Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.

This study was conducted to develop the clonal propagation technique through in vitro culture using basal stem explants in Phalaenopsis hybrid grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when basal stem explants were cultured on VW medium containing 30g/L sucrose, 500 mg/L activated charcoal, 150 ml/L coconut water, 1 mg/L NAA, 5 mg/L 2iP and 2.5g/L gel rite. PLBs transferred to Hyponex medium were regenerated to plantlets. Plantlets transferred to plastic pots containing spagnum moss were developed and successfully acclimatized under greenhouse. The flower was bloomingly opened in plants regenerated from basal stem explants. The flower was not different from both mother plant and plant induced through clonal propagation of Phalaenopsis hybrid.

Optimmum cultivation period was determined for producing seed bulb of Korean native Allium wakegi Araki in vitro in hydroponic culture. The growth gradually increased during cultivation period. In general, plants grown for 5 months produced significantly the highest bulb number and bulb fresh weight per plant. Raising the cultivation period from 1 to 5 months remarkably increased seed bulb yield.

High productivity of ginger (Zingiber officinale Roscoe) was obtained from the rhizome produced by shoot-tip culture with Korean native variety, Seosanjong. Seed rhizomes induced by shoot-tip culture were successfully established in the field. The rhizomes induced by both plant or rhizome were higher in emergence rate and faster in days to emergence than those of home seed production. The seed rhizome production induced by shoot-tip culture was two times heavier than that of home seed production. These results suggest that shoot-tip culture might be one of mass propagation methods in seed rhizome of ginger plant.

This study was conducted to examine the influence of different transplanting dates on rice quality and starch properties (morphology and pasting properties) of rice varieties that may be used for the production of rice flour. Three rice flour varieties, 'Seolgaeng', 'Hangaru', and 'Milyang317', were transplanted on May 20, May 30, June 10, and June 20. The peak viscosity decreased with a delay in the transplanting date. However, the amylose content increased with a delay in the transplanting date, whereas that of protein decreased. Amylopectin short-branch chain content increased in the rice varieties that were transplanted on May 30. The morphology of the starch granule of the varieties was determined by SEM. No apparent external difference in the starch granules was observed for the different transplanting dates. These results indicate that the transplanting date influenced the amylopectin structure and pasting properties, which led to changes in the physicochemical characteristics of rice starch.

A red grafted cactus of Gymnocalycium mihanovichii 'Red King' was bred by the Cactus Research Institute, Gyeonggi-do ARES. in 2007. A crossing between 'Redjewelry' and 'GG024824' in 2005 was obtained 135 seedlings. 'Red King' was finally selected through the test of specific growth and coloring characteristics in 2007. The color of body and tubercles is red. The shape of glove is flat round with 8~9 ribs. Spine is short length and light brown color. Growth is fast as 6 month after planting to reach 36.8 mm in diameter. Propagation ability is good as to set as many as 14.1 tubercles.

A new graft cactus (Copiapoa scopa) cultivar 'Redstone' was developed at Cactus Research Institute, Gyeonggi-do A.R.E.S, in 2007. GCP563 and GCP618 were crossed in 2004 and we got 9 seedlings from this combination. After pedigree selection in 2005, one cultivar was finally selected through the test of specific character in 2007 and named as "Redstone". "Redstone" cultivar has red brown color and round globose shape with 15 ribs and its spines are black. This cultivar is able to produce 26.8 offshoots per plant. 'Redstone' cultivar has higher productivity and more slow growth than Copiapoa scopa cultivar.

A new graft cactus (Chamaecereus silvestrii f. variegata) cultivars "Yellow Ttree" was developed at Cactus Research Institute, Gyeonggi-do A.R.E.S. in 2007. GC013001 and GC0110703 were crossed in 2005 and we got 42 seedlings from this combination. After pedigree selection in 2005, one cultivar were finally selected through the test of specific character in 2007 and named as "Yellow Ttree". "Yellow Ttree" has cylindrical shape of yellow color with 13~14 ribs. Formation of its offshoots is concentrated on the lower part of the plant. This cultivar is able to produce 13.9 offsets shoots per plant and its offshoots are hard.
