The effects of different kinds of supplementary lighting or heating lamps on the yield, cut flower life, and leaf color of cut rose were compared and analyzed. For this purpose, light emitting diode lamp (LED), metal halide lamps (MH), and high-pressure sodium lamps (HPS) as the supplementary lamps, and carbon fiber infrared lamp (NCFI) were installed on hydroponic cultivation bed in a cut rose farm. The yield of cut flower rose and the number of marketable flowers were greatly increased in spring and autumn by HPS treatment, but not in winter. The length of flower stalk was longer than that of control in the spring but decreased in winter. It seemed likely that the shorter flower stalk in winter was due to the shortened period of vegetative growth compared to the control because flowering was promoted by supplementary lighting. Vase life was not different among treatments in the autumn when the lighting time was short, but in winter, it was prolonged to 3 more days by only HPS, compared with the control. Leaf color was significantly affected by light treatment in winter rather than autumn. Leaf color was darkened in all supplementary lamps (LED, MH, HPS) treatment, whereas NCFI was similar to the control in leaf color. In conclusion, HPS is considered to be a very good supplementary lamp because it increases the length of flower stalk and the yield and prolongs vase life in cut roses. Even though NCFI could function as a heating lamp radiating a lot of heat, it was considered that the role as a supplementary light is unsatisfactory because the number of marketable flowers decreases and the quality index of cut rose deteriorates by NCFI.

A new asiatic lily cultivar 'Point' was derived from a cross between $Lilium$ $concolor$ var. $partheneion$ and 97-5 with orange colored petals made in 2000.

Based on flower color, 'Point' cultivar belongs to orange red group (O-R N30C). There was lots of spots in petal. The flowers had brown stigma and dark brown pollen. The stem color was dark purple. The flowering date was July 8. The plant height was 88.2 cm and flower numbers were 5.4 ea. The length and width of petal were 6.3 cm and 3.2 cm, respectively. The flower size was smaller than that of 'Prato' cultivar. The number of leaves was 12.2 ea. The length and width of leaves were 9.2 cm and 1.1 cm, respectively. The weight and circumference of bulb were about 24.6 g and 11.6 cm, respectively. 'Point' cultivar had resistance to bulb rot disease. The flowering duration was 16.1 days. The preference was good to 4.1 on 5 grades. 'Point' cultivar was registered as a new variety with No. 3446 in Korea Seed and Variety Service on April 2011.

A new gerbera cultivar 'Paspin' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2009. A cross was made between 'Lilabella' and 'Mephisto' with purple and semi-double in 2005. After investigation of the characteristics for five years (from 2005 to 2009), it was selected specially as a cut flower. The 'Paspin' cultivar has a pastel pink flower color (RHS R52B) with green disc center and semi-double flower. It has large-sized flowers which average flower diameter is about 12.8 cm. And inner ray floret and disc diameters are 7.87 cm and 2.57 cm, respectively. It has an adequate peduncle height of 48.6 cm, and a longer vase life of 10.8 days. It is vigorous in growth and also adaptable to the local cultural environments of Korea. It is expected that if the 'Paspin' cultivar will be planted, the royalty fees to be paid to other countries can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.

In order to determine the relationship between water content and flower qualities of oriental hybrid lily cv. 'Siberia' cut flower, flowers were subjected to dry and cold storage at $5^{\circ}C$ for 3, 6, and 12 days and subsequently exposed to ambient temperature ($26^{\circ}C$) in bottles with water for up to 16 days. Flowers stored at $22^{\circ}C$ in dry condition for 3 days were used as the control. Changes in fresh weight, moisture content, water balance, flowering stages, osmolality and vase life of cut flowers were observed. Flowers treated with cold and dry storage had higher moisture content compared to control sample. However, this trend was evident only for 3-day cold and dry stored sample during the whole storage period. The fresh weight of cut flowers increased gradually when the samples were transferred to ambient temperature in water bottles and then declined steadily before reaching the peak in between 6-8 days of vase life. However, the changes of fresh weight of control sample were substantially faster than samples pre-treated with cold and dry storage. This was also correlated with the water balance of cut flower as it reached the minus (-) value in 6-8 days of vase life at ambient temperature. Cut lily flowers showed high osmolality values corresponding with the duration of dry storage regardless of low or higher temperature. However, osmolality had no effect on vase life since flower stem absorbed water rapidly at the end of dry storage period. Our vase life results suggest that cold and dry storage of lily cut flowers for a certain period could ensure longer vase life at ambient temperature. It was observed that prolonging the storage period at cold and dry condition for more than a week significantly increased bud abortion, reduced longevity of flowers and reduced the vase life of cut flowers. On the other hand, the shorter cold and dry storage treatment delayed the bud opening and senescence of the flowers, thus, slowering the normal maturation and aging. Results indicated that dry and cold storage at $5^{\circ}C$ for 3 days was effective in maintaining and preserving overall quality and vase life at ambient condition of oriental hybrid lily cut flowers.
