초록

유색칼라 ‘Black Magic’의 노지와 비가림재배(50% 차광) 및 구근 크기가 생육 및 구근 비대에 미치는 영향을 연구하였다. 맹아소요일수는 노지에 비해 비가림 하우스에서 4.2일 단축되었으며 맹아율과 생육은 노지보다 비가림하우스에서 좋았고 구경이 클수록 양호하였다. 노지와 비가림 하우스의 개화수 차이는 없었으나 화경장은 비가림 하우스가 노지에 비해 12.2cm길었으며 구근 크기가 클수록 개화품질이 양호하였다. 연부병 발생률은 노지와 비가림재배에서 각각 19∼83%, 3∼22%로서 노지재배에서 높게 나타났고 구근 비대는 연부병 발생이 적은 비가림재배에서 양호하게 나타났다. 정식시 구근 크기가 증가할수록 구근 비대는 양호하였으며 비가림재배에서의 구경 0.5∼1 cm구는 약 7개월 후에 구중 50.2g,구경 5.7cm로 비대하였다.

Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50% shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22% was found in the rain shelter as compared to the that of 19∼83% in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.
