施設하우스內 栽植密度가 양미나리의 生育과 收量에 미치는 影響

This study was investigated to find out the optimum planting densities of Apium graveolens L. about growth characters, yield components and yield at 9 planting densities by transplanting culture. The results obtained are summarized as follows ; 1. Studying the correlationship, the highly negative significances were found between planting densities and petiole weight, planting densities and plant weight, respectively. 2. Plant hight was longest in spacious planting, and was short in dense. 3. Petiole yield was thinkest in planting densities(50×35 ㎝), and was thin in planting densities(40×25㎝). 4. Yield of petiole was increased in planting densities(50×25㎝), but quality and yield of petiole were highest by optimum planting densities (50×35㎝).
