Volatile fragrance components in 5 kinds of Korean native Lilium were investigated and compared. The volatile components were extracted by SDE (simultaneous steam distillation and extraction) and identified by CC and GC-MS. As a result of the analysis of volatile aromatic ingredient of L. leichtlinii var. tigrinum Nickels., L. concolor var. parthneion Bak., L. tsingtauense Gilg., L. hansonii Leichtl., and L. amabile Palibin., using frozen materials, 60 kinds of volatile compound were identified, which were 28 aldehydes, 9 ketones, 8 alcohols, 5 esters, 5 acids, 3 furans and 2 others. The GC patterns of the aroma components of all samples resembled but the peak areas were different according to species, though all of them are Korean native Liliums.

Eight species of Korean native lilies were used as plant materials and investigated for the effect of temperature, day length, and sucrose on enlargement of bulblet in vitro. enlargement of bulblet was enhanced at $25^{\circ}C$ in most of Korean native lilies tested, meanwhile it was promoted at $20^{\circ}C$ in L. davuricum and L. hansonii. Moreover, enlargement of bublet was promoted under dark in L. concolor var. parthneion, L. distichum, L. amabile, and L. davuricum, to the contrary fresh weight was increased under longer day length in L. hansonii and L. maximowitzii. That of L. concolor var. parthneion and L. cernuum was not affected by light or dark condition. Fresh weight of the bulblets produced in vitro of most Korean native lilies tested was increased with increasing sucrose concentration and best at $120g{\cdot}L^{-1}$ sucrose in medium. However, enlargement of bublet was promoted by $60g{\cdot}L^{-1}$ sucrose in L. tsingtauense and L. cernuum and by $90g{\cdot}L^{-1}$ in L. davuricum. Bulblet enlargement tended to promote by lower rate of scaly leaf occurrence or separating bulblet and it was affected by occurrence of scaly leaf rather than separation of bulblet. However, occurrence of scaly leaf, separation of bulblet, and enlargement of bulblet were more significantly affected by genetic factors, species rather than culture conditions.

Germination percentage of Korean native lily seeds was high at $20-25^{\circ}C$. It was almost 100% in L. cernuum, L. callosum, L. amabile, and L. concolor, 88.0% in L. lancifolium, and 73.0% in L. maximowitzii, respectively. Meanwhile, it was low rate of 34.0%-54.0% in L. distichum, L. hansonii, and L. tsingtauense. Germination was mostly delayed of $15^{\circ}C$ and days to germination were more shortened in species with higher germination percentage. Even though the effect of daylength was not considerable in germination rate, it was promoted in L. maximowitzii but it was delyed in L. hansonii under long day. The effect of soaking in hot PGRs solution in L. callosum, L. cernuum, L. amabile, L. lancifolium, and L. concolor did not show any difference in comparison with non-treatment. However, it was improved by BA in L. maximowitzii. Longer period of cold wet storage resulted in improved germination percentage in L. maximowitzii and L. lancifolium, while it affected decreased percentage in L. distichum and L. hansonii. Days to germination were shortened by longer period of cold wet storage regardless of species. Germination percentage in dry storage was higher under cold temperature than room temperature and under desiccator storage than outside desiccator, it was highest under desiccator storage at $4^{\circ}C$. It was drastically reduced by the non-use desiccator storage at room temperature L. concolor, however it was improved only by the use of desiccator L. maximowitzii for a long time.

The lily symptomless virus (LSV) is the most common virus in Korean native lilies and causes various types of damage to overall plant growth. This study was carried out to investigate the elimination rate of the LSV by the in vitro scale culture (scaling) method in Korean native lilies and to test reinfection rates of the LSV under several field culture conditions of bulb production. Four Korean native lilies (Lilium dauricum, L. distichum, L. lancifolium, and L. maximowitzii) were used and their scales were cultured in vitro for micro-scale formation. The micro-scales were subcultured repeatedly using MS culture medium supplemented with 30 or $90g{\cdot}L^{-1}$ sucrose. The culture conditions were $24{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD with 16 hour daylength using fluorescent lamps and maintained at $22{\pm}2^{\circ}C$. The virus-free bulblets were grown for one to three years in the greenhouse and transplanted to the field in October or March. Virus infection rates were investigated by direct tissue blotting immunobinding assays and measurement of chlorophyll and protein contents. Virus-free plants could be obtained from the 5th subculture of micro-scales in L. lancifolium and L. maximowitzii or from primary culture in L. dauricum and L. distichum. LSV-free plants were reinfected during bulb production in the field. Reinfection rates were higher at older bulb ages and under higher planting density. The plants planted in October and at inland Gyeongsan had higher infection rates than those planted in March and at coastal area Pohang. The reinfection rate of L. maximowitzii was higher than those of L. dauricum and L. lancifolium. The LSV-infected plants had lower chlorophyll contents and unchanged protein contents compared to virus-free plants.

