In 2001, extremely cold air covered Korean peninsula during mid-January, recording - 29.2$^{\circ}C$ in Cheolwon region in Kangwon province. As a result, 4 cities or department below -$25^{\circ}C$ and 10 cities or department between 20 to -24.9$^{\circ}C$ were under the anxiety of cold injury in peach and grape. This survey and investigation was carried out to elucidate the characteristic symptoms of cold injury in peach and to obtain the basic information about the phenomenon, which could be occur in low air temperature.(omitted)

Infection rate of Chrysanthemum stunt viroid (CSVd) in 64 commercial chrysanthemum cultivars cultivated in Korea ranged from 9.7 to 66.8$\%$. Symptoms on leaves of CSVd-infected chrysanthemum included yellow spots, chlorosis, vein clearing, vein bending and crumpling. CSVd induced flower malformation in 'Scot', color change in 'Sharotte', and color breaking in 'Sharon'. CSVd caused reduction of plant height, leaf size, flower size and the flowers number by $32-50\%,\;26-35\%$, $14-36\%\;and\;14-75\%$, respectively. In conclusion, CSVd affected plant height, leaf size and flower quality in chrysanthemum plants.

Asia has 60% of the world population and only about 34.5% of the world arable land. However, Asians traditionally consume very large amount of horticultural produce and depend heavily on vegetables for the sources of horticultural food crop. The vegetable production in Asia is highly intensive and multiple and successive cropping are routinely practiced. Concomitant with the rapid economic growth in many east Asian countries, the demands for high-quality horticultural crop have been drastically increased among many Asians and their interest in high-quality products, outstanding cultivars, machinery and equipment, production technology has been sharply increased in recent years. It is therefore believed that establishing and maintaining closer and regular relations among scientists and societies could provide an excellent momentum for promotion of horticulture on a global basis and both the ISHS and the ASHS could play decisive roles for this kind of promotion.

"Hyehwa" an Asiatic lily cultivar was released in 1998 at National Institute of Horticultural and Herbal Science (RDA), Suwon, Korea. The cross was made in 1991 between Asiatic lily "White Bird", a white colored, and "Avignon", an unspotted scarlet red colored. It was preliminarily selected as A93-20 in 1993. Its multiplication, bulbing growth and flowering characteristic tests were conducted from 1994 to 1998. A new cultivar "Hyehwa" flowers in middle of June and grows 98.7 cm in height. Flowers bloom upward-facing, thick orange (RHS, 28A). Year-round flowering is possible by storage of the bulb under $-1.5^{\circ}C$ conditions. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. Botrytis disease control is needed in the wet season.
