  • The objective of this research was to investigate the effects of planting date, root pruning and uprooting on growth, yield and budding ratio of 'Seolhyang' strawberry (Fragaria${\times}$ananassa Duch.). Planting dates of plantlets with 60 ~ 70 days old were September 7th, September 14th and September 21th. Root pruning rates were controlled to 25% (RP 25) or 50% (RP 50) before transplanting. In the uprooting treatments, the plantlets were pulled out on root media and were replanted into same bed at 10 days (UR 10) and 20 days (UR 20) after transplanting. The delayed planting dates of plantlet resulted in the suppressed growth of plant, reduced yield, and slight earlier appearance of flower buds. The RP 50 treatment showed the lowest value among root pruning treatments in growth and yield, but appearance of flower buds slightly fall behinds. The UR 20 treatment only made flower budding earlier by 6 days than non-treatment. All of root stress treatment was appeared to decrease vegetative growth and yield except the RP 25 treatment. Above results imply that strong root stress was required to emerge second flower bud earlier but which reduced overall growth and yield in 'Seolhyang' strawberry.

  • A rose cultivar "Haedoji" developed at the Jeollanamdo Agricultural Research and Extention Services (JARES) is a standard type with deep Red flower. From 2000, two cultivars 'Vital' and 'Cardinal' were examined for horticultural characteristics and were included in cross-combination in 2003. Cultivar 'Vital', a vigorous standard type, first preference with red flower, was used as a mother plant and cultivar 'Cardinal', a red flower standard type with light color, was used as a pollen-donor plant. seventeen six breeding lines were selected in 2004 based on flower shape, flower color and abundance of petal numbers on the first selection. two breeding lines were selected in 2004 based on powderly mildew and vigor on the second selection. For three years, from 2005 till 2007, one breeding lines were selected and examined for their productivity, and then cultivar "Haedoji" was developed because of distinctive characters such as light red color flower, upright stem, long vase-life and Resistance to the Powderly Mildew. A standard type with intermediate sized flower, cultivar "Haedoji" shows in average 9.2 cm flower diameter, 62.0 cm flower stem length, and 9.5 days vase-life. The average productivity for three years was $167.3stems{\cdot}m^{-2}$ per year and increased 2% compare to cultivar 'Tiamo' with $163.9stems{\cdot}m^{-2}$ per year.

  • To investigate the effect of night minimum temperature on growth and flower development in standard type chrysanthemum 'Baekina' during winter season, morphological characteristics and physiological disorders were compared with standard chrysanthemum 'Jinba'. Although the flower budding of 'Baekma' was delayed about 2 to the days compared with 'Jinba', the days to flowering of 54 to 59 showed no difference between the two cultivars. Flowering was delayed as minimum temperature decreased at night. The length and weight of cut flower decreased in the two cultivars as minimum temperature increased at night. In 'Baekina', the number of petals at 16 showed the highest values among other temperatures. Whereas there was no significant difference among the temperature treatments in 'Jinba'. Rosette occured only in 'Baekma', and the ratio was 11.1% at 14, 55.6% at 16, and 56.1% at 18. The inhibition of flower budding appeared only at 14 in the ratio of 17.3% in 'Baekma' and 4.0% in 'Jinba'.

  • Tubers(4-5cm diameter) of Zantedeschia 'Black Magic' were used to study the induction of flowering in GA3 soaking times and concentration. The GA3 soaking were 10 seconds and 30 minutes at the GA3 concentrations of 50, 100, 250, and 500 mg·L1. The time to emergence in GA3 treatment were 1.1~4.0 days shorter than control Growth characteristics were good in GA3 treatment but that was no significance in GA3 soaking time and concentration. When GA3 soaking time and concentration were increased, days to flowering was shorter, but flower stalk length, flower stalk width, flower length, flower width were no difference. The number of flower per tuber was most as 4.0~4.3 in 250~500 mg·L1 GA3 concentration and that was about 2 times compared to control. The normal flower ratio and bulb enlargement were similar compared with GA3 soaking time and concentration. GA3 250~500 mg·L1 treatment is necessary for improvement of number of flowers per bulb.

  • This study was performed to identify the effect of fertilizer application and planting method on growth and yield of 'Seolhyang' strawberry during seedling raising. According to the concentration of fertilizer applied, the height of daughter plants was the highest at an EC of $0.8dS{\cdot}m^{-1}$. Leaf number and crown diameter were greatest at an EC of $0.6-0.8dS{\cdot}m^{-1}$. In the first measurement, root number was highest in non-fertilizer application, while root weight was heaviest in non-fertilizer application and EC $0.4dS{\cdot}m^{-1}$. The higher the concentration of fertilizer applied as culture media, the lower the growth rate. Thirty days after planting on the main field, plant height and number of new leaf were highest at an EC of $0.8dS{\cdot}m^{-1}$. However, no significant difference was found in leaf length and width and chlorophyll content according to fertilizer application. Marketable yield of 25 g or higher was greatest in EC $0.6dS{\cdot}m^{-1}$. In contrast, no significance was found in total marketable yield at an EC of $0.4-0.8dS{\cdot}m^{-1}$. Aconsistent pattern was exhibited in the growth of 1-5 harvesting flower clusters according to planting method. The length of leaf and flower cluster was short and chlorophyll content was low, when bed soil was removed 100% in harvesting of the first flower cluster. In all treatment, leaf length was shortened until harvesting of the second and third flower cluster, but rapidly lengthened in harvesting of the third and fourth flower clusters. Moreover, the length of flower cluster had a increasing tendency from harvesting of the third flower cluster. However, chlorophyll content was reduced continuously until harvesting of the fifth flower cluster, and was lowest in harvesting of the fourth flower cluster without removal of bed soil. Total yield was greatest in treatment of crown removal in bed soil between November and May. Late marketable yield between March and May was highest in treatment of 100% bed soil removal, followed by treatment of crown removal. Marketable yield of 25 g or higher was greatest in treatment of crown removal between December and February, while greatest in treatment of 100% bed soil removal between March and May.

  • This experiment was conducted to investigate the quality of wild flowers and mixed wild flower silages. Silage materials employed ochardgrass and mixed wild flower (orchardgrass, white clover, Achillea sibirica Ledeb., Coreopsistinctoria Nutt., Rudbeckiabicolor Nutt., Centaureacyanus L.). Six kilograms of silage materials cut from each treatment were divided into 3 containers, packed by vacuum, and fermented for 40 days. The orchardgrass silage showed significantly higher contents of crude protein than that of mixed wild flower silage. But the neutral detergent fiber and acid detergent fiber contents of orchardgrass silage were significantly lower than those of mixed wild flower silage. pH and butyric acid of orchardgrass silage were significantly lower than those of mixed wild flower silage, and significantly higher in lactic acid contents. It appears that water soluble carbohydrates needs to be supplemented, being grounded on the results above, into wild flower materials both with high fiber materials and with low substances which need lactic acid fermentation.
