Oriental계 백합의 종구생산에 있어 재배지역 및 정식기가 생육 및 구근비대에 미치는 영향 = Effects of cultivation area and planting time on bulb growth and enlargement of Lilium oriental hybrids in seed bulb production

다국어 초록 (Multilingual Abstract)

This study was conducted to investigate effects of cultivation area and planting time on bulb growth and enlargement of Lilium oriental hybrids in seed buld production. Planting time was divided into three periods such as May 15, 30, June 15 and Cultivation areas were alpine Daegwallyong and low land Kangnung area. The results were as follows:
1.The temperature of Daegwallyong from June to September was around 16-18℃ which was the optimum temperature for growth of Lilium oriental hybrids compared with above 20℃ of Kangnung area.
2.The bulb emergence rate in Kangnung area was 1-3 days faster than Daegwallyong. As the planting time was delayed, the bulb emergence rate was faster.
3.There was no significant difference in plant height between cultivation area and cultivars, but as the planting time was delayed, the plant height in Kangnung was much longer than Daegwallyong.
4.The chlorophyll content was high in the early planting time and that in Daegwallyong was higher than Kangnung.
5.The fresh and dry weight of leave was increased in Daegwallyong cultivation, compared with Kangnung.
6.The growth of underground parts such as numbers and length of basic roots and root system of stem roots in Daegwallyong was much better than Kangnung.
7.Virus infection rate in Daegwallyong was lower than Kangnung, but in the phytophthora blight and leaf blight vice versa.
8.The faster the planting time was, the higher the bulb weight was. And the bulb weight in Daegwallyong was 93% higher than Kangnung.
