암면 큐브 육묘에서 급액 시점에 따른 파프리카 묘의 소질 변화

This study was conducted to investigate the seedling qualities and growth of paprika according to various irrigation points (Ips) (30, 40, 50, 60 or 70%) of the water contents of rockwool cube for raising seedlings of paprika. Growth degree of paprika seedlings was positively correlate with various irrigation points. In particular, paprika seedlings with IP 30-40% and IP 50-70% treatments were significantly higher than those with other treatments. Leaf area of seedlings was 50-100% wider in those with IP 50% and IP 40% treatments than those with other treatments, therefore dry weight was IP 30-60% heavier. The dry weight of more than IP 50% treatments had no significant differences. Leaf area (Y1) had a significant relation with the irrigation point (x) as Y1 = 48.311x + 133.7 (R2 = 0.9116**). Also dry weight (Y2) of the seedlings showed a linear regression equation as Y2 = 0.1584x + 0.8616 (R2 = 0.8853*). Considering the leaf area and the dry weight of irrigation points for rising seedlings of paprika in this study, the optimum range of the irrigation points in the water contents of rockwool cube is IP 50%.
