Abstract

This study was conducted to establish a standardized process for plug seedling production of Chinese chives for hydroponics. The research aimed to determine the germination characteristics and to investigate the effect of sowing amount and leaf cutting on growth during plug cultivation. The results showed that ‘Speedgreen’ had the highest germination rate, while the traditional variety ‘Dume’ exhibited a significantly lower germination rate. The germination rate of the ‘Speedgreen’ was 92% in 3 days, while the ‘Greenbelt’ reached 66% on the 3rd day and 83% on the 6th to 7th day, and then stopped increasing. The germination rate of ‘Dume’ was very low, less than 1% until the 7th day and about 24% on the 14th day. The mean germination time (MGT) was 2.28 to 1.38 days for the ‘Speedgreen’ and ‘Greenbelt’ as commercial varieties, but 9.22 days for the ‘Dume’. The coefficient of velocity of germination (CVG) and germination index (GI) were also the best for the ‘Speedgreen’. In the results of the water absorption characteristics of the seeds, the maximum water absorption rate of the ‘Dume’ was about 85%, while the ‘Speedgreen’ and ‘Greenbelt’ reached 97%. In a study on increasing the number of tillers, the increase in the number of leaves was not proportional increment to the seeding amount, and the increase in the number of leaves due to cutting treatment tended to increase as the cutting height increased. It would be good to sow about 8 to 10 seeds per cell in the plug tray. In particular, stem cutting as a treatment to induce increased tillering was deemed effective when performed at a point at least 5 cm above the subterranean part of the chive and that treatment will increasing fresh weight.

본 연구는 부추의 양액재배를 위한 공정육묘 방법의 확립을 위해 부추의 발아특성과 플러그 육묘시 파종량과 줄기절단을 통한 생육증대 효과를 구명하고자 수행하였다. 부추의 발아는 스피드그린이 가장 우수하였고, 재래품종인 두메부추는 발아율이 현저히 떨어졌다. 발아율에 있어서 스피드그린 품종은 3일만에 92%의 발아율을 보였으며, 그린벨트 품종은 3일째에 66%정도에서 6－7일째에 83%정도 도달하여 증가가 멈추었으며, 두메부추는 7일째까지 1% 미만, 14일째에 24%정도로 매우 낮게 나타났다. 평균발아시간(MGT; mean germination time)은 스피드그린과 그린벨트 품종이 2.28－1.38일이었으나 두메부추는 9.22일이 소요되었다. 발아속도계수(CVG; Coefficient of velocity of germination)와 발아지수(GI; germination index)도 스피드그린 품종이 가장 우수하였다. 종자의 수분흡수 특성을 보면 재래품종인 두메부추의 최대 수분흡수율이 85% 정도인데 반해 상용화된 스피드그린과 그린벨트 품종은 97%에 달해 차이가 있었다.

분얼수 증대를 위한 연구에서 파종량에 따라 엽수증가가 비례하지는 않았고, 절단처리에 따른 엽수의 증대는 절단높이가 높을수록 증가하는 경향이었다. 양액재배를 위한 부추육묘시 파종판의 셀당 8－10립 정도를 파종하는 것이 빠른 분얼의 증대에 효과적일 것이라 생각되었다. 특히 절단처리를 통해 분얼을 유도한다면 지제부에서 5cm이상의 높이로 절단하는 것이 분얼이나 생체중 증가에 유리할 것으로 판단되었다.