This study was carried out to breed a self-compatible variety of Tiger Lily from the seedlings originated from Chinju city, Gyeongsangnam-do. The morphological characteristics, ploidy, and the resistance of seedlings to virus infection were investigated. A progeny test was also conducted to examine whether the propagated progenies had the same characteristics as the mother plant. The self-compatible diploid lily variety developed in this study showed a tall type like native triploid lily, Lilium tigrinum, and bulbils were formed on both lily varieties. The morphological characteristics of the flowers and leaves were not much different between the varieties, while the size of the bulbils and bulbs showed significant differences. The percentage of seed generation by self-pollination was 72.6% for the self-compatible variety, while there was no seed generated for native triploid lily. The number of chromosome was 2n = 26 (x = 13, diploid) for the self-compatible variety, while 2n = 39 (x = 13, triploid) in native lily variety. The progenies of the self-compatible diploid lily variety showed the same characteristics as those of its mother plant in morphology, seed germination, and polyploidy. The mother plant of the self-compatible diploid lily variety showed 58% pollen germination and the 2-year-old and 3-year-old progenies showed similar germination percentages. The pollen grains of Korean native triploid lily, however, never germinated.

This study was carried out to investigate the effects of hot solution soaking and chilling treatment on sprouting and enlargement of bulblets obtained through in vitro culture in Korean native lilies with ornamental values. In vitro bulblets of Lilium cernuum, L. hansonii, L. hansonii for. mutatum, L. leichtlinii, and L. tsingtauense were soaked in distilled water or 100 $mg{\cdot}L^{-1}$ $GA_3$ and $GA_{4+7}$ solution maintained at $35^{\circ}C$ for two hours (hot water treatment) and/or exposed at $4^{\circ}C$ for 0, 4, or 8 weeks (chilling treatment) and then planted in plastic trays filled with media and grown in a greenhouse at $20^{\circ}C$ and under 16 h photoperiod. In all species, no bulblet propagated by tissue culture sprouted without chilling or hot water treatment due to dormancy. For dormancy breaking, $GA_{4+7}$ hot solution treatment increasing sprouting by 55-96%, whereas distilled water or GA was not effective in sprouting. Chilling treatment for 4 weeks induced sprouting by 50-70% in L. cernuum and L. leichtlinii, whereas 8 weeks was needed for sprouting of L. hansonii and L. hansonii for. mutatum. Combined treatment of hot water and chilling treatments synergistically promoted sprouting. Especially, in L. cernuum and L. hansonii, $GA_{4+7}$ hot solution soaking prior to chilling for 4 weeks promoted sprouting by 35-45% compared with the reverse order. Enlargement of bulblets resulted from increase in fresh weight and diameter was promoted by the treatments that increased the sprouting percentage of bulblets. Only in L. cernuum, shoots emerged from bulblets soaked in hot $GA_{4+7}$ solution or chilled at $4^{\circ}C$ and shoot emergence rate was highest in bulblets soaked in hot $GA_{4+7}$ solution and then chilled for 8 weeks. From these results, the most effective method for bulblet sprouting and enlargement was to soak in hot $GA_{4+7}$ solution and then chill for 4 weeks in L. hansonii, hansonii for. mutatum, and leichtlinii, and to soak in hot $GA_{4+7}$ solution and then chill for 4 weeks in L. cernuum and tsingtauense.

To develop Korean native lilies as mini-potted plants, the effects of plant growth retardants on inhibiting stem elongation and improving flowering rate were evaluated. Bulblets of Lilium concolor var. parthneion (5-7 g) and L. dauricum (3-4 g fresh wt) derived from in vitro culture and then enlarged by field culture were applied with 0, 25, 50, or $100mg{\cdot}L^{-1}$ ancymidol, diniconazole, and uniconazole through bulb dipping, foliar spray, and drench. In L. concolor var. parthneion, uniconazole dipping most effectively reduced plant height by 60.7-78.3% depending on concentration compared with control without decreasing flowering percentage. In L. dauricum, dipping into diniconazole solution significantly retarded the plant height by 70.0-86.3% and improved flowering percentage by 8.3-18.2% compared to control of 0%. Drench of $25-50mg{\cdot}L^{-1}$ ancymidol was also effective on inhibition of stem elongation and improvement of flowering rate. Therefore, dipping into $50-100mg{\cdot}L^{-1}$ uniconazole solution in L. concolor var. parthneion and dipping into $25mg{\cdot}L^{-1}$ diniconazole solutions or drench of $25mg{\cdot}L^{-1}$ ancymidol in L. dauricum can be useful to produce the mini-potted plants.
