high aroma perilla lines. Otherwise, the softness of perilla germplasms was higher than that of mosla germplasms. In case of oil and protein contents, perilla germplasms was higher than mosla germplasms, however compositions ratio of fatty acid, especially linolenic acid of mosla germplasms was higher than that of perilla germplasms, therefore mosla germplasms could be utilized as breeding materials with high linolenic acid for industrial oil. The linolenic acid with excellent quality and unsaturated fatty acid showed negative correlation with oil content, protein content and saturated fatty acids.

The purpose of this study was to analyze the chemical components of Perilla leaf(frutescens Britton var. scuta Kudo) according to the making process, and to examine Hunter's color value and sensory evaluation of Jasosuksu by extraction time. Perilla leaves were prepared in three types; fresh leaf, dried leaf in the shade and roasted leaf after being dried in the shade in order to make Jasosuksu. The results of the research were as follows: Free sugars(sucrose, glucose, fructose) and organic acids(citric acid, tartaric acid, malic acid, succinic acid) were present in the fresh leaf, dried leaf and roasted leaf. $15{\sim}16$ kinds of amino acid including aspartic acid were determined in the fresh leaf, dried leaf and roasted leaf, and the major free amino acids were serine, aspartic acid, and glutamic acid. The major total amino acids of tile fresh leaf, dried leaf and roasted leaf were glutamic acid, histinine, and glycine. The major fatty acids of Perilla leaves were palmitic acid, linolenic acid, and linolenic acid. The content ratio of linolenic acid in fresh leaves was the highest, but that of palmitic acid was lower than that of dried leaves and roasted leaves. L value, a value, and b value of Perilla leaf were the highest in the roasted leaves followed by the order of dried leaves and fresh leaves. L value and b value of Jasosuksu extracted from roasted leaves were higher than Jasosuksu extracted from dried leaves. The preference of color, flavor, sweetness of Jasosuksu extracted from dried leaves was the highest when extraction time was 10 min. at $70^{\circ}C$, but that of Jasosuksu extracted from roasted leaves was the highest when extraction time was 15 min. at $70^{\circ}C$. The preference of color, flavor, taste of Jasosuksu extracted from roasted leaves was higher than that of Jasosuksu extracted from dried leaves.

Perilla frutescens, which comprises var. frutescens and var. crispa, has been cultivated traditionally in Asian countries as an edible oil, leaf vegetable, and medicinal crop. To evaluate the lipophilic phytonutrient properties of P. frutescens, we selected 54 Perilla accessions [19 landraces of var. frutescens (FL), 22 weedy type var. frutescens (FW), 9 weedy type var. crispa (CW), 2 cultivars of var. frutescens widely cultivated for seed oil (FCS), and 2 cultivars of var. frutescens cultivated as a leaf vegetable (FCL)] and analyzed their seeds and leaves for vitamin E, squalene, and phytosterols. Among the four vitamin E isomers analyzed, ${\gamma}$-tocopherol was the major form of vitamin E in seeds, whereas ${\alpha}$-tocopherol was the major form in leaves of all types of P. frutescens. The highest total vitamin E content in seeds was present in FL ($170.0mg{\cdot}kg^{-1}$), whereas that in leaves was highest in FCL ($358.1mg{\cdot}kg^{-1}$). The highest levels of squalene in seeds and leaves were in FL ($65.5mg{\cdot}kg^{-1}$) and CW ($719.3mg{\cdot}kg^{-1}$), respectively. Among the three phytosterols, ${\beta}$-sitosterol occurred in the highest amount in both leaves and seeds of all of the crop types. Phytonutrient contents were comparatively higher in leaves than in seeds of all crop types. All of these results suggest that the consumption of leaves and seeds of Perilla crops could be beneficial to human health, as Perilla possesses considerable amounts of various lipophilic compounds.

To evaluate the effectiveness of AMF on the growth of horticultural crops, we compared mycorrhizal and non-mycorrhizal plants, perilla (P. frutescens Britt.), that were inoculated with AMF propagules. In the early stages of growth of perilla, compared to the AMF- perilla seedlings, in AMF+ perilla seedlings at 3 weeks after sowing, leaf length and width increased 17% and 29%, leaf area increased 28%, and shoot fresh weight increased 33%, root total length increased 1%, and chlorophyll content increased 3%. Further at 10 weeks after sowing, compared to the AMF- perilla plants, in perilla plants inoculated with AMF at the sowing and transplanting stages, leaf area increased 21% and 19%, shoot length increased 19% and 17%, root fresh weight increased 17% and 20%, and chlorophyll content increased 5.1% and 4.8%, respectively. Moreover, at 14 weeks after sowing, compared to the AMFperilla plants, in perilla plants inoculated with AMF at the sowing and transplanting stages, the number of leaves increased 16% and 20%, root fresh weight increased 16% and 17% significantly. Further, leaf fresh weight increased 9% and 11%, shoot diameter increased 4.5% and 7.3%, and chlorophyll content increased 1.5% and 2.5%, respectively. The levels of many macronutrients and micronutrients were tended to be significantly higher in AMF+ plants than in AMF- plants, supporting the association between AMF and enhanced growth of plants grown from AMF+ seedlings.

To better understand the morphological variation for Perilla crop in different areas of China, we studied the morphological variation in 87 accessions (84 cultivated var. frutescens and three cultivated var. crispa) from high latitude (Northeast China) and middle latitude (North and Northwest China) areas of China by examining seven quantitative and 10 qualitative characters. Analysis of the morphological variation determined that there was significant morphological differences in five quantitative traits between cultivated var. frutescens and cultivated var. crispa, including effective number of branches (QN2), number of internodes (QN3), number of branches (QN4), length of the largest inflorescence (QN5), and days from germination to flowering (QN7). However, two quantitative traits-plant height and number of florets of the largest inflorescence-did not show any significant differences between cultivated var. frutescens and cultivated var. crispa. In addition, significant differences for six quantitative traits were found between the accessions of cultivated var. frutescens originating from high and middle latitude areas in China, which included QN2, QN3, QN5, number of florets of the largest inflorescence (QN6), and QN7. Principal components analysis (PCA) identified five quantitative characters [plant height (QN1), QN2, QN3, QN4, QN7] and six qualitative characters [fragrance of plant (QL1), color of reverse side of leaf (QL3), degree of pubescence (QL5), color of flower (QL6), shape of leaf (QL7), and hardness of seed (QL10)] that contributed to the positive direction on the first axis. The other quantitative and qualitative characters contributed to the negative direction on the first axis. Most accessions of cultivated var. frutescens and cultivated var. crispa were clearly separated by the first axis. In addition, most accessions of cultivated var. frutescens are from high latitude and middle latitude areas that were clearly separated by the first axis, except for several accessions. The findings from this study will provide useful information towards understanding the morphological variation of Perilla crop according to geographical distribution in high and middle latitude regions of China.
